The HYDRA heat pump units are particularly suitable for applications using radiant panel heating systems or low temperature applications such as suitably dimensioned fan-coil, thermal ventilation and AHUs for delivery temperatures of 50°C. All versions are fitted with noiseless EC axial fans and with Twin Rotary inverter compressors that allow complete power management of each individual component. In fact, the compressor, fan and circulators are continuously regulated by a programmed control unit with an internally developed control logic. It has been designed to be intuitive immediately usable; this allows the unit to be inserted into a large number of system configurations.

The 2-pipe units can control a high and low temperature circuit simultaneously.This solution allows the unit, via a hot water probe to control the temperature inside a domestic hot water storage tank (probe in the DHW storage tank) and to control a 3-way valve. The production of domestic hot water always has priority. 

The heat pump normally operates to meet the heating comfort requirements of the building, but when the temperature of the water in the tank falls below a set threshold, the control unit produces domestic hot water: if the unit is operating as a heat pump for heating the building, the 3-way valve will be switched and the set point will be modified; if the unit is producing chilled water for air conditioning, the control unit switches the unit into heat pump mode, assigns it the set point for the domestic hot water (which is normally higher than the system set point) and the 3-way valve is piloted to reach the appropriate position.

Once the water in the domestic hot water tank has reached the set temperature, the unit automatically reverts to producing water for the heating and air conditioning system.

Technical specifications

Split air-water heat pump: the outdoor unit is equipped with an EC axial fan and BLDC Twin Rotary Inverter compressor, and features a cutting-edge design and high COP.

The heat source is the outside air down to a minimum of - 20°C. Low noise is guaranteed by an intelligent control system that regulates the speed of the compressor and fan according to actual requirements. In addition, the use of anti-vibration mountings for the compressor and multi-layer noise insulation on the casing mean that noise is reduced to a minimum.

Cooling circuit

The refrigerant gas used is R410a. Cooling circuit with very high efficiency twin rotary inverter compressor. Pressure transducers and safety pressure switch. Stainless steel plate desuperheating exchanger and plate heat exchanger for evaporation / condensation. Copper-aluminium finned pack evaporator with special hydrophilic treated finning.

Dual defrost system by way of hot gas injection and/or reverse cycle.

Heat exchangers

The source side heat exchangers are made of copper pipes and aluminium fins coated with hydrophilic paint that encourages water run-off. The user side braze-welded stainless steel plate exchanger allows the amount of refrigerant gas to be reduced to the minimum and maximise the efficiency due to the large heat exchange surface.

Fan

The brushless EC axial fan has been designed to reduce noise to a minimum and to maximise efficiency. The speed of rotation is continuously regulated by the control unit.

Control and protection

Evco electronic control with integrated inverter compressor control, pump and fan modulation. Climate logic management. Standard ModBUS communication protocol.
The unit is equipped with a series of alarms designed to protect it from faults. These are managed entirely by the control unit that makes them available and accessible. It is also possible to access the controller via the control unit if you need to make any adjustments.

V-Color remote controller (optional)

The control unit consists of Evco hardware and can be combined with a highly intuitive touch-screen controller with which all the operating parameters, set points and usage settings can be controlled. The controller allows direct connection to the heating system with or without a storage tank, or more commonly, by connecting the latter to the heating system at two or four points. The storage tank is charged at a set point for DHW and with a heating or cooling curve for heating / cooling circuit.

Testing

All units are fully assembled and wired. They are inspected to high standards, undergo leak and vacuum cycle tests, and are filled with an eco-friendly refrigerant. They undergo a complete functional test before being delivered. All units comply with European Directives and have a CE marking and relative certificate of conformity.
