Suction Accumulators
With Electric Float
These accumulators have a built in electric float switch to provide a warning, or shut down the compressor in case
of a major flood back exceeding the holding capacity of the accumulator. Float switch contacts may be easily
replaced externally without disturbing the refrigerant charge.
Heat Exchanger-Suction Accumulator Combinations
For Ice Making Heat Pumps, A.C.E.S. Or Maximum Heat Transfer
These suction accumulators have been especially designed to provide a maximum amount of heat exchange
surface for use in special applications. It may eliminate the need for a separate heat exchanger.
