Attacks & dissolves rust, lime, scale, corrosion & mineral deposits on metal and concrete. Ideal for heavy-duty descaling of water lines, AC units & boilers.

A pleasantly scented foaming, no rinse coil cleaner. Powerful spray reaches further into coils and fins. Cleans in 1 to 2 days without requiring a separate rinse step.

Controls scale, sludge & buildup in small condensate and drip pans to help prevent clogs and overflow. Ideal for HVAC systems up to 3 tons; use 1–2 pills monthly.

These gel tabs are formulated to provide six months of protection for A/C condensate drains and pans. The tabs lock into place and the slow-release action guarantees to continuously clean and prevent musty odors from developing in pans.

Utilizes a high foaming formulation for cleaning chiller and evaporator coils of efficiency robbing particles. Because United 266 “rinses automatically” with the natural condensation action on these coils, it can be used to clean coils in place with no messy rinse.

Cleans and brightens chiller & evaporator coils to improve system efficiency. Oxygen-powered, bleach-free formula penetrates to lift dirt and stains without harsh acids.

Formulated to control corrosion and scale deposition in closed loop heating and cooling systems, UNITED 308 is Earth Smart® certified. It is formulated to be safer in use for both the user and the environment. When used as part of a complete United Laboratories’ Cycle Smart cooling tower treatment program, it minimizes environmental impact.

A microbiocide for cooling towers and air washers.

A phosphate-based boiler treatment designed to protect steam boilers from corrosion and scale formation.

A steam and return line treatment designed to pass out of boiler with steam to protect all components of the steam and return system against rust, corrosion and pitting.

A synthetic polymer liquid steam boiler treatment product offering a one-drum, low maintenance program that protects against scale, corrosion, and oxygen pitting.

UNITED 313 is a blend of organic penetrants and dispersal agents for use in cooling water systems. It functions by penetrating the matrix of organic deposits, which results in the sloughing off and dispersal of the organic matter. This product is Earth Smart® certified; formulated to be safer in use for both the user and the environment. When used as part of a complete United Laboratories’ Cycle Smart cooling tower treatment program, it minimizes environmental impact and keeps your cooling system operating cleanly and efficiently.
