Hot spring water compatible type

These optimal-temperature bath water replenishment units can handle hot spring water and seawater. The bypass function allows manual temperature control during maintenance or parts replacement work.

*Precautions:

The optimal-temperature bath water replenishment units for hot spring water cannot necessarily be used with every type of hot spring water that is available in different regions of Japan.
Although the major components of the units are made of stainless steel, they should not be used with highly acidic seawater or hot spring water due to the corrosive effect.
Internal parts need to be cleaned and also replaced regularly. The frequency of cleaning and replacement varies depending on the quality of the hot spring water being used.
