ConDex Energy Heat Recovery System

The ConDex Energy Recovery System, the breakthrough technology frpm Combustion and Energy Systems that perfects the recovery of heat from exhaust gases. Flue gases from boilers, turbines, ovens, dryers, etc. - single or multiple sources of waste heat, the ConDex System recovers tremendous amounts of waste energy and returns it directly to your operation. In fact, the ConDex Condensing Heat Recovery System is so effective that the payback period can be as short as six months - and the savings are guaranteed.

What is the difference? The ConDex System utilized specialized metallurgy, and proprietary design engineering to significantly enhance the heat transfer process in a wide variety of applications. The ConDex System is also dramatically smaller and far more efficient than competing designs. As a result, the ConDex System costs far less to operate and maintain. Yet is has no impact on the exhaust source and operates in conjunction with your existing operation. Better still, in addition to the significant financial benefit, the ConDex System also reduces associated harmful emissions such as NOx, SOx, and CO2 greenhouse gasses from your operation.

Boilers (150 HP - 500,000 PPH +), turbines, ovens dryers, engines, etc., for most any waste heat exhaust requiring recovery, there is a ConDex Energy Recovery Solution!

Better performance.   Better savings.   Better environment.
That's a ConDex System.

By heating cold process liquids with hot exhaust gases, the ConDex system recovers both sensible and latent heat energy.

When incoming cold fluid enters the ConDex exchanger and the hot exhaust gases pass through the proprietary ConDex exhanger unit, so much energy is exchanged that the gases are cooled beyond the point where the water vapor condenses out of the exhaust gas, releasing and recovering the heat it took to vaporize the water initially.

This phase change from vapor to liquid recovers 980 Btu's of energy for very pound of water condensed.

ConDex is not only more effective than competing systems, it also costs less to operate and maintain. By recovering such significant amounts of heat from an exhaust gas that it is cooled below its dew point, a dramatic increase in fuel savings is achieved.

     ConDex maximizes water condensation and the      resulting recovery of latent heat. This key advantage is      achieved in two ways: special metallurgy with high heat      transfer capabilities and the addition of fins to dramatically      increase the heat transfer surface area.

The ConDex System offers many competitive advantages over direct contact "spray tower / scrubber" types of condensing heat recovery systems, such as:

The ConDex Systems can produce much higher recovered temperature returns on heated fluids, thus recovering much more energy. Because the temperature rise of the liquid being heated in the ConDex system is not limited by the dew point of the exhaust gas, the ConDex System is much more effective than competing designs. Typically, a gas-fired boiler will have an exhaust gas dew point of 135°F, thus limiting the recovery temperature for heated water from a direct contact style system to 130 - 145°F. Compare this to the ConDex system's ability to heat the same volume of water to 200°F +, and it is easily seen how the ConDex System can recover much more energy.

Unlike the direct contact spray tower systems, the ConDex unit does not contaminate the process water with the products of combustion. In the ConDex system only the condensed water on the outside of the tubes (typically 2 - 20 GPM of water) absorbs contaminants through contact with the flue gas. This eliminates the requirement for the use of secondary plate & frame heat exchangers, thereby eliminating the loss in heat and efficiency associated with the direct contact style systems. The costly chemical treatment systems associated with direct contact spray towers are also not required with the ConDex System either - another big savings!

Due to the unique ability of the ConDex System to provide everything from low-grade to high-grade heat, it can also provide tremendous savings by using recovered energy from flue gases for absorption chillers in refrigeration or air conditioning applications!
