I have a trane chiller model # CVHE500 that has a problem with surging after initial startup. When I switch over to this chiller, as soon as the vanes start opening the chiller starts surging very loudly.

These two types of chillers have completely different control panels and sequences of operation, both of which will be covered in depth, along with reports, programming, and troubleshooting. Also, startup and shutdown procedures and preventive maintenance items will be covered. We will also discuss how to log these chillers and get the information needed to maintain efficient operating machines. A section will be devoted to refrigerant management and conservation procedures, including transferring or recovery of high-pressure refrigerants. Audience: This class is intended for building operators, facility personnel, and property managers. Tuition: $450 per student (includes breakfast and lunch, and all training materials) Discount: $50 discount for each additional student from the same company (only applies to same class, same company).
