We have been working with Hydro-X for over 2 years initially with our cooling towers then with AHU air hygiene along with using with the training division. The service delivery is top class in all areas site personnel, account managers all backed up with quality reports & certification always delivered without delay. The responsive way any communications are handled by phone or e-mail is exceptional. The training offering is well organised & delivered in such a way as to be informative & engaging we have used both face to face & online. The air & water engineers are knowledgeable & great to deal with. Hence why we would have no hesitation to recommend Hydro-X to others who require the services they offer.
