How to Conduct Titanium Heat Exchanger Leakage Check?

Refrigerant Water Leakage Check

 

Connect the heat exchanger with water pipes and charge water pressure up to 4 bar to see if water leaks from the PVC shell. 100% check on every heat exchanger with 4 bar water pressure and 6 bar as random check on some pieces.
P.S.: Water pressure for normal pool system is 2 bar only.

A round green QC passed sticker will be put on the heat exchanger to show this is QC passed.

A green square sticker will be put on the heat exchanger to show this passed 6 bar randome check.

Flow switches been checked before they are installed on the heat exchangers so green stickers are also on each flow switch here.

Refrigerant Circuit Leakage Check

Tianium heat exchangers are kept at high pressure of nitrogen in the titanium coil inside for 48 hours to check refrigerant circuit leakage before being assemble, 100% checked.

After 48 hours workers will unscrew the gas valve to check if any gas pressure inside the titanium coil to find the leaks. 100% checked. Those fail will be rejected to suppliers.
