Freeze Thaw Chambers

Freeze Thaw Chambers

salient features

Labtop Programed Logic controlled (PLC ) Freeze thaw chambers are used for drug excursion testing, concrete and asphalt testing, coating and adhesive testing, outdoor weathering testing and extensively used in packaging and pharmaceutical industries, food and beverage industries , for testing and measuring the resistance of products deterioration caused by repeated cycles of freezing and thawing. Temperature range adjustable from -20.0°C to 60.0 °C .

cabinet construction

The cabinet of Labtop Freeze Thaw Chambers are insulated with high density CFC free Poly Urethane Foam. Interior of the chambers are mirror finish stainless Steel (304 SS, 1.0 mm thick). The exterior is white powder coated (1.0 mm thick) mild steel and the door has magnetic gasket with a keyed door lock. Specially designed solid stainless steel wire mesh trays ensure even temperature distribution and storage inside. GMP models are in total stainless steel (Inside S. S 304 with mirror finish and outside. S.S 304 dull finish and inner S.S316 is also available on request at extra cost )



A programmable logic controller (PLC) is a digital computer used for automation of controlling electromechanical processes, such as control of Temperature, Relative Humidity, Standby systems and event management with less maintenance hence no moving parts.
