Rack cooling unit Rittal 3375.540, 183 W input power, 0.1111111111 l/s airflow, black/white

Rittal 3375.540 is a rack-mounted cooling unit designed to stabilise temperature inside server racks, control cabinets and electronic enclosures. The unit provides 183 W input power and operates from a 400 V, 50–60 Hz supply. It delivers an airflow of 0.1111111111 l/s and is available in black or white. A built-in display allows basic monitoring of operating status and temperature-related parameters. The product is intended for enclosure climate control where compact, rack-integrated cooling is required.

Advantages

The Rittal 3375.540 offers compact rack-mounted cooling with a clear front display for status monitoring and simple integration into existing cabinet layouts. Its fixed airflow and rated input power make it suitable for maintaining set temperatures in small to medium enclosures. Dual-colour options (black/white) support visual matching with different cabinet designs, while compatibility with standard 400 V, 50–60 Hz supplies simplifies electrical connection in industrial and IT environments.

Suitable for

• Cooling server racks and network cabinets with moderate heat loads
• Control cabinets and automation enclosures requiring stable internal temperature
• Electronic equipment housings in industrial settings with available 400 V supply
• Retrofit projects where a rack-mounted cooling unit with a small footprint is needed

When it may not be suitable

This unit is rated for 183 W input power and limited airflow; it may not be sufficient for large enclosures or systems with high heat dissipation requirements. For applications that demand higher cooling capacities, greater airflow, or liquid-cooling loops beyond the unit's design limits, a higher-capacity heat exchanger or an alternative cooling system should be considered.

• Airflow: 0.1111111111 l/s
• Mounting: rack-mounted (designed for integration into cabinets and racks)
• Colour options: black and white
• Built-in display: yes (for monitoring operating status)
• Operating ambient capability: suitable for use in demanding environments and elevated temperatures when installed per manufacturer guidance

How to use

Install the Rittal 3375.540 into an appropriate rack or cabinet opening following the manufacturer's mounting instructions and ensuring secure mechanical attachment. Connect the unit to a compatible 400 V, 50–60 Hz electrical supply using proper wiring and protective devices. Position airflow paths to avoid obstruction and to support effective heat extraction from the enclosed components. Use the built-in display to check status and basic parameters; refer to the official manual for configuration, maintenance intervals, filter cleaning or replacement procedures, and fault indications.

What to consider before purchase

• Confirm the enclosure heat load to ensure 183 W input power and 0.1111111111 l/s airflow meet cooling needs
• Verify availability of a 400 V, 50–60 Hz supply and appropriate electrical protection
• Check cabinet dimensions and mounting cutouts to ensure compatibility with a rack-mounted unit
• Decide on colour (black or white) if visual matching with existing equipment matters
• Assess environmental conditions and temperature ranges to confirm the unit is suitable for the installation site

Usage recommendations

For reliable operation, maintain clear airflow paths, perform periodic display and filter checks, and follow the manufacturer's installation and maintenance instructions. If enclosure heat dissipation increases over time, reassess cooling capacity and consider higher-output solutions or supplemental ventilation.
