Featured Case Study  Improved Safety with Hands-Free Delivery

A manufacturing plant had been struggling with their chemical inventory control. Additionally, they had an event of introducing the wrong chemicals into storage tanks which caused off-gassing. After some discussions, the client decided to enlist CRB’s Hands-Free delivery service.


I would highly recommend using Chemtron for all water treatment testing and services. We have been very successful using the monthly reports to present to the Infection Control Committee to address legionella and indoor air quality questions. They are truly a partner in the process.

– Director Building Services, a St. Louis-Based Hospital

There was an immediate and sustained improvement over our previous program when we made the switch. Not only did we see a slight cost improvement, but they eliminated a lot of the delivery and performance issues than we had with Nalco/Ecolab. They do a great job with the pathogenic monitoring and the reporting program, and their expertise on biological control, Legionella best practices and ASHRAE 188 is especially valuable to our facility.Having the company based in St. Louis makes it especially convenient. Not only are the reps quick to respond, but we have had chemical deliveries in one day when needed. I don’t have any reservationsabout recommending Jeff and Amy at Chemtron for other hospitals water treatment needs.”
