Heat Doesn't End With Summer

Trapped enclosure heat shortens component life and turns into unplanned downtime, in January as much as in July. Rittal climate control holds the temperature your controls expect, all year.

Why Rittal Cooling Units

Up to 75% energy savings

An average of 75% energy savings on Blue e+ and Blue e+ S, from speed-regulated components and heat pipe technology.

One unit, many voltages

Blue e+ multi-voltage capability with country-specific approvals, supporting 110–240 V on a single model.

Monitor from anywhere

Intelligent monitoring over the IoT interface, and the Rittal Scan & Service app.

Built for the plant floor

UL Type 12 rated, RiNano hydrophobic condenser coating, and R-513A refrigerant.

Cool Smarter, Not Harder

3 Families, 1 Job

TopTherm Blue e The workhorse. 0.32 to 2.75 kW, one fixed supply voltage per model, for indoor enclosures from 10 to 50 °C.

Blue e+ The efficient one. 1.6 to 5.5 kW, one unit takes 110-240 V or 380-480 V, and runs from -20 to 60 °C.

Blue e+ S Blue e+ efficiency in small sizes. 0.3 to 0.52 kW, multi-voltage, about twice as efficient as a same-size TopTherm.
