Powder Coating Ovens

Powder Coating Oven Buttons

More Heat. More Air. Less Money.

Reliant powder coating ovens reach curing temperatures faster and cost less to operate because our innovative air flow design keeps the oven interior evenly heated while saving fuel. With over 300 standard models, we have powder coating ovens that are perfectly suited to jobs of all sizes. Our modular oven design is unique among powder curing ovens on the market today. It allows you to easily reconfigure and fine tune your oven if you ever need to relocate it, plus you can easily expand the size in the future without wasting money! An American-made powder coating batch oven from Reliant Finishing Systems will consistently produce the uniform, durable finishes you need.

Powder Coating Oven Manufacturer

Powder Coating Oven is Built For Performance

From our proprietary heat system to our 5” or thicker doors, our powder curing ovens are designed specifically for powder coating. We have spent over 15 years researching, refining and updating our equipment to provide experienced coating specialists and first-time powder coaters with the appliances they need to produce high-quality, long lasting powder finishes. Our equipment is built with efficiency and durability in mind, using premium-quality components. We that never compromise when it comes to quality or performance.

You Deserve Equipment That Works – That’s All We Build

We use state-of-the-art burner technology that gets the air to curing temperature faster – which saves you time and money every day. Our powder coating equipment uses less fuel, which reduces your operating costs. Our 6″ roof and wall panels use bolt-together construction which makes for a more rigid and stable appliance. We use genuine Rockwool brand (delete, Rock Wool went out of business)  high-density mineral wool insulation that keeps the heat inside the coating oven cabin and out of your work space. No matter what oven design you choose, it will be heat efficient and built to create optimal airflow throughout the powder coating oven enclosure, preventing hot or cold spots and providing an even, consistent cure for your parts.

Oven Options

Standard sizes range from small walk-in units to large industrial curing ovens for coating heavy equipment. Standard batch oven sizes range from 6’H x 6’W interior working dimensions to 12’H x 12’W interior working dimensions, with standard lengths up to 50′. Custom ovens can be designed with heights of over 30’, widths of over 50’ and lengths of over 120’. We also offer conveyorized coating systems for manual or automated powder coating.

Popular options include custom frontals/doors, interior dividing doors for multi-zone curing, conveyor or cart system integration, custom push-button or color touchscreen controls, and integrated data logging systems. Custom burner and exhaust configurations are also available. All our powder coat (ok to leave as powder coat) ovens feature premium 6″ or thicker insulated wall and roof panels. We offer pre-heat, drying, curing, and multi-function oven designs, and can build to client-specified dimensions and layouts.

Technical Specifications

Curing Oven Construction

We use only prime domestic steel. The oven walls, ceiling, ducts and roof are made of 20 gauge or thicker G90 galvanized or aluminized steel components. The oven utilizes a double panel design that assures a perfect installation. The interior walls and roof are formed into 6” panels to receive factory-supplied insulation. Mineral wool insulation of at least 6# density is inserted between these inner panels and the external skins during installation. The main oven enclosure components are bolted together, typically on 6” centers. Threaded inserts in key parts help simplify assembly. When using roof mounted heat units or double load-in frontals, the ovens are equipped with support beams to increase rigidity. No field welding is required. Although we recommend professional installation by our factory-authorized technicians, we also offer DIY kits for most popular oven models.

Coating Ovens Doors & Frontals

Door thickness is included in the exterior dimensions cited for our ovens. The oven doors are typically a 5” or thicker composite design made of 11, 16, 18, and 20 gauge components that house mineral wool insulation of not less than 6# density. The doors feature a rigid internal steel frame and are designed so they don’t warp over time due to heat. Durable fiberglass and vermiculite gasket material is included. The doors have a snug fit against the supplied gasket, but are very easy to open and close. The doors keep heat in, but still give smooth, adjustment-free operation without the need for floor casters or locking latch rods. Friction latches, often known as “panic latches” or “slam latches,” enable the doors to be opened from the inside in an emergency, and they also serve to safely vent excessive positive pressure from the oven enclosure.

Coating Oven Heat Unit

The heat unit is constructed of primarily 11 gauge, 16 gauge and 18 gauge aluminized or G90 galvanized steel components with mineral wool insulation of at least 6# density used throughout the assembly. The heat system utilizes an ETL-listed Power Flame “Jet Fire” forced-induction burner with an integrated combustion air supply fan. The heat unit’s combustion chamber features a stainless steel blast tube and splash plate. The heat unit adjusts “on the fly” in response to the control panel’s PID fuzzy logic controller or is controlled by an advanced PLC device. The heat unit enclosure includes a dual-inlet/dual-outlet forward curving fan wheel to cycle the heated air through the oven enclosure. The heat unit features an oversize fan shaft for durability and reduced vibration, as well as special high-temperature bearing assemblies that are easily accessible. Each unit is optimized for premium results at the customer’s location and shipped with a fan performance graph.

coating controls


The heat unit and exhaust are controlled via a remote control panel in a NEMA enclosure. The control panel allows the operator to see a digital display of both the oven’s interior temperature and the heat unit’s output air temperature and adjust the unit accordingly. The control panel includes a variety of safety devices, including audible and visual alarms. The control system typically uses one or more variable frequency drives (VFDs) to adjust the atmosphere inside the oven by fine-tuning the performance of the exhaust system. Upgraded models may include a color touchscreen HMI and custom-programmed PLC.


A high-performance ventilation fan assembly is mounted on-site to the shop floor using anti-vibration bushings. The assembly typically uses a backwards-inclined fan mated to a motor drive via a belt system. The fan intake draws air from the area near the floor—exhausting only the coolest air from the oven. The exhaust drive components are housed in a ventilated steel enclosure and the exhaust system requires the use of double-wall (Class B) exhaust ducting with a high-flow exhaust cap that prevents the intrusion of water.

Outsourced Components

Exhaust duct, duct mounting adapters, combustion air supply fan intake duct (if required), gas piping to the oven’s heat system, regulator ventilation piping, electrical service connection to the control panel, and field wiring components are typically provided by other companies and are not included with our ovens.
