ENGINEERED FOR EFFICIENCY
A VERSATILE RANGE USING PROVEN
DESIGN & CONSTRUCTION
TECHNOLOGY

Thermex swimming pool heat exchangers are based directly on our established range of marine oil coolers.

Using the same proven design and construction technology, our versatile range offers an energy-efficient and economical solution for maintaining near constant year-round water temperatures in swimming pools, spas, plunge pools, hot tubs and hydrotherapy pools, along with aquatic pools and ponds.

We have 40+ years of engineering experience and an outstanding reputation for manufacturing reliable swimming pool heat exchangers which are compatible with most heating systems.

This includes solar, heat pump (air or ground), and direct resistance heating systems, as well as traditional gas or oil burning boilers.

Standard Copper Nickel

Our standard range of swimming pool heat exchangers feature extruded aluminium bodies, gun metal headers and 90/10 cupronickel tube stacks, which are ideal for chlorinated water with free chlorine levels of 1 to 3 ppm with a pH level of 7.2 to 7.8.

Features

90/10 cupronickel tube stack

Floating tube stack for easy inspection and maintenance

6 standard models ranging from 9kW to 730kW heat transfer

Suitable for pools up to 250,000 gallons

Compatible with salt and sea water applications

Thermostat port options available

Easy installation – wall or floor, horizontal or vertical

High Performance Titanium

Extruded aluminium bodies with an anodised finish, glass-filled nylon headers and a highly corrosive resistant, floating, titanium tube stack all add up to a premium product you can rely on.

Fit and forget directly into most pool plant-room pipework via the ABS solvent weld connector ports will help improve performance and reduce maintenance costs.

Due to its low thermal conductivity, titanium tube stacks offer increased thermal transfer efficiencies while operating with higher flow rates when compared to traditional CuNi tube stacks. This results in a more compact, cost-effective unit offering improved performance heating a body of water with a significant reduction in energy costs.

With the ability to operate in virtually all leisure pool water types, including fresh water, seawater and saltwater chlorinators with chlorine levels of up to 15 ppm, titanium has the added benefit of eliminating the occurrence of seawater induced electrochemical, galvanic corrosion. This extends tube stack life span indefinitely, offering outstanding longevity and unrivalled performance.

Features

Titanium tube stack for ultimate reliability and longevity

Floating tube stack for easy inspection and maintenance

3 standard models ranging from 15kW to 45kW heat transfer

Maximum Operating Pressure: @ 6 Bar both sides

Suitable for pools up to 28,000 gallon water capacity

1 ½” ABS solvent weld connector ports to minimise risk of any pressure drop

Compatible with seawater and saltwater chlorinators

Integrated temperature sensor port

Easy installation – wall or floor, horizontal or vertical

From cylinder extrusions to tube stacks, headers to port sizes – we utilise a modular approach to component configuration which allows flexible versatility and cost-effective solutions to heat exchanger design – be it a standard ‘off-the-shelf’ unit or a customised solution.

Product Range

Finned Tube Heat Exchangers

With over 45 years of innovative design and manufacturing expertise, Thermex has developed a range of high-performance finned tube heat exchangers. Our finned tube heat exchangers are designed to significantly increase the tube stack surface area available for thermal transfer by up to 400% when compared to units of a similar size. This results in a compact and highly efficient heat transfer solution.

Swimming Pool Heat Exchangers

Thermex swimming pool heat exchangers are based directly on our established range of marine oil coolers.

Charge Air Coolers

Used on turbocharged or supercharged (forced induction) internal combustion engines (ICEs) to improve volumetric efficiency, charge air coolers (CAC) increase intake air-charge density through isochoric cooling.

Marine Oil Coolers

Combining efficiency and reliability, the Thermex range of shell and tube marine oil coolers ensures optimised thermal transfer of excess heat generated by on-board fluid power systems typically used in steering systems, deck equipment and water-cooling solutions required for marinised engines.

Hydraulic Oil Coolers

The Thermex range of shell and tube hydraulic coolers are essential for efficient dissipation of excess heat to ensure the optimum performance of any hydraulically driven industrial and process equipment.
