Solvent Venting Class A Oven

Gruenberg Solvent Venting Class A Oven

Product details

All standard Gruenberg ovens can be designed to house volatile atmospheres. Thermal Product Solutions designs all Class A ovens to conform to OSHA, NFPA 86A, Factory Mutual (FM) and Factory Insurance Association (FIA) requirements. As part of the safety design, Class A ovens must be equipped with a high exhaust rate: because the heating elements are an ignition source, a high exhaust rate is needed to dilute the volatile vapors below the “lower explosive limits.” As a result, the heating elements’ kW must be sufficiently increased to compensate for the heat loss caused by the above-normal exhaust rate. In addition, for a Class A oven to be energy efficient, the additional kW required must be carefully calculated according to solvent load and operating temperature requirements.
