Why Choose the Rittal SK3126.100 TopTherm Air/Air Heat Exchanger?
The Rittal SK3126.100 is a wall-mounted TopTherm air/air heat exchanger with controller designed to provide efficient thermal management for electrical enclosures and control cabinets. As part of the advanced Rittal TopTherm climate control range, it maintains enclosure temperatures without allowing external and internal air circuits to mix, making it suitable for demanding industrial environments.
This air/air heat exchanger uses separate internal and external air circuits to transfer heat while protecting the enclosure contents from contaminated ambient air. The integrated electronic controller with digital temperature display enables precise monitoring and regulation of enclosure conditions.
With a specific thermal output of 17.5 W/K, a 230 V AC single-phase supply and IP54 protection for the internal circuit, the SK3126.100 provides reliable cooling performance for automation cabinets, electrical enclosures and industrial control systems.
