DOMESTICHOT WATERThe unit can also supply domestic hot water (option)by 3-way valve

Zeta Rev HP XT allows to cover the whole thermal load requirement of the system, ensuring the space heating/cooling and also the request of domestic hot water. Satisfying these needs by means of a single unit offers a simpler, cost-efficient solution.

ECAXIAL FANSEC axial fans with electronically commutated brushless motor as option.

15% energy saving per fan

2.000* € /y saving(*unit with 8 fans; operating 8700 hours/year; 0,10 €/kWh)

SMARTANTI-ICECIRCUITThe defrost cycle can be a critical condition: ZETA REV HP XT features the Smart Anti-Ice Circuit, to avoid ice forming on the bottom part of exchanger: the function is efficiently activated according to air temperature - only when necessary.

VAPOUR• Injection technology allows

heat pumps to withstand more extreme conditions than with conventional units.

• Lower air temperatures are reached, enhancing the use of heat pumps in cold climates.

•Hotter water can be obtained: reliable, flexible adoption in comfort systems with high temperature distribution – be-sides the supply of tap water.

• ZETA REV HP XT with VAPOUR INJECTION stretches further the combination of low air / high water temperatures, compared to simpler liquid injection.

•Vapour injection improves en-ergy efficiency too: at extreme conditions it grants the best COP, for real savings.

Two scroll compressors per

circuit.They are fitted to

the vapour injection circuit via dedicated

ports.

The injection circuitincludes the

economizer and the electronic expansion

valve, all managed by advanced control

algorithms.
