Remko Air conditioning cold water KWK 125 1664100

Chilled water chest unit for wall or floor mounting in a two-pipe system.

Chilled water chest unit for wall or floor mounting for cooling and heating in a two-pipe system and standard unit housing. 3-speed fan with minimum motor speed at the lowest speed enables particularly low noise emissions for rooms with high acoustic requirements. Can be retrofitted to four-pipe system.

Easily removable unit cover made of galvanised sheet steel with white base coat and polyester coating, similar to RAL 9010.
Vertical air inlet on the underside of the unit with large, regenerable air filter of filter class Iso Coarse 45% in accordance with EN ISO 16890. Vertical air outlet (wall mounting) via elegant outlet grille made of white plastic with side access to optional control panel for direct control of the unit.
A smooth-running, low-noise centrifugal fan with three-stage adjustable, thermally protected drive motor, statically and dynamically balanced.
Air cooler or air heater as heat exchanger in Cu/Al design made of seamlessly drawn copper pipe with form-fit aluminium fins for cold or hot water or water/glycol mixture up to max. 80°C. Tightness tested at the factory up to 30 bar. Brass pipe connections in imperial design with bleed and drain valves provided on the left-hand side of the appliance at the factory. Depending on the installation variant, the coil connection side and the condensate connection can be exchanged.
Insulated condensate drip tray made of sheet steel for vertical installation.
The appliance can be operated either via an internal or external room temperature control system.

The medium flow rate can be controlled by an optional 3-way or 2-way valve assembly in the appliance. The appliance can be extended for a four-pipe system by installing an additional heating coil.
