Rittal air/water heat exchangers featuring eco mode controls

Monday, 27 February, 2012

Rittal has added Intelligent Eco Mode controls to its air/water heat exchangers for increased energy efficiency. The Comfort units have cooling outputs of 500 to 5000 W and turn the fan off or on as needed, depending on the temperature in the enclosure.

If the internal temperature falls 10°C below the set temperature, the fan switches off. In order to measure the effective internal temperature of the enclosure, the control system switches on the fans for 30 s every 10 min, ensuring a circulation of air in the enclosure.

The company has also made improvements to assembly and water connections, claiming that the new units can be mounted to an enclosure in less than 2 min. Heat exchangers are snap-fitted to premounted fixtures and only two screws are required to fasten the devices securely. Assembly is performed entirely from outside, without the fitter having to fasten the air/water heat exchanger from within.

Alongside standard water connections with flexible hose and plug-in joints and couplings, other types of joint are also available, such as internal threads, quick-release fasteners, direct hose ports or Ermeto quick-release systems.
