25 years supplying engineers and procurement teams across North America and globally. We spec, configure, and deliver the right heat exchanger for your application.
We spec and configure heat exchangers to your exact requirements — pressure, flow rate, fluid compatibility, footprint.
Deep application knowledge across HVAC, industrial, electronics, and data center cooling.
Domestic inventory means shorter lead times. From startups to enterprise procurement teams, we move when your project moves.
We supply a comprehensive range of heat exchangers and thermal products — every unit specced and configured to your application. Any size, any configuration.
Compact, high-pressure capable, configurable to any size. Copper or nickel-brazed. Our most versatile product — HVAC, heat pumps, data center liquid cooling loops, oil cooling, and more.
Designed for access, maintenance, and adaptability. Plates can be added or removed as process demands evolve. Ideal for large-scale industrial and HVAC applications.
Built for the most demanding environments — high temperatures, high pressures, aggressive fluids. Long service life. The industry standard for heavy process and power applications.
Super-high-pressure brazed plate heat exchangers for CO2 refrigerant systems and next-generation heat pump applications. Rated for working pressures up to 140 bar.
Direct OEM supply of Coolant Distribution Units and in-row cooling systems. Purpose-built for high-density compute, AI infrastructure, and hyperscale deployments. Configured to any rack density.
Specialized evaporator and condenser units for commercial and industrial refrigerant systems, heat pump cycles, and cold storage. Available in standard and corrosion-resistant configurations.
Compact brazed plate units combining precooler, evaporator, and separator in one assembly. High thermal efficiency with minimal footprint for compressed air dryer systems.
Brazed plate oil cooler series engineered for hydraulic oil, transmission fluid, and compressor cooling in industrial power units. Compact design, high thermal efficiency.
Double wall, asymmetric, nickel/stainless, high-temperature, corrosion-resistant, and impact-resistant series. If you have a spec, we can source and configure it.

SDG International was founded in Los Angeles with one purpose: get engineers and procurement teams the right heat exchanger, faster than they can find it themselves.
Over 25+ years we've built deep product knowledge, long-standing manufacturer relationships, and a reputation built on getting it right the first time. We listen to the application, then find what fits.
We supply companies of all sizes — from startups to enterprise procurement teams — across industrial manufacturing, HVAC, electronics, and data center cooling.
We work directly with leading heat exchanger manufacturers to bring you a comprehensive product lineup. Our relationships are built on quality, consistency, and the ability to source the right product for any application.
Our lineup covers brazed plate, plate & frame, shell & tube, fluid heaters, evaporators, CDUs, and more — all sourced from manufacturers whose engineering standards match what our clients demand.
Choose the form that fits your inquiry — or just send us a message.
Use the Thermal Application form to give us the detail we need to provide an accurate recommendation — temperatures, flow rates, fluids, and operating conditions.
Pricing, lead times, distributor questions, or anything else — use the General form and we'll route it to the right person.
We'll review your parameters and get back to you with a qualified recommendation.
