Bowman EC100-5113-2S Marine Heat Exchanger
Bowman's EC100-5113-2S is a marine-grade stainless steel shell-and-tube unit prized in hydrotherapy for its pressure tolerance and compact footprint, making it ideal for clinic and mobile spa installations. It holds its position by combining rugged British engineering with lower upfront cost than titanium alternatives and better long-term corrosion resistance than many consumer pool units, while delivering higher pressure ratings than typical Jandy or Waterco models. For facilities that prioritize durability and tight installation spaces, it offers a cost-effective balance of performance and lifecycle value compared with the higher-capex Pahlen titanium and the more consumer-oriented AquaCal and Jandy options.

AquaCal STK055 Stainless Steel Heat Exchanger
The AquaCal STK055 is a stainless steel shell-and-tube exchanger tailored for spas and hydrotherapy systems, known for straightforward compatibility with North American heaters and economical upfront pricing. It stands out for easy parts availability and lower installation complexity than some marine or industrial units, making it financially attractive for small clinics replacing aging equipment. Compared with more heavy-duty Bowman or premium Pahlen titanium units, the STK055 trades off extreme durability for lower capital cost and simpler maintenance in typical chlorinated hydrotherapy environments.

Pahlen Hi-Flow HF210 Titanium Heat Exchanger
The Pahlen Hi-Flow HF210 uses titanium tubes and a robust shell to deliver unmatched corrosion resistance and flow capacity, making it the market leader where saline or high-chlorine hydrotherapy is used. Although it carries a higher upfront price than stainless alternatives, its near-zero corrosion maintenance and longer service life reduce total cost of ownership for commercial hydrotherapy installations compared with stainless models like Bowman, AquaCal and Waterco. Technically it outperforms others on longevity and chemical compatibility, and is therefore the preferred choice for demanding therapeutic pools and salt-assisted treatments.
