No. 85 Algaecide, is a polymeric, cationic biocide that has been developed for controlling the growth of algae, bacteria, and fungi in recirculating water systems such as cooling towers, evaporative condensers, closed cooling water systems and industrial air-washing systems. Algae are microscopic plants that grow rapidly in cooling towers, spray ponds and other recirculating systems exposed to sunlight. These free-floating growths can be carried to the condenser or heat exchanger by the condenser or heat exchanger by the recirculating water where they lodge and act as binders for sludge and suspended matter. In addition, algae can contribute to the formation of slime deposits by providing organic matter necessary for the growth of bacteria. These biological growths restrict water flow, reduce heat transfer efficiency and increase head pressures, all of which result in lower efficiency and increased power and service costs. Treatment of recirculation water with No. 85 Algaecide prevents growths of algae and bacteria from developing to the point where they cause the problems described.

• Controls the growth of algae, bacteria, and fungi in recirculating water systems
• Can be slug fed, drip fed or fed with a chemical solution pump
• Effective in both alkaline and acid waters
• Does not cause foam like most algaecides
• Non-volatile

Nu-Calgon Nu-Blast 4290-75 Condenser Coil Cleaner, 18 oz Aerosol Can, A"no rinse required" condenser coil cleaner in a convenient aerosol package. Double action of high pressure blast and solvent cleaning restores design efficiency of condenser coils quickly and easily. It is non-flammable and non-conductive with no rinse required, as the cleaning solvent evaporates completely. This high performance aerosol product offers maximum cleaning of condenser coils. The high solvency formula and blasting nozzle powerfully separates the undesirable materials from the surface. Only use with adequate ventilation.Sid Harvey Item #:4290-75: Replaces Part #:'s : 4768,

Foam-Brite's foaming power is incredible. It is a non-acidic, alkaline-based cleaner and brightener containing the best available biodegradable ingredients and a unique chelant/surfactant package to quickly penetrate and remove greasy soils and oxidation. Its high foaming formula helps lift greasy soils out of the coil, leaving finned coils clean and bright. It can be used to replace the more dangerous HF acid-based products for condenser coil cleaning because Foam-Brite does not contain any acids.Sid Harvey Item #:4178-08: Replaces Part #:'s : 4744,

Eco-Lyme is a new odorless chemistry for the HVAC/R market that provides a unique blend of performance and safety to the environment and user. The product is specially formulated to achieve descaling behaviour of competing hydrochloric acid based descalers. However, the active ingredient is substantially safer on equipment metals. Eco-Lyme is ideal for stainless steel construction - eliminates the issue of localized corrosion/pitting caused by repeated use of hydrochloric acid. Eco-Lyme is readily biodegradable per OECD 301A, a recognized international method for determining biodegradability for applicable chemistry. Eco-Lyme uniquely provides top-tier performance with a validated eco-profile when a 'green' descaler is sought.

• Powerful environmentally friendly descaler
• New chemistry rapidly removes scale and rust - similar in performance to hydrochloric acid (also described as hydrogen chloride)
• Significantly safer on metals than competing hydrochloric acid based descalers
• Safe on carbon steel, aluminum, stainless steel and copper
• Readily biodegradable
• Odorless - making it safer to handle
• Low foaming chemistry for added safety
