Customized supplier shell and tube heat exchanger for swiming pool and spa.
Our heat exchanger fully constructed by stainless steel 316L OR Ti shell and tubesmaking Pool & Spa Heat Exchanger a very reliable and effective way transfer heat indirectly between any boiler and pool or spa circuit, besides other application
Mounting
The method of mounting used is totally responsibility of the installer. The units are designed for both horizontal and vertical mounting, it is recommended to always install the unit with a mounting bracket fixed to a wall, or ceiling or floor to prevent hammer heads or vibrations which could damage the unit, the use of expansion joints on the boiler circuit is recommended.
nstallation Instructions
Important: Always install the pool & Spa heat exchanger in a counter flow pattern, as shown in the following figure.
Pool & spa heat exchangers should be installed downstream of the filtration and pumping equipment. The boiler water must be assisted and the usual precautions taken to prevent air locks. The pool water pump should be controlled by the thermostat in the pool pipe work before the heat exchanger and set at the required temperature.
Operation instructions
It is important that these instructions are followed to prevent any corrosion or erosion of Stainless / Titanium pool & spa heat exchanger.
- Operate the unit under the following design parameters shell/tube side pressure: 6 bar (87 psi), Temperature: -5ºC (23ºF)-200ºC (392ºF)
- Install unit before chlorination device.
- Start-up
- Valves should be opened gradually to achieve a steady increase in flow and pressure into the unit
- The cold (heated) fluid should first enter in to the system
- The hot(heating) fluid, water or steam, should be gradually brought into the system.
- Check all connections for leaking.
- Shut-Down: shut down hot fluid side first, then the cold fluid side.
- (For Stainless heat exchanger only) Always keep PH within correct levels. The ideal pool PH should be kept between 7-8. It is extremely important to avoid PH to fall below 7.2 or above 7.8. you must check daily. Modify your pool condition if necessary.
- You must ensure that the chlorine levels are in the range recommended by your pool chemicals supplier and they are aligned to your specific needed.
- If you have installed a by-pass fitted to the heat exchanger circuit, it is important that any valve is corrected positioned to allow the recommended pool water flow to pass though the heat exchanger unit.
- The filter should be checked regularly,especially sand filters, this type of filtration if working improperly will allow sand to pass around the pool circuit causing erosion of the heat exchanger and other components of the system as well.
