System Hygiene

Humideco takes a responsible approach to the design of all Eco-Mist systems, particularly where operational hygiene is concerned. Although Eco-Mist systems are designed to operate from chlorinated town mains water supplies, they incorporate hygienic features that exceed the guidelines laid down by the UK’s Health and Safety Executive, as well as other International standards. Every system incorporates micro-fine water filtration, plus UV (ultra-violet) sterilisation, as well as purge cycles that keep water moving at times when there is no humidification demand. These measures are incorporated into the control system; if a fault should occur, the system will shut down and show a red light on the filtration icon on the control unit display.

The high quality ultra-violet sterilisation system used in the Eco-Mist control unit features a large stainless steel chamber, containing the lamp, designed to generate UV-C light at the optimum wavelength of 254 nm. Combined with the long exposure time within the chamber and the effective pre-filtration, to prevent “shading,” this ensures a very high efficacy. Ultra-violet sterilisers work by causing damage to the nucleic acid of microorganisms by forming covalent bonds between certain adjacent bases in the DNA. The formation of such bonds prevent the DNA from being able to reproduce. In fact, when the organism tries to replicate, it dies.

In addition, water is not left in the humidification units, or feed pipework when the system shuts down. This prevents any possible risk associated with the use of standing water when the system is returned to service.

Good system hygiene is also a factor of routine service and monitoring, which should usually take place every 6 months. Humideco engineers will sample, test and report on system water quality as part of routine servicing.
