Application

Suitable for domestic and commercial applications.

Description

Danfoss Cooling Interface Units (CIUs) for indirect cooling enabling the primary circuit to be kept hydraulically separate. These are supplied with fully insulated and vapour sealed enclosures, designed to prevent condensation of the internal valves and pipes. Insulated enclosures means that the Danfoss CIU components can be left uncovered, which makes access for maintenance tasks considerably easier.


All Danfoss CIUs are supplied with the Danfoss Electronic Controller (ECL). The ECL's are intelligent temperature regulators for heat networks and communal heating. By means of weather compensation and application keys, they can be adapted to a variety of project specific requirements, ensuring a high level of comfort and optimum energy utilisation.
