Dehumidifier for floor cooling system DUMY FLOOR EMMETI 2018

The Dumy Floor dehumidifiers reduce humidity in the environment.


A complete range of encased or built-in, wall or ceiling-mounted dehumidifiers, allows humidity control and blends in perfectly with all types of room. Use of the double water coil refrigerant cycle allows the Dumy Floor dehumidifiers to reduce humidity in the environment, in a way that the inlet and outlet air have the same temperature.
Given that water particles do not require air movement in order to diffuse, this means that draught is minimal and localised.
The availability of cooled water (15-20°C) used in the underfloor system suggested the introduction of additional heat exchangers in the EMMETI dehumidifiers, which greatly improve performance of the same with respect to traditional dehumidifiers.

The inlet air first passes through a dust filter _ and then passes to a first stage characterised by a high efficiency finned coil, where the heat is lowered greatly by making use of the delivery water in the radiant system. Successively, the saturated air gives up some of its latent heat on passing through the evaporator of the cooling circuit _.

The cooled and dehumidified air is then heated by the condenser _ and taken to room temperature by the last coil _ which, still using the cooled water, makes the final temperature of the treated air neutral.
Main components description
The machine is made entirely in galvanised sheet. All of the heat exchangers are made in copper-aluminium with additional hydrophilic treatment on the first two coils; this prevents the formation of drops of water on the same.
By making the condensate run into the tray, which has a steep slope and is made in plastic, in turn it expels all of the water, thus preventing stagnations that can lead to the formation of bacteria and mucilage.
The circulation of air is forced by a silent centrifugal fan. Particular attention has been paid to the cooling circuit, characterised by a high efficiency hermetic reciprocating compressor.

A capillary expansion device joined to a series of set-ups aim at reducing noise problems linked to the circulation of the freon and, even if small, vibrations of the compressor. The machine is managed by a dedicated circuit board fitted with a latest generation microprocessor and able to optimize dehumidifier operation.
