ALFABIZ HEAT EXCHANGERS

Alfa has a complete line of shell and tube heat exchangers for solar pool heating systems or boiler heating systems. To promote longevity of all the system components, instead of placing chlorine or salt pool water directly through the solar panels, utilize an external Alfa heat exchanger for a more versatile, robust solar design.

Our pool & spa heat exchangers are defined by their distinctly unique tube designs, either corrugated straight tubes or smooth coiled tubes, which were engineered to maximize the use of solar or boiler energy; thus increasing the overall thermal efficiency of the system.

Available in a broad range of sizes, and a selection of different materials to suit the specific requirements, these popular Alfa models are the perfect solution for any pool, spa, and hot tub application.

Alfa Pool & Spa Heat Exchanger is fully constructed with pressurized shell and helix corrugated inner tube. This ensures high velocities inside the unit making pool & spa heat exchanger a very reliable, efficient and cost effective way to transfer heat indirectly between any hot water circuit and any pool or spa circuit, besides other application.

We have a large range of heat exchangers well suited from small spas up to Olympic size pools, our units are rated from 55,00 to up to 4,500,000 BTU/H

With high heat transferring efficient heat exchanger tubes and smooth shell, it ensures high velocities inside of the unit making the heat exchanger a very reliable, efficient and cost effective way to transfer heat indirectly between any boiler or solar heating circuit and any pool or spa circuit, besides other applications.

Note:

  • For occasional (holidays & weekends) use pools we recommend a 2x output multiplier to obtain a 2°F/hr heat up rate;
  • Nominal values are based on 60°C temperature between incoming heating and heated water.
