No. 340 Liquid Scale Inhibitor is an organic product based upon AMP phosphonate. It is formulated for preventing scale in cooling towers and evaporative condensers. It is extremely effective, particularly when the water is extremely hard and high in alkalinity. No. 340 is stable and there is no breakdown up to the boiling point, even in highly alkaline or acid solutions. In addition, it is freeze proofed to -10ºF and is most effective and economical at treatment levels of 12–15 parts per million (about 1 gallon per 100,000 gallons of water).

Cooling towers and evaporative condensers can be troubled with scale formation where the water is hard and high in alkalinity. This scale can form on condenser surfaces, piping, valves and tower fill. And when it does, water flow and heat transfer are reduced, head pressures go up, power is wasted and a costly motor burnout can result. Treatment with No. 340 can prevent these problems.
