PRD-HX-STDמחליף חום נירוסטה (רדיאטור)
Stainless steel water-to-water heat exchanger for mikveh heating systems and hot water applications. Transfers heat from a boiler or solar system to the pool without mixing circuits. 25–30 year service life. Sized to your mikveh volume and heating load.
Details & OrderHow It Works
Water at a Consistent Temperature All Day
The heat exchanger transfers heat from the boiler to the mikvah water — without mixing the two circuits. The mikvah reaches the correct temperature (34–37°C) and holds it throughout the day.
PDS sizes the unit to your specific pool volume and heating source — you don't need to know the engineering.
