## Summary description

Rittal 3304.544 is a rack-mounted cooling unit delivering 900 W cooling power for control cabinets and server racks. Designed with a steel grey housing and built-in display, it operates on 400–460 V at 50/60 Hz. Suitable for temperature control in electrical enclosures, industrial switchgear and IT cabinets where reliable heat dissipation is required.

## Long description

Rittal 3304.544 is a rack-mounted cooling unit designed to provide 900 W of cooling power for control cabinets, electrical enclosures and server racks. Housed in a grey steel casing with an integrated display for monitoring and basic control, this cooling unit runs on 400–460 V at 50/60 Hz and is intended to maintain stable internal temperatures where continuous heat dissipation is required. The unit’s mounting style and compact footprint allow installation at cabinet tops or rear panels depending on the rack layout and available space.
Advantages
The cooling unit delivers a rated cooling capacity of 900 W to reliably reduce ambient temperatures inside electrical and IT cabinets. The steel housing offers mechanical robustness and durability in industrial environments while the built-in display provides immediate visibility of operating status and setpoint information. Operation on a 400–460 V supply and dual-frequency support (50/60 Hz) enables compatibility with common industrial power systems.
Suitable for
Control cabinets and switchgear requiring active temperature control
Server racks and IT enclosures with moderate heat loads
Industrial panels where a robust steel housing is preferred
Installations powered from 400–460 V, 50/60 Hz mains
When it may not be suitable
This unit is sized for a 900 W cooling demand; installations with significantly higher heat loads will require larger or multiple units. It is not intended for applications needing precise climate control or humidity regulation beyond basic temperature management. Environments that require non-metallic or corrosion-resistant housings may need an alternative model with appropriate enclosure materials or coatings.
Key specifications
Cooling capacity: 900 W (rated)
Supply voltage: 400–460 V
Frequency: 50/60 Hz
Housing material: steel, grey finish
Mounting: rack/cabinet-mounted (top or rear depending on configuration)
Display: built-in display for status and setpoint viewing
How to use
Install the cooling unit in the designated mounting position on the cabinet or rack following the manufacturer’s mechanical and electrical instructions. Connect the unit to a compatible 400–460 V, 50/60 Hz mains supply and configure basic settings via the integrated display, setting the desired temperature setpoint. Verify airflow paths within the cabinet are unobstructed and that fans or vents in the enclosure allow for efficient heat exchange. Perform initial functional checks to confirm the unit starts, the display reports operating status, and the cabinet temperature responds to the setpoint adjustments.
What to consider before purchase
Confirm the required cooling capacity for your cabinet to ensure 900 W is sufficient
Verify available supply voltage and frequency (400–460 V, 50/60 Hz compatibility)
Check cabinet dimensions and mounting options for correct mechanical fit
Assess environmental conditions for corrosion, dust or moisture that may affect the steel housing
Usage recommendations
For effective temperature control, combine the cooling unit with proper airflow management inside the cabinet (cable routing, blanking panels, and directed ventilation). Schedule periodic inspection of filters, airflow paths and electrical connections to maintain performance and extend service life.
