  • We are a small HFEA licensed fertility clinic, and we required a service contract for our Class II cabinets and particle monitoring of the background air in our clinical laboratory. We approached CHTS as we had been recommended to them. I was delighted with the efficiency of their customer service, as well as the high standard of technical support we received. We were very impressed by the thoroughness and timeliness of the report following their on-site visit. We feel confident that we have chosen the best company for our needs and would highly recommend them for air quality testing.

  • Crowthorne Hi-Tec Services have provided a service to the East Sussex Trust Pathology department for several years and we have always found their work highly professional. The servicing team are very accommodating regarding dates for the work and the engineers provide an excellent and efficient service.

  • Over the past twenty years, I have been using Crowthorne Hi-Tec Services for the planning of new builds and continuous validation of the Cleanrooms at Xograph Technologies and previously EMS Medical manufacturing sites based in the UK. The advice given during the planning prior to construction and the end result of Cleanroom classification in my opinion has proven to be second to none. My current Cleanrooms operate to ISO 10,000 class 7, which includes a machine processing and a full assembly Cleanroom operate with minimum management required which is put down to the design incorporation airflow ensuring no dead area’s are present. Their engineers are all fully trained and can advise during their routine visit as to potential areas of risk, when changes are forced within the manufacturing environments. I would fully recommend Crowthorne Hi-Tec Services to any present or future prospective Cleanroom room manufacturer.

  •  “The College of Medical and Dental Sciences at the University of Birmingham have been serviced by CHTS for the last 14 years.   The fact that we have not changed suppliers in all of these years, speaks volumes for the service CHTS provide. Their engineers are knowledgeable with the capabilities to develop strong relationships with their customers, their service is trustworthy, they are competitively priced and if emergencies arise they have very good response times.”
