The role of swimming pool heat exchangers

Swimming pools are significant investments that deserve sound engineering and proven products to ensure the desired outcome is achieved. Water temperature plays a large part in ensuring the safety and comfort of the pool. Alfa Laval heat exchangers provide the ultimate solution to deliver on this.

Key functions and aspects of pool heat exchangers

In some large aquatic centres for example, stand-alone heat pumps may be installed for the sole purpose of producing heat for the swimming pools. However in the majority of applications, the heat required for the swimming pools is drawn from the buildings central heating system. In either scenario, a heat exchanger is necessary to link the swimming pool’s circulation system and the heat source.

In the past this was often achieved with shell-and-tube heat exchangers. But the thermodynamic advantages and compact design of plate heat exchangers offers a superior solution to swimming pool applications. Therefore the 2 best options to consider for swimming pool applications are:

  • Alfa Laval gasketed plate heat exchangers
  • Alfa Laval brazed plate heat exchangers

What pool heat exchangers must be made from

The materials of construction are a key factor to ensuring you get optimal performance and lifespan out of the heat exchanger. Whether it is a salt water pool or a chlorine pool, the chemicals used produce a harsh and corrosive environment for pumps, valves and heat exchanger components. This is particularly so for the chlorides in the water, which are highly corrosive to stainless steels and nickel alloys.

When in direct contact with pool water, heat exchanger plates must be of titanium construction, because unlike stainless, titanium possesses qualities that grant it high resistance against the corrosive nature of aquatic environments. Titanium, combined with carbon and nitrogen will reduce susceptibility to intergranular corrosion and pitting.

Furthermore, the titanium plates used in Alfa Laval heat exchangers include a permanent thin oxide film that provides strong resistance against corrosion and a high affinity to both oxygen and moisture in the atmosphere.

Frequently asked Questions

Titanium, because it will protect against the corrosive chemicals used in swimming pools, thereby ensuring long life span and optimum efficiencies in operation.

The higher the flow rate through the heat exchanger, the less maintenance will be required because the high velocities will push through debris or at least reduce the formation of scale deposits internally. In essence it works to be self-cleaning to a degree.
