Built-in cooling unit Rittal SK 3307700 — 1300 W input, 1550 W cooling, 230 V, stainless steel, grey

The Rittal SK 3307700 built-in cooling unit is designed for thermal management of electrical enclosures, control cabinets and small server racks. With an input power of 1300 W and a rated cooling capacity up to 1550 W at 230 V, 50/60 Hz, this stainless steel, grey-finished module provides continuous cooling performance suitable for industrial environments. The unit is part of the modular "Blue e" climate control concept and is intended for integration into climate control doors and enclosures where space-saving, reliable cooling is required.

Advantages

This cooling unit delivers a high cooling capacity relative to its input power, providing efficient removal of heat from electronics and control components. Its stainless steel construction and grey finish offer resistance to corrosion and a durable exterior suitable for harsh or humid environments. The module is compatible with the Blue e family, allowing modular system integration and the possibility to connect to an IoT interface with the appropriate adaptor and controller for remote monitoring and control.

Suitable for

• Cooling electrical enclosures and control cabinets in industrial settings
• Maintaining temperature in small server racks and communications cabinets
• Applications requiring a stainless steel cabinet-mounted cooling solution
• Integration into climate control doors as part of a modular cooling concept

When it may not be suitable

This unit is intended for built-in installation in compatible cabinets and climate control doors; it may not be appropriate where only standalone or portable cooling is required. For installations that require cooling capacities significantly above 1550 W, larger modules from the Blue e range with higher total cooling output should be considered.

Key specifications

• Rated cooling capacity: up to 1550 W
• Input power: 1300 W
• Supply voltage and frequency: 230 V, 50/60 Hz
• Construction material: stainless steel
• Finish: grey
• Intended mounting: built-in for climate control doors and enclosures
• Modular concept compatibility: Blue e cooling module family

How to use

Install the unit according to the enclosure manufacturer's instructions for built-in cooling modules, ensuring proper cutouts, sealing and mechanical fastening. Connect the supply to a 230 V, 50/60 Hz source via appropriate electrical protection and comply with local wiring regulations. Position airflow paths so that conditioned air is directed over heat-generating components and exhaust can be routed safely away from the cabinet. Regular maintenance includes cleaning air paths, inspecting seals and verifying electrical connections and controller settings.

What to consider before purchase

• Verify that the cabinet or climate control door supports built-in installation and fits the module dimensions
• Confirm that the required cooling capacity (up to 1550 W) matches the heat dissipation of installed equipment
• Ensure electrical supply is 230 V, 50/60 Hz and that protection devices are sized correctly
• Consider environmental conditions and whether stainless steel construction is required for corrosion resistance

Usage recommendations

For reliable operation, maintain clear intake and exhaust paths, schedule periodic inspections and, if remote monitoring or integration is needed, use the Blue e IoT adaptor and compatible e-Comfort controller where applicable. Select a module from the Blue e series with an appropriate total cooling output if higher capacity or linking to larger systems is required.
