Rittal Blue e cooling units can save energyRittal’s Blue e cooling units have the same nominal cooling output, physical size and cut-out dimensions as the equivalent Rittal Basic cooling unit and can realise energy savings of up to 45 per cent.

Prices of the vast majority of Blue e cooling units have now been reduced. The maximum premium compared with the equivalent Rittal Basic cooling unit is 10 per cent. In fact, the Blue e cooling unit can in some instances be the more cost-effective product.

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 cooling unit can be checked at a glance.

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

Adjustment of the minimum cooling setpoint of 20degC and the switching hysteresis in the range 2–10 K, which governs when the unit switches off, is both quick and easy using the buttons mounted on the fascia of the controller. Passcode protection serves to both restrict access and prevent accidental adjustment.

Rittal’s RiDiag II is a useful set-up, diagnostic and data acquisition tool that may be used in conjunction with the TopTherm Blue e cooling unit. Not only does this software allow operating settings to be viewed and adjusted, it can also be used to log equipment data and track performance indicators in real time, displaying them in a graphical format.
