Simple fan-and-filter units are often not enough to dissipate high heat loads from enclosures.
Alongside modern compressor cooling units, which also cool with air, liquid-based cooling systems offer major advantages, depending on the application.
Recent developments in heat exchangers have led to improvements in energy efficiency, assembly handling and availability.
To increase the energy efficiency of the entire cooling system, Rittal has improved its current air/water heat exchangers.
New and intelligent Eco Mode controls are now used with comfort units with cooling outputs of 500 W to 5000 W.
They 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 seconds every 10 minutes to maintain circulation.
The new units also offer assembly benefits and can be mounted to the enclosure in less than two minutes. The heat exchangers are held in place by simply snap-fitting them to pre-mounted fixtures. Only two screws are needed to fasten the devices securely.
Assembly is performed entirely from outside, without the fitter having to fasten the air/water heat exchanger from within. Rittal has also improved the water connections.
