BOREAS Overview

NIMBUS Advanced Process Cooling's innovative VIRGA X3® and VIRGA III® hybrid adiabatic cooling systems are engineered to deliver safe, dependable, and efficient blue cooling for virtually any application. However, those operating with lower dry bulb temperatures and/or higher outbound process fluid temperatures may wish to consider a dry air cooling system.

NIMBUS provides BOREAS® and BOREAS® V-Series Dry Air Cooling Systems for customers who fit that specific niche.

Like our flagship VIRGA systems, BOREAS systems are designed to deliver years of efficient cooling while minimizing the risk of Legionnaires' disease, conserving water, and eliminating the costly maintenance programs associated with traditional evaporative coolers.
