EDITOR ’ S CHOICE RITTAL BLUE E + S COOLING UNITS
RITTAL
Cool successor with sustainable DNA
Rittal is expanding its smart cooling unit solutions by adding the new Blue e + S range . Our latest generation of cooling units with their lower output categories of 300 , 500 , and 1,000 W have been designed for efficiency , ensuring a smaller footprint and lower costs – just like their “ bigger brothers .” So it ’ s a win-win both for users and for our future .
Solutions that reduce our carbon footprint during production are in high demand . But at the same time , these solutions need to be intelligent and communication-enabled so that they can be easily integrated into digitalised manufacturing environments . Seven years ago , Rittal responded to this demand with its Blue e + range of cooling solutions and launched extremely efficient enclosure cooling units , which provided on average energy savings of 75 percent . Now we have a new generation – the next generation – but still developed with that same design DNA . These new cooling units with their lower cooling outputs of 300 , 500 , and 1,000 watts called “ Blue e + S ” add to the Blue e + family and bring with them additional smart capabilities . And furthermore , this new generation offers innovative energy-saving features for the production process .
What ’ s behind this energy-saving and therefore cost reduction is the technology used , combining a heat pipe with inverter-controlled components .
What ’ s behind this energy-saving and therefore cost reduction is the technology used , combining a heat pipe with invertercontrolled components . The heat pipe works without a compressor , expansion valve , or other regulating elements and so does not need any electrical energy except to operate the fan . Depending on the thermal energy generated in the enclosure and the current ambient temperature , cooling can be performed with the heat pipe alone . The additional compressor cooling only operates if a large amount of heat has to be dissipated from the enclosure or if the ambient temperature is very high . And what ’ s more – when it does operate , it is far more energy-efficient than conventional units . This is because the compressor and fans possess an inverter-controlled drive , which automatically adjusts their speeds depending on the requirements . As a result , the temperature within the enclosure remains constant , and the energy efficiency is significantly higher than with other more conventional cooling units .
STAYING COOL ALL THE TIME
Alongside energy efficiency , another feature also reduces the carbon footprint : The new Blue e + S series uses a refrigerant with a GWP ( Global Warming Potential ) that is 56 percent lower than those used in comparable cooling units . Furthermore , instead of the R-134a previously used , the cooling circuit in the new generation of units now runs with R-513A refrigerant .
SMART COMMUNICATION-ENABLED CAPABILITIES
With their additional smart functions , the new cooling units also help in the digitisation process . With a fully integrated IoT interface as standard , the cooling units can be intelligently monitored in digitalised environments and easily connected to Rittal ’ s new Smart Service Portal .
