Hard Water Problems For Boilers

  • Mineral scaling costs industry millions each year in downtime, lost production, early replacement of capital equipment and increased energy bills.
  • Water is used extensively throughout a variety of industries. However, as it evaporates, it leaves solids and mineral deposits in unbalanced proportions. These deposits create sludge and fouling problems. In addition to these concerns, the oxygen in water is a chief factor in the cause of rust.
  • Limescale build-up, in pipework, boilers and heat exchangers, is a common problem for business and industry. There has historically been only one way of addressing the problem – chemical water softening.
  • If the water supply to boilers is not conditioned, scale build-up increases fuel consumption and the boiler deteriorate rapidly through the external overheating of the plates and tubes.
  • Whenever water is heated or steam is generated, the minerals and chemicals contained in the water supply, cause operational problems by depositing as scale or by forming incondensable gases.
  • Even in pure water or condensate, chemical interactions occur between the boiler walls and the surface of the water, as it changes into steam causing oxygen attack in the boiling vessel.

Chemical Softening Disadvantages

  • If water is softened (ie treated chemically) sodium carbonate hydrolyses to produce free alkali that is aggressive to boilerplates and tubes.
  • The problems with Chemical Softening Method have been numerous and include corrosion and the cost of adding salt to the softening reservoir and the resulting effluent having higher concentrations of sodium.
  • Another problem has been that softening does not remove existing calcium carbonate build-up or completely stop calcium carbonate build-up. This has to be removed by acid or scraping – a further cost in terms of material, operator time and generator down time.


  • UB’CAL Electronic Water Conditioning Systems are specifically designed to provide today’s industrial companies with an effective and environmentally friendly alternative to chemical use
  • UB’CAL Electronic Water Conditioner can treat any size of pipe, regardless of material or flow rate. UB’CAL can design and manufacture custom-built units for a wide range of specialist applications
  • UB’CAL provides you with an eco-friendly water treatment system which protects your water pipes, boiler and equipment against scale and rust.
  • UB’CAL treats your water without applying any chemicals or salt. The result has been savings in chemicals, time and lost production associated with cleaning of the system
  • UBCAL removes rust easily and replaced by a very thin black protective layer, called Magnetite

Water Savings

  • In the civilized world Industry has to pay for its disposal of water. As most of this equipment uses automatic blow down based on the electrical conductivity of water, it is easily seen why water can be saved.
  • The longer it takes before a certain conductivity level is reached the fewer blow downs. Adding chemicals to water will Increase the conductivity. Savings of at least 50 % in water usage is possible.
  • The total savings on water usage, cost of water disposal and cost of chemicals gives an extremely quick return on a one time.

How It Works?

  • The UB’CAL – Hard water treatment system alters the structure of the hard water minerals making the “conditioned” water act like naturally soft rain water with its ability to dissolve existing scale back into the water.
  • The UB’CAL’s resonance frequencies progressively break down and remove any existing scale deposits and allow the boiler to regain its original thermal efficiency.
  • High resonance Frequencies are applied by passing UB’CAL’s signal through a coil wrapped around the pipe to be treated. The signal consists of a frequency modulated (FM) wave form within the audio frequency (AF) width this inaudible sonic frequency signal sets up a dynamic field around and through the coil, pipe and water, and neutralizes all the minerals present in the water within seconds.
  • The UB’CAL uses a series of controlled complex modulating high frequency waveform that neutralises the bonding ability of minerals that are contained in our water.
  • This results the breakdown of large mineral crystals into tiny non-reactive particles (less than 4 microns in size) & then prevent them from reacting with other minerals or bonding to any surface to from scales
  • The process is so effective that existing scales are progressively broken down & flushed away in due course of time. The conditioned gaseous ions results in non-corrosive & better tasting water.
