J & E Hall Packaged Condensing Units J & E Hall air cooled condensing units use HalIScrew single screw compressors with up to l64kW (220HP) of installed power and a wide range of cooling capacities. These factory built condensing units are easy to install and include oil separator, liquid receiver and filter drier. They are fully wired with all motor starters and controls and only the mains electrical supply and start-stop signal wiring is required on site. The units offer great value for money and are a cost effective alternative to site installed systems. The units are also easy to maintain. External oil filters can be replaced without opening the compressors. Isolating and drain valves allow the filter cartridge to be changed within minutes. Standard features Optional Inverter technology World famous HallScrew single screw compressor Vertical oil separator Air cooled condenser Condensing pressure control Large liquid receiver with dual safety pressure relief valves Filter drier and liquid sight glass Suction and delivery isolating valves and high pressure safety cut outs Pressure transducers for LP and oil pressure cut out Starter and control panel (suction pressure control) incorporating electronic controller suitable for remote monitoring via modem or GSM supervision system Available for use with R404a, R507a, R407C an R134a refrigerant With a small footprint the units can be installed where there isn't space available to install a plant room All equipment is IP54 rated Variable condenser fan speed Economiser (sub cooler) Option to buy single compressor units (no standby) Low noise unit with sound pressure level 80 dB(A) at lmetre.
