Air to water series

Units with V type heat exchanger: panels, frame and base are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.

3-phase scroll type compressor, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.

External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.

Evaporator built with high efficiency shell and tube type heat exchanger, factory insulated with flexible close cell material. 

Condenser built with seamless copper tubes mechanically expanded into blue hydrophilic aluminum fins.

Refrigerant circuit complete with charge valves, filter drier, sight glass, gas-liquid separator, thermostatic expansion valve, high & low pressure switch. The heat pump unit is completed also with 4-way valve, liquid receiver and one way valve.

Hydraulic circuit built with galvanized pipe, complete with water discharge connection for tube in tube heat exchanger and flange type hydraulic connectors in two directions easy for connections from both sides of the units.

Electric panel consist of: 

compressor contactor, fan motor contactor, compressor protection breaker, fan protection breaker, phase sequence relay and microprocessor with function display (display only for master/packaged unit)

Automatic operation dramatically reducing maintenance cost thanks to reliable microprocessor system. 

Optional

Paddle flow switch;

Metallic filter for hydraulic circuit;

Water pump;

Rubber antivibration mounting.

Heat recovery functions

Water to water series

Going about as multi-function unit, for example, cooling, heating, sanitary hot water separately or at the same time. 

Wide application as hotel, apartment, villa, factory, shopping center, office building, school, etc. 

Semi-hermetic screw compressor for the whole range. Each compressor is outfitted with a crankcase heater and a built-in electronic insurance with temperature sensor located directly in the motor winding and on the discharge line. 

The refrigerant circuit is complete with sight glass, filter drier, high and low pressure gauges, solenoid valve, electronic expansion valve, high and low pressure switch. 

Shell and tube dry extension type condenser, production line protected with adaptable close cell material. 

Shell and tube evaporator, higher efficiency less water consumption, simple maintenance and cleaning, production line insulated with adaptable close cell material. 

The electric board comprises of compressor breaker, compressor contactor, phase sequence relay, control circuit breaker, microprocessor control with function display. 

LCD display, touch screen control board as standard. 

Programmed activity significantly decreasing upkeep cost because of reliable microprocessor system. 

A limitlessly factor limit control framework that is able to do precisely coordinating the interest prerequisite of the system is to be provided. This framework is to give exact and stable control of flexibly water temperature over the complete scope of working conditions. 

Optional 

Desuperheater as optional. 

Electronic controller with BMS system.
