DRY dehumidifiers are leading Microwell swimming pool dehumidifiers used in 30+ countries to mainly control the humidity in pool and spa areas. DRY dehumidifiers are also vastly used for areas that require effective humidity control with a machine which is as quiet and as less disturbing as possible.

DRY800 range is suitable for pools and water areas with water surface up to 90m2.

DRY800 range is designed for high moisture extraction, low energy consumption and low noise.

DRY800 unit extracts 90 liters of vapor from air per day at typical pool conditions of 30°C air temperature and 60% relative humidity. DRY dehumidifier series is designed to do the job in other possible environments. It provides with a significant extraction of almost 70 liters per day at 5°C air temperature and 80% relative humidity and excellent almost 160 liters at 35°C air temperature and 80% relative humidity.

Thanks to outstanding design, leading technology and up-to-date concepts, Microwell products achieve up to 36% lower energy consumption than the others. Our product saves you money every day and helps to keep your bill under control.

DRY dehumidifiers are low energy dehumidifiers designed to save energy costs every hour they run. DRY800 model uses on average only 1600W of energy. In return the unit provides with an effective humidity control through massive extraction and high heat recovery up to 5100W.

Dehumidify and heat by one device. DRY800 provides with heat recovery of 5100W while consuming only 1600W. The unit, while dehumidifies, provides with a free heating which can be subtracted from your current heating system. You thus will save twice while running this machine. Should more heating be required, the unit can be equipped with either LPHW (Low Pressure Hot Water coil) or electrical heater with a combined maximum heating ability of an amazing 12.1kW!

DRY dehumidifiers are installed in:

  • Swimming Pools
  • Spas
  • Hotels and Wellnesses
  • Hot tubs and Jacuzzis
  • Fitness clubs
  • Gyms
  • Museums and archives
  • Warehouses
  • Drying rooms for laundry, breweries
  • Military storages
  • Bakeries
  • Wine cellars

DRY800 range can be mounted on a wall to be out of the way and yet be in position to be in control of humidity. Should the unit be completely hidden or due to electrical safety it cannot be installed directly inside pool or hot tub area, the dehumidifier can be installed out of pool hall. DRY dehumidifiers can be mounted in a technical room providing humidity control through through-the-wall ducts with 2 elegant grills visible from pool hall or as a duct model installed in technical room with air ducting installed for air circulation in pool hall.

DRY800 THROUGH THE WALL comes in a cover made from galvanized steel finished with powder coated enamel protected with anti-corrosive plastic layer. The cover can be painted in any color according to customer’s wishes. Metal provides elegance and just-right-fit in a pool. Material is 100% resistant against typical aggressive substances in pool such as chlorine or salt. Cover is well grounded with all other metal parts of the unit providing full safety. All connections and hanging of the unit are located on its back side, so no cables or hoses stick out of the unit. The unit is one compact piece only 300mm thick so it essentially blends into your pool and saves space.

The set includes wall ducts which allow the unit can be mounted behind up to a 400mm thick wall. The ducting is made from galvanized steel. The cover has several separate compartments from the front which easies the access to machine’s parts.

Control or regulation of the unit is very important for a customer. DRY800 model provides with all possible options you may require. You may go for a classic old school built-in rotary humidistat; you can upgrade to a remote wired humidistat to place it on a wall; you can regulate the unit using remote wireless digital control or simply use built-in digital control. All controls are designed for accuracy and customer comfort.

Noise level is a frequently asked question. DRY dehumidifiers are probably the quietest on the market with only 46dB(A) applying Microwell unique technology ultraQUIET+ eliminating any excessive noises or vibrations. Typical noise level of a quiet room is 30dB(A), typical conversation between 2 people can rise up to 60dB(A). Unit’s 46dB(A) at air flow of 1100m3/h, extraction rate of 160 liters and extra heating of 12.1W just confirms how unique Microwell machines are.

DRY800 model uses 5 speed AC fan simulating DC energy saving operations.

DRY800 model is gentle to environment and eco-friendly as it uses the most advanced R410A refrigerant.

The unit can supply fresh air in excess of 30% of its nominal air flow, i.e. about 330m3/h. The air is effectively preheated by hot condenser prior it enters pool hall.

Air aggressiveness is very important to a dehumidifier as it typically operates in a chlorine or salty environment. Microwell ensures probably the highest protection of the whole machine and its components. The coils are from anodized aluminum fins coated with GoldFin epoxy finish. Copper pipes are finished with zinc coating for a maximum protection against aggressive substances present in typical pool’s air. All metal parts are galvanized and powder coated, where needed stainless steel or titanium of highest pureness is used.

The units are manufactured in European Union complying with very strict engineering standards. To ensure absolute quality, each unit is individually tested for full operations before it is packed and loaded on truck or container. The factory is certified according to ISO9001, ISO14001 and ISO18001. Each unit is certified against EU standards holding CE certificates and full Conformity. Other compliant standards are RoHS and IP44.

DRY dehumidifier series have widest range of makes and accessories options on the market. The unit can be adjusted and tailored is such a way that seemingly there is no pool or spa or hotel this dehumidifier could not serve. Please see below section of Standard equipment and Accessories for more information.

Typically, the unit is in stock near you. Due to many different ways the unit can be tailored on demand, it may take up to 10 days to deliver the unit to you.

DRY dehumidifiers are amazing due to their micro+ features providing they have by standard. More info micro+.

Humidity is not an enemy when controlled but can cause serious troubles otherwise. Ideal humidity for pool or spa users is when they feel comfortable. This feeling is achieved by an ideal relative humidity from 55% to 65%. Humidity above 70% is detected by condensation on windows and walls and the humidity continuously deteriorates the pool or spa environment. It is also a perfect environment for mould and bacteria to grow. Humidity lower than 45% actually causes a reversed problem to bathers in the form of dry feeling and possible harm to mucous tissue. The innovative series of Microwell dehumidifiers keep the humidity at ideal 55%-65%.
