SK3311.430 Rittal LCP Inline DX WHD: 300x2000x1200mm 12 kW flush 380-480 V 3~ 50/60 Hz

Why Choose the Rittal SK3311.430 LCP Inline DX?

The Rittal SK3311.430 LCP Inline DX is a high-performance refrigerant-based split cooling system for IT rack rows, designed for efficient thermal management of small and medium-sized data centre installations. Delivering up to 12 kW cooling output, the unit is installed alongside compatible server racks and supports the front-to-back airflow principle used by modern 482.6 mm (19") IT equipment.

The LCP Inline DX draws warm server exhaust air from the rear aisle, cools it through its integrated air/refrigerant heat exchanger and returns conditioned air to the room or cold aisle. Its inverter-controlled compressor continuously adapts cooling output between approximately 3–12 kW according to actual demand, while four efficient EC fan modules provide up to 4,800 m³/h of unimpeded airflow at 50 Hz.

Designed for flush installation within a bayed TS IT enclosure suite, the SK3311.430 measures 300 mm wide × 2000 mm high × 1000 mm deep. It operates from a 400 V three-phase 50 Hz supply or 380–480 V three-phase 60 Hz supply and provides IP20 protection. An external condenser is required to complete the refrigerant circuit and reject absorbed thermal energy outside the installation room.

• Supports integration into Rittal IT monitoring infrastructure.

Precision Row Cooling for IT Infrastructure

High-density servers and network equipment generate concentrated heat loads that require controlled cooling directly alongside the rack row. The Rittal LCP Inline DX uses front-to-back airflow, drawing heated air from the rear of the IT equipment and returning cooled air towards the cold aisle. This targeted approach helps minimise unwanted mixing between hot and cold air while maintaining suitable server inlet temperatures.

The SK3311.430 combines four EC fans with an inverter-controlled compressor to adapt cooling performance continuously to actual IT demand. Because the cooling unit is physically separated from the server enclosures, maintenance can be performed without unnecessarily disturbing installed IT equipment. The split-system design transfers absorbed heat to an external condenser, preventing that thermal energy from being released back into the data centre room.

Typical Applications

• Small and medium-sized data centres.
• Server rooms and edge computing installations.
• High-density IT rack cooling.
• Rittal TS IT enclosure suites.
• Hot aisle and cold aisle data centre configurations.
• Enterprise server and storage infrastructure.
• Network and telecommunications equipment rooms.
• IT installations requiring dedicated row-based cooling.
