What is a commercial industrial oven?
An industrial oven is a heated chamber, run at about normal air pressure, that holds work at a set temperature. A recirculating fan blows hot air through the chamber, or infrared emitters heat the work directly. The heat comes from electric elements, a gas burner or infrared panels. Drying removes water or solvent. Curing starts a chemical reaction in a coating or resin once the work reaches its target temperature. Baking holds work at heat so a coating, adhesive or material sets or loses moisture. Work goes in as a batch on racks, carts or trucks, or travels through on a conveyor. An exhaust fan carries vapour out. Melting and induction furnaces are a different machine.
This page covers commercial and industrial ovens for coating shops, foundries and factories; laboratory, bakery, kitchen and home ovens are not covered.
How diipl verifies industrial oven manufacturers
diipl checks every industrial oven manufacturer before a buyer meets them. Every seller is GSTIN verified and capacity audited. IEC and the certifications your product and market need (ISO, CE, REACH, BIS) are confirmed before any meeting; Certificate of Origin and EIC inspection are arranged per shipment where required.
For industrial ovens, the capacity audit also covers:
- A heat-up run on the factory floor with the chamber empty, logging air temperature at several points through the volume, to see how even the heat is at the working temperature.
- A soak at the rated top temperature, checking door seals, panel joints and the outer skin for leaks and hot spots.
- For a gas-fired oven, a witnessed burner start with the purge, the flame failure shutdown and the fuel shut-off valve each tested.
- The recirculation fan and the exhaust fan run at full speed, checked for vibration, noise and belt or bearing condition.
- An oven already built for another customer, inspected for panel build, insulation, door fit and controller wiring.
We match your requirement to a manufacturer that has passed these checks and arrange a direct meeting.
Types of industrial ovens we cover
Indian industrial oven manufacturers on the diipl bench build these commercial and industrial types.
| Type | Typical buyers |
|---|---|
| Electric cabinet hot air oven | Plastic and metal part makers that heat treat parts. |
| Electric walk-in and truck-in batch oven | Composite part makers and other plants that cure loaded trucks in batches. |
| Gas-fired walk-in and truck-in batch oven | Plants that age, bond, cure or heat treat loads, including work that releases flammable solvent. |
| Gas-fired conveyor convection cure oven | Powder coating lines that finish parts of varied shape, size and thickness. |
| Electric infrared conveyor cure oven | Coating lines with uniform parts, and plants that cure heavy, thick products. |
Electric cabinet hot air oven
A cabinet oven holds the load on shelves inside the heated cabinet. Electric models heat the air with tubular heating elements and a recirculating blower moves it through the chamber. One published model is rated to 260 °C, has an 18 kW heater, three metal shelves and a blower that sends air down onto the work, and is used for heat treating plastic and metal parts.
Electric walk-in and truck-in batch oven
A walk-in oven has a chamber large enough to roll a loaded oven truck inside. Electric models use heating elements to warm the chamber. One published model is rated to 343 °C, has 7 inch insulated walls and an insulated floor with truck guide tracks, and carries explosion-venting door hardware and a powered exhaust fan for flammable solvents.
Gas-fired walk-in and truck-in batch oven
This is the walk-in body heated by a gas burner instead of electric elements. One published model lists a proportioning gas-fired heater as an option and is rated to 454 °C, with a high-volume fan pushing air sideways through perforated steel walls across the load. The same page describes a solvent-handling design that includes a pressure relief panel, a purge timer and an exhaust fan.
Gas-fired conveyor convection cure oven
In this variant a conveyor carries parts through the oven while gas burners heat the air around them. Natural gas or propane is the usual fuel for convection. A significant benefit of convection curing is that it reaches all surfaces of the part, so it suits highly varied shapes, sizes and thicknesses. The mass of the part is key: heavy parts take longer to heat, which extends the cure cycle.
Electric infrared conveyor cure oven
Short-wave electric infrared bulbs heat the part directly and can give a quick, high-intensity cure in a small space. They must be controlled so the powder is not overcured and burned. They suit uniform parts. Heavy, thick products such as street light poles and counterweights are also good candidates, since convection alone could take hours.
What to specify when buying an industrial oven
A clear industrial oven specification gets you comparable offers and a faster meeting. Share these points with diipl and we match them to the right manufacturer.
| What to specify | Why it matters |
|---|---|
| Heat source and firing type: electric, gas burner or infrared, and direct-fired or indirect-fired | In a direct-fired oven the combustion products enter the chamber and touch the work. In an indirect-fired oven the burner is outside and the oven air stays apart from the combustion gases. The earlier Indian code defines both. |
| Cure or drying schedule, written as a part (metal) temperature and a time | Cure schedules refer to the temperature of the part, not the oven air. One supplier ladder for a polyester powder lists 10 minutes at 193 °C and 14 minutes at 182 °C. Give the maker your powder data sheet. |
| Maximum operating temperature, and the rating of insulation, seals and controller at that temperature | Ratings differ by build. One published walk-in oven, with a gas-fired heater among its options, is rated to 454 °C. State the highest temperature you will ever need, so the maker sizes the heater and insulation for it. |
| Temperature uniformity at your working temperature, and how it is tested | One maker states a uniformity of plus or minus 5 °F at 285 °F, checked by a nine-point profile test in each empty chamber under static conditions. Ask for the figure at your own temperature and the test record. |
| Chamber size, door opening and clearance around the part | Size, thickness and material set the required temperature and dwell time. The opening must be kept small but still leave room for sway and a mis-hung part. Batch ovens should sit close to the powder booth. |
| Air circulation: how many times a minute the oven air is turned over, and the airflow pattern | Recirculation should turn the air over at least 3 times a minute for heat transfer; stringent appearance needs can call for up to 8. Variable airflow can help: gel the powder at low airflow, then raise it. |
| Heat load calculation and the burner or heater rating chosen from it | Heat load comes from the weight of parts and racks, the wall area and the type of opening. It is worked out in heat units per hour, then a safety factor is added before a burner is chosen. |
| Insulation thickness and panel construction | One source says systems houses typically use 6 inch (about 150 mm) thick oven panels for temperatures from 300 to 500 °F. Ask for the panel build, the insulation material and the outer skin temperature at full heat. |
| Exhaust volume and the purge routine before the burner fires | Before the burner fires, the oven volume needs to be exhausted at least four times, following the current oven safety standard. Powder ovens generally need less exhaust than ovens for liquid coatings. |
| Explosion relief, fuel shut-off and ventilation for solvent or gas-fired ovens | The earlier Indian code asked for relief vents on ovens that may contain flammable vapours or gases, fuel shut-off valves that a fire cannot block access to, and mechanical ventilation to outdoors for ovens releasing flammable or toxic vapours. |
| Controls and interlocks: controller, data logging, door switch and process timer | One maker offers a door switch that stops the heater and blower when the door opens, process timers that switch the oven off at the end of a cycle, and a controller with data logging. Ask which are standard. |
| For a conveyor oven: line speed, dwell time including ramp-up, and elevation changes | Designers must allow the time parts need in the oven to reach full cure, including ramp-up, together with line speed. Heavy, large parts typically do not fare well going up and down on a conveyor. |
| For an infrared oven: part shape, emitter control and a cure test on your own part | Radiant energy must reach the coating surface, so part shape matters. One trade source says powder makers' cure times are greatly overstated for infrared. Ask for a trial cure on a real part and for how the emitters are controlled. |
| Nameplate data fixed to the oven | The earlier Indian code asked for a nameplate showing the solvent used, solvent load, purge interval, oven temperature, exhaust blower rating, maximum operating temperature, serial number and the maker's name and address. |

HSN code and ITC-HS code for industrial ovens
The code for industrial ovens depends on how the oven is heated, whether by electric resistance elements, electric infrared emitters or a fuel burner, and, for a fuel fired oven, whether it is built to heat treat metals. Choose the line that matches your machine:
- 85141900 (other, within subheading 851419: furnaces and ovens; electric, for industrial or laboratory use, resistance heated; other than hot isostatic presses, for the manufacture of semiconductor devices on semiconductor wafers) when the oven is heated by electric resistance elements, as in the electric cabinet hot air oven and the electric walk in batch oven.
- 85143900 (other, within subheading 851439: furnaces and ovens; electric, for industrial or laboratory use, other than those functioning by induction, dielectric loss or resistance heated, other than electron beam, plasma or vacuum arc furnaces) when the oven is heated by electric infrared emitters that warm the part directly, as in the electric infrared conveyor cure oven.
- 84178090 (other, within subheading 841780: furnaces and ovens; including incinerators, non-electric, for industrial or laboratory use, n.e.c. in heading no. 8417) when the oven is heated by a fuel burner and is not built to heat treat metals, as in the gas fired walk in oven and the gas fired conveyor cure oven.
- 84171000 (furnaces and ovens for the roasting, melting or other heat-treatment of ores, pyrites or of metals) when the fuel fired oven is built to heat treat metals, for example to age or harden metal parts.
An industrial oven is classified by how it is heated. The tariff puts electric furnaces and ovens in one heading and non-electric ones in another, and the heading for heat treatment machinery and dryers expressly leaves out the electric ovens, so an oven with resistance elements, an oven with electric infrared emitters and an oven with a fuel burner each take a different line. A fuel fired oven built to heat treat metals has its own line in the non-electric heading. A fuel fired oven that only dries at low temperature is argued between the non-electric ovens line and the dryers line, and no code is given for that use.
In India the GST HSN code and the export ITC-HS code come from the same nomenclature. A GST invoice needs only the first 4 or 6 digits, depending on your turnover; the export shipping bill carries the full 8-digit ITC-HS line. The classification is shown here; the applicable GST rate is not. Official source.
A classification is a fact any lookup can give you. The correct code still does not tell you which countries are buying industrial ovens right now, what duty each of them charges on the Indian line, or whether that demand is growing or fading. Those answers come from trade data, not from a code table, and they decide whether a market is worth entering. diipl's free Market Research Report answers them for your machine.

Buying an industrial oven in India
- Ask for a GST invoice that lists the oven model, the heat source and the rated maximum temperature, and keep the maker's drawings and wiring diagram with it.
- Agree the site work before delivery: a level floor, room for the doors and for cart travel, a short run between the spray booth and the oven for batch work, and the power or gas supply point. A gas-fired oven also needs a fuel line with a shut-off valve placed where a fire cannot block access.
- Plan installation and commissioning by the maker's engineer, including a burner start, a purge check and a temperature run on your own load.
- Ask for operator training on loading limits, the controller, the purge routine and the door interlock, so racks are not overloaded and a cycle is not stopped halfway.
- Confirm spares and service: burner parts, flame sensors, thermocouples, fan belts or bearings, door seals, and where the nearest service engineer is based.
- Agree delivery: whether the oven arrives as a finished unit or as insulated panels to be assembled on site, and who assembles, lifts and positions it.
Buying from Indian industrial oven exporters
- Settle the Incoterm in writing and who handles loading, sea freight and insurance for bulky insulated panels, ductwork and any conveyor.
- Match the supply to the site. For an electric oven state the voltage, the number of phases and the frequency. For a gas-fired oven state the gas type and the supply pressure, because burners must suit the type and pressure of the fuel gas.
- Settle the safety route by region before the order. For the European Union, ask which standard the oven is built to: the standard for coating ovens that release flammable vapour, or the thermoprocessing standards for fuel-fired equipment and the electroheating safety standard for electrically heated ovens, and ask for the declaration of conformity that names it. Ovens are not named in the higher-risk machinery lists of the new EU Machinery Regulation.
- For North America, ask whether the fuel train and safety controls follow the oven and furnace fire standard that the site's inspector will apply, and whether the control panel carries a recognised listing mark.
- Ask for the papers an importer of an oven expects: the declaration of conformity or test papers, a wiring diagram, burner and controller manuals, the nameplate data and a temperature survey of the empty chamber. Ask early if the destination wants a Certificate of Origin.
- Ship spare thermocouples, a flame sensor, fan belts and door seals, agree video support for commissioning, and pack so the insulation stays dry and the controller and burner train are padded for sea freight.

Industrial Oven: frequently asked questions
Who makes industrial ovens in India?
Manufacturer names are not published on diipl. You describe the oven you need: part size, load, process temperature, heat source, and whether the coating releases solvent. diipl then picks a maker whose GSTIN has been verified and whose factory has been audited, confirms it holds an Importer Exporter Code and the certificates your destination expects, and sets up a one-to-one meeting. For an oven, the audit includes a heat-up run with temperature logged at several points in the empty chamber.
What size, temperature and heat source should I ask for in an industrial oven?
Start from the part: its size, thickness and weight, and the load per hour. These set the chamber size, the heat load and the dwell time. Then state the cure or drying schedule as a part temperature, the highest temperature you need, the heat source, and how the load goes in, by rack, cart or conveyor. Ask for the airflow, insulation and exhaust design, and the temperature uniformity at your working temperature.
Which standards or certifications apply to industrial ovens?
In India, IS 11332 is the code of practice for industrial ovens, and BIS shows its 1985 edition as withdrawn and superseded by a revised edition. For export, EN 1539 covers coating ovens that release flammable vapour, the EN 746 series covers thermoprocessing equipment, and NFPA 86 is the oven and furnace fire standard listed in OSHA guidance. Your buyer's region decides which to follow.
What is the HSN code for industrial ovens?
The code for industrial ovens depends on how the oven is heated, whether by electric resistance elements, electric infrared emitters or a fuel burner, and, for a fuel fired oven, whether it is built to heat treat metals: 85141900 when the oven is heated by electric resistance elements, as in the electric cabinet hot air oven and the electric walk in batch oven; 85143900 when the oven is heated by electric infrared emitters that warm the part directly, as in the electric infrared conveyor cure oven; 84178090 when the oven is heated by a fuel burner and is not built to heat treat metals, as in the gas fired walk in oven and the gas fired conveyor cure oven; 84171000 when the fuel fired oven is built to heat treat metals, for example to age or harden metal parts. An industrial oven is classified by how it is heated. The tariff puts electric furnaces and ovens in one heading and non-electric ones in another, and the heading for heat treatment machinery and dryers expressly leaves out the electric ovens, so an oven with resistance elements, an oven with electric infrared emitters and an oven with a fuel burner each take a different line. A fuel fired oven built to heat treat metals has its own line in the non-electric heading. A fuel fired oven that only dries at low temperature is argued between the non-electric ovens line and the dryers line, and no code is given for that use. The export shipping bill carries the full 8-digit line and a GST invoice its first 4 or 6 digits, depending on your turnover, so confirm the line for your exact machine before you file. The HS code finder lists every 8-digit line.
Can Indian manufacturers export industrial ovens?
Yes, when the build suits the importing site: the electrical supply or the gas type and pressure, and the safety route for that region. The European Union and North America each follow their own oven standards, so confirm which applies before quoting, and ask the buyer early for the site's supply details and any inspection requirements.
Which industries buy industrial ovens?
Powder coating and paint shops buy them to cure finishes on parts. Foundries use convection ovens to dry the coating on moulds and cores. Welding and fabrication shops bake and hold welding electrodes in ovens. Composite part makers cure resin parts in batches, and other plants use ovens to age, bond or heat treat parts and to bake adhesive onto products.
I make industrial ovens. How do I find verified buyers?
diipl works out which kinds of buyer need your type of oven and in which regions, for example coating shops, foundries and composite makers, and contacts them. Before any meeting, diipl checks that the buyer has a real requirement, a funded plan, the authority to order and a date in view. Your name and contact details stay off the page. Bring a recorded heat-up and uniformity survey, your safety package and a list of wear spares to the meeting.
What is the difference between a batch oven and a conveyor oven?
A batch oven handles work in limited quantities, often loaded onto mobile racks, carts or trucks, and is also called a cabinet or walk-in oven. A conveyor oven is typically part of an automated conveyor line and allows higher volume processing. For a conveyor oven, ask the maker how line speed and the ramp-up time of your parts were used to size the oven.
Is infrared or convection better for curing powder coating?
Convection is by far the most common method and the simplest to operate, but it is the slowest and the least energy efficient, and it needs the most floor space. Infrared is faster: one trade source says catalytic infrared can cure in about a third of the time, and electric infrared up to 10 times as fast as convection. The same source says powder makers' cure times are greatly overstated for infrared, so test your own part.
How long should a part stay in the oven to cure powder coating?
The stated temperature is the part (metal) temperature, not the oven air temperature, so the oven must also give the part time to heat up. One supplier ladder for a polyester powder lists 7 minutes at 200 °C, 10 minutes at 193 °C and 14 minutes at 182 °C. Part temperature follows a bell-shaped curve over the cycle, so log the part itself rather than trusting a timer.
How is temperature uniformity checked in an industrial oven?
A profile test measures the temperature at several points inside the empty chamber while the oven runs under static conditions. One maker states a uniformity of plus or minus 5 °F at 285 °F, checked with a nine-point profile test in each empty chamber. Ask for the figure at your own working temperature, the number of test points and a copy of the test record.
