Strictly Refrigeration,” presented by Bill Sammons, CMS, of the Bill Sammons Co.—This session is designed to point out the differences in air-conditioning and refrigeration systems, the way they operate and the parts that are involved in a refrigeration system that are not involved in A/C. As an example, refrigeration systems require some sort of a defrost system where A/C does not.  The operating temperatures are different, and they require some different parts and controls to accomplish this.  Have you ever heard of a reverse acting high pressure control? This will be discussed and other various parts and controls will be explained. Session Level: Intermediate

Session Level: Basic-Intermediate

“Facility/Contractor Coordination in the Industrial Environment,” presented by Vern Sanderson of Wagner-Meinert/RETA— As contractors are asked to perform larger and more complex service and construction projects, communication and the management of expectations becomes more important. Coordination determines whether or not the job is ultimately profitable most times. Through our discussion we will look at some of the pitfalls, and some of the tricks to good communication and coordination. Session Level: Basic
