New Blue e chillers from 11 to 25 kW

22 July 2019

Rittal has improved its cooling technology for machines and enclosures with the new ‘Blue e’chillers in the 11 to 25 kW output class range. Using 40% less refrigerant, the devices making a contribution to sustainable environmental protection.

The recooling of liquids by means of chillers is one of the basic requirements for smooth operation in many industrial manufacturing processes. As well as the Blue e+ chillers with 1.5 to 6 kW, the chillers are now available in the robust industrial standard (IP 44, electrical) in four output classes ranging from 11 to 25 kW and in the two enclosure sizes of 660 x 1265 x 1315 mm and 760 x 1265 x 1515 mm. in addition to Blue e+ chillers from 1.5 to 6 kW. Thanks to the use of micro-channel technology and the resulting very high fin efficiency of the heat exchangers the devices require 40% less refrigerant than before. Since the heat exchangers are 100% made of aluminium, galvanic corrosion cannot occur.

Blue e Chillers are wired ready for connection and can be quickly put into operation. Integrated overflow valves ensure a constant circulation of cooling water when the consumer is closed and the pump is running. This protects the coolant pump from overload. The valve is pre-set for the pump being used and for 50-Hz operation but it can also be set for 60-Hz operation. A filling level monitoring system ensures maximum reliability and improved availability. Besides this, optional flow monitors emit an alarm if the flow rate is too low and they can detect hydraulic errors such as contamination and blockages in the system at an early stage.
