Training Course: Chillers: Operation & Maintenance of Chilled Water Systems
Introduction
It is imperative that your water-cooling system(s) operates at maximum efficiency. In this hands-on chilled water systems seminar you will receive the critical information needed to increase your system’s reliability.
The chiller is the heart of the refrigeration system which operates best with skilled technicians maintaining it. Gain hands-on practice and knowledge of instruments and test meters. Learn how to collect data and evaluate the chiller operation equipment. Become familiar with approach temperature and to interpret it in terms of the system operation.
