Evap accessories

Operation

The purpose of the Evap is to humidify air passing through wetted media in an energy-efficient, silent and safe way. The adiabatic humidification process is carried out in the humidifier unit and increases the humidity in the air supply to the room.
The Evap humidifier must be installed in the air duct to the building.

Principle of operation

The Evap is installed in the air duct to the building. The humidifier operates completely independently and switches on when the (absolute) outside air humidity becomes too low.
The switching is linked to the prevailing outside temperature, using an average meteorological year as the reference year. This value is controlled by the T3 temperature sensor, which must be installed in the outdoor air duct. The default temperature setting for triggering the Evap humidification unit is 12°C.
The Evap then humidifies the supplied air until that air reaches a maximum relative humidity of 78%.
The integrated PTC preheater is only operational when the air temperature is lower than 17°C after humidification. This limits the energy usage of the PTC preheater.
The maximum moisture supply capacity is 4 kg/h (approx. 4 liters per hour) and is highly dependent on the air temperature and air flow across the Evap humidifier. The maximum air flow capacity of the Evap is 600 m3/h

Safety

The water is legionella-safe because of the built-in, patented, legionella- free LegioSafe water 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 buildings. Only fresh water is used. There is no recycling of water. The matrix is completely dry if there is no demand for humidification.
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.
The Evap air humidifier has several safety features:

1. A mechanical Klixon temperature switch that switches off the PTC preheater if the set temperature is exceeded.
2.  An additional temperature sensor in the humidifier unit that also switches off the PTC preheater if the set temperature is exceeded.
3. Legionella shutdown protection. If the air humidifier unit is switched off for 72 hours, the water valve will automatically open and flush the pipes and the Evap cassette for 30 seconds to prevent legionella from forming.
4. Water valve security. The filter in the water supply coupling ensures that dirt can not damage the water valve.

Use

The Evap can be used on any central balanced ventilation system.

Description of the components

The main components of the Evap are:

The inner part
The inner part 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.

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.

Maintenance

The Evap humidifier is equipped with a removable EVAP cassette
(article code 351025) in which an EVAP matrix and LegioSafe filter are mounted. The matrix cannot be cleaned. The EVAP cassette must be replaced if the RV% measured by the duct sensor (SHC80) is no longer above 50%.
If this happens, an alarm is generated. See chapter 6. The service life depends on the number of dissolved minerals in the water. The water hardness is an indication of this. With a water hardness of> 9dgH, the service life is probably shorter than the service indication.

The LegioSafe filter is in the EVAP cassette. The lifespan of this is determined by the number of sediments in the water. The service indication is valid for water that has a TDS value of less than 350ppm. (TDS Total Disolved Solids)

If you want to know what the water quality is in your area, you can request this from your water company. If these values are higher in the water, we advise you to take appropriate measures. For example, consider a sediment filter or a reverse osmosis water filter.

If the values are higher than stated in table 4.1, the service life of the cassette is shorter.
The Evap cassette must be replaced at least every 2 years or if the service indicator light for filter replacement comes on. The visible service message is an LED light (next to the key symbol) on the bottom of the humidifier.

ATTENTION: the operations for replacing the cassette must be carried out by an authorized person.

Procedure for replacing cassette

1. Remove the plug from the socket.

2. Disconnect the water supply.

3. Make sure that the drain hose is free and can move with the movement that is necessary to gain access to the top.

4.  Make sure that the water supply hose has sufficient room to move with it, or disconnect from the tap.

5. Undo the screws on the side of the brackets so that the Evap humidifier can be turned in the bracket. Use a crosshead 2 or 3 screwdriver.

6. Turn the Evap humidifier 90° so that the cassette is accessible. Take into account any leakage water from the side of the unit!

7. Disconnect the Evap cassette from the water supply by pushing in the ring of the knee joint (on side of the housing) and sliding the whole knee off of the black hose. In this way the cassette is disconnected and can be removed.
   

8. Pull/slide the cassette from the Evap humidifier, using the supplied tool (large plug).

9. Clean the inside of Evap with a soft cloth if necessary.
   Do NOT use a cleaning product!
