Outdoor Air Conditioner Unit Rittal SK 3311.360 — 12 kW cooling, 230 V, 50 Hz, white
Rittal SK 3311.360 is an outdoor air conditioner condenser unit designed for external installation in residential and light-commercial settings. Delivering 12 kW of cooling capacity, this cooling-only unit operates on 230 V, 50 Hz and is supplied in a white finish. It is intended to function as the outdoor condenser for refrigerant-based LCP systems (LCP DX) or as a standalone outdoor condenser where a high-capacity cooling source is required. The product supports roof or wall mounting and is available in variants that include an external condenser and fan, with an alternative version providing an additional free cooler for combinations that require LCP DX/FC functionality.
The unit offers a compact, externally mounted condenser solution optimized for refrigerant-based LCPs, providing a clear separation between indoor LCP electronics and the outdoor heat rejection stage. Its 12 kW cooling capacity and 230 V, 50 Hz electrical compatibility make it suitable for standard residential supply. The white finish and wall/roof mounting options enable flexible placement to match site and aesthetic requirements. The availability of a variant with a free cooler allows integration into systems that need periodic free-cooling operation.
This product provides cooling-only functionality and does not include integrated heating, humidification, or dehumidification control beyond the cooling cycle; applications requiring active heating or precise humidity management would need additional equipment. If a site requires indoor-mounted condensers or integrated water-based chillers rather than refrigerant-based outdoor condensers, this unit would not be the appropriate choice.
Install the unit outdoors on a suitable roof or wall structure following local mounting regulations and manufacturer guidance for clearances and secure anchoring. Connect refrigerant lines to the corresponding indoor LCP DX equipment or configure as a standalone condenser with compatible refrigerant circuits. Provide a dedicated 230 V, 50 Hz power supply and ensure electrical connections comply with local codes. Commissioning should include leak testing, refrigerant charge verification, and performance checks at expected ambient conditions. For variants with a free cooler, configure controls to enable free-cooling operation when ambient conditions allow.
Install the condenser where airflow is unobstructed and service access is maintained; schedule professional commissioning and periodic maintenance (cleaning of coils, fan inspection, refrigerant checks) to preserve 12 kW performance and system reliability.
