Whitewater are the largest supplier of RO water systems for endoscopy suites in Ireland, providing purified water for washing and final rinsing to automated endoscope reprocessors (AER’s). The high quality and compact ‘Plug and Play’ unit is easy to install. Unlike some other systems, the Whitewater RO does not require additional feed pumps as the unit can operate with low pressure. In most cases softening is not required, avoiding the need to take up additional space with separate water softener units.

We understand the importance of preventative maintenance and service for validation in the hospital environment. Because hospitals are involved in ‘critical care’, it is essential that equipment items that are in the ‘critical path’ are regularly serviced and maintained.

We provide on going support services to ensure that your water systems remain at peak efficiency. All engineers operate to the ISO 9001:2008 standard of quality assurance. We offer full contract maintenance for your systems and can also advise on training for your own staff in data logging and routine maintenance of consumables.

We offer a 24/7 on-call emergency service for hospitals who take out our 12 month service contracts and whose systems are regularly maintained by Whitewater.
