The Fral industrial dehumidifiers of the series FD are suitable for humidity control in commercial and industrial spaces. Particularly sturdy and durable, they can be easily installed and are easy to maintain. They can also be placed in environments for the preservation of food products or in industrial processes where humidity control is necessary. They feature a washable air filter and must be connected to a fixed drain. They are equipped with an onboard mechanical dehumidostat. Is it possible to connect a remote digital dehumidostat. The Fral fixed dehumidifiers of the series FD can be equipped with an optional HOT GAS defrosting system, with electronic and thermostatic control, and can work with temperatures close to 0 °C.


FRAME MODELS FD160 – FD240 Structure with panels made of sturdy galvanized steel, painted with epoxy powder ensuring high resistance to atmospheric agents and aggressive environments. The panels are removable to allow a quick inspection and maintenance of the internal parts

COMPRESSOR Rotative compressor (FD160) or scroll (FD240 – FD360 – FD520 – FD750 – FD980), mounted on vibration dampers. Provided with resistance on the housing and thermal safety.

REFRIGERANT CIRCUIT : Evaporator and condenser: the coil is made of copper pipes and aluminium fins. Drying filter, Shrader valves, minimum and maximum pressure switch. Defrosting thermostat and solenoid valve in version S.

CONDENSATE COLLECTION TANK : MODELS FD160 – FD240 The tank is in plastic non-corrosive, the dehumidifier should be connected to a fixed drain, preventing the formation of double siphons. Attach a tube with 3⁄4″ F coupling to the welded fitting of the tank.


FAN Centrifugal double suction fan, built with sturdy blades in galvanized sheet, statically and dynamically balanced. Protection degree: Three-speed fan.

HOT GAS DEFROST Enables to use the dehumidifier in environments with temperature up to 3 °C. It is a special hot gas injection system to accelerate the defrosting of the ice formed in the evaporator.

AIR SUPPLY The air supply is supplied as standard on the side opposite to the air inlet, but you may require the dehumidifier in TOP version (with delivery on the top side of the machine).

AIR FILTER The air filter, supplied as standard with the unit, is washable and easily replaceable. It is in Polyurethane and High-efficiency filter.

MICROPROCESSORControls the defrosting cycles, the compressor timer and the alarm card. The dehumidifier is equipped with step sequence control.

CONTROL PANEL AND ELECTRICAL CONTROL PANEL Located in the side area of the machine. IP protection degree. Made in compliance with the European standards 73/23 and 89/336.

TESTING Tests are performed to check the tightness of the refrigeration circuit. Electrical discharge tests and functional tests are performed as well.

TECHNICAL STANDARDS This dehumidifier meets the essential requirements included in the Directives of the European Community 2006/95/EC of 12 December 2006 on the safety of electrical products for use in Low Voltage; 2004/108/EC of 15 December 2004 in the field of electromagnetic compatibility; 2006/42/EC of 17 May 2006 in the fields of machinery safety.

The conformity is declared with reference to the following harmonized technical standards: CEI-EN 60335-2-40, CEI-EN 55014-1, CEI-EN 55014-2. We also declare that the product is manufactured in compliance with the RoHS Directive in force, that is 2002/95/EC, transposed with the Legislative Decree of 25 July 2005 no. 151 (article 5).
