Description
Aircooled Liquid Chiller with axial fans for outdoor installation.
Frame
Self-supporting galvanized steel frame further protected with polyester powder painting. Easy to remove panels allow access to the inside of the unit for maintenance and other necessary operations.
Compressors
Scroll with oil sight glass. They are fitted with internal overheat protection and crankcase heater. They are installed on rubber shock absorbers.
Fans
Axial Fans directly coupled to a three-phase electric motor with external rotor. A safety fan guard is fitted on the air flow discharge.
Condenser
Made up of two finned coils with copper pipes and aluminium fins. Circuits are made to create two independent circuits.
Evaporator
AISI 316 stainless steel braze welded plate type, with two independent circuits on the refrigerant side and one on the water side.
Electrical Board
It includes: main switch with door safety interlock, fuses, thermal protection relays for compressors, thermocontacts for fans, interface relays, electrical terminals for external connections.
Microprocessor
For automatic control of the unit, allowing continuous display of the operational status of the unit, control set and real water temperature and in case of partial or total block of the unit, indication of security device that intervened.
Refrigerant Circuit
Each unit includes two independent refrigerant circuits. Made of copper pipe, it includes the following components on all models: electronic thermostatic expansion valve, cooling circuit shut-off valve on liquid line, filter drier, liquid and humidity indicator, high and low pressure switch (with fixed setting), safety valve.
Water Circuit
It includes: evaporator, temperature sensor, antifreeze sensor, water differential pressure switch, manual air vent.
