Remko Air conditioning cold water KWK 220 EC 1662510

Chilled water chest unit for wall or ceiling mounting in a two-pipe system with infinitely variable EC fan.

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-mounted) or horizontal (ceiling-mounted) via elegant outlet grille made of white plastic with side control panel for optional room temperature control.
A smooth-running, low-noise centrifugal EC fan with infinitely variable, 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 register connection side and the condensate connection can be exchanged.
Insulated condensate tray made of sheet steel for vertical and another for horizontal installation.
The appliance can be operated either via an internal (3-stage) or external (stage or stepless via 0-10V signal) room temperature control.

The medium volume flow 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.

Available as accessories:
Condensate pump, room temperature control for surface mounting, room temperature control for mounting in the appliance, switching relay for 4 appliances, 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 appliances comply with the relevant EU regulations and are CE-marked in accordance with the applicable directives.
