An ignition-free, patent-pending heating method is the basis a new oven from Gruenberg, a brand of Thermal Product Solutions. The Hurricane heating method is independent of the blower used for the circulation airflow, making it safe for use with volatile materials and solvents. The heating method utilizes two blowers: one blower circulates the airflow in the oven while the other blower generates heat from air friction created by the fan.

The oven is suited for use in Class I and II Hazardous Locations, where a range of flammable organic and inorganic materials are encountered in drying, curing, bonding, encapsulating and finishing applications. Because the systems are ignition-free, the maximum quantity of solvent per batch is not limited as it would be with a Class A oven. The modulated rotational speed for the heating blower adjusts the heat input without changing air circulation rate.
