SK3303.510 Rittal Blue e cooling unit Wall-mounted 0.66 kW 115 V 1~ 60 Hz Sheet steel

Why Choose the Rittal SK 3303.510 Blue e Wall-Mounted Cooling Unit?

The Rittal SK 3303.510 is an energy-efficient Blue e wall-mounted enclosure cooling unit designed to provide reliable climate control for electrical and electronic equipment in industrial enclosures. Operating from a 115 V, single-phase, 60 Hz supply, this compact unit provides up to 0.66 kW total cooling output under its specified L35/L35 operating conditions.

As part of the proven Rittal TopTherm Blue e series, the SK 3303.510 combines efficient refrigeration technology with an e-Comfort controller for precise temperature management. Its condenser features Rittal's hydrophobic RiNano coating, helping reduce dirt adhesion and support dependable operation in industrial environments. Cooling units from this output class can also be connected to the Rittal IoT interface using a compatible Blue e IoT adaptor.

The unit has a compact 280 mm wide × 550 mm high × 210 mm deep sheet-steel housing finished in RAL 7035. Air throughput is 345 m³/h in the external circuit and 280 m³/h in the internal circuit, while protection ratings of IP34 externally and IP54 internally help protect the cooling system and enclosed equipment.

Reliable Cooling for Industrial Enclosures

Electrical and electronic components generate heat during operation, and excessive enclosure temperatures can reduce reliability and shorten component service life. The Rittal SK 3303.510 uses separate internal and external air circuits to remove heat from the enclosure while helping maintain the separation between enclosure air and the surrounding environment.

The e-Comfort controller provides electronic temperature regulation, while the unit's 345 m³/h external and 280 m³/h internal airflow supports effective heat transfer. Its compact wall-mounted design makes the SK 3303.510 particularly suitable for control cabinets and machinery where dependable cooling is required without occupying valuable space inside the enclosure.

Typical Applications

• Industrial electrical control enclosures.
• Automation and PLC control cabinets.
• Machine control systems.
• Manufacturing and production equipment.
• Electrical and electronic equipment requiring active enclosure cooling.
• Industrial installations using a 115 V, 60 Hz electrical supply.
