AHU connection kit for ECOi and ECO G

AHU connection kit combines air conditioning and fresh air in just one solution.

New AHU connection kits connect ECOi systems to air handling unit systems, using the same refrigerant circuit as the VRF system.
Large connectivity possibilities mean the Panasonic AHU connection kit can be easily integrated.

Solution for hotels, offices, server rooms or all large buildings where air quality control such as humidity control and fresh air and is needed.

The Panasonic AHU connection kits offer a wealth of connectivity possibilities so can be easily integrated into many systems.
Besides the advantages in terms of indoor air quality, air conditioning offers also an energy saving potential. For example, while uncontrolled ventilation through open windows leads to large amounts of heat being lost to the outside during the heating season or gained from the outside during the cooling season, air conditioning systems provide possibilities to utilize the extra “free” energy in heat recovery modules so that overall operating costs will be reduced.
The larger area of the comfort range, the better the energy saving opportunities.
