Remko Air conditioning cold water KWK 680 1662300

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

Easily removable unit cover made of galvanised sheet steel with white base coat and polyester coating, similar to RAL 9016.
Vertical air inlet on the underside of the unit with large, regenerable air filter. Air outlet vertical (wall mounting) or horizontal (ceiling mounting) via elegant outlet grille made of white plastic with control panel on the side for optional room temperature control.
A smooth-running, low-noise centrifugal fan with three-speed 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. 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 and another for horizontal installation.
The appliance can be operated either via an internal or external room temperature control system.

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

Available as accessories:
Condensate pump, room temperature control for surface mounting, room temperature control for mounting in the unit, switching relay for 4 units, heating coil for four-pipe system, valve assembly for two-pipe system, valve assembly for four-pipe system, feet, air inlet base, electrical heating resistor, fault signalling module

The units comply with the relevant EU regulations and are CE-marked in accordance with the applicable directives.
