Vacker supplies swimming pool dehumidifiers and Spa dehumidifiers for hotels, homes, villas, commercial buildings, Olympic pools etc. Swimming pools and Spas generate a lot of humidity because the water from the pool is heated. Swimming pool dehumidifiers are used for such purposes. There is a difference in temperature between the water and air. This also causes higher humidity in the area. The heated air generates moisture and is released into the air. Indoor swimming pools and basement dehumidifiers especially are a big menace.
This causes huge humidity in the area which is very harmful. Hence, the surrounding air must be dehumidified properly. Properly selected swimming pool dehumidifier can reduce the humidity to normal levels.
How to reduce the humidity caused by indoor swimming pools and Spas?
Outdoor and indoor swimming pools generate excessive humidity. However, the problems are severe in indoor swimming pools. moisture is unable to find a way out and gets deposited everywhere including inaccessible areas. You can see moisture condensation on walls adjacent to the pool. This causes damage to paint, wooden doors & windows, metal doors & windows etc. Also, clothes, curtains, paintings etc. in the surrounding rooms will be affected. Mould formation happens on the walls and the upper layer of painting and cementing peels off.
In order to reduce the moisture from the air, you have to use a dehumidifier specifically designed for this purpose. Normal dehumidifiers are not suitable for this environment with high chlorine content. A swimming pool dehumidifier extracts moisture from the air and removes out of the pool area completely.
In addition to this, the swimming pools are treated with chlorine. Hence, the moisture in the water vapour is filled with chlorine particles. This adds to the woes of high humidity. This is detrimental to all articles around the pool.
Dehumidifiers for swimming pools and Spas
Swimming pool dehumidifiers are designed to solve the challenges of high humidity. They are multifunctional units which also provides heating of the air if required. This is the main difference of indoor pool dehumidifiers from normal industrial models. These dehumidifiers are entirely automatic and the humidity levels are controlled by a humidistat or hygrostat.
These automatic controls ensure that the swimming pool is in a wellcontrolled environment. The humidity and air temperature control results in a stabilized environment.
Our swimming pool dehumidifiers are designed in such a way that it uses very little energy for dehumidification and heating of the air. They recover the energy from the dehumidification process and are recycled to heat the air if required. These dehumidifiers are usually closedloop system with simple maintenance.

Indoor swimming pool dehumidifiers
All of our indoor pool dehumidifiers can also be used for external pools. However, the calculation for indoor pool dehumidifiers will be entirely different. For indoor pools, the area is enclosed. Hence, the air volume is considered for the enclosed area.
Outdoor swimming pool dehumidifier
For outdoor pools, the unit will be working in continuous mode since the air will be continuously exchanged. In both cases, the dehumidifier is installed on the wall and water is drained out. The effectiveness of a dehumidifier for an outdoor pool is limited. The reason is that for an outdoor pool is open to the outdoor air and hence no control of the air intake. However, if you have any particular items or area to protect from high humidity, you may place a dehumidifier near to this area.
The principle of pool dehumidifier
These are condensation type dehumidifiers, which convert moisture into the water. There are condensation coils which cool down the air and absorbs the moisture content. This moisture is converted into water. A drain pipe has to be connected to drain out the water.
