Safety Control System Standards: Comparing SIL, PL & Categories
Three primary standards are in place that define the level of a Safety Control System (SCS): Safety Integrity Level (SIL), Performance Level (PL), and Category Architecture. In the February issue of Hixson’s From Experience newsletter, we look at the origin of these different definitions and how they correlate to each other. Read the issue today!

Read moreNitrogen vs. Compressed Air for Dry Sprinkler Systems
Many facilities use compressed air for dry sprinkler systems, due to convenience and a lower initial investment. However, compressed air is also a common failure point for these systems, as its use can lead to pinhole leaks. Since these leaks can compromise entire sections of the dry sprinkler system, daily operations must be shut down […]

Throughout the food processing industry, propylene glycol is used in process heat transfer coolant systems when direct cooling with primary refrigerants is not acceptable, and the use of water alone would be at risk of freezing. After system maintenance or repairs, the propylene glycol and water concentration must be replenished in the system. Yet over […]
Read moreSix Signs Your Facility May Need a Wastewater Pretreatment System
Wastewater pretreatment is the process of removing pollutants from a facility’s wastewater to bring it from industrial levels of pollution (several thousand mg/L) closer to the more common residential levels of pollution (a couple hundred mg/L). At manufacturing plants, typical methods of wastewater pretreatment include equalization, pH adjustment, or pollution reduction. Of course, not every […]
