Rack cooling unit Rittal 3374.140 — 169 W input power, 0.1111111111 l/s airflow, White, built-in display

Rittal 3374.140 is a rack cooling unit designed for enclosures and server cabinets where controlled heat removal and stable internal temperatures are required. The unit provides 169 W input power and an airflow of 0.1111111111 l/s, and includes a built-in display for local monitoring. It is intended for 400 V, 50/60 Hz supply and comes in a white housing suitable for installation in industrial or IT cabinets. The product belongs to a family of air/water heat exchanger solutions with versatile mounting options and is suitable for environments with elevated ambient temperatures.

Advantages

The built-in display enables on-site monitoring of operating status and temperature information without additional instruments. Compact dimensions and a design compatible with rack mounting make the unit straightforward to integrate into server and control cabinets. The unit is rated for 400 V, 50/60 Hz operation and its white housing supports a neutral appearance within technical environments. As part of Rittal air/water heat exchanger product family, it benefits from proven concepts for external or internal mounting and flexible water connection possibilities.

Suitable for

• Cooling of small to medium sized server cabinets and network racks
• Temperature control of electrical enclosures and control cabinets
• Heat removal in industrial cabinets where a compact, display-equipped unit is required
• Installations that use 400 V, 50/60 Hz mains supply

When it may not be suitable

The unit’s input power of 169 W and airflow of 0.1111111111 l/s indicate it is intended for modest cooling loads; it may not be appropriate for enclosures with high heat dissipation requirements or dense server installations that demand kilowatt-class cooling. Systems requiring integrated refrigerant compressors or extreme low-temperature control will need different cooling technologies.

Key specifications

• Airflow: 0.1111111111 l/s
• Supply voltage: 400 V, 50/60 Hz
• Housing colour: White
• Interface: Built-in display for local monitoring
• Mounting options: Suitable for rack/enclosure installation; supports external or internal mounting as per heat exchanger family features

How to use

Install the cooling unit in the designated rack or enclosure area following cabinet layout and ventilation requirements. Connect the unit to a 400 V, 50/60 Hz supply and to the building or system water circuit if used in an air/water heat exchange configuration, observing hydraulic connection guidance and sealing requirements. Use the built-in display to verify operating status and temperature readings during commissioning. Monitor the unit periodically for airflow obstructions, water connection integrity and normal display indications.

What to consider before purchase

• Required cooling capacity of the cabinet compared to the unit’s 169 W input power
• Compatibility with 400 V, 50/60 Hz electrical supply
• Availability and routing of water connections if used as part of an air/water heat exchanger system
• Physical space and mounting orientation within the target enclosure or rack

Usage recommendations

For reliable performance, size the cooling solution to exceed the estimated heat load of the enclosure, ensure correct hydraulic and electrical connections, and maintain free airflow paths. Use the built-in display during setup to confirm setpoints and monitoring parameters, and schedule regular inspections of water connections and filter or airflow paths.
