Summer Is a Great Time for Commerical Chiller Tune-ups

If you’re handling the HVAC needs for a government or civic institution, you may know that eventually, your professional chiller is going to require maintenance due to the sheer volume of visitors and guests that your facility hosts on a daily basis. In an emergency situation, this can cause all kinds of on-the-job problems for you and your team, especially since well-being can be tied to the overall safety and security of your building.

Commerical Chiller A/C

As the summer heat rolls around, now is the ideal time to tune-up your commercial chiller HVAC.

To avoid such a scenario, it is always best to take the necessary preventative measures to ensure that your chiller system is running smoothly year-round, guaranteed by performing an annual tune-up. At Brother’s Mechanical Services, we understand that preventative maintenance is the key to any healthy HVAC system, and we’re here to make sure your needs are met. With the weather warming up, there is no better time to check your chiller and give it the needed check-up than during the early summer months. Here are the top 5 ways to be sure that your chiller is ready for the summer heat!

Check Operation of Starters and Motors

All industrial HVAC systems require efficient operation of their starters and motors. To check them properly, test the safety and sensor calibrations on microprocessor controls, followed by a proper check of all electrical connections, wiring, and switchgear related to the chiller for hot spots and worn contacts. Test electrical motor windings for insulation resistance to ground and winding-to-winding to be sure there are no insulation issues. Finally, take a look at the shaft seal of open drive motors for possible refrigerant leaks, and clean motor cooling air vents.

Treat Condenser Water To Prevent Possible Corrosion

Corrosion can be an issue that leads to larger problems. To keep that in check, remember that all condenser water loops using open cooling sources require proper water treatment to avoid scale, corrosion and toxic biological growth — all of which can have negative health effects on visitors to your building or facility.

Lower the Temperature of Your Entering Water

As an important preventative measure, lowering the temperature of the entering condenser water. In many government and commercial building systems, the operator will usually lower the chilled water set-point to bypass air handler deficiencies, curing the symptom but not the problem.
