Environ - Mitsui monoblock devices are characterized by integrated cooling and hydronic modules, which 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 floor 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 ensure a high level of efficiency and adapt to any climatic condition. They guarantee synergy between the devices in the system and adapt to the respective energy needs to achieve optimal comfort in both winter and summer.
The Mitsui heat pump range offers a wide range of products ranging in power from 4kW (single phase) to 16kW (three phase). They are suitable for any type of building, regardless of whether it is a renovation or a new build
✓ Mitsui offers two product lines of heat pumps, each for heating and hot water production: the line of monoblock devices and the line of split devices. Both lines belong to class A++ (see European legislation on energy efficiency) and contribute significantly to limiting environmental impact, achieving significant energy savings and a reduction in operating costs
become. In order to completely complete its own heat pump range, Mitsui has decided to expand its range with air-water heat pumps, solely for hot water production. The line of monoblock 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 storage can be completed with 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 product line guarantees Class A+ according to the ErP directive and helps to limit operating costs and environmental impact.
