Heat pump Inverter with indoor wall unit

Description

Air Inverter II - B is the new heat pump with wall installable for heating, cooling and DHW production.

It is composed of an external unit with very high efficiency and a small box for the interior. Air Inverter II - B can be installed on the wall and in any building minimizing space and optimizing architectural integration building.

Available in 7 sizes from 4kW to 16kW with single-phase and three-phase power supply. It works with wide operating limits from -20 ° C to external 46 ° C and with flow temperature up to 60 ° C.

It is suitable both in new buildings and in the event of energy requalification in single or multi-family residential areas.

The compact heat pump

The Air Inverter II - B heat pump consists of two sections:

An internal unit of compact dimensions, which can be fixed to the wall, designed for direct connection to a sanitary storage tank.
The silent outdoor unit with extremely small dimensions.

The advantage of the heat pump is its small size, it can be easily installed instead of the old wall-mounted boiler or in the kitchen cupboards.

Internal unit structure

1) Load-bearing structure in highly resistant sheet metal
2) Hydronic module
3) Supplementary electric heater from 2-4 kW and 6 kW (optional)
4) 3 valve through pre-wired sanitary management
5) 3 bar safety valve with pressure gauge
6) Condensate collection tray

The heat pump is easy to install

Air Inverter II B meets the needs of every type of residential building with a decentralized system.

They have been designed to speed up the installation phases, as the indoor unit contains the main components needed for the plumbing and heating system.

Air Inverter II - B adapts perfectly to systems with radiant panels, fan coils, storage tanks for domestic hot water.
