Did you know Type III appliances differ from Type II appliances in that they operate in a vacuum on their low-pressure sides and sometimes on their high-pressure sides, which affects what happens when they develop a leak? When a Type III appliance develops a leak in a location that is under vacuum, air and/or moisture leaks in. In this interactive online course, we will cover the EPA 608 Type III certification exam, the techniques that are used to recover refrigerant, evacuation requirements and safety considerations for working with or around refrigerants.

Whenever steam condenses in a process, it creates hot liquid condensate. It is the role of steam traps to remove condensate from steam lines and process equipment with a minimum loss of live steam. The condensate has economic value, so it is typically collected and reused. This module discusses the collection and re-use of condensate in a steam generation system. Three major classifications of steam traps are discussed, including their principles of operation, and their strengths and weaknesses.
