Description

Construction features

• Compressor: high energy efficiency semi-hermetic screw driven by fixed speed motor with linear capacity control and/or variable Vi regulated by inverter (25-100% single-compressor sizes, 12.5-100% bi-compressor sizes), limited start, complete with integral protection, casing heater, oil level sensor and shut-off valves on delivery and intake piping.
• Water side heat exchanger (evaporator): low refrigerant charge spray flooded type shell and tube exchanger, complete with closed cell polyurethane foam rubber insulation, water flow differential pressure switch and Victaulic fittings.
• Water side heat exchanger (condenser): tube and shell complete with safety valve, service valve on the high-pressure refrigerant gas circuit, and a water flow differential pressure switch and Victaulic fittings.
• Control: microprocessor electronic control.
• Structure: made of galvanised and painted steel plate with polyester powder coating.
• The unit is also complete with:
- clock board;
- electronic expansion valve;
- display of cooling circuit high/low pressure;
- Master/Slave control up to 4 units in parallel;
- 0-10V analogue signal for condensing control from external device;
- control of Variable Primary Flow (VPF_R).
