User Manual
HRQ-HUM-HomEvap-200
The humidifier can be used on any HRV type where moisture is not exchanged between supply and return air.
5.1 Description of the components
The main components of the humidifier are:
The housing
The housing of the humidifier 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 Mounting rings. At the bottom is the compartment there is
a water valve, controller board and transformer located. These are protected by an EPP cover bearing safety
symbols. On left and right side the duct connection is located, diameter R200mm internal and 250mm outside
Internal construction
The internal construction has been developed to provide an optimum air flow that is safely humidified. It
consists of a cassette in which the patented legionella-safe filter, LegioSafe and the matrix are fixed. The supply
water passes through the filter after which the filtered water humidifies the matrix. The air supplied passes
through the matrix and is humidified by contact with the wet surface. Surplus water is drained. The PTC air
heater heats the air supplied if this falls below the setpoint.
Humidity and temperature sensor (SHC80)
The SHC80 duct sensor also supplied measures the relative humidity and temperature in the duct after the
humidifier. This position guarantees the maximum operation and condensate-free ducts under the normal
conditions of use of our design.
The control
The humidifier is controlled by a (wireless) control panel. This control panel fitted with batteries (4xAAA) is
linked uniquely to the humidifier. See separate Controller manual..
5. How to use
4.2 Safety
The water is legionella-safe because of the built-in, patented, legionella-free LegioSafe water filter and
distributor. The supply water first passes through the LegioSafe before it moistens the matrix. As a result there
is no risk for the inhabitants of houses or building. Only fresh water is used. There is no recycling of water.
The matrix is completely dry if there is no demand for cooling/humidification.
The SHC80 duct sensor supplied also measures the relative humidity and temperature in the duct after the
humidifier. This position guarantees the best efficiency and safe operation, no condensate in ducts under the
normal conditions of use of our design.
The built-in PTC air heater has several safety devices:
1. A mechanical safety device that ensures that the air heater demands no more power after exceeding
a maximum temperature of 85°C.
2. An extra temperature sensor in the humidifier that switches the air heater off at too high a temperature.
