This illustration demonstrates how Xchanger heat exchangers are used in a variety of applications. 

The red items are Xchanger heat exchangers. Mouse over them for more information and a link to each product.

High volume, low pressure flows, such as those produced by rotary lobe (Roots type) blowers and multi-stage centrifugal require unrestrictive, free-flowing heat exchangers.   Low pressure air heat transfer is an Xchanger specialty.  In most applications, the pressure drop through our exchangers is under 5 inches of water column (or 1/4 PSI).

Xchanger heat exchangers can be designed to cool, heat or dehumidify air streams.  Service fluids including steam, refrigerant, oils, water, liquid nitrogen and ambient air are used to accomplish a wide variety of heat transfer goals.

All Xchanger heat exchangers are designed using extended (fin) surface.  Finned heat exchangers are very advantageous with air or other gases - they're nearly as effective as bare tubes and a fraction of the cost.  This type of surface is very effective in liquid-air or air-air heat transfer applications, but it is not suitable for liquid-liquid service.

Common uses of Xchanger heat exchangers include:
• Cooling pneumatic conveying air to prevent the conveyed product from temperature related degradation such as melting.
• Heating pneumatic conveying air to prevent condensation or line plugging.
• Dehumidifying conveying air to prevent moisture gain in hygroscopic products.
• Precooling / Intercooling vacuum pumps to protect the pumps from high temperatures.
• Cooling air/vapor streams headed for activated carbon beds used in soil remediation.
• Heating air to regenerate desiccant in air dryers.
• Cooling compressed air or liquids with ambient air.
• Process air heating, cooling or dehumidifying.
• Condensing solvent vapors at storage tank and reactor vents.
