When hundreds of ammonia refrigeration engineers, manufacturers, contractors, and end users gather in one place, technical talk is sure to follow.

Techs may not see the importance of the service ticket, but they should, since it can be an accurate reflection of him and his work. 

Beyond making refrigeration equipment and refrigerant gases, manufacturers of such products are also involved in developments within the industry that show global sweep. Here are several recent announcements involving manufacturers familiar to contractors and service technicians.
