They are formulated to out-foam, out-brighten and out-clean the HF-based products. Both are rated at 20 microns, and provide long service life. Most of the condenser coils we tested in the lab were cleaner than both of those. aerosol - 4290-75. Pro-Green cleans deposits on coils and rids condensate pans of slime.

A built-in pH color indicator shows how much to use, when to add more and helps tell when the system is clean. When the returning solution does not contain any bubbles or foam and is the same color as the solution in the tank, it is a sign the equipment is clean. A staggering price to pay for dirty coils. If the amount of water in system is not known, the starting dosage can be estimated from the following chart. Double action of high pressure blast and solvent cleaning restores design efficiency of condenser coils...quickly and easily. The one that you select will depend on several different factors. Prior to any cleaning, retrofitting, or replacing of your ducts, the cause or causes must be corrected or else the problem will likely recur. Once the drip tray is cleaned, use water to rinse off the coils. When properly sized, Micro-Plus will last for six months. When they can't actually see the scale, on the condenser surfaces, inside the piping and water regulated valves, there's a strong possibility it's there if the head pressure is high (more than 10 pounds above normal), or if the liquid refrigerant line is extra warm. Model #195200. In fact, excessively high head pressure is a common cause of motor burnout which costs considerable inconvenience and money. Protect equipment and maintain efficiency by using CalClean to remove dirt and greasy film from coils and filters.20 oz.

Liquid acids (such as Nu-Calgon Liquid Scale Dissolver) are somewhat more economical, and strong solutions will dissolve scale and iron oxide deposits faster than powdered acid solution. The life of the equipment itself is reduced. 2. Scale Control:The NP246R Micromet Cartridge contains sufficient 6R Micromet to provide scale control on ice machines making up to 900 lbs. Drain and flush out the sump. Cleaning: Through the use of Evap Pow'r or Tri Pow'r, evaporator coils condensate pans and surrounding surfaces are cleaned to remove existing soils and dirt build-up Disinfecting: Through the use of Bio-Fresh cd, the coil, pan and surrounding surfaces are disinfected. This restores designed heat transfer and air flow. Refill it with fresh water and start the pump again. This will cut down on the amount of scale remover you'll need, and prevent waste. And because R-22 has marginal miscibility with mineral oil, use of the "no oil change" approach will jeopardize system performance, particularly in low temperature application. And, when more accelerated foaming and brightening are desired, particularly where hydrofluoric acid-based products were used, select Nu-Brite or Foam-Brite.
