Now, if you’re looking to extract moisture form the air within an environment with a less stable ambient, where the temperature has big swings and can fluctuate between, say, 5°C-35°C then it might be wise to opt for a refrigerated unit. When calculating which dehumidifier is best for your application just must remember to take into account the airflow rates of units rather than just extraction rates. It’s all fine and well having the most powerful unit on the market but if it’s only got a tiny airflow it will only really be processing the same bit of air over and over, and have negligible effect at the other end of the room, so please remember the more powerful the unit the greater the airflow should be. If however the application you’re looking at stays between 15-35°C then an air defrost system might be a viable alternative.

As with the commercial units, moist air from the room is drawn into the unit by a fan and blown across a rotating wheel. When compared to their refrigerated cousins semiconductor driers offer a poultry 25% efficiency, so they really aren’t a viable alternative for anything other than very small applications. You see, desiccant dehumidifiers contain certain substances (a desiccant), usually Zeolite, which are particularly good at absorbing water from the air. Klarstein offers a wide selection of high-quality dehumidifiers, because we like to leave tropical climates just for holidays. This buildup prevents the dehumidifier from operating effectively, and can cause water damage if condensed water drips off the accumulated ice and not into the collection tray.

The ideal room environment is not only good for comfort it is essential to guard against damage to expensive furniture, documents or sensitive equipment. Our tip for an average-sized room: DryFy Pro Connect - the smart app control in conjunction with the integrated UV air sterilisation effectively ensure a healthy and space-saving climate. Although this system can work well in warm climates when the environmental temperature drops below about 15°C the surface temperature of the evaporator coils falls below 0°C and the ice formation becomes quicker and more aggressive, meaning the sensor has the unit in defrost almost permanently.

The reason for the limited acceptance of desiccant dehumidification can be attributed to initial installation costs, the fact that operational benefits are not fully understood, lack of technology awareness, and company priorities, which are not focused on benefits of new technology. In addition to the health-promoting arguments and the increased well-being by fresh air, electrical dehumidifiers can be used in a versatile way and can be adjusted as needed. The remaining, now moisture-free, air is then warmed back up to room temperature before being blown back into the room. Whilst both fulfill the same purpose by extracting moisture from the air, they achieve this via different methods.

We'll introduce you to the different types, explain their respective properties and clarify again why we have a clear favourite. As we can see, if your looking to control condensation or then it’s the relative humidity level that needs to be dealt with. 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. As shown in the saturation curve at the start of this, the capacity of air to absorb moisture is entirely dictated by the temperature; the lower the temperature the less it can hold, the higher it is the more it can.

The most common applications though are probably building sites where you’ll find mid range industrial dehumidifiers helping to dry out plaster etc.Well that’s because they come in the biggest range of sizes, extraction capacities, airflow rates and are arguably the most versatile. Our smaller desiccant models have a power consumption of approximately 250-550W compared to 210W from our similarly sized compressor models. In day to day life it’s the RH level that causes most issues and often the first we know about it is the signature musty smell, a damp patch or speckled mould on a wall.

Desiccant dehumidifiers are always best for use in spaces where the temperature is likely to drop below 10°C for any extended period of time. From morning dew to steamy car windows whenever damp air comes into contact with a cooler environment or surface the moisture within it will condense, and this is the principle on which refrigerant dehumidifiers work. Selective membranes can be made by immobilizing a liquid that can absorb water (or another solute) within a membranes, dubbed "supported liquid membranes".One of the most popular uses for industrial dehumidifiers is on building site where it can get pretty cold during the winter months even with doors and windows in but without the heating yet plumbed in, with this in mind most portable dehumidifier manufacturers will have a hot gas defrost in their systems. The resulting condensate does not end up in a container, but goes outside via a hose and an opening in the building. Today, warm condensation technology, based on the concept of over-saturated steam inside a closed environment, [ clarification needed] makes it possible to dehumidify air at sub-zero temperatures.
