Great service! I cannot recommend HydroChem Group enough, we have used HydroChem for years now and they have never not been able to help. Great quality products and service to boot! Thanks again guys!

Stuart, M.D. Brown & Co.

Great work on my cooling tower through a very busy summer shut down. Excellent planning, knowledge and execution by HydroChem Group. Couldn’t be happier with the results. Breathed more life into two cooling towers increasing efficiency and reliability.

Simon Howick, Plant Engineer, Pharmaceutical Manufacturer

I have been dealing with HydroChem over the past 6 months, during this period we have had  a first class service from the HydroChem team. HydroChem staff have been a pleasure to deal with and have always done their up most to make sure products are delivered on time. The products themselves have always been high quality and the technical service has been second to none. Going forward I will continue to use HydroChem and the experience they bring.
