  • Eliminate lime scale formation

More than a filter, more than a feeder, Micro Plus is the complete treatment program for commercial ice makers, coffee urns and brewers, beverage machines and other water-using equipment such as humidifiers, steamers and residential refrigerator ice makers.

Micro-Plus Treatment Systems are available in a variety of size capacities, from the Micro-Plus 2, which can be used on equipment using up to 12.5 gallons of water per day, to the Micro-Plus 16 for treating up to 100 gallons of water per day. Micro-Plus systems are designed and manufactured to eliminate or control the three primary water-related problems: lime scale, silt and sediment, and objectionable tastes and odors encountered in ice makers, coffee urns and other equipment. These problems all reduce the designed capacities of this equipment, and they cause operation and service costs to increase.
