Rittal Blue e+ S Wall-Mounted Cooling Unit 1.0 kW 400x950x196 mm

Rittal's Blue e+ S wall-mounted cooling unit brings inverter-driven compressor control to compact enclosure climate management. Unlike conventional on/off cooling units that cycle at full power, the Blue e+ technology continuously adjusts compressor speed to match the actual heat load. This results in significantly lower energy consumption, reduced temperature fluctuations inside the enclosure, and extended component lifespan. With a cooling capacity of 1.0 kW (L35 L35) and a footprint of just 400x950x196 mm, it is ideal for space-constrained industrial environments where reliable thermal management is critical.

Highlights

• Energy-efficient Blue e+ inverter technology for reduced power consumption
• IP55 protection on both internal and external circuits for dust and water resistance
• Wide voltage input (110–240 V, 1~, 50/60 Hz) for flexible installation
• Compact wall-mounted design: 400 mm width, 950 mm height, 196 mm depth
• Operates in ambient temperatures from +10 °C to +55 °C
• Low noise level at 62 dB(A)

In daily use

The Blue e+ S is engineered for continuous operation in demanding factory settings. Its sheet steel housing withstands mechanical stress, while the IP55 protection on both circuits prevents ingress of dust and water jets, making it suitable for washdown areas. The unit mounts directly onto the side panel of an enclosure, saving valuable floor space. The terminal strip connection simplifies electrical installation, and the wide voltage range allows use in various global power networks without additional transformers. The R134a refrigerant ensures reliable cooling across the specified ambient range, and the low sound power level of 62 dB(A) keeps workplace noise to a minimum.
