Since 1958, Lytron has delivered thermal solutions to hundreds of companies including Airbus, BAE Systems, Boeing, Curtiss-Wright, Eaton Aerospace, Fairchild Controls, General Dynamics Land Systems, Harris, Honeywell, Lockheed Martin, Northrop Grumman, Pratt & Whitney, Raytheon, Textron, and many others. These prime contractors have turned to Lytron for expert design, analysis, verification, prototype development, and production of their liquid and air cooling components. Lytron’s products are used in a vast array of applications where size, weight, thermal performance, and structural integrity are critical factors in meeting demanding performance requirements.

Engineering Expertise

Developing innovative thermal solutions for today’s most challenging applications requires engineering expertise and experience. We continually invest in our engineering resources and capabilities. Lytron has extensive experience in heat transfer, fluid dynamics, materials and structural analysis. We utilize state-of-the-art simulation software to perform advanced thermal analysis (based on empirical data) and other tools, such as CFD and structural analysis software, to design an effective, custom solution. In addition, we make our own fin, enabling us to easily vary fin designs and densities to optimize performance. Our engineers work closely with our customers to support their design effort, from proposal, development, qualification, and LRIP, to volume production.

Our engineering lab includes a 21,000 ft3/min (595 m3/min) wind tunnel with a highly accurate computerized monitoring system for characterizing thermal performance. The monitoring system includes fluid flow stations and a multi-channel data acquisition system for recording verification data. In addition, we can perform proof and burst pressure testing, pressure-impulse testing, and thermal cycling, and offer full environmental testing including shock and vibration, salt fog, fire resistance, and more.

Program Management

Lytron employs a disciplined and proven approach to executing all phases of the contract. Our integrated project team partners with you to ensure program objectives are met. This team provides the necessary leadership, oversight, resources, and controls required to manage a successful project as well as effectively communicate the project status to both external and internal customers.

World-Class Facilities

At our 115,000 ft2 (10,684 m2) manufacturing facility, we use lean manufacturing principles, vertical integration, and a cellular organization to produce cost effective and high quality products. All of the critical operations are done in-house, including fin-forming, machining, vacuum brazing, heat treating, and welding, ensuring consistent and repeatable manufacturing. Engineering, design, production, and quality control departments are all housed in the same facility. This vertical integration gives us total control over the finished product, so you can be sure that all products are built exactly as the engineers intended.

Our computerized vacuum brazing work center consistently produces high quality brazed cold plates, chassis, and heat exchangers. To reduce impurities that inhibit the brazing process, aluminum components are cleaned, assembled, and brazed in an environmentally-controlled room. Additionally, we employ robust fixturing to ensure proper metal joining and product integrity. Lytron can vacuum braze parts up to 10 feet (3.05 m) long and 3 feet 2 inches (0.97 m) wide.

Quality

Lytron’s highest priority is producing cooling components of the utmost quality. ISO9001:2008 and AS9100:2009 registered, Lytron fully documents all processes. Ongoing training and regular quality audits reinforce our product quality initiatives. Our quality certifications and processes include:

  • ISO-9001:2008 and AS9100:2009 
  • Inspection system meets MIL-I-45208
  • Welding and brazing personnel certified to NAVSEA S9074-AQ-GIB-010/248, AWSD17.1, and SAE AMS-1595
  • Brazing process compliant to ANSI/AWS C3.4 and ANSI/AWS C3.7

Customer Service

Our focus on meeting customers’ performance, schedule, cost, and responsiveness expectations are evident in every decision and customer interaction. We service our customers globally utilizing a combination of direct sales support and manufacturer’s representatives. Our sales team is committed to providing exemplary service.

High Performance Cooling Solutions

Aluminum Vacuum-Brazed Heat Exchangers

Lytron offers two types of aluminum vacuum-brazed heat exchangers: plate-fin and flat tube. When thermal performance must be maximized and weight and size must be minimized, our plate-fin heat exchanger technology is the ideal solution. Plate-fin heat exchangers are compatible with most combinations of gas, liquid, and two-phase fluids. The heat exchanger core is a fluxless, vacuum-brazed unit built for cleanliness and leak free performance. Our unique flat tube heat exchanger construction uses multiple extended-surface channels inside each cooling tube to increase the surface area in contact with the fluid. The flat tube technology can be used for oil coolers, evaporators, and condensers. We can finish heat exchangers with coatings, platings, or Mil-Spec paints for harsh environments. For ultra-clean applications, heat exchangers can also be custom cleaned.

Aluminum Vacuum-Brazed Cold Plates and Liquid-Cooled Chassis

In a world of compact system designs with increasing power densities, cold plates are the preferred cooling technology for high-power contact cooling applications. Aluminum vacuum brazing is an extremely flexible cold plate and liquid-cooled chassis manufacturing technology, allowing for custom dimensions and custom fluid paths. Lytron’s aluminum vacuum-brazed cold plates and liquid-cooled chassis technologies are all custom engineered to meet the requirements of your application. More than forty years of cold plate manufacturing experience has demonstrated that our vacuum-brazed cold plates are consistently leak-free and reliable under the toughest conditions.

Tube-Fin Heat Exchangers

Lytron offers a broad array of tube-fin heat exchanger technologies to meet the needs of many applications. Our inner fin design boosts capacity by increasing the liquid-side heat transfer surface. To improve the air-side capacity, we can also vary the fin density and the tube spacing. As with all of Lytron’s tube-fin designs, unit size is flexible and fitting configurations are manufactured to your specifications. Lytron’s tube-fin heat exchangers are available in copper, stainless steel, aluminum, Hastelloy®, nickel, or cupronickel.

 High-Performance Air-Cooled Cold Plate
Value-Added Assemblies

Lytron designs and manufactures custom assemblies providing customers with an innovative design that meets system interface challenges. Assemblies include both cold plate and heat exchanger assemblies with fans, fan plates, mounting brackets, temperature/pressure sensors, relays, valves and other value added components so that the assembly arrives ready to be installed in your system.
