Portable Humidifiers Essential Service & Maintenance

It’s important to perform regular maintenance and servicing on your Defensor humidifiers to ensure they are working their best and keeping the environment at the preferred humidity.

Novatron Scientific has a team of qualified, experienced engineers who will visit your premises to carry out preventative maintenance and make sure that your portable humidifiers remain safe, efficient and reliable.


Regular service, cleaning and replacing consumable parts is essential to get the best from all types of humidifiers as dust and lime-scale are always a problem.

Our service contract provides you with support to protect your investment. It guarantees a review twice a year, and the replacement of any necessary parts.

Preventative Maintenance

Planned maintenance of your humidifier will ensure reliable and safe operation all year round and reduces the risk of it failing.

We recommend at least two planned inspections each year. One should be during the autumn, before the weather turns cold. The other should be early spring to check that the humidifier is still working efficiently following the higher use over the colder weather.

Portable humidifiers are relatively simple and low cost to run but they will accumulate both lime-scale and bacterial/fungal build-up if they are not cleaned and maintained regularly.

Our preventative maintenance contract includes top to bottom inspection and maintenance of your humidifier as well as training for your on-site staff.
