5.1 Main components
Compressors
POWERCIAT2 units use accessible hermetic compact
screw compressors.
Oil
The oil contained in the compressor is used both for
lubrication and dynamic sealing of the space between
the rotors. Its solubility, viscosity and foam formation
characteristics therefore must be respected. Only use
recommended oil: Bitzer polyester (POE) BSE 170.
Refrigerant
POWERCIAT2 units use R134a.
Exchangers
The evaporators are shell and tube type exchangers.
They are insulated with 10 mm thick polyurethane foam
as standard. In its standard configuration, the shell and
tube exchanger is only designed to operate with clean,
non-corrosive fluids such as pure water, soft water,
monoethylene glycol or monopropylene glycol. Fluids
such as brackish water, seawater and demineralised water
require a specialised design. We recommend filtering the
energy transfer fluid.
No repairs or modifications are permitted on the evaporator.
Only replacement of the heat exchanger with another
original heat exchanger and by a qualified technician is
authorised. If the heat exchanger is replaced, this must be
noted in the maintenance booklet.
The maximum authorised pressure (PS) in the hydraulic
circuit is 10 bar.
Electronic expansion valve
Each unit is fitted with one-piece hermetically-sealed
electronic expansion valves that are set in the factory to
maintain superheat of 5-7°C under all operating conditions.
Filter dryer
Each unit is fitted as standard with a filter dryer to keep the
refrigerating circuit clean and free of moisture. The filter
dryers consist of a molecular sieve that neutralises any
acids in the refrigeration circuit.
Liquid sight glass
Located on the liquid line just after the filter dryer, the liquid
sight glass is used to monitor the charge in the unit and to
check for moisture in the circuit. Bubbles in the sight glass
mean that the refrigerant charge is insufficient or that non-
condensable gases are present in the refrigerating circuit.
If the sight glass indicator paper changes colour, there is
moisture in the circuit.
Some of the sight glasses may turn yellow when the
machine is powered off as their sensitivity is affected by
the fluid temperature. These should return to green after
the unit has been operating for a few hours. If the sight
glasses remain yellow, there is excessive moisture in the
circuit. A specialist intervention is required.
4.1 Data plate
Each POWERCIAT2 unit has a manufacturer's data plate
bearing the unit's identification number and description.
Make sure this information matches that on the order.
5. DESCRIPTION
Markings (data plate, punch marks, labels) must remain
visible. They must not be altered, removed or modified.
Please include the identification number in all
correspondence with CIAT.
