Vibration Tested Air-Air Heat Exchangers

Rittal has developed an air-to-air heat exchanger, which has been specifically tailored to cater for the needs of the mobile railway engineering industry. Available in both 24VDC and 100VDC versions, the exchangers have been constructed to EN 50 155, and vibration tested to EN 61 373.

Offering long-term reliable cooling, the exchangers extract heat from inside the enclosure to the surrounding environment, using only two working parts. Two fan motors housed inside the exchanger control the internal and external airflows indenpendently. The exchanger matrix, made from aluminium, is light but durable, and spray finished in RAL 7035 S to DB TL 918340.

Air-to-air heat exchangers offer a simple platform for servicing due to their simplicity. Filter mats are available for dirty environments, as well as a matrix module, which can easily be removed for cleaning with compressed air in less than five minutes. Quick connect plug electrical connections and the modular constructed fans allow fast serviceabiity and rapid replacement of parts in the event of failure.

Digital controllers monitor the internal temperature so if an enclosure reaches a pre-determined set point, an alarm is displayed. A fault signal can also be sent via a floating contact.
