CVK4 Climaconvectors are heating and/or cooling unitary products that are designed for installing them in-floor, the most commonly alongside the fully glazed outer walls and facades of the building. Thanks to blowing the hot air during the winter time and the cold air during the summertime. Thanks to that they keep the appropriate micro-climate in the dedicated rooms. CVK4 Climaconvectors include two separate pipe and connection circuits – two for heating installation, another two for chilled water installation.

Thanks to the highly efficient coil heat exchanger that is used for heating and for cooling and the fan itself that is made in EC technology and supplied with the H&S 24V DC those units are considered as ideal for any low water temperature applications for example installation fed by the heat pumps.

The dedicated system for the units controls, wireless controllers or the solutions that allows connecting CVK Climaconvectors to the BMS system that are based on the BACnet, KNX or Modbus protocols make the Climaconvector workable in any building environment, independently to planned and maintained installation regulation and balancing system.

    VER-24 or VERS that controls the fan and actuators to provide the expected ambient temperature in the room. According the actual requirements, it operates to raise the temperature in the room (heating mode), or to decrease temperature in the room (cooling mode).

    Possible manual adjustment or automatic fan speed regulation (in the automatic mode). The control for opening and closing the ON/OFF actuator is available (ON/OFF water side, according to the requirement). Also the 0-10V (by adjusting the angle of the valve closing that reflects the current water capacity needs).

    VER-24 and VER24S are directed to exposed wall assembly. Connection box fi=60 is required.

    Both VER-24 and VER-24S require 24V DC current electrical supply.
