DryTec™ Cooling Water Disinfection System

Industrial operations depend on reliable water treatment systems to prevent microbiological growth in their cooling towers. Calcium hypochlorite is a highly concentrated source of chlorine in solid form and an attractive option for treating cooling tower water.

The DryTec disinfection system from Solenis is designed specifically for cooling water treatment, making it possible to deliver liquid-available chlorine that controls bacteria and algae and prevents organic contaminants. This solution brings together a next-generation feeder and EPA-registered dry-formulated briquettes in an integrated system that eases containment challenges, mitigates risks from accidental release and reduces costs.

Facilities that use the calcium hypochlorite-based DryTec disinfection system realize a number of benefits:

  • Consistent chlorine production for reliable disinfection
  • Minimized storage requirements
  • Dry formulation for shelf stability and easy handling
  • Reduced shipping and handling costs
  • Reduced maintenance

DryTec System Capabilities

The DryTec disinfection system offers several advantages for cooling tower water treatment over other chemical alternatives. It delivers 65% available chlorine compared to 12.5% available chlorine in bleach, translating to a lower cost per pound of disinfectant.

Everything begins with the innovative feeder. The feed system is designed to minimize maintenance and can provide extended capacities of up to 150 pounds of briquettes. Removable panels provide for ease of service. And an innovative hopper attachment allows for added chemical capacity and reduction in dust during chemical loading.

The system’s unique, EPA-registered dry briquettes are made in the USA and are formulated with a scale inhibitor to help prevent scale formation inside the chlorination chamber, ensuring reliable performance of the system. The briquettes have a longer shelf life than liquid bleach. Plus, the calcium hypochlorite is highly concentrated, which minimizes shipping costs compared to sodium hypochlorite. Calcium hypochlorite has a solid product form and solutions are made on-demand.
