Key Benefits

By integrating an AirBTU VPRR heat transfer solution, industry professionals can avoid common pitfalls and “design in” reliability and efficiency. The Air BTU VPRR is designed to:

Avoid cold-end corrosion. The introduction of low-temperature air can result in cold spots within a recuperator, causing condensation of some constituents of the process gas stream. The resulting reaction between this corrosive condensate and the heat exchanger surface is commonly referred to as cold-end corrosion. This destructive mechanism is “designed out” of the AirBTU VPRR, making it the ideal Heat Exchanger for Sulfuric Acid Applications.
Eliminate stress failures. Temperature gradients across the tube bundle can lead to uneven stress concentrations at the tube-to-tube-sheet connections. These result in tubesheet failures with subsequent losses in production and costly repairs. We design in uniformity to eliminate this failure mode.
Reduce pressure drops. Our VPRR features a proprietary design that reduces pressure drops for the best energy efficiency.
Maximize thermal efficiency. Flow dynamics modeling is used to evaluate tube layouts and pass arrangements to create a symmetric design with optimal film coefficients and overall heat transfer rate. The resulting design requires less surface area and minimizes material and fabrication costs.
Minimize maintenance downtime. In addition to minimizing failures caused by cold end corrosion and uneven mechanical stresses, we can “design-out” the potential for fouling.
