Product information
The YAKE Desiccant Dehumidifier RY-400M is engineered for demanding commercial environments requiring extremely low humidity levels or precise dew point control. This robust unit excels in both very cold and hot conditions, operating reliably across temperatures from -20°C to +50°C with a dehumidification capacity of 2.50 kg/hr at standard conditions.
Key Features
- Precision CNC-machined construction with optimised silica gel wheel for maximum water vapour absorption efficiency
- Operates reliably in extreme temperatures from -20°C to +50°C with advanced noise damping and shock absorption
- Comprehensive electrical protection including circuit breakers and leakage safeguards for motor, heater and drive components
- Industrial-grade flange design with unique sealing system to minimise air leakage and ensure stable operation
- IP44 protection rating and EN60204 compliant electrical design for safe industrial operation
Typical Applications
Ideal for industrial facilities, cold storage warehouses, manufacturing plants and commercial spaces requiring precise humidity control in extreme temperature environments. The unit’s ability to achieve extremely low humidity levels makes it suitable for sensitive storage applications and processes demanding strict moisture control.
RY400M is suitable for very cold or hot areas or areas requiring extremely low humidity percentage or dew point. When you choose this desiccant dehumidifier, you can buy and install with confidence.
The desiccant wheel itself is made of quality silica gel material, which is very good at absorbing water vapour.
The air flow, wheel transmission and wheel rotation speed are optimized by technicians during manufacture. This cutting edge technology is used to ensure maximum efficiency of air distribution, air balance and dehumidifying capacity.
