Trane CenTraVac™ Water-Cooled Chiller CVHF - 190-320 - 215 - 050S / 050L

Use a non-destructive tube test to inspect the condenser and evaporator tubes

Tube test performed on condenser and evaporator tubes?

It may be desirable to perform tube tests on these components at more frequent intervals depending upon chiller application

This is especially true of critical process equipment

Ask your Sales account manager for a copy of engineering bulletin (CTV-PRB024*-EN) for clarification of the role of eddy current testing in chiller maintenance by providing information about eddy current technology and heat exchanger tubing

Sign off on the tube maintenance

Operate the tang operators manually and check for any abnormalities

Drain contents of the rupture disk and purge discharge vent-line drip-leg into an evacuated waste container

Do this more often if the purge is operated excessively

Apply oil to any exposed metal parts to prevent rust

Shut down the chiller once each year to check the items of Optional Accessories

If applicable, lubricate factory-installed gantries

After the first month of operation, inspect Heresite® or Belzona® coated waterboxes; thereafter, inspect as needed

Inspect and lubricate hinged waterboxes

With water flow sensing option, bleed tubing from waterboxes to transformers

Sign off on the yearly optional accessories maintenance

Inspect for fouling and scaling in tubes

Check operation of condenser water flow sensing device

Factory recommendation to eddy current test tubes every three years

Sign off on the condenser inspection

Test appropriate sensors for accuracy

Ensure sensors are properly seated in wells with thermopaste installed

Check evaporator leaving water temperature low temperature cutout setpoint

Condenser high pressure switch check-out

Check adjustment and operation of the inlet guide vane actuator
