Operation of the heat pump online


Advances in technology allow full monitoring of heat pumps online. Through a remote connection room temperatures, water temperatures and operating parameters can be monitored and altered remotely. Data collected from the heat pump and stored, accessible for several years.

Continuous monitoring of the heat pump allows us to provide a 7-year warranty when connected to the Internet.

Very quiet operation thanks to the new design fans

We use only:

  • advanced low-speed fans with a very low sound level
  • quiet double scroll or rotary compressors, located in the indoor unit on a special anti-vibration frame
  • electronically controlled expansion valve, substantially reducing noisy "shock" when defrosting the outdoor unit
  • special soundproof cabinets

Desuperheater: high temperature DHW

  • An optional desuperheater device can be fitted to the heat pump to provide efficient high temperature domestic hot water heating. It is a heat exchanger energy consuming high temperature at the outlet of hot vapor from the compressor. This energy is transferred into a separate hydraulic hot water circuit. Hot water runs when the compressor is running as a "byproduct" to heat domestic hot water.

Inverter: experience the future, today

Alternating the frequency of an inverter heat pump allows continuous regulation of the heating / cooling capacity between 30-100%. It has a number of other advantages including:

  • Bigger energy savings
  • Increasing the overall COP
  • Reducing the number of starts, increasing lifespan
  • Zero amp starting current eliminating upgrades required to connect to electricity network
  • No requirement for buffer tank – saving cost and plant room space.

Intelligent control of heating circuits

Heat pump Master Therm = entire heating (cooling) system. Master Therm brings you the highest possible level of control of heating or cooling circuits. Control up to 6 heating circuits incl. swimming pool, solar array and DHW.

The heat pump receives requests for heating water temperature of individual heating circuits Revises its desired internal room temperature in individual heating zones. The heat pump provides heating temperature corresponding to the maximum desired value, is the currently hottest heating circuit, other circuits control the mixing valve.

The heat pump and never work with a higher flow temperature than is absolutely necessary. Similarly, when cooling. This is for all times to ensure maximum COP and the inside temperature is very accurately controlled.

Electronic expansion valve

Electronically controlled expansion valve (EEV) moves heat pump several classes higher. Increases its efficiency (COP), operational reliability and lifetime. Prioneering the use of electronic refrigerant injection. we are among the leaders in using this technology and it is constantly improving.

EEV allows to accurately control the temperature of the refrigerant on the evaporator. With EEV, we can provide additional heating capacity and increase the coefficient of performance (COP) of the heat pump.

EEV protects the compressor at high loads controlled by spraying liquid. Conversely, under low load (e.g. at a heating water flow temperature <30 ° C) can be an electronic valve is fully open, and to achieve a high COP, a thermostatic valve (TEV) is not possible.
