Remko Air conditioning cold water KWK 680 ZW 1662305

Chilled water chest unit for installation in intermediate spaces for wall or ceiling mounting without cover in a two-pipe system.
Casing made of dimensionally stable sheet steel, fully insulated.
Integrated, low-noise centrifugal fan with three-speed adjustable, thermally protected drive motor, statically and dynamically balanced.
Air inlet from the rear (horizontal) or bottom (vertical) with large-surface
Air outlet at the front (horizontal) or top (vertical) via a free air outlet opening to accommodate a connection duct.

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 tray made of sheet steel for vertical installation and another condensate tray made of sheet steel for horizontal installation. Condensate connection on the side of the appliance.
Electrical connection terminals on the side of the appliance.
The medium flow rate can be regulated using an optional 3-way valve assembly on 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, switching relay for 4 devices, heating coil for four-pipe system, valve assembly two-pipe system, valve assembly four-pipe system, duct angle 90° air inlet, duct angle 90° air outlet, grille in aluminium, for air inlet, grille in aluminium for air outlet, electrical heating resistor, fault signal module

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