Ceiling Ducted Dehumidifier

Ceiling Ducted Dehumidifier

Dehumidifying Capacity: 28 ~ 60 liter / day @ 30°C, 80%RH


Our Ceiling Ducted Dehumidifier is designed to help constantly keeping the treated room dry without loss of energy, as the dry air is re-circulated and contained within the room. It is also equipped with 5 stages air purification system, to ensure the air is purified and cleaned. With the combination of Dehumidifying and Air Purifying functions, the ceiling mounted dehumidifier can now introduce fresh air into the room, where it will be kept fresh, dried and purified all day long.

Key Features:

  • The body material of the dehumidifier is made of cold-rolled sheet metal with epoxy powder coating paint
  • Evaporator and Condenser of the dehumidifier is epoxy-coated for better durability and corrosion resistant.
  • Low maintenance cost and energy efficient design dehumidifier.
  • Dehumidifier equipped with reliable and high-performance reciprocating compressor with environmental friendly refrigerant R134A or R410A
  • Energy Saving, High Efficiency AC / EC Centrifugal Fan for low noise, high static pressure operation with variable speed controller is equipped with our dehumidifier.
  • Optional 5-Stages of Air Filtration System (Primary, Secondary, HEPA, Ionizer, UV Sterilizing Lamp) can be built in the dehumidifier.
  • The dehumidifier is built with reliability for long hour operation 24/7.
  • Advance touch button controller with built-in temperature and humidity sensor. It is easy to set up the dehumidifier and settings will be stored in memory.
  • Honeycomb Structure Evaporator with blue coated hydrophilic water-repellent, which provide better efficiency to dehumidify the air
  • Water Drain Pan of the dehumidifier is made of SUS304 stainless steel to prevent corrosion damage.

5 Stages of Filtration System

Our dehumidifier is designed not only to dehumidify, it also equipped with the most essential Air Filtration Technologies, that consists of Primary Filter, Secondary Filter, HEPA (H13) Filter, Ionizer, UV Sterilizing Lamp.
