The E Series delivers affordable, natural evaporation-based humidification in a plug-and-play format, perfect for smaller spaces or budget-conscious upgrades in SMEs across Malaysia’s commercial and industrial ecosystem.


The E Series delivers affordable, natural evaporation-based humidification in a plug-and-play format, perfect for smaller spaces or budget-conscious upgrades in SMEs across Malaysia’s commercial and industrial ecosystem.
Engineered with SU316/304 stainless steel casing and C5-grade corrosion resistance, the E‑Series is designed to thrive in Malaysia’s diverse environments—from coastal facilities to high-humidity industrial zones. With process air handling capacities of 150, 300, and 500 m³/h, these compact units provide powerful dehumidification down to 10% RH, a performance level refrigeration-based systems simply cannot achieve.
Key advantages
- Ultra-low humidity capability: Ensures product integrity in sensitive industries such as food, pharmaceuticals, and precision manufacturing.
- Smart auto-control: Energy-efficient, unmanned operation that adapts to daily load changes.
- Eco-friendly design: High-temperature sterilization (>100℃) without refrigerants, plus maintenance-free operation.
- Compact footprint: Easy installation, space-saving design, and simplified upkeep.
Through Josem’s new partnership in Malaysia, customers benefit from localized service, faster delivery, and tailored support, ensuring that humidity control solutions are not only advanced but also accessible and reliable for the region’s growing industrial and commercial sectors.

E-Series Product Information
- Fan-assisted evaporation pads for silent, drip-free operation.
- Built-in float valve for automatic water refill.
- Portable design with castors for easy relocation.
- Low energy: 50-200W, with optional solar integration.
- Antimicrobial pads prevent bacterial growth.
- Extreme Dehumidification – With rotary technology as the core, the humidity range is controlled at 5-80%, while the ordinary compressor refrigeration dehumidifiers usually have a humidity range of around 45%, which cannot meet the dehumidification requirements of special environmental conditions.
- With silicone runners for adsorption and dehumidification, the operating temperature range of the equipment can be controlled at -20-60℃.
- Accurate and intelligent control – The humidity sensor with Swiss chip is used to provide an accuracy of up to 0.1% for precise humidity control.
- Direct discharge of moisture – The Josem desiccant dehumidifier directly discharges moisture outdoors through pipelines, without affecting the indoor environmental humidity, thereby improving the dehumidification efficiency of the entire machine.
- Small-scale printing and binding operations.
- Art conservation rooms and museums.
- Office environments for employee comfort.
