As well as cleanliness, heating and cooling, another important aspect of air quality is moisture content.
We have many years of experience with controlling humidity. Maintaining a minimum humidity level is relatively easy and we have a full range of humidifiers to choose from.
Traditionally electrode boilers are very popular methods of introducing humidity because they don't affect the temperature within the room and are easy to maintain by either replacing or rebuilding cylinders.
Resistive element humidifiers are more expensive but give more accurate and responsive control when this is required.
We also have other types of humidifiers including live steam and cold water models.
