USEThe water cooled packaged DYNACIAT chillers-heaters LGseries of CIAT are specially designed to supply chilled wateror hot water with a middle capacity for air conditioning applications systems encountered in collective and commercial buildings , as well as industrial premises and processes.These packaged units must be settled in standard indoor ina technical plant, sheltered against adverse weather andfrost.To operate on COOLING mode, these units must be cooledby a water circulation coming from an external source, likeunderground water or city water if using a water flow controlvalve, or connected to an external water drycooler or acooling tower.

On a water supply, the LGP series can be used as a heatpump during winter time.

Connected to an heating or cooling floor, fan coil units or onan air handling unit, an heat pump series LGP allows the heating and the air conditioning of buildings thanks to a setof valves located on the water circuit (not supplied).Each unit is assembled, internally wired (logic and startingbox), charged with refrigerant, and is subject to a operationtest in the factory.The installation work is simple, and the only operations required on spot are field electrical wiring and water pipingconnections.

MINIMUM WATER PIPES VOLUMEThe Connect controller is equipped with an anticipation logic allowing high flexibility in adjusting the set points according to theparameters drifting, in particular for low water volume hydraulic installations.An adapted management of the compressors operating periods avoids therefore the start of anti-short cycle functions, and inmost cases, the requirement of a buffer tank.

Notes :Industrial processes which require a high stability of water temperatures or installations with high thermal load variation can privilege the installation of a water buffer tank.
