Air-cooled Chillers for Indoor Installation

With duct connection or without condenser

Always when space requirements outside the building is limited, or the architecture or heritage protection of the building forbids installation of exterior units, or when no anti-freeze agents can be used, the air-cooled chillers for inside installation are suitable for air conditioning. Also special requirements on the sound level can be a good argument for this ranges of models.

The GLDC series has centrifugal fans and is therefore suitable for air-side connection to an on-site duct system.

Units of the GLRC series in split-design are connected via refrigerant tubes to an air-cooled condenser.
