FEATURES

STRUCTURE

The master module can work independently or together with up to 11 slave modules, cooling capacity from 150 to 1180kW.

HERMETIC COMPRESSOR

3-phase Semi-hermetic screw compressor, with built-in thermal overload cut-out , mounted on rubber vibration dampers.

AXIAL FAN

External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP55,F class provided with a protective outlet grille.

EVAPORATOR

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

CONDENSER

Condenser built with seamless internal screw thread copper tubes mechanically expanded into blue wave hydrophilic aluminum fins.

HEAT RECOVERY

The user needs to be able to realize the full 0-100% condensing heat recovery and recycling too cool heating

HYDRAULIC CIRCUIT

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

ELECTRIC PANEL

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.
