Evap 3
Section 3 – Use
The Evap can be used on any central balanced ventilation system.
3.1 Description of the components
The main components of the Evap are:
The housing
The housing of the Evap is made of EPP (expanded polypropylene). The advantages of this material are its low
weight, good water tightness, good air tightness and recyclability. The housing consists of an upper and a lower
part that are fixed to one another by two fixing rings. At the bottom is the compartment with the water valve, the
controller board and the transformer, sealed by an EPP cover bearing safety symbols. On both sides there is a
round duct connection of d=200 mm internal and d=250 mm external dimensions.
Internal construction
The internal construction has been developed to provide an optimum air flow that is safely humidified. A
cassette is fitted in the Evap humidifier, in which the patented legionella-safe filter, LegioSafe and the matrix
are installed. The supply water passes through the filter, after which the filtered water humidifies the matrix.
The supplied air is passed through the matrix; humidifying occurs through contact between the air and the wet
matrix surface. Surplus water is drained. The PTC preheater is only operational when the air infeed
temperature falls below the set minimum temperature.
Humidity and temperature sensor (SHC80)
The SHC80 duct sensor also supplied measures the relative humidity and temperature in the duct after the
Evap. This position guarantees the maximum operation and condensate-free ducts under the normal conditions
of use of our design.
Temperature sensor (T3)
The temperature sensor T3 is a temperature probe that must be fitted in the outside air intake duct of the HRV
unit. The T3 determines automatically when the Evap humidifier is switched on or off.
3.2 Description of accessories
Controller (optional)
The Evap humidifier can be operated, read and set using a (wireless) separate controller.
The control panel is fitted with 4xAAA batteries and is linked solely to the Evap humidifier. The relevant
instructions are in the Evap controller manual.
Operation
As soon as the relative humidity sensor in the controller measures a lower humidity than the set value, the Evap
humidifier is activated. The software has been designed to achieve an optimum output with minimum water
consumption and at lower energy costs.
Safety
In addition the control has a number of other built-in safety devices and indication functions.
The signalling lights of the control PCB are at the bottom of the humidifier.
The necessary reports are also transferred to the display.
