Open Recirculating System Treatment

The open recirculationg system is perhaps the most commonly encountered cooling system in the industry. These units are basically open to the atmosphere, where heat is expelled through the process of evaporation. Evaporation and the cooling effect it brings lowers the temperature of the bulk water, which circulates through various types of heat exchange equipment, picks up heat, and returns to the “open” tower to repeat the cycle.

Nalco offers a full line of products for open recirculating cooling applications. Many products in our 3D TRASAR technology product line are based on our patented all-organic technology. With 3D TRASAR technology control, your system is monitored and feedrates are controlled for optimal, cost-effective performance.
