Infrared Ovens and HeatersWhether curing paint or powder, drying inks, processing plastics, or baking bread, Thermazone can help with the process. Infrared ovens, utilizing the Black Body emitter, transform nearly 90 percent of consumed energy into useful heat. The high temperature aluminized steel housing and stainless steel protective grid equip the heater to operate effectively in the harshest industrial environments. Systems are offered in more than 50 standard oven configurations with optional conveyors, exhaust blowers and vestibules or unusual applications. Custom-designed ovens can be manufactured to meet exact process requirements.
Ovens for Many ApplicationsCompany offers range of industrial ovens, including continuous models custom-designed for the specific application. The gas-fired drive-shaft tempering oven shown achieved a uniformity of +/-2°F at 450°F (232°C). The parts were conveyed through the oven on a custom-designed part holder riding on a two-chain conveyor. Other heat-processing equipment can be used for metal finishing, preheating, solder reflow, composite curing, drying, aging, sterilizing and shrink-fitting. Equipment can be heated by gas (direct and indirect), electric and steam with temperature ratings to 1,400°F (760°C).
Custom Ovens and DryersDesigned to utilize specific combinations of radiant and air-impingement systems to satisfy the user's process requirements, custom ovens and dryers ensure product uniformity and maximize production. Suited for use in chemical, food, finishing, plastics and rubber, and textile operations, the ovens and dryers range in size from high volume to small batch or lab prototype.
Ovens and Dryers Provide Uniform CuringThermatrol electric, gas or propane conveyor ovens utilize infrared heaters, infra-air, or combination infrared/convection heating so specific process needs are met. Other features include inline integral coolers, ability to interface with external PLCs, and integration with robotic operations. The infrared heat panels provide uniform curing and/or drying over the entire process. Recirculating hot air using high-velocity air knives breaks up moisture barriers and drives solvents away from the substrate.

Infrared Oven with Refractory Reflector Handles High TemperaturesBT Series uses a refractory board reflector that can withstand a much higher temperature than a metallic reflector. The unit does not require air or water cooling and is designed to operate continuously in a high temperature environment. Because cooling is not required, airflow does not contaminate the product and the system has a smaller profile. The infrared heater can be used as a stand-alone oven, or it can be designed as a booster to augment an existing process. Because of its design, it also can be mounted inside a convection oven.
Infrared Can Be Combined With ConvectionCompany offers a range of infrared equipment in many sizes and configurations. Infrared technology allows faster heating than convection ovens, decreasing oven floor-space requirements by 75 percent to 90 percent. Heating can be provided by either gas catalytic or electric infrared, in long, medium or short wave, and they can be combined with convection as necessary.

Paddle Unit Delumps and Conveys While DryingRosinaire consists of a horizontal, cylindrical vessel containing a longitudinal rotor/paddle assembly. The vessel body is fabricated with external jacket sections through which flows the heat transfer fluid (steam, hot water, hot oil, or chilled water). Radial paddles are fastened to the rotor shaft by means of locknuts. The adjustable paddle orientation determines the residence time of the solids within the vessel. Feed material is either pumped or conveyed into the high-speed, thin-layer, indirect-contact, paddle processor. The centrifugal action of the rotor/paddle assembly delumps and conveys the product material through processor as a thin layer of solids in a helical flowpath along the jacketed wall, resulting in heat transfer coefficients up to 150 BTU/hr/ft2/°F.
Custom Ovens Have Multiple Heating ZonesConveyor, batch/walk-in, laboratory and specialty ovens can be specified in temperatures up to 2,000°F (1,093°C).
