The benchtop chamber cannot fit the whole machine for -80C deep cold? Walk-in programmable high-low temperature room of 5 cubic metres reaches -80C within 80 minutes

The problem

Whole machines and large products cannot fit into benchtop chambers for -80C deep cold and thermal cycling; moving samples between separate low- and high-temperature chambers wastes time and adds error; missing -80C or exceeding fluctuation limits invalidates third-party data; and without a large window the chamber must be opened just to check the sample.

Capability

Walk-in chamber for reliability testing with human access; low-temperature room -80C (adjustable) and high-temperature room RT to +200C as two independent chambers with integrated control; internal volume about 5 cubic metres (approx. 5000x1000x1000mm) in split sections for transport and on-site assembly; temperature fluctuation and uniformity within plus/minus 2C; ambient to -80C within 80 minutes and to +200C within 60 minutes unloaded; load capacity 100kg per cubic metre; test time 1-999.59h settable; 400x600mm full-glass observation window with lighting; Tecumseh fully sealed 12HP compressor, green refrigerant, air-cooled condenser, finned evaporator with automatic load adjustment and imported expansion valve, solenoid valve and oil separator; custom blower motor with extended shaft and multi-wing impeller; self-developed touch-screen PLC control with PT100 sensor; SUS304 shell and thickened interior, rigid polyurethane foam plus glass-wool insulation; over-temperature protector, circuit breakers, thermal relays and high-pressure switch; AC380V/35kW at 50/60Hz.
