SK3311.440 Rittal LCP Inline DX WHD: 300x2000x1200mm 12 kW flush 380-480 V 3~ 50/60 Hz

Why Choose the Rittal SK3311.440 LCP Inline DX?

The Rittal SK3311.440 LCP Inline DX is a high-performance direct-expansion row cooling system for IT infrastructure, designed to provide targeted thermal management alongside server and network racks. With up to 12 kW cooling output, it is particularly suited to small and medium-sized data centres where concentrated heat loads require controlled cooling close to the installed IT equipment.

The LCP Inline DX operates using a refrigerant-based split cooling principle, drawing warm exhaust air from the hot aisle, cooling it and supplying conditioned air towards the cold aisle and equipment intakes. Demand-based cooling control helps match cooling performance to the actual IT heat load, supporting efficient operation while maintaining stable environmental conditions for sensitive servers, storage systems and networking hardware.

Designed for flush integration within a compatible Rittal IT enclosure suite, the SK3311.440 measures 300 mm wide × 2000 mm high × 1200 mm deep. The 1200 mm depth aligns with deep server rack configurations, while its 380–480 V AC three-phase, 50/60 Hz supply and IP20 protection rating make it suitable for professional indoor data centre installations.

Key Advantages

• High-performance 12 kW row-based IT cooling system.
• Direct-expansion refrigeration technology provides targeted cooling close to the IT equipment.
• Flush installation supports seamless integration into compatible Rittal rack rows.
• 1200 mm depth complements deep server enclosure configurations.
• 380–480 V AC three-phase, 50/60 Hz operation for industrial and data centre power systems.
• Supports separation of hot exhaust and conditioned supply air.
• Cooling infrastructure remains separate from the IT racks, supporting convenient maintenance access.
• Designed to support efficient thermal management of concentrated server and network equipment heat loads.

Precision Row Cooling for Data Centre Infrastructure

Modern servers, storage arrays and network equipment can generate concentrated heat loads that are difficult to manage using room-level cooling alone. Inline cooling places the cooling system directly within the rack row, allowing warm exhaust air to be captured close to its source and conditioned air to be supplied where the IT equipment requires it.

The Rittal SK3311.440 uses a direct-expansion refrigeration system to transfer heat from the data centre to an external condenser. Its 12 kW cooling capacity and 1200 mm rack-aligned depth make it a practical solution for deep IT enclosure rows, helping reduce unwanted hot and cold air mixing while supporting predictable inlet temperatures and reliable operation of critical computing infrastructure.

Typical Applications

• Small and medium-sized data centres.
• Server rooms and dedicated IT facilities.
• High-density server rack installations.
• Deep 1200 mm IT enclosure configurations.
• Hot aisle and cold aisle arrangements.
• Enterprise computing and storage infrastructure.
• Network and telecommunications equipment rooms.
• Edge computing facilities.
• Rack rows requiring dedicated inline cooling.
