3 General characteristics of the humidifier
The humidifier REH is a range of humidifiers based on electric immersion heaters specifically designed for
installation inside air handling units.
Normally in these applications, the humidifier is installed externally to the air handling unit and the steam is
conveyed through pipes inside the units and distributed through stainless ramps that allow the steam mixing
with air.
This solution has numerous drawbacks and additional costs:
-
The construction of a technical compartment exterior to protect the humidifier
-
An antifreeze device which ensures that the water in the humidifier does not freeze in the absence of
a request for production
-
The use of expensive and bulky rubber tubes for the conveyance of steam-
-
The use of steel distributors within the UTA
-
The formation of condensation inside the tubes and distributors with decreased performance
-
The need to install the pipes avoiding traps and depressions that would prevent the steam to flow
properly
-
The loss of heat to the outside through both tubes, but especially in the humidifier itself exposed to
low temperatures.
The family of REH humidifiers, as well as the VEH (electrodes) and SSH (steam heat exchanger) families, is able
to overcome all these problems, greatly simplifying the installation costs and increasing the performance of
the product compared to the corresponding humidifiers usually on the market.
4 Structure of REH humidifier
The humidifier REH consists of two units electrically connected to each other: the hydraulic unit and the mi-
croprocessor-based control unit. The hydraulic unit is installed inside the AHU, lying on the condensate drain
pan immediately downstream of the cooling coil. The control unit can be positioned into the AHU electric panel
or on the AHU panels.
The hydraulic unit is constituted by a kettle of stainless steel with dimensions 52 cm x 80 cm x 15 cm in height.
