HVAC systems play a crucial role in many industrial cooling applications. These systems – composed of cooling towers, chillers and air handlers – are used to cool areas where high heat loads can shut down critical processes. This could stem from machinery that generates extensive heat, or where cooling and ventilation are required to protect temperature- and humidity-sensitive equipment.
In the case of a large paper mill operated by one of the world's leading makers of tissue, pulp, paper, and packaging products, a primary cooling tower, along with other HVAC apparatus, is vital to keeping the electrical equipment rooms cooled. These enclosures hold heat-sensitive instrumentation used to monitor and control essential plant operations.
