[Energy-Saving Design] Non-CFC Control Panel Coolers "Blue e+" and "Blue e+ S" Newly Released

The energy-saving control panel coolers "Blue e+" and "Blue e+ S" series adopt hybrid cooling technology, operating as a cooler when ambient temperature is higher than the panel's internal temperature, and as an air-cooled heat exchanger when ambient temperature is lower than the panel's internal temperature. Rittal Corporation (Representative Director: Taku Niioka, hereinafter Rittal, Yokohama City, Kanagawa Prefecture) has newly added non-CFC models (refrigerant R-1234yf) to its energy-saving control panel cooler "Blue e+" and "Blue e+ S" series, as part of its initiatives towards a sustainable future. Refrigerant R-1234yf is already widely adopted and established in the Japanese market for automotive air conditioning systems and temperature management in Japanese enclosures. Meanwhile, in Europe, the F-gas regulation aimed at reducing greenhouse gases has been strengthened in recent years, making the transition to cooling solutions with significantly reduced global warming potential (GWP) of refrigerants an urgent task. In EU countries, products with a GWP value of less than 150 are expected to be restricted from January 1, 2027. Against the backdrop of the full-scale implementation of these European regulations and the mature non-CFC operational track record in pioneering markets including Japan, Rittal is rapidly transitioning to non-CFC refrigerant R-1234yf (GWP 0.5), which complies with global F-gas regulations. *GWP is an index indicating the impact on global warming with CO₂ as a reference value of 1, and is used as a basis for international climate policy. A GWP of 0.5 achieves an extremely low value, almost equivalent to CO₂. ■ Non-CFC Control Panel Coolers Blue e+ / Blue e+ S These products inherit the features of the highly acclaimed "Blue e+" and "Blue e+ S" series for their energy-saving performance and high cooling capacity, while being non-CFC control panel coolers that reduce environmental impact and are not subject to the Fluorocarbons Emission Control Law. The "Blue e+" non-CFC model is available in side-mounted and roof-mounted types. The output class ranges from 1.3kW-5.5kW. Wall-mounted cooling unit Blue e+ 1.6 – 5.5 kW Roof-mounted cooling unit Blue e+ Total cooling capacity 1.30 kW The "Blue e+ S" non-CFC model offers an output class of 0.3kW-0.92kW. The introduction of an LED light bar makes the operating status visible at a glance from a distance. Wall-mounted cooling unit Blue e+ S 0.3 kW – 1 kW Download materials [Main Features] Refrigerant R-1234yf adopted, global warming potential is 0.5: Design that does not use refrigerants subject to the Fluorocarbons Emission Control Law, achieving both compliance with environmental regulations and long-term reliable operation in manufacturing sites. Industry's first hybrid cooling technology: In addition to conventional inverter-controlled compressor cooling, a heat pipe cooling circuit is also installed. It operates as a cooler when ambient temperature > panel internal temperature, and as an air-cooled heat exchanger when ambient temperature < panel internal temperature, achieving up to 75% energy savings (compared to our company). Filterless: Unique RiNano coating applied. No need for filter installation or replacement, significantly reducing maintenance costs and workload. *Various filter accessories can also be used depending on environmental conditions. Non-drainage system: Built-in drain evaporator eliminates troublesome drain water treatment. *Drain water treatment may be required if the control panel's airtightness is insufficient. Network: Rapid parameter setting/changing and diagnosis via Scan & Service app via Near Field Communication (NFC). Remote monitoring via IoT interface. Complies with international standards: Various international certifications obtained. Supports multi-voltage for worldwide use, enabling use in various equipment and applications both domestically and internationally. Rittal is used in various industries such as automotive, machine tools, food, semiconductors, and infrastructure. Rittal's non-CFC control panel coolers can simultaneously achieve environmental consideration, energy saving, and low maintenance, contributing to stable operation of control panels and total cost reduction. We offer products made of steel plate, stainless steel, outdoor specifications, vibration-resistant types, and environmental-resistant specifications. Headquartered in Germany, Rittal is one of the world's leading system suppliers in the fields of hardware, software, and automation. Since its founding in 1961, it has developed standardized products such as boxes, enclosures, racks, temperature control solutions including control panel coolers, and power distribution systems, providing products of stable quality globally through its production system in 13 locations across 6 countries.
