Nu-Calgon 4293-04

Nu-Calgon 4207-P2 Liquid ice machine cleaner is a 75% phosphoric acid of the highest food-grade quality. It is fast acting yet very safe to use and it does not give off any harsh fumes. Because of its 75% phosphoric acid content, it is the most concentrated ice machine cleaner in the market. It has a specific gravity of 1.63 and weighs 13.6 lb/Gallon. Usage rate is 8 fl-oz with threeGallons of water. The number one category of problems troubling an ice machine are water-related and the most frequently is lime scale. As the water is frozen into ice during an ice maker's cycle, the naturally occurring dissolved minerals in the water, some of which can combine to form lime scale, remain behind in the unfrozen recirculating ice water simply because water tries to freeze in its pure state. As the cycle continues and more water is made into ice, the minerals over concentrate and eventually precipitate as a lime scale deposit. As the scale begins to form, it creates a physical obstruction that results in: plugged distribution holes, restricted water flow and eventually the ice maker will hang-up or jam. Ice harvest is reduced and eventually the machine will shut down, requiring service. This sequence of events can affect both cubers and flakers. Some believe that flakers are free of scale problems since all of the water is made into ice. Not true. Flakers can scale-up as well, jamming the auger and eventually resulting in a broken belt or drive mechanism.

Nu-Calgon 4360-88 The best and the safest dry cleaner. Season start is a powdered sulfamic acid formulation that contains the best inhibitors available for protecting all metals including Gallonvanizing. A built-in pH color indicator shows how much to use, when to add more and helps tell when the system is clean. A wetting agent and an anti-foam agent are included to help it do a better cleaning job. Season start lowers head pressure, removes scale, and is safe on all system metals. It's easy-to-use. Use one container per 10 Ton of cooling capacity.

Nu-Calgon 4900-10 I-Wave Air Purifier 4,800 CFM
With technology installed in over 100,000 applications, iWave-R is the worlds first self-cleaning, no maintenance needlepoint bi-polar ionization generator designed specifically for treating air in residential duct A/C systems. As the air flows past the iWave-R, positive and negative ions actively purify the supply air, killing mold, bacteria and viruses in the coil and living space. The ionization process also reduces allergens, smoke and static electricity, as well as controlling odors (cooking, pet, VOCs) and other particles (no more sunbeams) in the air without creating ozone or any harmful byproducts. iWave-R treats the air in any brand of residential duct air conditioning systems up to 6 Tons (2400 CFM) in size with no maintenance and no replacement parts. Designed for universal mounting, the iWave-R typically requires only 15 minutes to install inside or outside of duct, or to attach magnetically near the indoor fan in the air handler. Simply connect to power using its patent-pending VAC age input capability. Install between air filter and cooling coil to treat the indoor coil; as an alternative, the iWave-R can be installed in the supply air. iWave-R always works at peak performance, producing over 160 million ions/cc, more than any other ionizer product on the market. Its patent-pending self-cleaning design includes a programmable cleaning cycle that can clean the emitter brushes every 1, 3, 5 or 10 days. The iWave-R is factory set to clean every third day which is adequate for a typical installation. iWave-R does not create black walls as negative-only ionizer products will do.

• Patent pending self-cleaning design ensures ongoing peak performance
• Needle point ionization actively treats air in the living space
• Easily installs in minutes in A/C system
• Universal mounting with magnets
• Flexible design with no replacement parts
• Kills mold bacteria and viruses
• Reduces allergens, odors, smoke, static electricity and other airborne particles
• Reduces ventilation requirements
• Keeps coil cleaner
• Programmable cleaning cycle
• Alarm contact option for secondary notification
