Globe's Karl Wiegand, a Technical Education and Research Engineer at Globe, contributed an Op-Ed to guide sprinkler installers on the merits of low Vs. high pressure approaches in dry systems.
"High pressure and low pressure dry pipe systems both have advantages and disadvantages depending on the sprinkler systems in which they are being used. Individual sprinkler systems may have attributes that would favor either system.Typically, if the system is one where the direct route to the outlet requires a large portion of the system to be filled, a low pressure system is favorable. Conversely, if the direct route to the outlet doesn't require a large portion of the system to be filled, a high pressure system is favorable. It is important to remember with these systems that there is no "better" way. There is simply a way that is more appropriate for the situation at hand."

The Worthington family continues to own and operate Globe, under the leadership of Steven Worthington and a team of some of the industry's most seasoned professionals.
