Rittal SK 3304.508 Built-in cooling unit, 1100 W, 230 V, 50/60 Hz, grey steel housing

The Rittal SK 3304.508 built-in cooling unit is a purpose-made cooling solution for control cabinets and electrical enclosures. With 1100 W cooling capacity and operation on 230 V at 50/60 Hz, this unit is intended to maintain stable internal temperatures for sensitive electronic and electrical components. The unit is housed in a grey steel casing designed for integration into cabinet walls and provides consistent performance for industrial and commercial cabinet cooling applications.

Advantages

The cooling unit offers a balance of power and compact installation form factor, delivering 1100 W of cooling in a built-in configuration suited for cabinet integration. Its steel housing provides mechanical protection and supports reliable long-term operation in machine rooms and electrical rooms. The unit's compatibility with 230 V mains and 50/60 Hz frequency ensures straightforward electrical connection in many regional installations.

Suitable for

• Cooling control cabinets and switchgear with moderate heat loads
• Industrial enclosures containing PLCs, drives, and power electronics
• Wall-mounted or panel-integrated cabinet installations requiring a built-in cooling solution
• Applications where a robust steel housing and standard mains compatibility are required

When it may not be suitable

This built-in unit is designed for cabinet integration and may not be suitable for free-standing room cooling or for enclosures that require very high cooling capacities beyond 1100 W. It is also not intended for use in environments that demand specialised corrosion-resistant housings or non-standard voltages/frequencies without appropriate adaptation.

Key specifications

• Cooling capacity: 1100 W (rated input cooling performance)
• Supply voltage: 230 V
• Frequency: 50/60 Hz
• Mounting: built-in / panel-integrated for control cabinets
• Housing material and color: grey steel housing
• Application: cabinet and enclosure temperature control for electrical/electronic components

How to use

Install the unit into the dedicated cut-out or mounting position in the cabinet wall according to enclosure dimensions and mounting instructions from the cabinet or system documentation. Connect the electrical supply to a 230 V, 50/60 Hz circuit following local electrical codes and ensure proper earthing. Configure airflow paths inside the cabinet to allow intake and exhaust without obstruction and position heat-generating components to optimise cooled airflow. Perform initial functional checks and monitor internal cabinet temperatures to confirm the unit achieves the required thermal conditions.

What to consider before purchase

• Verify that a 1100 W cooling capacity is adequate for the total heat dissipation of equipment inside the cabinet
• Confirm cabinet cut-out dimensions and mounting compatibility for built-in installation
• Ensure availability of a 230 V, 50/60 Hz supply and proper grounding at the installation site
• Check whether the grey steel housing meets the environmental and corrosion resistance requirements of the intended location

Usage recommendations

Operate the cooling unit with regular maintenance intervals: keep air passages clear, inspect seals and filters if present, and verify electrical connections. Monitor cabinet temperatures after installation to ensure setpoints are maintained and adjust internal component layout or add supplementary ventilation if hotspots are observed.
