Why Choose the Rittal SK 3313.450 LCP Inline DX?
The Rittal SK 3313.450 is a high-performance Liquid Cooling Package LCP Inline DX designed for precise and energy-efficient cooling of small and medium-sized IT environments. As part of the advanced Rittal LCP Inline DX series, it is engineered for installation alongside server racks within a bayed enclosure suite, providing targeted cooling directly where heat is generated.
The LCP Inline DX uses a direct-expansion split cooling system with an inverter-controlled compressor and three EC fan modules. Cooling output is continuously adapted to actual demand across a modulation range of 8–35 kW, helping improve temperature stability and reduce unnecessary energy consumption during partial-load operation. Integrated temperature monitoring and redundant air-side temperature sensing further support dependable IT operation.
With a maximum cooling output of 35 kW, a three-phase 380–480 V AC supply and compact dimensions of 600 × 2000 × 1000 mm (W × H × D), the SK 3313.450 is designed for high-density rack cooling without requiring a large footprint. Hot air is drawn from the rear aisle, cooled inside the unit and delivered back towards the room or cold aisle, while absorbed heat is rejected through a separately installed external condenser.

Precise Direct-Expansion Cooling for IT Infrastructure
The Rittal LCP Inline DX cooling principle places cooling capacity directly alongside the IT racks that generate the heat. Warm server exhaust air is drawn into the rear of the unit, passed across the evaporator and then returned as cooled air towards the room or cold aisle. This supports effective front-to-back airflow through 482.6 mm (19-inch) server installations while reducing the distance cooled air must travel.
An inverter-controlled compressor and EC fan modules continuously adjust cooling performance to match actual thermal demand. Absorbed heat is transported through the refrigerant circuit to a remote external condenser, allowing heat to be rejected outside the IT room rather than adding to the thermal load within the installation area.
Typical Applications
- Small and medium-sized data centres.
- High-density server rack cooling.
- Cooling of one or two IT racks.
- Server rooms and network equipment rooms.
- Edge computing and distributed IT installations.
- VX IT rack and enclosure systems.
- IT environments requiring network-monitored precision cooling.
