Evaporative Humidification / Cooling System

SK VAP Principle of Operation

Raising the relative humidity by passing air through a wetted matrix is a simple and safe way to humidify - with the

added benefits of very low running costs and evaporative cooling.

At the heart of the SK VAP is the evaporative module, which is installed in an AHU or duct. Water is supplied to the top

of a highly efficient bonded matrix, which is impregnated with silver for added hygiene. Dry air passes through this

moist material picking up water vapour, raising the humidity as it does so. This process consumes very little energy, far

less than steam humidifiers or even cold water atomisers.

The water that doesn’t evaporate assists in washing the matrix material and flows into a stainless steel tank at the base

of the unit before being re-circulated up onto the matrix again.

As each vertical matrix bank has its own water supply, multi-stage control is an option which individually operates sec-

tions of the system for closer control.

Modular construction facilitates a range of system sizes and efficiencies to match the requirements of individual appli-

cations, and ease of installation, maintenance and replacement should damage occur to any of the matrix casssettes.

To prevent clogging of the humidifier cassettes, the airflow into the module must be filtered to at least 5 micron filtration 

standard.  Finer filtration may be required for hospitals or where air is being supplied to areas where food or electronic

products are being handled.

To prevent droplet carry over an optional droplet separator can be fitted. It is recommended for velocities above 

11.5 ft/s (3.5 m/s)  when the fan is positioned before the SK VAP or velocities above 13 ft/s (4.0 m/s) when the fan is

positioned after it.

For areas of hard water, water treatment is recommended to reduce maintenance requirements.
