Rack cooling unit Rittal 3378.300 — 350 W input power, 0.5556 l/s airflow, 230 V, 50/60 Hz

Rittal 3378.300 is a rack-mounted cooling unit designed to control the climate inside IT and industrial enclosures. The unit provides 350 W input power and an airflow rate of 0.5556 l/s, operating from a 230 V supply at 50/60 Hz. Available in black and white finishes, this model is intended to stabilise internal temperatures and remove heat from electronic components in cabinets and racks.

Advantages

The Rittal 3378.300 combines compact mounting for standard racks with a specified airflow and power input to maintain predictable heat removal. Its compatibility with 230 V, 50/60 Hz power systems makes it suitable for common electrical environments. The product is available in two colour options to match rack aesthetics and can be integrated into existing enclosure layouts to support continuous operation of sensitive electronics.

Suitable for

• Cooling and temperature stabilisation of server racks and IT cabinets
• Localised climate control in industrial control cabinets and automation enclosures
• Environments where compact, rack-mounted cooling is required without external chillers

When it may not be suitable

This unit is specified with a 350 W input power and relatively low airflow (0.5556 l/s), so it may not be suitable for cabinets with very high heat loads or large data centre racks that require higher-capacity cooling systems. It is designed for rack-mount installation; applications requiring freestanding room air conditioning or liquid-based direct cooling beyond the unit's specifications will need alternate solutions.

Key specifications

• Input power: 350 W
• Airflow: 0.5556 l/s
• Supply voltage: 230 V
• Frequency: 50/60 Hz
• Mounting: rack-mounted for enclosure integration
• Available finishes: black, white

How to use

Install the cooling unit in the designated rack or cabinet opening according to the enclosure manufacturer’s mounting instructions. Connect the unit to a 230 V, 50/60 Hz electrical supply following local electrical codes and ensure proper earthing. Position the unit to allow unobstructed airflow through the enclosure and route cabling to avoid blocking air inlets or outlets. Perform initial functional checks to confirm the fan operation and monitor internal cabinet temperature during the first hours of operation to verify performance.

What to consider before purchase

• Assess the total heat load of the rack to ensure 350 W input power and 0.5556 l/s airflow are adequate
• Verify mounting compatibility with your rack or enclosure dimensions and cutout requirements
• Confirm availability of a 230 V, 50/60 Hz power source and compliance with local electrical standards
• Decide on colour preference (black or white) to match cabinet aesthetics

Usage recommendations

For reliable operation, maintain regular inspection of air inlets and outlets and keep the enclosure free of dust build-up. Use this unit for moderate heat loads in single racks or small clusters and combine with appropriate ventilation or zoned cooling strategies when managing higher-density equipment.
