Following the successful launch of Rittal's new cool efficiency 1kW cooling unit earlier in 2009, Rittal has now added a 2kW unit to the portfolio. The cool efficiency products are claimed to be up to 45 per cent more economical to run than conventional cooling units of the same cooling output, and CO2 emissions are correspondingly reduced as well. The units have been developed using the latest EC fan technology and incorporate the Rittal nano-coated condenser and condensate management system as standard.
The new cool efficiency label from Rittal, in accordance with DIN EN ISO 14021, identifies all cooling systems that make a significant contribution to environmental protection. These new cooling systems are said to far exceed the requirements of DIN 3168 and meet all three requirements of the new efficiency label.
In heavily contaminated environments it is vital to keep units clean in order to maintain efficiency. Over time, performance can deteriorate by between 30 and 50 per cent if membranes become dirty, leading to an increase in CO2 emissions. RiNano is a thin coating that repels oil, dust and powder particles, thereby preventing them from attaching to the condensers. In industrial operations in particular, the air is often so contaminated with dust and dirt particles that the filter mats used in traditional cooling units have to be replaced and disposed of very frequently; but with Rittal TopTherm PLUS and RiNano technology, filter mats become obsolete.
