Stainless Steel Pool & Spa Heat Exchangers



Our heat exchanger fully constructed by stainless steel 316L shell and stainless steel 316L tubes making Stainless Steel 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.

Installation 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.

  • A、Operate the unit under the following design parameters shell/tube side pressure: 6 bar (87 psi), Temperature: -5℃ (23℉)-200℃ (392℉)
  • B、Install unit before chlorination device.
  • C、Start-up
  • 1.Valves should be opened gradually to achieve a steady increase in flow and pressure into the unit
  • 2.The cold (heated) fluid should first enter in to the system
  • 3.The hot(heating) fluid, water or steam, should be gradually brought into the system.
  • 4.Check all connections for leaking.
  • D、Shut-Down: shut down hot fluid side first, then the cold fluid side.
  • E、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 on a daily basis. Modify your pool condition if necessary.
  • F、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.
  • G、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.
  • H、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.
  • I、It is important that the correct chlorine dosage is added to the pool. To allow proper dispersion of this chemical into the pool, distribute evenly in the different area of it, do not does in one area only as this will create highly acidic areas which can cause irreversible damage to the heat exchanger.
  • J、Keep pool free from leaves and other debris, all organic matter can decay an increase the pool PH causing damage the unit.
  • K、It is important to winterize properly if the pool is exposed to winter conditions, we recommended fully draining down the heat exchanger or removing it completely from the installation though the duration of the shutdown period, otherwise icing the unit would damage the heat exchanger.
  • L、Always choose harmless cheaning liquids if needed and clean carefully.
  • M、Stainless steel pool & spar heat exchangers are not suited for saline or sea water environments

N、Chlorinator should be in optimal working conditions.

 

Quick selection of stainless steel pool & spa heat exchangers
 

Note:

    1、For occasional (holidays & weekends) use pools we recommend a 2X output multiplier to obtain 2℃/h (2℉/h) heat up rate.

2、Nominal values are based on 60℃ temperature between incoming heating and heated water.

WARNING
The following fluids are prohibited for use as a flushing agent for stainless steel pool & spa heat exchangers.

  • 1、Hydrochloric acid up to 0.1% concentration
  • 2、Solutions that contain MCI
  • 3、Chlorides (MgCl2, NaCl between 0.01-1%, CuCl up to 1%, CaCl2 from 5% to saturation)

4、Any fluid that will deposit alkaline residue or phosphorous.

 

IMPORTANT！！！
IT IS PURCHASER’S RESPONSIBILITY TO ENSURE THAT ALL FLUIDS IN CONTACT WITH THE PRODUCTS ARE COMPATIBLE WITH THE CONSTRUCTION MATERIAL OF THE PRODUCT. THIS INCLUDES OPERATIONAL FLUIDS AND CLEANING FLUIDS. CORROSIVE ENVIRONMENTS ARE OFTEN A COMBINATION OF CHEMICAL LEVELS, FLOW RATES, AND TEMPERATURES. FAILURE TO ENSURE THIS WILL RESULT IN DAMAGES TO THE PRODUCT.

IF ANY OF ABOVE CONDITIONS IS NOT FULLY COMPLIED THE WARRANTY OF THIS UNIT IS VOID.
Technical or commercial considerations may, from time to time to alter the design, performance and dimensions of the equipment and the right is reserved to making such changes without previous notice.
