BoxAir Inverter Split heat pump

Two-piece construction at a favorable price

The new BoxAir Inverter Split heat pump continues the very successful tradition of Master Therm split heat pumps. The original  concept with a compressor located in the indoor unit  brings a number of advantages. The most valuable components of the heat pump  are located in the engine room  and are protected against the external environment with a positive impact on service life and ease of installation and service. The connecting pipe between the indoor and outdoor unit forms a  low-pressure (cold)  part of the cooling circuit. This  fully eliminates heat loss through the piping and thus the distance between the units can be extended. The outdoor unit is compact and, due to the absence of a compressor, also extremely quiet, very light and vibration-free.

We will prepare a complete technical and price proposal for you free of charge and within 48 hours.

Save up to 70% on energy

There is no doubt that energy and fuel costs will rise at a similar pace in the future as in recent years. Any increase in energy prices will only marginally affect the operation of the heat pump.

The example on the right shows a comparison of the total energy costs for an average family house with a heat loss of 7 kW. Energies are calculated for a family of 4.

Thermal comfort at your fingertips

Keep the heat under control

All Master Therm heat pumps can be connected to the Internet. Each user then has the opportunity to monitor and control the heat pump from the web, tablet or mobile phone.  You have the heat of your home under full control and at your fingertips.

In addition, the heat pump is monitored around the clock and the heating data is evaluated automatically. This increases the heating efficiency and your thermal comfort even more over time.

technology regulation

Smart regulation

The heat pump never provides a higher heating water temperature than is absolutely necessary and works at maximum efficiency in all circumstances. In addition, the temperature of the interior is very precisely controlled.

Electronic expansion valve

The electronically controlled expansion valve (EEV) moves the heat pump up several classes. It increases its efficiency (heating factor), operational reliability and equipment life

Unique Feature Desuper

Desuperheater

Desuperheater is a device integrated in the heat pump, designed for efficient hot water heating. The desuperheater is the only one that allows hot water to be heated to a high temperature with a very high heating factor.

Inverter technology

By means of a control based on a frequency converter, the heat pump enables continuous regulation of the heating / cooling output in the range of approx. 30-100%. This has a number of other benefits.
