Arch Chemicals, Inc., a Lonza company, produces the new generation Constant Chlor® Plus calcium hypochlorite briquette feed systems that provide increased capacity and accuracy that exceeds its first generation system, plus new capabilities and features that further enhance operation, maintenance and safety.

The model MC4-150 system retains all of the key features that made Constant Chlor® the system of choice for years, such as optimum solution consistency and a small footprint; but its loading and feed rate capacities are much higher, allowing for its effective service to larger treatment facilities. Maintaining constant residual levels is even easier with the second generation system. This model features an HMI with touch screen for easier functionality.

The feeder uses NSF Standard 60 listed Constant Chlor® Plus dry calcium hypochlorite briquettes and patented spray technology to produce fresh liquid chlorine solution as needed. The fresh made reservoir is filled with approximately 1.7% available chlorine solution and volume is maintained via an electronically controlled spray manifold. The hypochlorite solution is injected into the application with an appropriate, highly accurate positive displacement chemical metering pump specified for the application. Most metering pumps can be mounted directly to the pump mounting plate on the Constant Chlor® skid.

Other Features Include:

  • Large hopper provides a dry chemical capacity of 225 lbs.
  • Unit is pre-plumed and skid mounted for simple installation
  • All external parts make for easy PM.
  • Comes with secondary containment skid
  • Convenient AvCl solution sample feature.
  • Automatic solution tank refill
  • Separate fill cycle switch allows maintenance without service interruption.

With our new generation Constant Chlor® feed system, chlorination operations become even more effective and efficient. Most importantly, a steady, constant dose of hypochlorite disinfection solution is always there when you need it.
