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.
GLRC 2015 – 4160 CD2 (41 – 442 kW) Equipment: • Standard configuration with 2 or 4 scroll compressors • On-site condenser, air-cooled or water-cooled • Pump module optional (hydraulics module GLPE) additionally with safety valve, venting and filler connection; unit dimensions change when using the pump module • Autoadaptive microprocessor control • Unit main switch • Automatic circuit breakers for all electric consumers • Controller type: HVAC Systems-Step I (2015 – 2061) HVAC Systems-Step II (4060 – 4160) • Master/slave operation with GEA HVAC System unit series available as an accessory item • Connection to BMS via optional interface
- Building with little space for outside installation - Increased requirements on the sound level - Building listed as architectural landmark - Use of antifreeze agents not allowed
