Bemco FB1.5V Environmental Chamber 1.5 Cu Ft -100 to 350°F Watlow 942 As-Is

Bemco FB1.5V Environmental Chamber 1.5 Cu Ft -100 to 350°F Watlow 942 As-Is

The Bemco FB1.5V is a mobile floor-standing environmental test chamber with a 1.5 cubic foot test compartment, designed for thermal testing across a wide temperature range of -100°F to +350°F. This unit includes a Watlow Series 942 digital temperature controller and a Thermotron Therm-Alarm over/under temperature alarm module mounted on top. It is being sold as-is for parts or repair — it has not been powered up or tested.

Applications

Environmental test chambers like the Bemco FB1.5V are used in electronics manufacturing, aerospace, defense, and materials testing to subject components and assemblies to controlled temperature extremes. A unit rated from -100°F to +350°F covers a broad thermal range suitable for both cold-soak and high-temperature bake testing — common in qualifying PCBs, sensors, mechanical assemblies, and packaged electronics to military and commercial reliability standards (MIL-STD, JEDEC, ASTM). The mobile, self-contained cabinet design with integrated refrigeration and heating made this type of Bemco chamber well suited for production floors and smaller test labs that needed thermal testing without a fixed installation. Bemco (formerly a brand under the Cincinnati Sub-Zero / associated manufacturing ecosystem) produced benchtop and floor-standing chambers through the 1980s and 1990s that remain in service and are sought for repair and parts to maintain older test fleets. A unit like this — with its compressor, copper coil, Watlow controller, and Thermotron alarm intact — has real parts value for shops maintaining similar Bemco chambers.
