Built-in Cooling Unit Rittal SK 3312810 — 1050 W input, 110–480 V, 50/60 Hz, steel housing, grey

The Rittal SK 3312810 built-in cooling unit provides targeted climate control for electrical enclosures, control cabinets and server racks. Designed for installation into a cabinet wall, this unit accepts a wide input voltage range of 110–480 V at 50/60 Hz and delivers an input power rating of 1050 W. The housing is steel and finished in grey for robust protection and a neutral industrial appearance. The manufacturer lists a maximum cooling capacity up to 3000 W, making the unit suitable for a variety of indoor industrial and IT cooling applications.

Advantages

This built-in cooling unit combines a wide supply-voltage capability with a compact steel housing for dependable operation in distributed environments. The unit supports both 50 Hz and 60 Hz installations and is specified with a clear input power value, which simplifies electrical planning. The grey steel enclosure offers mechanical protection for the cooling components while maintaining a professional look that integrates with most cabinet systems.

Suitable for

• Climate control of wall-mounted electrical enclosures and control cabinets
• Cooling of small to medium server racks and IT equipment in cabinets
• Industrial enclosures where a built-in, space-saving cooling solution is required

When it may not be suitable

This built-in cooling unit is intended for installation into enclosures and may not be suitable where a standalone or free-standing air-conditioning unit is required. It is specified with an input power of 1050 W and a manufacturer-indicated maximum cooling capacity up to 3000 W; larger heat loads beyond the stated maximum may require a higher-capacity or multiple-unit solution.

Key specifications

• Input power: 1050 W
• Input voltage range: 110–480 V
• Frequency: 50/60 Hz
• Housing material: steel
• Housing colour: grey
• Maximum cooling capacity (manufacturer listed): up to 3000 W
• Mounting type: built-in / wall-mounted for cabinet integration

How to use

Install the Rittal SK 3312810 into the designated cutout of the enclosure wall following the cabinet manufacturer’s mounting guidelines and local electrical codes. Connect the unit to the available supply within the rated input voltage range (110–480 V) and ensure correct frequency selection or compatibility for 50 Hz or 60 Hz operation. After mechanical and electrical installation, configure any available control interfaces and verify airflow directions, sealing and proper return paths for hot air to avoid recirculation. Regular inspections of filters and heat-exchange surfaces will help maintain performance.

What to consider before purchase

• Match the unit’s cooling capacity to the actual heat load of the enclosure and equipment.
• Verify the available supply voltage and frequency at the installation site falls within 110–480 V and 50/60 Hz.
• Ensure the cabinet has the correct cutout and mounting provisions for a built-in/wall-mounted unit and sufficient clearance for airflow and maintenance.
• Consider whether additional ventilation, ducting or multiple units are needed for larger enclosures or concentrated heat sources.

Usage recommendations

Use the built-in cooling unit as part of a coordinated cabinet thermal management strategy: size the unit to the measured heat load, maintain intake and exhaust paths, and schedule periodic maintenance of filters and heat-exchange surfaces to preserve cooling performance and energy efficiency.
