ECOR Pro Desiccant Dehumidifier - model DH3500
$4,500.00
The ECOR PRO DH3500 is a compact, commercial-grade desiccant dehumidifier designed for flood restoration, construction drying, cold rooms, crawl spaces and demanding industrial applications.
Unlike refrigerant dehumidifiers, the DH3500 uses a rotating desiccant rotor to absorb moisture from the air. A PTC heater regenerates the rotor, and the extracted moisture is discharged outside as warm, wet air through an 80mm duct.
Because moisture is vented away rather than collected as liquid water, there is no water tank to empty, gravity drain or condensate pump to monitor.
The DH3500 can operate in multiple orientations—even upside down—and performs effectively in temperatures below freezing. Its four-port system supports pressure-neutral drying in enclosed spaces where maintaining balanced air pressure is important.
Four-Port Drying Technology
The DH3500 can operate in three-port or four-port configurations.
Four-port operation separates both the process and regeneration air streams, enabling pressure-neutral drying. This makes the unit suitable for sealed rooms, drying cabinets, cold rooms, freezers and specialist industrial applications.
- Process-air inlet: 125mm
- Dry-air outlet: 125mm
- Regeneration-air inlet: 80mm
- Wet-air exhaust: 80mm
The desiccant rotor continuously absorbs moisture, while heated regeneration air removes moisture from the rotor and exhausts it outside.
