Why Vapac

The Eaton-Williams Group has been manufacturing humidification equipment since 1975 when the first Vapac designs were formulated. Since then the continued input to research and development has identified the company as one of the leading designers and developers of humidification equipment, with 60% of production being exported, throughout the world.

Since the first units were introduced the Group has amassed a considerable depth of knowledge that continues to provide all Consultants, Designers, Contractors and Users with the assurance that the Group has, not just the experience available to address any humidification problems, but the equipment to resolve those issues.

Why Humidify

An atmosphere with low humidity can have a detrimental effect on both equipment and personnel. Below 35%RH equipment and machinery with moving parts can be very susceptible to failure due to high Voltage static electrical discharges. Not only can the human body become the painful conduit for static electrical discharges but can also be discomforted in a low humidity environment by dry skin, eyes, throat, and nasal passages. Raising the humidity levels above 35%RH can help to minimise these problems.

Why Do I Need More Than Air Conditioning?

The process of Air Conditioning involves sensible and latent cooling in varying proportions. The latent proportion is responsible for the removal of moisture from the air, causing the controlled area to become dry. As a rule of thumb every kW of cooling removes approximately ½ kg/hr of moisture, this should be replaced by introducing additional humidification.

How is Performance Affected?

The suggestion has already been made that a dry atmosphere can cause discomfort to the human body in the form of dry skin, eyes, nose and throat as well as static discharge, which can be very painful, and bring about a decline in individual and collective performance. In addition however, research has shown that airborne contaminants, including bacteria and viruses, can travel further and faster through a dry atmosphere. Combining the potential rapid distribution of bacteria with personnel having dry and susceptible bronchial passages can lead to, and assist, the spread of colds and flu through the working environment. The performance of contact lens wearers could be amongst the first to decline, because of low humidification levels, as the contact lens sits on a microscopic film of moisture directly onto the eye. Should this film of moisture be lost to a dry atmosphere then discomfort will be immediate.
