Rack cooling unit Rittal 3304.504 — 890 W input power, 230 V, 50/60 Hz, steel housing, grey

Rittal 3304.504 is a rack cooling unit engineered for precise enclosure climate control. The unit provides 890 W input power at 230 V, 50/60 Hz, and comes in a grey steel housing with an integrated display for monitoring and basic control. Designed for use in electrical cabinets, server racks and industrial control enclosures, this cooling solution supports elevated cooling loads and offers stable temperature regulation in compact form factor.

Advantages

This rack cooling unit combines a robust steel housing with a built-in display and standard mains compatibility (230 V, 50/60 Hz), enabling straightforward integration into existing installations. The unit’s high rated input power and manufacturer-specified peak cooling capability allow it to handle heat generated by densely packed electronics. Its design supports mounting on racks and cabinets where reliable, continuous cooling and straightforward monitoring are required.

Suitable for

• Electrical distribution cabinets and control panels where active heat removal is needed
• Server racks and network enclosures with moderate to high internal heat loads
• Industrial automation cabinets and PLC enclosures subject to continuous operation

When it may not be suitable

This model may not be suitable for applications that demand extremely low noise levels, as industrial rack cooling units typically produce audible fan noise under load. It is also not intended for use where explosion-proof or intrinsically safe equipment is required, or for environments with aggressive chemical vapors that can corrode standard steel housings without additional protective measures.

Key specifications

• Input power: 890 W
• Supply voltage and frequency: 230 V, 50/60 Hz
• Housing material and color: steel, grey
• Built-in display for status and basic control
• Designed mounting: rack/enclosure installation
• Manufacturer-stated peak cooling capability: up to 2500 W (per manufacturer data)

How to use

Mount the cooling unit in the designated opening or on the rack as specified by the enclosure manufacturer and the unit’s installation instructions. Connect the unit to a 230 V, 50/60 Hz mains supply using appropriate wiring and protective devices. Use the integrated display to set the desired temperature or operating mode and monitor performance. Ensure intake and exhaust paths are clear and that filters, where present, are maintained according to the maintenance schedule to preserve cooling efficiency.

What to consider before purchase

• Confirm that the enclosure has the required cut-out or mounting space and supports a steel-housed cooling unit.
• Verify the unit’s cooling capacity is sufficient for the expected heat dissipation of the installed equipment.
• Check electrical compatibility with your installation (230 V, 50/60 Hz) and required protective devices.
• Assess the ambient environment for corrosive agents, humidity, or classification that may require special protection.
• Plan for maintenance access to filters and fans for reliable long-term operation.

Usage recommendations

For stable enclosure climate control, size the cooling unit to exceed the continuous heat load of installed components, allow clearance for airflow, and perform regular filter and fan maintenance. Use the built-in display for periodic checks and integrate the unit into enclosure monitoring where precise alarm handling is required.
