Hi-tech dual discharge industrial air coolers
Versatility engineered for every cold room
Defender CD
Defender CD
Defender delivers versatile performance for industrial cooling and freezing applications in medium/large cold rooms.
Designed for multi-refrigerant flexibility (HFC, ammonia, CO₂ and brine), it offers low noise, low refrigerant charge, and superior efficiency with axial fans.
The Defender CD platform provides a wide selection of configurations and extensive options, empowering you to choose the ideal model tailored precisely to your needs.
Consultant
Defender CD models provide Eurovent-certified performance and versatile dual-discharge 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 (4.5-10 mm), defrost options, fan sizes and coil configurations enable tailored flexibility for any application.
System Integrator
Defender’s modular design with 1-4 fans (450-630 mm AC/EC) simplifies integration into diverse cold room systems. Low-profile footprint and customizable connections (top connections for brine units) fit tight ceiling spaces while maintaining uniform airflow coverage. Pre-assembled options like insulated drain trays and hinged access reduce onsite commissioning time across all refrigerant types.
General Contractor
Defender CD offers fast ceiling installation with pre-tested, leak-charged units and transport-optimized packaging for medium/large cold rooms. Low-profile design maximizes usable cold room height; robust epoxy RAL9003 casing withstands industrial environments. Hinged components and mounting brackets minimize onsite work and ensure quick commissioning.
