An innovative hot water solution utilizing waste heat from air conditioning and refrigeration systems. Saves up to 40% on energy and reduces CO₂ emissions for sustainable renewable energy.
“Turn wasted heat
into hot water savings.”
A hot water production system that recovers waste energy from air conditioners. Ideal for high-demand businesses such as hotels, resorts, industrial plants, and wellness centers, it reduces energy waste and ensures long-term savings.
➢ Connects the air conditioning refrigerant circuit at the discharge line from the compressor (approx. 90-100°C) to the hot water tank.
➢ After heat exchange, the refrigerant flows back to the air conditioning system for normal cooling via the condenser. The produced hot water is stored in the tank for use.
➢ Heat from the refrigerant is transferred through the heat exchanger to the water in the tank, raising the water temperature up to 70°C.

“Before, we hardly used the pool because the water was quite cold. But after installing the PAC Pooltemper pool heater, my children and I use the pool much more often. We swim more and have many more family activities together.”
“We used to use electric heaters for hot water in the guest rooms. Since the resort switched to PAC Frenergy, our electricity consumption dropped from 880,000 kWh/year to just 171,000 kWh/year.”
“My Koh Chang Paradise Resort has been using PAC Frenergy for over 10 years. Now that I’ve expanded to Koh Kood, I continue to choose PAC products, specifically the latest PAC Hybrid Solar technology—a solar-powered VRF air conditioner. It truly helps us save energy and reduce electricity costs.”
“No more worries with PAC Pooltemper. The build quality is excellent, it’s reliable, and it doesn't require frequent repairs. It’s perfect for our business.”
“At Khum Sameing, we offer a Japanese onsen in a Thai Lanna atmosphere. We installed PAC Pooltemper, which can heat water up to 50°C. For our guest rooms, we use PAC Frenergy and PAC EcoAire, which have significantly reduced our energy consumption. I also chose PAC products for my IWRM water treatment plant in Phan Thong, Chonburi. We are very satisfied with PAC’s innovations.”
PAC is trusted by executives and leading corporate clients at over 500 locations nationwide.
