TWT Deposit Controllers (The Smart Controllers) are specifically designed to control scale deposits, bacteria, corrosion, algae, and colloids in boilers and industrial heating applications.

TWT Boiler/Heavy Industry System components include:

  • TWT Deposit Control System

  • Stainless Steel Reaction Chamber with Wire Mesh Flow Through Filter

The electronic deposit controller provides continual scale control in the treated system, resulting in reduced maintenance and more efficient operation (often yielding reduced energy and water consumption).  

What is the difference between fire tube and water tube boilers?

There are two basic types of boilers, fire tube and water tube.  Fire tube boilers are those commonly used in schools, hospitals, apartment buildings and commercial buildings. As the phrase implies, there is a fire "in" the tube and water is on the outside of the tube in a jacket that surrounds the tube bundle.  TWT offers both standalone components and fully integrated standard systems to address these needs.

Water tube boilers are mainly used for steam generation to develop electricity for distribution. This type of boiler is about five stories high and water is "in" the tube. These boilers are far more complex and have many sections to the system. TWT products have been used for numerous applications with success.  Since the volume of water to be treated in these systems is great, TWT recommends that you contact your TWT representative to help design a custom system for your site.

How does a boiler work?

A fuel or energy source at one end is drawn through (in) the tube, heating up the tube and transferring its energy to the water surrounding the tube. The energy or fuel medium may vary, but the concept is the same - take this energy and pump it to equipment that is designed to use the generated heat, e.g., heat exchangers, radiators, convectors, coils, eductors, etc.

How do TWT Deposit Control Systems help this process?

Thermal dynamics are greatly inhibited when insulating deposits accumulate on the walls of the tube next to the heat source (fire tube). This scale becomes a very costly problem, as widely acknowledged by industry experts, government research officials, and industrial managers worldwide . For every 1-1/32th inch of scale, the process unit will experience a 10% loss of efficiency (see the Federal Technology Alert - Energy, referenced above. The TWT Boiler and Heavy Industry Deposit Control System has the unique ability to clean and maintain an boiler system, while keeping the particulates in the water in suspension. Most of these solids accumulate in the belly of the boiler where they are "blown" down periodically to eliminate them from the water chemistry. The associated equipment is vulnerable to thermal dynamics loss. The TWT Boiler and Heavy Industry Deposit Control System will keep this associated blowdown equipment in top operating condition as well.

Engineers design a scale loading factor when considering the needs of heat exchange by a factor of up to 25% loss.  When equipment performance falls off in production rate, it is an indication that it is time to clean out the scale and deposits that have built up.  Chemical treatment has been a traditional means of maintenance for this condition, but such treatment requires down time for the system, as well as exposure to chemicals and handling safety issues.  This means of maintenance carries a high cost in terms of recurring chemicals purchases, proper storage and disposal measures,  OSHA compliance, environmental and health repercussions, and also leads to unnecessary wear on equipment and shortened equipment lifecycle. Chemicals can erode nearly any surface, at various rates, depending on base materials and temperatures.

TWT Deposit Control Systems offer advanced, safe, non-chemical technology to minimize or eliminate such risks, while providing substantial hard and soft dollar savings, and an environmentally responsible treatment alternative with comparable or better results.  Among the many advantages and  benefits:

  • Simple installation, significant maintenance reductions
  • Low capital investment and initial costs, no recurring costs
  • Improved efficiency and reduced operating costs (energy, water, and sewer charge savings)
  • High levels of production capacity for performance gains
  • Extended life of capital equipment (equipment lifecycle savings)
  • Elimination of chemical costs and exposure (other than oxygen scavengers)
  • Lower total KW usage due to less friction / stricture (now under mandate in some localities)
  • Man/hour maintenance to production ratio lessened (labor savings)
  • Environmental impact significantly reduced or eliminated
  • TWT equipment easily deinstalled and relocated, when desired
  • Seals, gaskets, shafts, impellers, volutes, metering valves, sensors, monitoring equipment, orifices, capillaries, etc., will experience lower maintenance, longer life, and better operating control.

It is important to note:

We have one exception to the non-chemical concept of TWT Deposit Control treatment.  Oxygen scavenger use in boilers is very important, and should be continued, even when treating the boiler with a TWT Deposit Control System. This additive absorbs the oxygen that might produce iron oxide or ferric acid. Such a condition could "eat" the base material, causing failure. We cannot eliminate this ingredient in the total boiler treatment. The use of strainers, filters, screens must be carefully designed so as not to produce a constriction or starving condition.

How does TWT Deposit Control technology affect fuel consumption?

The use of Triangular Wave Technologies products maintains the heat transfer ability is at peak operating conditions at all times, enabling the boiler to perform to its highest level of original design. The result is the optimum amount of energy input for the greatest return in production of heat transfer.

How does the TWT Deposit Control System affect the environment?

  • Since TWT Deposit Control is a non-chemical treatment, there is no impact on sewer or aquifer.
  • Since the process equipment will be operating at high efficiency, there will be reduced emissions of Sox and Nox, and the electro-static precips will require less maintenance.
  • Since TWT Deposit Control Systems are chemical- free, there will be far less storage and handling of hazardous materials, and less paperwork required.

TWT fluid management solutions make sense from operational, economic and safety points of view.
