The Sealey Industrial Dehumidifier 50Ltr tackles serious moisture problems in commercial and industrial settings. This white commercial-grade unit measures 60.5cm x 40cm x 66cm and weighs 31.78kg.
What makes this unit special? It extracts up to 50 litres of moisture daily whilst processing 350 cubic metres of air per hour. The automatic defrost function prevents ice build-up when temperatures drop below optimal levels.
Key features include a washable activated carbon filter for cleaner air and continuous drainage capability. The R407C refrigerant system operates efficiently at temperatures up to 30°C, making it perfect for workshops, warehouses and damp commercial spaces.
With a 50-litre daily extraction capacity and 350 cubic metre per hour air flow, this unit handles large commercial spaces effectively. It's designed for warehouses, workshops, basements and industrial areas rather than domestic rooms. The exact coverage depends on humidity levels, but it typically manages spaces of 100-200 square metres in commercial settings.
The auto-defrost system monitors coil temperature and activates when ice formation is detected. When room temperatures drop below optimal levels, moisture can freeze on the cooling coils, reducing efficiency. The system automatically switches to defrost mode, melting the ice and then resuming normal operation. This prevents damage and maintains consistent moisture removal performance.
Yes, the continuous drainage feature allows unattended operation. You can connect a standard drainage hose to the unit and direct water to a floor drain or external outlet. This eliminates the need to manually empty the 50-litre tank and allows the dehumidifier to run continuously for weeks or months during building drying projects.
The activated carbon filter should be cleaned every 2-4 weeks depending on air quality and usage. Remove the filter, rinse with clean water and allow to dry completely before reinstalling. The washable design saves money compared to disposable filters and maintains air purification performance. Replace the filter only when the carbon material begins to break down after extended use.
The unit operates effectively in temperatures up to 30°C, but performance may reduce in very cold conditions. The automatic defrost function helps maintain operation when temperatures drop, but for consistently cold environments below 5°C, efficiency will be reduced. It's best suited for heated or semi-heated commercial spaces rather than completely unheated outdoor storage areas.
As an industrial-grade unit processing 350 cubic metres per hour, power consumption will be higher than domestic models. Exact wattage isn't specified, but expect similar consumption to other 50-litre commercial dehumidifiers, typically 800-1200 watts during operation. The efficient R407C refrigerant system helps optimise energy use whilst maintaining high extraction rates.
The package includes the complete dehumidifier unit with washable activated carbon filter already installed. You'll need to provide your own drainage hose if using the continuous drainage feature. The unit comes with a one-year warranty covering manufacturing defects and component failures under normal commercial use.
As an industrial dehumidifier with high air flow capacity, it produces more noise than domestic units. The powerful fan and compressor generate operational noise typical of commercial equipment. Noise levels aren't specified, but expect similar sound output to other industrial dehumidifiers - suitable for workshops and commercial spaces but potentially too loud for quiet office environments.
