Built-in display air-to-air heat exchanger Rittal SK 3127100, 30,000 W, 230 V, stainless steel, grey

The Rittal SK 3127100 built-in display air-to-air heat exchanger is designed for cabinet and enclosure climate control in industrial settings. With a cooling capacity of 30,000 W and operation on 230 V at 50/60 Hz, it offers high-capacity heat dissipation for electrical cabinets. Constructed from stainless steel with a grey finish and featuring an integrated controller and digital temperature display, this wall-mounted unit separates internal and external air circuits to protect sensitive components from aggressive ambient conditions.

Advantages

This heat exchanger provides a high cooling capacity suitable for large enclosures while keeping installation compact as a wall-mounted unit. The integrated controller and digital display allow straightforward monitoring and regulation of cabinet temperature. Stainless steel construction increases corrosion resistance in harsh environments, and the separated air circuits prevent contamination of internal cabinet air by external pollutants.

Suitable for

• Industrial electrical enclosures and control cabinets requiring efficient heat removal
• Applications with aggressive ambient conditions where separation of air streams is necessary
• Wall-mounted installations where built-in display and controller access is preferred
• Environments needing stainless steel components for corrosion resistance

When it may not be suitable

This unit is intended for applications where an air-to-air solution is appropriate; it is not suitable if liquid cooling or refrigeration-based climate control is required. It may be oversized for small cabinets or low-power applications where a lower cooling capacity would be more efficient and economical.

Key specifications

• Cooling capacity: 30,000 W
• Supply voltage: 230 V, 50/60 Hz
• Operating current: 0.68 A
• Material: stainless steel, grey finish
• Mounting: wall-mounted / built-in display
• Integrated controller with digital temperature display
• Air-to-air design with separate internal and external air circuits

How to use

Mount the unit according to enclosure manufacturer guidelines and ensure correct electrical connection to a 230 V supply by a qualified technician. Configure the integrated controller and set the desired cabinet temperature using the digital display. Maintain clear airflow paths around inlet and outlet openings and observe recommended minimum clearances. Regularly inspect filters, heat-exchange surfaces and controller settings to ensure continued performance.

What to consider before purchase

• Verify that the 30,000 W cooling capacity matches the heat load of the enclosure
• Confirm available mounting space and clearances for wall-mounted installation
• Ensure compatibility with site supply voltage and electrical installation standards
• Assess environmental conditions to determine need for stainless steel construction

Usage recommendations

For reliable operation, install the heat exchanger in a location with unobstructed airflow, set the controller to maintain target temperature ranges suitable for installed equipment, and schedule periodic inspections of filters and heat-exchange surfaces. Use the separated air circuits to protect sensitive components from external contaminants.
