RECLEAN PRO™ Approach to Water and Energy Savings:

RECLEAN PRO’s™ Water/Energy Savings Approach – To provide a healthy, clean condenser/evaporative system is our primary goal A clean heat exchanger will save water and energy, as well as extend equipment lifecycles.

RECLEAN PRO Concentrates on Total Suspended Solids Removal and Control of Total Dissolved Solids Our technology improves thermal transfer in the condenser and evaporative heat exchangers. This will utilize each chiller to its optimal efficiency thereby saving energy. In turn, the cooling towers are a slave to the chiller heat load and abilities to transfer temperature through their exchangers. This is where water savings are achieved.

By removing suspended solids and controlling dissolved solids RECLEAN PRO has been successful in reducing large percentages of make-up water to the cooling towers and energy needed to operate chillers. Unlike most side-stream filters RECLEAN PRO’s™ system uses no media and requires no backwash or continuous maintenance.

RECLEAN PRO’s™ philosophy is to concentrate on evaporation rates rather than trying to extend bleed cycles. Make-up water to your cooling towers is divided into evaporation (75%) and bleed (25%). Bleed cycles are a necessary evil to rid the system of dissolved minerals (scale). Pushing or extending bleed cycles is risky business and will cost energy in the long run. Remember, bleed makes up only 25% of a towers usage in most cases.

RECLEAN PRO removes 95% of suspended solids down to one micron, which greatly increases the condenser water’s thermal transfer rate, and also manages dissolved solids that may produce fouling (scale). RECLEAN PRO monitors chillers approach temperatures which will verify our system’s effectiveness in keeping exchanger tubes clean. RECLEAN PRO monitors and logs monthly make-up and bleed usages.

RECLEAN PRO concentrates on evaporation rate needed – 75% of your system’s usage.
RECLEAN PRO’s™ water savings have never been the result of increased bleed cycles. Our success is in direct proportion to the improvement in equipment efficiencies.
RECLEAN PRO has been servicing Fortune 500 companies since 1997.

FOULING : Removal of Total Suspended Solids (TSS)
( Dirt I Pollen I Airborne Particles )

  • A 1000-ton tower will collect over 3000 pounds of solids in one year. 200-tons – over 600 pounds per year.
  • Particles over 20 microns cannot stay in solution and will settle out in tower basins and quiet areas throughout the condenser loop.
  • Particles from one to ten microns tend to stay in solution and foul the entire condenser loop. These particles make up the majority of suspended particle count in an open condenser loop (see Particle Analysis reports).
  • High particle counts decrease thermal transfer rates costing energy water and equipment life cycles. Side-stream filters have been used to remove these solids from open loops: standards- sand centrifugal separators- do not remove microns smaller than 10 and are high maintenance.
  • RECLEAN PRO utilizes a patent pending particle precipitator that is a side-stream installation. RECLEAN PRO uses no media to remove suspended particles and requires no backwash or maintenance of typical sand filters. Our technology utilizes a combination of low DC voltage and magnetic electrodes to coalesce and parcipitate suspended particles down to the sub-micron level.
  • RECLEAN PRO will remove 95% of all TSS down to one micron.
  • RECLEAN PRO’s™ treatment skid is a fast inexpensive installation. Our system is designed for a 15+ year
  • RECLEAN PRO’s™ treatment skid program for control of TSS will save 10-15% in efficiency levels of the
    chill/tower operation year-after-year.



FOULING : Removal of Total Dissolved Solids (TDS) (Scale)

  • As a cooling tower evaporates condenser water mineral salts are left behind (TDS). These minerals concentrate and are discharged from the open loop by means of a conductivity meter and bleed valve.
  • Make-up water is piped to the cooling towers to replace evaporation (75%) and bleed (25%) water loss.
  • These minerals form scale on heat transfer surfaces, decreasing thermo transfer and costing energy, water and equipment life-cycles.
  • Scale forms in the laminar boundary layers where water, heat and pipe surface meet.
  • Moving water and stationary pipe produce frictional laminar boundary layers – dead space between water and pipe. This is where scale and corrosion usually take place.
  • Laminar boundaries affect thermo transfer. Scale affects thermo transfer and the system’s ability to discharge heat.
  • When an electrostatic charge is introduced to a moving fluid, laminar boundaries collapse. Scale that formed in the dead space (laminar boundary) is now subjected to shear force and is removed.
  • When laminar boundary layers are decreased, thermo transfer increases and energy and water efficiencies are increased.
  • RECLEAN PRO’s™ patented high voltage electrode prevents scale from forming and, if present, removes it.
  • RECLEAN PRO’s™ treatment skid program for the control of TDS will save 10-15% in efficiency levels of the chiller/tower operation.




Electrohydrodynamic Heat Transfer:

The air conditioning and refrigeration industry has been increasing the efficiency of its equipment dramatically. One of the biggest contributors to these efficiency gains in the past has been the modification of heat exchangers to use  nhanced surfaces, such as attached/integral fins, porous coatings, reentrant cavities and internal grooving. Today, a radically new method of increasing heat transfer efficiency, called the electrohydrodynamic (EHD) technique, is being investigated. Some early results have shown more than a 1000 percent increase in heat transfer coefficients of R-134a.

What is EHD? How does it work?

The EHD technique works by applying a high-voltage electrostatic potential field across a heat transfer fluid, such as a refrigerant or refrigerant mixture. The applied electric field serves to destabilize the thermal boundary layer, increasing boiling or condensation of the fluid near the heat transfer surface, and producing better mixing of the bulk fluid flow. The net effect is to increase the heat transfer coefficient, sometimes by several hundred percent. Although the EHD technique can be applied to both single phase and phase change heat transfer, it is more effective when applied to phase change processes (boiling and condensation).

How is the electric field applied?

A common method for using the EHD effect is to suspend a charged electrode (for example, a straight wire running parallel to the tube) in the fluid medium and to electrically ground the heat transfer surface. The reverse case (charging the surface and grounding the wire) is also possible. The applied electric field can be either direct or alternating. The field polarity in most cases has little effect on the enhancement mechanism, particularly for the phase change processes. For shell-and-tube heat exchangers, the tube and shell sides can be simultaneously energized by placing electrodes in both the tube and shell sides. For plate heat exchangers there is no need for an external wire electrode, as the plates themselves can serve as the electrodes by charging one plate and grounding the other.

What are the benefits of EHD?

Initial studies have been done with several refrigerants, including R-123, R-134a, an R-11/ Ethanol mixture, and R-404A. The improvements in heat transfer are dramatic, especially at lower refrigerant qualities (more liquid and less vapor). This may allow manufacturers to produce highly compact heat exchangers with less complicated surfaces without sacrificing heat transfer efficiency.

Another potential application is to use continuously EHD enhancement with smaller, less costly heat exchangers. The EHD effect would offset the loss of heat transfer capacity experienced from the smaller heat exchanger. Similarly, EHD could be used in place of, or in conjunction with, enhanced surface heat exchangers.
