Dehumidifier Unibond Aero 360 Pure Moisture Absorber System Chemical (1 x Pure Tablets Pack 2's)

Product Information

The Passyfier Core 100 Vent is a through-the-wall Core Dehumidifier Vent capable of transmitting up to 1 Litre of water vapour per 24 hours. This process works most effectively at higher ambient temperatures with a high dew point temperature. Perhaps the first materials for such electrolysis-based dehumidification were solid polymer electrolyte (SPE) membranes. Following on from this, with fewer moving parts, they also tend to require less maintenance – there is much less that can go wrong with these machines so you are much less likely to need to get them repaired.

While you may be able to clear it yourself, it is usually an indication of a larger problem that will need to be addressed otherwise the problem will recur. Since the saturation vapor pressure of water decreases with decreasing temperature, the water in the air condenses on the surface, separating the water from the air.They’re not as expensive as desiccant units but much more effective than peltier driers so are particularly well suited to these kind of applications. This happens continuously until the desired RH level (if you’re using a humidistat) has been reached.

If you are looking for a dehumidifier then you’d be better off making your decision based on the airflow rate, power consumption and extraction rates to identify the most suitable unit.

Desiccant dehumidifiers don’t have this issue, and work equally well no matter what the temperature. As we’ve covered elsewhere on the site, a refrigeration system works by pumping a substance with a very low boiling point around a sealed circuit containing components that increase and decrease the pressure. As the air passes through the coils, the water condenses and then drips down into a separate section of the unit.

But no, it’s not right because we haven’t taken into account the moisture in the external air that will seep into the room. The moisture vapour pressure within a dwelling is always higher than the outside pressure therefore there will always be an escape of moisture vapour by the diffusion process through the Passyfier Vent.

If however the application you’re looking at stays between 15-35°C then an air defrost system might be a viable alternative. The vast majority or portable dehumidifiers utilize the hot gas defrost method of ice removal, not only is a more effective system it can be used at lower temperatures and can therefore be left unattended, which might come in useful if you have anu application that needs the unit to be left running overnight or in winter.

The constant arrival of this is new air from the loft forces the old, stale, damp air out through your homes natural leakage points leaving the house fresher, dryer and condensation free. Next-generation HVAC: Prospects for and limitations of desiccant and membrane-based dehumidification and cooling". Now, while there is some logic in thinking the higher the extraction rate is the better it will be for my large room, please bear in mind that you’ll also need a greater airflow rate. This diagram shows the schematic layout of a typical dehumidifier featuring a hot gas bypass circuit and names the major components.

They’re single use and require regularly replacing, uneconomical and have no way of circulation the air so cannot really effect the overall RH level of an entire room. As the wheel rotates the hygroscopic media passes through a separate isolated chamber where air is heated so the moisture passes back from the wheel to the air and is exhausted away.
