40kW heat exchanger is designed to provide efficient and reliable thermal transfer from an external heat source (e.g., boiler, solar system, or heat pump) to your swimming pool or spa. Available in titanium (for saltwater/chlorinated water) and 316L stainless steel (for freshwater), it is a durable and compact solution for heating residential and small commercial aquatic systems.
