Datasheet Certificates / CE Certificates / CE

Circular cold water cooling battery, easy to install and with a removable service panel allowing access for cleaning the coil

Application

Zone cooling

Material

Casing made of galvanised sheet steel with 9 mm synthetic cellular rubber anti-condensation insulation, the circular connections are equipped with an EPDM rubber.
The coil consists of copper tubes with aluminium fins.
Drip tray made from stainless steel.

Mounting

Circular ducts

Accessoires

2 or 3-way regulation valves, type QCV-2 or QCV-3

Text for tender

The cooling coil shall be made out of copper tubes with aluminium fins, the copper tubes shall be positioned zig-zag this for an effective and econmic cool transfer from the circulated cooling medium to the air. The casing of the cooling coil shall be made of galvanised steel sheet with 9 mm synthetic cellular rubber anti-condensation insulation the circular connections on the casing are equipped with a solid EPDM rubber. The casing of the cooling coil shall have a removable service panel this to inspect the coil and clean it.

Order example
