SKVF - Evaporative Cooler


SKVF - Evaporative Cooler

Cooling is a breeze

Neptronic’s SKVF Evaporative Cooler is engineered and built to offer maximum comfort in large scale applications by providing adequate humidification and cooling. In hot applications, this cooling can greatly contribute to process efficiency by enhancing worker productivity, contributing to product quality and reducing energy consumption.

Our SKVF uses energy-efficient modulating fans to circulate outdoor fresh air or indoor recirculated air. It cools dry air when it passes through the wet media to make the water evaporate, which then raises the humidity level. Moreover, our unit cools the air due to the energy transfer generated by the water evaporation.

The SKVF’s controller can be configured with either temperature control for a cooling application or humidity control for humidification. It allows you to temper industrial and commercial indoor areas where heat build-ups could be unfavorable to occupants, production and material goods.
