Cooling units

Rittal's Blue e cooling units have the same nominal cooling output, physical size and cut-out dimensions as equivalent Rittal Basic cooling units and are reported to be capable of energy savings of up to 45%.

With additional monitoring functions on the 7-segment display that include high condensate level warning, clogged filter mat alarm, enclosure internal temperature and any error messages, the health of the unit can be checked at a glance.

Suites of encosures that are not divided internally may need multiple cooling units to function as a system. Using the SK BUS system, up to 10 Rittal Blue e cooling units may be connected in a master and slave configuration.

Adjustment of the minimum cooling setpoint of 20°C and the switching hysteresis in the range 2 to 10K, which governs when the unit switches off, is easy using buttons on the fascia of the controller. Passcode protection is included.

Prices of Blue e cooling units have been reduced; the maximum premium compared to the equivlent Rittal Basic unit is now 10% and in eight instances the Blue e cooling unit is said to be the more cost effective.
