More Heat. More Air. Less Money.

Reliant powder coating ovens include free start-up and calibration by our technicians. Through expert tuning, our ovens reach curing temperatures faster and cost less to operate. Our proprietary heat system, 6” thick insulated panels, and innovative air flow design save fuel, increase reliability, and help keep your oven at the ideal curing temperature. 

Reliant Finishing Systems builds ovens in hundreds of standard sizes and thousands of possible configurations. We offer oven models that are perfectly suited for powder coating applications of all sizes. Our modular designs make it easy to enlarge, relocate, or reconfigure your powder curing oven in the future.

An American-made powder coating batch oven or constant process oven from Reliant Finishing Systems will consistently provide the uniform, durable finishes you need. All Reliant ovens include a two-year warranty and free lifetime phone support.

A Powder Coating Oven is Built For Performance

From our proprietary heat systems to our 6” thick walls, 6” thick roofs, and 5” or thicker doors, our high-performance powder curing ovens are designed specifically for powder coating applications. For over 15 years, we’ve been researching, refining, and upgrading our equipment to provide both experienced coating specialists and first-time powder coaters with appliances that produce high-quality, long lasting powder finishes.

Finishing Equipment That Works

We use state-of-the-art burner technology to get the oven to curing temperature faster – which saves you time and money every day. Whether you need a stand-alone batch oven or a complete powder coating equipment package, our products are built with efficiency and durability in mind. We never compromise when it comes to quality, performance, or support after the sale.

Reliant ovens use less fuel to cure powder coated parts, which reduces your operating costs and improves your bottom line. Our standard models range from small walk-in ovens 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 up to 36’, widths up to 48’ 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, and conveyor or cart system integration. Color touchscreen controls with integrated data logging capabilities are another popular option. Custom burner and exhaust configurations are also available.

We offer pre-heat ovens for multi-coat applications, drying ovens for use after chemical pretreatment, powder curing ovens, and multi-function oven designs for all powder coating situations. We can build to client-specified dimensions and layouts.

Technical Specifications

Curing Oven Construction

We use only prime domestic steel. All walls, ceiling, ducts, and roof are made of 20 gauge or heavier G90 galvanized, aluminized, or stainless steel components. 

Reliant ovens utilize a double panel design that assures perfect installation results. The interior walls and roof are made from 6” deep panels that receive factory-supplied insulation. Mineral wool insulation of at least 6# density is inserted between these inner panels and the external skins during installation. Most oven enclosure components are bolted together, typically on 6” centers. No field welding is required. Although we recommend professional installation by our technicians, we also offer DIY kits for our most popular powder curing oven models.

Coating Ovens Doors & Frontals

The oven doors are typically 5” or thicker and house mineral wool insulation of not less than 6# density. Reliant doors feature a rigid internal steel frame and are designed so they don’t warp or sag 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.

Our standard oven doors keep heat in, but still provide smooth operation without the need for floor casters, locking latch rods, or frequent adjustment. 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 Systems

Our ovens’ heat systems are constructed of primarily 11 gauge, 16 gauge, and 18 gauge aluminized, G90 galvanized, or stainless steel components with mineral wool insulation of at least 6# density used throughout. Reliant heat systems utilize ETL-listed Power Flame “Jet Fire” forced-induction burners with integrated combustion air supply fans. They adjust “on the fly” in response to the control panel’s PID fuzzy logic controller or are controlled by a PLC device linked to a color touchscreen HMI.

The heat system’s enclosure includes a dual-inlet/dual-outlet forward curving fan wheel to cycle the heated air through the oven enclosure and the combustion chamber features a stainless steel blast tube and splash plate. Our curing oven heaters include oversize fan shafts for durability and reduced vibration, as well as special high-temperature bearing assemblies that are easily accessible. Each unit is optimized on-site by a Reliant technician for premium results at the customer’s location.

Controls

Reliant heat units and exhausts are controlled via a remote control panel in a NEMA enclosure. The standard 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 oven accordingly. Upgraded models typically include a color touchscreen HMI and custom-programmed PLC.

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.

Exhaust

A high-performance ventilation fan assembly is mounted to the shop floor using anti-vibration bushings. The assembly typically uses a belt driven backwards-inclined fan. The fan draws air from the area near the oven 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 (Type-B/Class-B) exhaust ducting with a high-flow exhaust cap.

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.

Delivery & Installation of Oven for Sale
