Fral FDK100 - Compact Professional Dehumidifier

The Fral FDK100 dehumidifier is a small professional dehumidifier equipped with a hot gas defrosting system with electronic and thermostatic control. This industrial dehumidifier is designed to control and maintain humidity even in harsh environments down to temperatures close to 0°C.

Thanks to its smaller size compared to traditional dehumidifiers, the Fral FDK100 can be moved to different rooms as needed, working wherever humidity could damage objects or electronic systems.

This compact dehumidifier is equipped with a washable and replaceable polyurethane filter , rubber feet and a mechanical dehumidifier pre-installed on the machine.

How a dehumidifier works

A dehumidifier is a machine that draws in air and filters it. The air passes through a radiator filled with refrigerant gas . The low temperature condenses the humidity , collecting the waste liquid in a tank. The dehumidifiers in the FDK Fral line are equipped with a hot gas defrosting system with electronic and thermostatic control, allowing them to operate at temperatures as low as 0°C.

Functional specifications

Robust structure in galvanized sheet metal

Fral FDK100 is made of hot-dip galvanized sheets which are subsequently painted using epoxy powders, thus ensuring high resistance to atmospheric agents and aggressive environments.

Rotary compressor

The compressor mounted on the Fral FDK100 dehumidifier is of the rotary type mounted on anti-vibration mounts.

Refrigerant circuit

The evaporator and condenser coils are made of copper tubes and aluminum fins .

Fixed exhaust

The Fral FDK100 dehumidifier does not have a condensation collection container and therefore needs to be connected to a fixed drain .

Condensate lifting pump

To avoid the need for a fixed drain, you can separately equip your Fral FDK100 dehumidifier with a condensate lifting pump kit. Connected externally to the machine, this kit allows condensed water to be expelled up to a height of 3.5 m above the dehumidifier. This kit is pre-installed with malfunction alarms to prevent unwanted effects such as blockages or water leaks.

Axial fan

The fan mounted on the FDK line is of the statically and dynamically balanced axial type.

Hot gas defrosting

It allows the dehumidifier to be used in environments with temperatures down to 0.5°C , it is a special hot gas injection system to speed up the defrosting of ice formed in the evaporator.

Air Filter

The air filter with which the Fral FDK100 is equipped is made of polyurethane and is entirely washable and easily replaceable for better maintenance. High efficiency filter .

Microprocessor

The Fral FDK100 microprocessor controls the defrost cycles , the compressor timer and the alarm board.

Pre-installed dehumidifier

The dehumidifier is mechanical and located on the side of the machine. It complies with European regulations.

Technical specifications

This dehumidifier for industrial spaces is the ideal machine for removing and/or controlling humidity in rooms . Its air flow rate is 1100 m³/h with an average nominal power consumption of 1000 W. Fral FDW44 uses R1234yf gas for both operation and the defrosting system.

The industrial dehumidifier in question has 4 rubber feet and two sturdy handles for easy transport and a durable powder-coated structure to withstand atmospheric and aggressive agents. The noise level of this machine is 56 dB(A) and it is designed for use with a fixed drain or with the optional kit with a condensate lifting pump with a 3/4" connection .

Fields of operation:

T < 30°C = relative humidity between 35% and 98%
T 30 - 32°C = relative humidity between 35% and 90%
T 32 - 35°C = relative humidity between 35% and 70%
