Thermal Product Solutions has shipped a Gruenberg explosion-resistant, friction-heated cabinet oven to the defense industry. The oven will be used to dry molding powders.
Thermal Product Solutions is a global manufacturer of thermal-processing equipment.
The operating temperature of this oven is 65ºC while the maximum temperature is 82ºC. The chamber’s interior dimensions are 25” W x 25” D x 25” H, and it is made from stainless steel 304 L. The oven has 4-inch thick, mineral wool insulated walls to minimize heat loss. The construction of the chamber uses a structural steel frame with interconnecting struts that are non-continuous from inner to outer walls, thus keeping the exterior cool.
The oven meets explosion-resistant requirements that are rated for operation in an XP Class I Div. I Group D and Class II Div. I Groups E, F, and G Environment. The interior of the oven is designed to be intrinsically safe with spark-resistant blowers, which minimizes the risk of any ignition sources.
“To ensure uniform heat distribution through the oven, we installed a high-volume and efficient 500 CFM horizontal airflow system. The friction fan and recirculation blowers are designed to be non-sparking in order to prevent them from igniting any flammable solvents that may be in the oven,” said Jonathan Young, Gruenberg, product manager
Features of this Gruenberg cabinet oven include:
- Fully welded liner.
- Double wall construction door hung on heavy-duty industrial hinges.
- Stainless steel blower wheels.
- XP external components including circulation motors, air flow switches, and wiring.
- Watlow PM controller.
- Intrinsically safe interior.
