Environ - Mitsui monobloc units are characterized by integrated cooling and hydronic modules that make it possible to extract heat from the outside air and thus heat the interior and vice versa.
They are therefore a bivalent, ecological and renewable solution. They can be positioned directly on the outside wall, on the ground or on the roof.

Why choose an Environ - Mitsui heat pump?

✓ Mitsui systems, thanks to an appropriate design of the structural components and the thermodynamic cycle, are able to guarantee a high level of efficiency and adapt to any climatic condition. They guarantee the synergy between the devices of the system and adapt to the energy needs of the moment, in order to achieve optimal comfort both in winter and in summer.
The Mitsui heat pump range offers a wide range of products ranging in power from 4 kW (single phase) to 16 kW (three phase). They are suitable for any type of building, whether it is a renovation or a new build

✓ Mitsui offers two lines of heat pumps, one for heating and one for domestic hot water: the line of monobloc units and the line of split units. Both lines belong to the A++ class (see European legislation on energy efficiency) and contribute significantly to reducing the environmental impact, achieving significant energy savings and a reduction in running costs
will. In order to completely complete its own range of heat pumps, Mitsui has decided to expand its range with air-to-water heat pumps, only for hot water generation. The line of monobloc water heaters is equipped with three different tanks for storing domestic water: 100 liters, 180 liters and 280 liters. For the last two sizes, the tanks can be completed using a solar thermal coil or other additional heat source of 1.1 m2 for the second size and 1.3 m2 for the third size. This line of products guarantees class A+ according to the ErP directive, helping to limit operating costs and environmental impact.
