Low noise units using Maneurop compressors
January 2005
Fitted with Maneurop hermetic compressors, this new range of low
noise condensing units for refrigeration applications are manufactured
by J. E. Hall International.
The range is divided into five medium temperature units, and four
low temperature units, all for use with R404A and suitable for outdoor
installation. Evaporating temperature ranges are from 0C to -30C
for the 'M' models, and -20C to -45C for the 'L' models, with duties
ranging from 2,463 watts to 9,930 watts at -10C evaporating, and
1,826 to 5,706 watts at -25C evaporating. The medium temperature
models are also suitable for use on R134a or R407c.
As befits a unit that uses a Maneurop compressor, top quality components
are used throughout, the comprehensive specification including an
electronic fan speed controller, mains electrical isolator, compressor
contactor, IP55 rated control panel, crankcase heater, HP/LP pressure
switch, filter drier, sightglass, non-return valve, pressure relief
valve, rotalok valves, Gomax hose and an oil separator on low temperature
models.
Acoustically lined and with the suction gas cooled compressor further
insulated by an acoustic jacket, the units achieve noise levels
ranging from 33.8 to 35.5 dB(A) at 10 metres in Free Field conditions
