Gas Batch Ovens

Gas Batch OvenRapid Engineering knows that in many industries time means money, which is why we've designed our Gas Batch Ovens to not only reach the high temperatures needed, but to reach them quickly and safely.

Our Gas Batch Ovens offer versatility through custom design, size, and variable heat settings - from 150 to 500 degrees - and can reach those temperatures in 30 minutes or less.

Rapid Engineering offers both standard and custom built Gas Batch Ovens in a variety of sizes. The only medium and large batch ovens we offer are gas fired. We do this in order to make operating these larger ovens more cost efficient. Heating a medium to large batch oven by natural gas or propane is usually more efficient than heating by electricity because large electric ovens require immense amounts of kilowatt-hours (kWh), which can become very costly and can present power availability issues. We do offer electric ovens, but they are smaller in size and only come in three standard designs. For more information on these smaller ovens, please visit Rapid Engineering's Electric Batch Ovens page.

When installed, used and maintained properly, Rapid Engineering's Gas Batch Ovens have great operational dependency and offer better oven balance, cleanliness and space usage from their unique duct design.

They are made out of high quality components, such as 6-inch thick aluminized steel insulated panel walls and ceiling, which translate into lower operational costs due to the energy-efficient, direct fire burners. These burners have a turndown ration of 20 to 1.


These Gas Batch Ovens can be used in several applications:

  • Preheating - Prepare various metals, plastics, wood, medium density fiberboard or other substrates for the coating or adhesive process.
  • Drying - Help eliminate water or moisture accumulated during the pre-treatment washing process.
  • Curing - Help elevate the part and coating temperature to achieve the desired coating cure characteristics.
  • Low Temperature Stress Relieving - Used to reduce internal residual stresses in a metal object by heating the object to a suitable temperature and holding at the temperature for a proper amount of time.
  • Out Gassing - Used to slowly release gas that was trapped, frozen or absorbed in some material.

The Gas Batch Ovens come in standard or customized sizes and include automatic shutdown, FM insurance-approved controls, digital temperature controls, flame safety controls, top mounted burner boxes, power exhaust and automatic purge timers, burner and high temperature limit controls, UL listed electrical control panels, ceiling-mounted ductwork distribution and double doors on one end. They are also designed and built to various industry standards.

The ovens are all direct fired convection ovens and are available in either natural gas or propane.

Other options include:

  1. 20 gauge aluminized, .25 steel plate, 3-inch insulated floor
  2. End or side mounted burner boxes
  3. Double doors on both ends
  4. Chart recorders
  5. Door-activated low-fire switches
  6. 120/220 VAC, 1 Phase, 60Hz
  7. 208/240 VAC, 3 Phase, 60 Hz
  8. Batch timers
  9. PLC Controllers
  10. Installation and startup by Rapid Engineering

"Install It Yourself" kit

We also offer low installation costs with our "Install It Yourself" kit. The kit is a complete assembly package that includes a burner box and manifold, an oven enclosure, door(s), an electrical control panel, and a powered exhaust fan. Installation, start-up and operating instructions are included.

Whether it's replacing an old oven in an existing system or designing a brand new system, Rapid Engineering can customize its Gas Batch Ovens to suit your specific needs and cost expectations. For more information or to speak to a Rapid Engineering expert directly, please contact us.
