Built-in Chiller Rittal SK 3334.400 with 5500 W Cooling Capacity, Steel Housing, Built-in Display, 380–415 / 440–480 V, 50/60 Hz

Rittal SK 3334.400 is a built-in chiller engineered for enclosure and cabinet cooling with a nominal cooling capacity of 5500 W. The unit is housed in a grey steel enclosure and includes an integrated display for local status monitoring and control. It accepts three-phase mains input at 380–415 V or 440–480 V and operates at both 50 Hz and 60 Hz, making it compatible with common industrial power systems. The chiller is intended to remove heat from electrical components and maintain stable internal temperatures in control cabinets and switchgear.

Advantages

This built-in chiller delivers a high nominal cooling capacity of 5500 W in a compact, steel-housed unit suitable for direct installation in cabinets. The integrated display provides immediate feedback on operating status and control settings, simplifying commissioning and on-site adjustments. Compatibility with 380–415 V and 440–480 V three-phase supplies at 50/60 Hz ensures flexible deployment across different industrial installations. The steel housing offers mechanical robustness and protection for internal components in typical factory environments.

Suitable for (tasks / use cases)

• Cooling electrical enclosures and control cabinets in industrial facilities
• Temperature regulation for power electronics, drives, and PLC racks
• Heat removal in switchgear, motor control centres and automation cabinets
• Applications requiring a built-in chiller with local display and three-phase power compatibility

When it may not be suitable

The chiller is designed specifically for built-in installation within cabinets; it may not be suitable for standalone room air conditioning or for applications that require portable or free-standing cooling units. Environments with atypical ambient conditions, chemical exposure, or extreme humidity may require additional protective measures or alternative cooling solutions designed for those conditions.

Key specifications

• Nominal cooling capacity: 5500 W
• Housing material and finish: steel, grey
• Integrated local display for status and control
• Input voltage: three-phase 380–415 V or 440–480 V
• Frequency: 50 Hz / 60 Hz
• Intended mounting: built-in installation in cabinets/enclosures

How to use

Install the chiller into the designated recess or mounting location within the cabinet according to the enclosure manufacturer’s cut-out and fixation instructions. Connect the three-phase supply of the correct voltage range and ensure proper grounding and electrical protection are in place. Use the integrated display to configure operating parameters and to monitor temperature and system status during commissioning. Verify airflow paths and ensure that inlet and outlet openings in the cabinet are not obstructed. Regular visual checks and scheduled maintenance according to the manufacturer’s guidelines will help sustain performance.

What to consider before purchase

• Confirm that the cabinet has the correct cut-out dimensions and structural support for a built-in chiller.
• Verify supply voltage and frequency compatibility with site mains (380–415 V or 440–480 V, 50/60 Hz).
• Check that 5500 W nominal cooling capacity meets the heat load and safety margin requirements of your components.
• Ensure that cabinet airflow management and external ventilation meet the chiller’s installation needs.

Usage recommendations

Operate the chiller within the specified voltage and frequency ranges and follow recommended mounting and clearance instructions. Use the integrated display for routine monitoring and configure alarm thresholds to protect sensitive electronics from overheating. Schedule periodic maintenance, including filter and condenser inspections, to preserve cooling efficiency and prolong service life.
