Defender CS, LS, ECS
Defender CS, LS, ECS
Defender deliver versatile performance for industrial cold room and data center cooling applications.
Designed for multi-refrigerant flexibility, they meet demanding needs of low-moisture storage (CS), high-humidity/freezing (LS) and CO₂-optimized cooling (ECS) with superior efficiency and durability.
The Defender platform offers a wide selection of cooler configurations and an extensive options list, empowering you to choose the ideal model tailored precisely to your needs.
Consultant
Defender CS, LS and ECS models provide Eurovent-certified performance and versatile configurations for precise industrial cold room designs across HFC, ammonia, CO₂, and brine. Comprehensive documentation – including drawings, wiring diagrams and selection software – supports accurate calculations. Multiple fin spacings (4.5-12 mm), defrost options, fan sizes and coil configurations enable tailored flexibility for any application.
System Integrator
Defender’s modular design with 1-4 fans (450-950 mm AC/EC) and ceiling/floor mounting simplifies integration into diverse cold room systems. Wide refrigerant compatibility (up to 85 bar CO₂ for ECS) and pre-assembled options like insulated drain trays reduce onsite time. Compact footprints and customizable connections (DX, pumped ammonia, brine) match exact project requirements efficiently.
