An innovation producing high-temperature hot water at 60-65°C by extracting heat from the surrounding air. It saves up to 75% energy (using 4 times less electricity than conventional heaters) while efficiently providing cool air to the surrounding area.
“Turn ambient air into high-temperature hot water and massive energy savings.”
A Heat Pump Water Heater designed for large-scale, high-temperature hot water production by absorbing heat from the air. Ideal for businesses with high hot water consumption, it provides a comprehensive renewable energy and cost-effective solution.
Absorbs thermal energy from the ambient atmosphere to produce hot water at temperatures of 60-65°C.
Hotels, resorts (with high water demand, e.g., rooms with bathtubs), industrial plants, and hospitals.
Reduces hot water electricity costs by 70-75% compared to conventional electric heaters, plus provides free cool air for the area.
Save up to 4 times more on electricity
than conventional water heaters.
Receive free circulating cool air
to help regulate the surrounding temperature.
Capable of producing hot water
at temperatures up to 60-65°C.
Can replace or supplement
existing tanks immediately.
➢ The PAC Heat Pump absorbs heat from the atmosphere through an Evaporator Coil, causing the refrigerant to change from a liquid to a gas, which is then sent to the Compressor.
➢ The compressor compresses the refrigerant, increasing its pressure and temperature.
➢ The heated refrigerant is sent to a Heat Exchanger to transfer heat to the water system, producing hot water at temperatures up to 60-65°C.
➢ Transfer to a Water Tank to store hot water for future use.
“PAC Heatralized absorbs heat from the surrounding atmosphere to generate high-temperature hot water, cutting energy costs by up to 75% and providing free cool air as a by-product.”
Centralized hot water systems for hotels, or individual hot water units for villas and bungalows with bathtubs.
Hot water for patient rooms, spa businesses, and hydrotherapy systems.
Industrial plants requiring large volumes of hot water, replacing existing electric boilers to reduce energy consumption.
Shower facilities in clubhouses and golf courses.
“Previously, we hardly used the pool because the water was quite cold. But after installing the PAC Pooltemper, my children and I use the pool more often. We swim more frequently and have more activities to do together as a family.”
“Previously, we used electric heaters for hot water in the guest rooms. Since the resort switched to PAC Frenergy, electricity consumption has dropped from 880,000 kWh/year to just 171,000 kWh/year.”
“My Koh Chang Paradise Resort has used PAC Frenergy for over 10 years. Now that I have expanded to Koh Kood, I continue to choose PAC products, selecting the latest technology: PAC Hybrid Solar. It is a solar-powered VRF air conditioner that truly helps us save on energy and electricity costs.”
“No more worries about any issues with PAC Pooltemper. The machine quality is excellent; no breakdowns or nagging repairs. It is perfect for our business.”
“At Khum Sameing, we have a Japanese-style onsen in a Thai Lanna atmosphere, equipped with PAC Pooltemper which can reach water temperatures up to 50 degrees. In the guest rooms, we installed PAC Frenergy and PAC EcoAire, which have helped us save a lot of energy. Additionally, I chose PAC products for my IWRM water 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.
