SK3127.100 Rittal TopTherm air/air heat exchanger Wall-mounted with controller

Why Choose the Rittal SK 3127.100 TopTherm Air/Air Heat Exchanger?

The Rittal SK 3127.100 is a high-performance TopTherm wall-mounted air/air heat exchanger with electronic controller designed for effective thermal management of industrial electrical enclosures. By maintaining completely separate internal and external air circuits, it allows heat to be transferred away from sensitive equipment without introducing contaminated ambient air into the enclosure.

This design makes the SK 3127.100 particularly suitable for industrial environments where dust, dirt or other challenging ambient conditions make direct ventilation undesirable. The unit is supplied fully wired and ready for connection, with an electronic controller and digital temperature display providing straightforward monitoring and control of enclosure temperature.

With a specific thermal output of 30 W/K, air throughput of up to 525 m³/h and a 230 V AC single-phase supply, the SK 3127.100 provides dependable enclosure cooling for industrial automation and control equipment. The internal air circuit achieves IP54 protection, while the compact wall-mounted format measures 400 × 950 × 205 mm.

Reliable Thermal Management for Industrial Enclosures

Air/air heat exchangers provide enclosure cooling by transferring heat between two separate airflow circuits rather than introducing outside air directly into the enclosure. This helps maintain the integrity of the enclosure while allowing excess heat generated by drives, power supplies, PLCs and other electrical equipment to be dissipated.

The Rittal SK 3127.100 uses completely separated internal and external air circuits, making it particularly useful where ambient air contains dust or other contaminants. Its electronic controller, digital temperature display and overtemperature fault signal provide convenient monitoring, while the IP54 internal circuit helps maintain protection for the enclosed equipment.

Typical Applications

• Industrial electrical control enclosures.
• Automation and PLC control panels.
• Machine-building electrical cabinets.
• Manufacturing and production machinery.
• Drive and motor-control enclosures.
• Switchgear and power distribution cabinets.
• Industrial environments with dust or contaminated ambient air.
• Applications requiring enclosure cooling with separate internal and external airflow circuits.
