The adoption of R290 back then was driven by both environmental imperatives and market consensus. With a Global Warming Potential (GWP) of only 3—1/200 that of R32—it causes no damage to the ozone layer whatsoever.
Meanwhile, it boasts exceptional thermodynamic performance. When combined with inverter technology, its energy efficiency has achieved a leapfrog improvement. The market has long sent clear signals: over 40 enterprises showcased innovative R290 heat pump products at ISH Frankfurt (Germany), and R290 technology is also set to be the focus of the highly anticipated 2025 Aquana LE International Pool & Wellness Exhibition—reflecting the industry’s unanimous recognition of its technical prospects.
For the sector, 2025 marks a critical window of opportunity for R290 deployment. Just as inverter technology drove a $2 billion growth in the pool market a decade ago, R290 is poised to usher in a new era of incremental growth.
As the global green transition advances comprehensively, R290 is no longer an "option" but a "necessity." Guided by a forward-looking vision, Dentwiton has deeply cultivated R290 technology. By providing pool heat pump products that integrate environmental performance, high energy efficiency, and exceptional user experience, it offers future-ready solutions for pool professionals worldwide, leading the new wave of the industry’s green transformation.
