FRAL Refrigerant Dehumidifier FD520

The FRAL Refrigerant Dehumidifier FD520 is a commercial-grade humidity control solution designed for demanding industrial and commercial environments. With optional sub-zero operation capability and robust construction, this unit is engineered for warehouses, indoor heated swimming pools, commercial agricultural sheds, growing rooms, electronic control rooms, and mining facility management operations.

Key Features

• Optional sub-zero temperature operation with hot gas defrosting system for reliable performance in cold environments
• Scroll compressor technology with comprehensive high and low pressure protection switches for enhanced reliability
• Durable aluminium pipe frame construction with galvanised and painted steel panels for long-lasting commercial use
• Three-speed fan operation and automatic humidistat control (or remote control option) for precise humidity management
• Continuous drainage pipe connection fittings with available double version configurations for flexible installation

Typical Applications

This dehumidifier is ideal for commercial and industrial facilities including warehouses, indoor heated swimming pools, agricultural sheds, growing rooms, electronic control rooms, and mining operations. The unit’s robust design and optional sub-zero operation make it particularly suitable for challenging environments requiring reliable humidity control.

Nearly alike in looks to their big brothers FRAL FD750 and FD980, commercial dehumidifiers are used in similar areas: warehouses, indoor heated swimming pools, commercial agricultural sheds or growing rooms, electronic control rooms, managing facilities in mining operations and other areas requiring dehumidification. These units also come with a smaller price tag and weigh a little less but are of course built to the same exacting standards as all FRAL dehumidifiers.
