The use of inverter technology in conjunction with DC brushless motors ensures extremely high global energy efficiency, both by reducing the specific consumption of each motor and through high modulation capacity. The extensive application of these technologies to all components results in high COP and EER values, with a consistent increase in efficiency at partial loads
Main Features

Models from 5 to 16 kW

Control system with microcontroller regulation and superheat control logic via an electronic expansion valve.

Operation with eco-friendly R32 gas.

Compressors: Twin Rotary DC inverter.

Fans: Axial type with DC brushless motor.

Source exchanger: Optimized circuitry consisting of a finned coil with copper pipes and aluminum fins with hydrophilic treatment.

User exchanger: AISI 304 stainless steel brazed plate heat exchanger with low pressure drop on the water side.

Refrigerant circuit: Manufactured in copper tubing, including: condensation control, electronic thermostatic valve, reversing valve, high/low pressure switches, liquid separator and receiver, maintenance and control valves, double pressure intake, and high/low pressure transducers.

Integrated hydraulic circuit: High-efficiency variable-speed brushless circulator, expansion tank, flow switch, air vent valve, overpressure valve (3 bar), pressure gauge, and system filling/drainage tap.

All units can operate in 3 different modes: heating, cooling, and domestic hot water (DHW), with specific programming to optimize performance in all conditions, including potential thermoregulation based on the climatic curve.

The units are capable of managing diverter valves and secondary circuit pumps. Additionally, they can control the solar thermal system, potential integration with external heat sources, and interfacing with external Smart Home (Domotics) systems.

The Unitec 2 series can be remotely controlled via Wi-Fi by accessing the system directly through a dedicated App.
