Thermal Product Solutions ships Gruenberg cleanroom ovens to medical industry


Thermal Product Solutions, a global manufacturer of thermal-processing equipment, announced the shipment of six Gruenberg cleanroom ovens to the medical industry.

These Gruenberg unitized ovens have a maximum temperature rating of 149°C with work chamber dimensions of 26” W x 26” D x 34” H. The Gruenberg cleanroom ovens were constructed from a structural steel frame that supported the 304L stainless steel interior chamber liners and the 304 #4 polished stainless-steel exterior. All interconnecting struts are non-continuous, which keeps the exterior cool.

The front-loaded cleanroom ovens used horizontal airflow, which maximizes heating rates and temperature uniformity of the product load. A circulation blower is located in a conditioning plenum chamber on the bottom of the oven. The blower directs air through a semi-pierced panel on one side of the chamber and flows horizontally across the product. The air exits the work chamber on the opposite wall back through the plenum for reheating and recirculation.
