About Air Conditioner (AC) Units for Enclosures & Cabinets

Enclosure cooling units are the most widely used and most flexible solution for the dissipation of heat from enclosures and electronic cases in industrial environments. They have a high cooling capacity (300 – 6,000W) enabling the enclosure’s internal temperature to be cooled to well below the ambient temperature. This makes air conditioners an ideal option for hot and humid locations that have an ambient temperature up to 130°F.

Why Rittal Wall-mounted Air Conditioner?

Rittal’s entire range of enclosure cooling units are certified with TÜV-tested DIN EN standard performance. This verifies that cooling outputs are 10% higher than previously claimed and ensures an improved energy efficiency ratio (watts of cooling divided by watts of power consumption).

TopTherm Blue e Cooling Unit

Rittal’s TopTherm Blue e wall-mounted air conditioners provide both high output and energy efficiency. It’s eco-mode precision adjustment with the Comfort Controller ensures that cooling rates are steady. Nano-coated condenser coils and integrated condensate evaporator resist corrosion and reduce maintenance time and cost while maintaining reliable cooling capacity.

    • Integrated Condensate Evaporator

Blue e+ Cooling Unit

The Blue e+ wall-mounted cooling unit pioneers new standards in cost-effectiveness and energy conservation. Hybrid climate control merges speed-regulated components with patented heat pipe technology. On average, this combination saves up to 75% in energy costs over existing cooling solutions. Blue e+ units also offer a range of powerful new features that provide longer component life, flexibility and ease of use.
