Heat Exchangers Custom Heat Exchanger Technologies Performance Comparison Chart Plate-Fin Oil Coolers Tube-Fin Performance (Q/ITD) This chart compares the performance of different heat exchanger technologies, including plate-fin heat exchangers, flat tube oil coolers, and tube-fin heat exchangers. Performance is shown as Q/ITD, the heat load divided by the difference in incoming temperature of the liquid and air. Units are not shown so that heat exchanger technologies can be compared regardless of size. Please visit www.Lytron.com to see additional custom heat exchangers. Water Flow Custom...

Custom Heat Exchangers Vacuum-Brazed Heat Exchangers Lytron’s aluminum heat exchangers offer superior heat transfer. They are vacuumbrazed in an environmentally controlled room for maximum cleanliness, quality, and reliability. With our numerically controlled vacuum brazing process and robust fixture designs, we can ensure complete metallurgical bonding between the fins and the separator plates or flat tubes. This guarantees ruggedness and leak-free operation. Lytron operates several vacuum brazing ovens, including one that can braze parts up to 10 feet (3.05 m) long and 3 feet 2 inches...

Heat Exchangers Custom Flat Tube Heat Exchangers Lytron’s vacuum-brazed, extruded flat tube technology is used in oil coolers, condensers, and more. Flat tube technology allows for many customization possibilities. Four different flat tube widths are available, and the length and the number of tubes can be varied. The flat tube can also be bent into a 1/4˝ (6.35 mm) inside radius without buckling, so heat exchangers can be manufactured in a curved shape if needed. Custom fittings and manifolds can be added, and flat tube heat exchangers can be painted or anodized for extra protection....

Custom Heat Exchangers Value-Added Assemblies Custom Heat Exchangers Lytron also designs and manufactures custom heat exchanger assemblies, providing Original Equipment Manufacturers (OEMs) with an innovative design that meets system interface challenges. Heat exchanger assemblies include plate-fin heat exchangers, flat tube heat exchangers, evaporators, condensers, oil coolers, or tube-fin heat exchangers, as well as any number of other components that make integration of your heat exchanger faster and easier. The simplest heat exchanger assemblies are heat exchangers with fans, while the...

Copper Heat Exchangers 6000 & OEM Coils Copper tubes are compatible with water, EGW, and other common cooling fluids Supplied with built-in, fan-ready mounting hardware 0.028” (0.7 mm) wall tubing ensures fluid circuit durability Fluxless, silver-brazed joints provide leak-free operation and high reliability • Engineered for performance: The OEM Coils and 6000 Series are both engineered for performance. The seamless copper tubes are expanded into the fin with an extruded full collar that ensures excellent metal-to-metal contact to optimize thermal performance. However, with the 6000 Series,...

Aspen® & 4000 Series Stainless Steel Heat Exchangers Welded, argon-purged joints maximize internal cleanliness Available with straight, beaded, or 37° AN flare fittings. Aspen 316L stainless steel tubing compatible with deionized water and corrosive fluids 4000 Series Standard Heat Exchangers The Aspen and 4000 Series tube-fin heat exchangers are ideal for applications where deionized water or corrosive fluids are used and a high performing heat exchanger is required. When a slightly lower performance/size ratio is acceptable, the Aspen offers better value - 80% of the performance of the...

Aluminum Heat Exchangers: Oil Coolers ES Series Fluxless, vacuum-brazed core for strength and reliability Low pressure drop due to unique flat tube and header designs Welded headers, pressure tested to 150 psi (10.3 bars) Extended surface flat tube design provides 2.5 times better performance than competitive units Available with or without a fan plate GRAPHS Finish options: aluminum or black paint ES Series oil coolers are engineered for high performance with poor heat transfer fluids such as oils and EGW. They provide up to 2.5 times greater thermal performance per unit volume than...
