i-MAX  66kW - 115kW

Air/water reversible inverter heat pump with axial fans

TECHNICAL CHARACTERISTICS
The i-MAX series reverse cycle heat pumps are designed for applications in commercial and industrial sectors, are most versatile and can operate in heat pump mode with the possibility of producing hot water at a temperature up to 60°C for environmental heating and/or domestic uses. The use of scroll compressors technology, specifically designed for R410A, matched with an INVERTER DC brushless motor compressor; the fans are driven by inverter DC motors, as well as the integrated circulators with variable water flow and the electronic expansion valve together optimize the energy consumption and the operational efficiency of the whole system.

FAN
The type of the fan is axial-flow with aluminium aerofoil blades of fibre. It is statically and dynamically balanced and supplied with fan grill for protection and locking). The electric fan motor used in this series is modulated by inverter, directly coupled and equipped with integrated thermal protection. The protection class of the motors is IP X4 according to CEI EN 60335-2-80 Rule.

USER SIDE HEAT EXCHANGER
The employed user side heat exchanger is made up of AISI 316 stainless steel braze-welded plates type integrating a dual cooling circuit. The user heat exchanger is factory insulated with flexible close cell material and can be equipped with antifreeze heater (KA optional accessory). The evaporator is provided with an immersion temperature sensor, used for antifreeze protection which activates the circulator, even in the case when the unit is in off mode and when the parameters adjusted by the controller have been occurred.

REFRIGERANT CIRCUIT
The refrigerant circuit has been manufactured by means of international primary brands components and according to the UNI EN 13134 Rule concerning welding procedures. The refrigerant gas is R410A. Each refrigerant circuit includes 4 way reverse cycle valve, electronic expansion valve, liquid separator, liquid receivers, auxiliary circuit to reduce the defrosting time, oil recovery circuit, non-return valves, valves of inspection for maintenance and control, safety device (high pressure switch) according to PED regulation, pressure transducers, precision sensors, high capacity filter dryer, mechanical filters.
