Rittal have extended their range of air-water heat exchangers to include units of 4kW and 5kW.

The units can be mounted on the enclosure roof or wall and have been manufactured for 230V electrical supply. Equipped with modern electronic safety devices, including condensate sensors and collective fault signals, so that if, at any time, a component stops functioning, the rise in temperature will immediately signal the alarm. The design of these units incorporates only two working parts, a solenoid valve to regulate water and a fan unit to circulate cool air.

The body is protected using a multi-level paint finish to minimise both degradation and maintenance whilst maximising reliability.

Both versions have been constructed using high airflow fan units to increase enclosure air change rates, as well as a new advanced cooling circuit, to assure high cooling power even with low water flow rates or higher water temperatures.

Both units are supplied with accessories to allow external or internal mounting, and include a multi-lingual installation manual.

The units are stocked comprehensively within the UK and are available off the shelf for immediate delivery.
