A closed-circuit cooling tower system for water, oil, and process fluids that provides efficient heat transfer. Features a corrosion-resistant structure, low-noise operation, and reduced long-term maintenance requirements.
Closed Loop Cooling Tower – High Efficiency, Low Noise, Anti-Corrosive, Long Service Life
A Closed Loop Cooling Tower is a closed-circuit cooling system available in GHM (Cross Flow) and GTM (Counter Flow) models to support applications requiring stability and durability in heat dissipation.
Dissipates heat from water, oil, and process fluids through a closed-loop heat exchange coil system.
Ideal for large-scale HVAC systems, data centers, industrial plants, and machinery requiring continuous cooling.
Provides stable operation, saves installation space, reduces corrosion issues, and extends the lifespan of the cooling system.
Available in cooling capacities ranging from 6 to 366 tons of refrigeration to suit the specific size and requirements of each system.
Delivers high heat exchange efficiency with stable and continuous operation.
Constructed with corrosion-resistant materials such as stainless steel and alloy-coated steel for long-term durability.
Equipped with direct-drive fans and water pumps designed to reduce vibration, ensuring low noise pollution.
Reduces algae growth and clogging with air inlet louvers designed to block sunlight and prevent debris from entering the system.
Designed for minimal installation space; the GTM model is particularly suitable for projects with space constraints.
“The system operates by drawing in cool outdoor air to exchange heat with water and fluids
within a closed-loop pipe system, rapidly and continuously transferring heat to the atmosphere.”
Cooling systems for buildings, HVAC systems, and data centers.
Cooling systems for food production lines, chemicals, and metal parts.
Heat dissipation for generators, transformers, and heat pumps.
Cooling for furnaces, air compressors, and hydraulic systems.
"For me, family time is always precious. Choosing to install PAC Pooltemper was the perfect solution. The problem of water being too cold is gone, as the unit can adjust for both warm and cool water in one system. Most importantly, my daughter loves it. Installing this unit has truly fulfilled our happiness and created perfect moments for our home."
“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 many more family activities together.”
“I previously used Frenergy at home and saw real electricity savings, so I decided to use it for my hotel. It has made the hotel's hot water and energy management much more efficient.”
“Previously, we used electric heaters for hot water in the guest rooms. Since the resort switched to PAC Frenergy, electricity consumption dropped from 880,000 kWh/year to only 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 energy and electricity costs.”
“No more worries with PAC Pooltemper. The machine quality is excellent; no breakdowns or frequent 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°C. 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.”
Over 500 organizations nationwide choose PAC solutions for hospitals, hotels, industries, and various other sectors.
