Desiccant Dehumidifier or Compressor Dehumidifier?
Posted on September 12 2019
There are two main types of dehumidifier – Compressor and Desiccant Dehumidifiers. Each of these two types of dehumidifiers have unique attributes that make them suitable for different applications depending on the prevailing conditions. Ebac manufacture both types of dehumidifiers and are best placed to give completely impartial advice.
Ebac’s compressor dehumidifiers with Smart Control are between £50 to £150 cheaper to run per year than a desiccant dehumidifier.
- Desiccant dehumidifiers remove water by natural absorption.
- They use an electrical heater to continuously regenerate the adsorbent material – ie they dry the absorbent material out so it can collect moisture again.
- They have high extraction capacities at typical UK winter conditions
- However, this high extracting capacity is often misused.
- A domestic desiccant dehumidifier removes around 3 times more moisture than is required for an average British home with 4 occupants.
- A typical desiccant removes up to 8 litres of water per day, however, the average UK home only requires around 1 to 2 litres of water extraction per day.
- This additional water extraction is 100% wasted as the moisture is simply pulled in from outdoors
- Desiccant dehumidifiers consume substantially more amount of energy to run than compressor dehumidifiers with no additional benefit.
- Desiccant dehumidifiers are perfect for locations where temperatures may drop below 3°C, such as garages, unoccupied properties, caravans etc.
- Ebac manufacture desiccant dehumidifiers for industrial clients who have large amounts of moisture to remove from swimming pools, construction or building projects where running costs are not important.
- Compressor Dehumidifiers remove water by producing a cold surface that the moisture condenses on.
- They use refrigeration technology to make a cold surface.
- Refrigeration is more energy-efficient than drying an absorbent material by heating.
- A fan sucks in the air, the air releases its moisture on the cold surface and dry, warm air is then pushed back out into the room.
- A typical compressor dehumidifier removes up to 3 litres of water per day, however, the average UK home only requires around 1 to 2 litres of water extraction per day.
- A compressor dehumidifier, therefore, provides the optimum level of water extraction at the lowest cost.
- Compressor dehumidifiers use less energy to run than desiccant dehumidifiers.
- If you use Ebac’s patented Smart Control that energy-saving increases to 35% over dehumidifiers with a manual humidistat.
- The performance of the dehumidifier is determined by the design and setup.
- It’s essential to purchase a dehumidifier that is designed for UK temperatures and climate.
- Compressor dehumidifiers are perfect for use in the home – where temperatures rarely drop below 10°C.
- Ebac manufacture compressor dehumidifiers for domestic use – as they are the perfect fit for the requirements of a house.
