Associated
Environmental Systems SD and FD Series Mechanical Refrigeration Chambers
offer a wide variety of bench top and floor model testing equipment
for simulating low temperature environments.
The
refrigeration system of these test chambers are either conventional
single stage systems or two stage cascade systems. All of the chambers
are designed to satisfy both military and commercial requirements standard
to industries performing low temperature test programs.
The
single stage unit consists of a single compressor and single refrigerant.
Associated uses a single stage system on all of our standard and custom
designed chambers requiring a low temperature limit of -35°F/-37°C.
The
two stage cascade system, as its name implies, cascades the refrigeration
effect of the high temperature stage to extract heat from the low temperature
stage. The cascade system consists of two separate closed refrigerant
circuits, each using a different refrigerant, each with its own compressor.
This type of refrigeration system is used on all standard and custom
chambers requiring a controlled low temperature limit of -100°F/-73°C.
