30 x 30. 36. 3. 4. Bemco FSV Series Vertical Thermal Shock chambers are available in two zone (FS2V - hot and cold) and three zone (FS3V hot - cold - hot) versions, with two temperature ranges (-75 C to +200 C or -160 C to +200 C), and two types of cooling systems (all mechanical cooling - no expendable refrigerant required, or all LN2).
A simple rule of thumb for relatively cool climates such as the Northeastern United States: one ton per 400 sq .ft. (Commercial) or one ton per 500 to 1000 sq .ft. (Residential) Or we estimate an air conditioning requirement of one ton per 400 to 800 sq .ft. for Space Pak Systems. Or a 3000 sq .ft. house may require a 5-ton unit.
