Hi-tech dual discharge industrial air coolers with radial fans
Versatility engineered for every cold room
Defender CRD
Defender CRD
Defender CRD delivers ultra-low noise and versatile performance for occupied cold rooms, where worker comfort matters.
Designed for HFC, CO₂ and brine, it features hinged radial EC fans (630 mm) for minimal noise, low charge, and superior sustainability.
The Defender CRD platform provides a wide selection of configurations and extensive options, empowering you to choose the ideal model tailored precisely to your needs.
Consultant
Defender CRD models provide versatile dual-discharge configurations for precise industrial cold room designs across HFC, CO₂, and brine. Comprehensive documentation – including drawings, wiring diagrams and selection software – supports accurate calculations. Multiple fin spacings (4.5-10 mm), defrost options, hinged radial EC fans and multiple coil configurations enable tailored flexibility.
System Integrator
Defender’s CRD’s modular design with 1-4 radial EC fans (630 mm) simplifies integration into noise-sensitive 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 wired isolator switches reduce onsite commissioning time across all refrigerant types.
General Contractor
Defender CRD 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 fan access for minimized onsite work and quick commissioning.
