Summer heat may have come to an end (in some areas), but air conditioning systems are a necessary need year round for a number of industrial and commercial applications. Unlike the air conditioning unit you’d find at your home, large office building and industrial plants require a much larger scale A/C machine. In many cases, these air circulation and conditioning machines function with heavy duty chillers or cooling towers, and that requires extra care and monitoring to keep them running in good condition.
With energy such a highly charged subject these days, it’s important to know how and where different forms are being utilized. Take cell phone towers — companies today are switching from backup batteries and electrical generators to longer-lasting, lower maintenance hydrogen fuel cells. While the benefits are high, hydrogen is still highly combustible and therefore equipment designers and installers must meet additionally demanding requirements. That increases the reliance on products like the High Pressure Excess Flow Valve (HPEFV) from ChemTec.
Sometimes using standard items out of the product catalog makes life complicated. For example, a ChemTec customer wanted to install an excess flow valve (EFV) in a system with 2” diameter piping. The problem was, the EFV meeting the performance requirements had 3/4” diameter ports. This left them with two choices: reduce their pipework to the required diameter, or request a custom EFV with the performance of the standard unit but 2” ports.
