Condensate Polisher Systems for Boilers
Condensate polishing systems remove impurities such as calcium, magnesium, iron and copper, which results in improved boiler feed water quality reducing energy consumption, water consumption, and costs.

Condensate polisher systems are the ideal solution for cleaning boiler condensate return water. Our stainless steel condensate polishers are often used in power generation, co-generation plants, and heavy industries with large boiler systems.
Do you need extra safety and redundancy in condensate polishing? Nancrede Engineering’s patent-pending Zero Hardness™ failsafe industrial water softeners are highly efficient and greatly reduce chances of failure and salt waste, reducing risk and improving your bottom line. Learn how the Zero Hardness™ failsafe industrial water softener provides a higher level of water quality for boiler feeds and other critical applications.
Condensate polishers result in lower operating costs by providing cleaner water that protects and lengthens the useful life of equipment such as boilers. Standard capacity for Nancrede condensate polishers ranges from 150,000 grains to 5,400,000 grains per tank with continuous flow rates from 0 to 1,200 GPM (gallons per minute). Nancrede Engineering offers specially engineered condensate polishers systems that can be designed to meet the exacting needs of your process.
Our condensate polishers are also available with anion resin to remove negatively charged ions. These condensate polishing systems use a mixed bed design with both cation and anion resins. These condensate polishers systems are called deep bed systems and use strong acid and strong base bead resins to produce a very high quality demineralized water.

Condensate Polisher Process Theory – Cation Only
Our industrial condensate polishers use hydraulic or pneumatic valves, which feature a co-current regeneration sequence. Initially, strong acid cation resin in the sodium (Na +1) form is placed into service. During the sodium cation exchange water softening process, sodium ions are exchanged for undesirable quantities of calcium (Ca +2), magnesium (Mg +2), and iron (Fe +2). Sodium ions already present in the water being softened pass through the process unchanged. Upon exhaustion of the resin (as indicated by unacceptable hardness leakage), a regeneration sequence involving sodium chloride (NaCl) is utilized. Although the water is softened, the total dissolved solids content remains unchanged.
