The table below describes the main components of the refrigeration circuit.
1 Water outlet The water outlet piping connection is delivered with a victaulic
joint but without a counter pipe.
2 Evaporator The water-heat exchanger is of the brazed plate-heat
exchanger type.
3 Water inlet The water inlet piping connection is delivered with a victaulic
joint but without a counter pipe.
4 Compressor A hermetically sealed scroll compressor
5 Suction stop valve
(optional)
This suction stop valve can be used in combination with the
discharge stop valve to separate the compressors from the
system.
6 Discharge stop valve
(optional)
This discharge stop valve is used during pump down and
service work in combination with the liquid stop valve or suction
stop valve if present (optional).
7 Refrigerant circuit
safety valve
The safety valve prevents a too high pressure. Activation above
45 bar.
8 Drier/ charge valve The replaceable filter drier will keep the refrigerant system dry. It
is installed behind the condenser and removes small particles
from the refrigerant to prevent damage to the compressor and
the expansion valve. It is equipped with a 3/8” charge valve.
9 Liquid stop valve
(optional)
The liquid stop valve is used as a shut-off valve in case of a
pump down.
10 Oil sight glass An oil sight glass is placed in the compressor to check the oil
level of the compressor during operation.
11 Electronic expansion
valve + sight glass with
moisture indication
The electronic expansion valve is set up to control the
superheat between minimum and maximum setpoint. A sight
glass with moisture indication is integrated in the expansion
valve body and is used to check the refrigerant shortage and/or
moisture level in the system.
12 Check valve Service port.
13 Condenser The air-heat exchanger is of the cross fin coil type. Hi-X-tubes
and PE coated waffle louvre fins are used. The air is discharged
upwards.
14 Ambient temperature
sensor
The ambient temperature senor is used to measure the
temperature in order to perform some controls.
15 Fan Direct driven single speed fan or inverter driver fan (only OPIF)
16 High pressure sensor The high pressure transmitter is used to gain information in
order to perform some controls and also to act as safety.
17 Low pressure sensor The low pressure transmitter is used to gain information in order
to perform some controls and also to act as safety.
