Rack cooling unit Rittal 3178.801, 300 W, 110–240 V, steel housing, grey

Rittal 3178.801 is a rack cooling unit designed for installation in server, network and industrial enclosures. Delivering 300 W of cooling power and accepting a wide-range input voltage of 110–240 V at 50/60 Hz, this cooling unit is housed in a grey steel enclosure and provides active temperature control for cabinets where compact, electrical cooling is required. The unit is intended for systems without condensate management and focuses on keeping internal temperatures within operational limits.

Advantages

The Rittal 3178.801 offers stable 300 W cooling capacity across a broad input voltage range, which enables use in varied electrical environments. Built with a steel housing, it provides mechanical robustness and protection for internal components. Its compatibility with 50/60 Hz mains frequency allows international deployment, while the rack-mounted form factor supports straightforward integration into standard enclosures. The design emphasizes continuous active cooling suitable for electronic equipment that requires reliable thermal control.

Suitable for

• Cooling small to medium-sized server and network cabinets
• Maintaining safe operating temperatures for industrial control cabinets
• Applications where a compact 300 W rack-mounted cooling solution is needed
• Installations with 110–240 V mains supply at 50/60 Hz

When it may not be suitable

This unit is not intended for enclosures that require condensate management; it should not be used where active condensate removal or draining is necessary. For larger cabinets or environments with high heat loads exceeding 300 W, a higher-capacity cooling solution should be selected. Also, if a non-metallic or aesthetic casing is required, the steel housing of this model may not meet those needs.

Key specifications

• Cooling capacity: 300 W
• Input voltage: 110–240 V
• Frequency: 50/60 Hz
• Housing material: steel
• Color: grey
• Mounting type: rack-mounted / enclosure-mounted
• Application: active cooling for cabinets without condensate management

How to use

Mount the cooling unit in the designated rack or enclosure opening according to the cabinet manufacturer’s guidelines. Connect the unit to a compatible 110–240 V, 50/60 Hz mains supply following local electrical codes and ensure proper grounding. Configure any integrated controls or thermostats if present to the desired target temperature range. Verify airflow paths within the cabinet are unobstructed and maintain at least the minimum clearances recommended by the enclosure manufacturer. Regular visual inspection and basic cleaning of air inlets and filters will help maintain performance.

What to consider before purchase

• Required cooling capacity relative to the total heat dissipation of installed equipment
• Whether the enclosure requires condensate management or a drip tray
• Compatibility with cabinet mounting cutouts and available installation space
• Electrical supply availability (110–240 V, 50/60 Hz) and grounding provisions

Usage recommendations

For reliable operation, size the cooling unit for the total cabinet heat load with a safety margin, maintain clear airflow paths, and perform periodic checks of the unit and enclosure ventilation. Avoid installing the unit in environments where condensation can accumulate inside the cabinet.
