BWT Zubadan Range

We are proud to offer the new BWT Zubadan range of swimming pool heat pumps

The BWT range have been delveloped in conjunction with Mitsubishi - a leading manufacturer of heat pumps for homes and the domestic market

This exciting product brings together the excellent low temperature performance of a Mitsubishi heat pump with a built in swimming pool heat exchanger.

The result is one of the best performing swimming pool heat pumps on the market

Climexel heat pumps are fully inverter driven

They provide high output at low air temperatures and so are ideal for indoor pools as well as outdoor pools

The BWT Zubadan technology allows these heat pumps to work down to -25c !



We have the following BWT Zubadan Inverter models available:-

Model Max Pool Size (m3)
MZI 160M (26kW - Single Phase) 104 m3
MZI 190M (31.4kW - Single Phase)  123 m3
MZI 190T (31.4kW - 3 Phase) 123 m3
MZI 320T (50kW 3-Phase) 208 m3

** : The values indicated are valid under ideal conditions: Ambient air temperature 15°C. Water temperature 26°C. Pool covered with an isothermal cover at

Inverter Driven

BWT heat pumps are fitted with a frequency variator capable of adjusting the compressor and fan speeds.
On the contrary to the compressor and fan(s) in conventional On/Off heat pumps that run at a fixed speed (50 Hz), those in the Climexel heat pumps run at variable speeds (11 to 100 Hz), thus allowing the machine to automatically adapt to the heating demand and climatic conditions.
While the outdoor temperature is low, or while the heating demand is high, the Power Inverter® compressor and fan(s) run at high speed, between 50 Hz and 100 Hz).
Inversely, while the heating demand is low, or while the heat pump is running at temperatures around the set point, the Inverter® compressor and fan(s) will run at low speeds (between 11 Hz and 50 Hz).
At low speeds, BWT heat pumps’ COP is improved by 30 to 40 %. Running at low speeds, the Inverter® compressor and fan(s) are almost noiseless and provide optimal yields. In addition, the service life of the Climexel heat pump compressor, and other components, is extended.
