This calculator calculates the required chlorine generation capacity based on a private use case. For public facilities, we recommend individual consultation, and we are happy to advise you via email, telephone, or in person. We look forward to hearing from you.

Choose your pool type

Which pool variant is the best?

Here are some considerations that can help you determine the right pool size for your needs:

The obvious first: larger pools are generally more expensive to purchase, operate and maintain. If you only want to use your new pool for cooling off and occasional leisure use, a smaller pool may be sufficient. If, on the other hand, you swim for sport or regularly organise social events with lots of guests, you may need a larger pool. A professional can help you and make sure you get a pool that meets your needs.

Membrane electrolysis

Thanks to the continuous dosing of highly effective chlorine in the form of hypochlorous acid, the right amount of active chlorine is in the water at all times. This means that even people with sensitive skin can bathe in the water. Eye and skin irritation as well as unpleasant swimming pool odours are avoided.

The cost of producing active chlorine with an electrolysis system is significantly lower than the price of purchasing commercially available chlorine bleach. The need for pH-regulating care products is drastically reduced. This reduces the risk of accidents. Thanks to the modern membrane cell technology, the bathing water does not become oversalted.

The ECO-a system

Our new ECO-a series offers many advantages of our previous systems paired with new developments and improvements for use in swimming pools. In particular, the advantage of being able to position the salt and product tank independently of the system enables maximum user-friendliness in the planning and operation of your swimming pool.

The integrated control system regulates the output and monitors all operating parameters. The hydrogen produced during the process is separated by a degassing tank and must be discharged to the outside. The fresh sodium hypochlorite is fed into the product tank without an additional pump and can be dosed from there as required.
