June 13, 2022 – Rittal unveiled the next generation of Blue e+ cooling units—Blue e+ S—boasting cooling outputs of 300W, 500W, and 1000W, and additional “smart” capabilities.

The S series combines a heat pipe with inverter-controlled components. The heat pipe works without a compressor, expansion valve, or other regulating elements, meaning no additional electrical energy is required (except to operate the fan). Depending on the thermal energy generated in the enclosure and the ambient temperature, cooling may be performed with the heat pipe alone.

The new Blue e+ S series uses a refrigerant with a GWP (global warming potential) that is 56% lower than those used in comparable cooling units, says Rittal.

The units come with a fully integrated IoT interface as standard; they can be monitored in digital environments, and connect easily to Rittal’s Smart Service Portal.
