NIMBUS Advanced Process Cooling was established as the cooling systems and solutions research, development, and manufacturing division of EMSCO, Inc., An Inductotherm Group Company with a 40-year history of providing service to the induction melting industry. NIMBUS Advanced Process Cooling manufactures hybrid adiabatic cooling systems in the U.S.A.

VIRGA III Hybrid Adiabatic Cooling Technology:

VIRGA III hybrid adiabatic cooling systems eliminate standing water in favor of a fully closed coolant path, and the intermittent use of fresh water to augment the system's cooling capacity only on the hottest days of the year.

The VIRGA III hybrid adiabatic cooling system releases a fine water spray into the air prior to the air being pulled over the copper cooling tubes - lowering the air temperature and increasing the heat rejection capacity of the unit. The control system cycles individual fans as process water temperature dictates, and ultimately activates the fine spray of water when required. During the colder months, water spray activation is not required and the unit operates as a dry air cooler - eliminating sump freezing and dangerous ice buildup common with traditional fluid coolers.
