HCG Associates, a provider of process safety management (PSM) compliance assistance, completed the acquisition of Protexus. Houston-based Protexus is a regional provider of PSM solutions and mechanical integrity services for anhydrous ammonia refrigeration systems, primarily in the South and Midwest. Both companies serve customers in industrial refrigeration, food and beverage, manufacturing, cold storage/distribution and critical environments.

Deborah Spradlin, former president of Protexus, will serve as a regional director at HCG and remain active in the management and integration of the two businesses.

Included in the acquisition and a new benefit for existing HCG customers is access to Protexus’ cloud-based PSM Pro software, which allows users to manage and document PSM and risk management plan (RMP) programs.
