The importance of commercial hot water system maintenance

commercial hot water system maintenance

Has the UV system on your commercial hot water system been serviced lately?

To maintain optimal performance of any commercial HWS, and to ensure the UV system is achieving the correct level of disinfection, it’s important to service it regularly.

Each component of your commercial hot water UV system has a recommended replacement schedule to ensure optimal performance.

A commercial hot water UV maintenance schedule

UV lamps

Recommended replacement time : annually (8,000 – 16,000 hours depending on type)

UV disinfection organisations promote their UV lamps as having a particular lamp life.

Although a UV lamp may appear to be working past its lamp life, its disinfection capability decreases due to a reduction in generated UV-C light. In general, a UV lamp’s intensity at the end of its lamp life has been reduced by 20% compared to a new lamp.

In addition to UV lamps being replaced, controller lamp timers need to be reset and UV intensity monitors need to be re-calibrated where applicable.

Quartz sleeves

Recommended replacement time : every 2 years

The condition of a quartz sleeve plays a vital role in how well the UV light can penetrate the water or liquid.

A dirty quartz sleeve blocks UV light from reaching the water, reducing the UV intensity in the UV reactor, resulting in a decreased UV dose. This increases the likelihood of pathogens passing through the UV reactor and not being adequately treated which is especially dangerous in potable or food and beverage applications. Quartz sleeves may become dirty to the point that they cannot be cleaned after 2 years and they also become brittle.

It must be noted that quartz sleeves should be inspected at regular intervals during the initial operation of a new hot water system. This will give an indication of the cleaning frequency required and will establish if further pre-treatment is required to prevent quartz sleeve fouling. Another indication of a potentially fouled quartz sleeve is a UV intensity monitor. A drop in UV intensity may indicate a dirty quartz sleeve.

Quartz O-ring seals

Recommended replacement time : annually

The O-ring that creates the seal to prevent water from entering the quartz sleeve needs replacing each time the quartz sleeve is removed for cleaning.

This should be annually as a minimum requirement.

Failing to replace the O-ring will increase the chances of water reaching the lamp, resulting in lamp failure.

Depending on the system model, there may also be additional service actions required such as replacing quartz wiper blades. Manuals provided for each UV system model must always be followed.
