Rear Door Heat Exchanger: Working Principle, Selection, Sizing, Cost, and Maintenance
A rear door heat exchanger (RDHx) removes heat from server exhaust air at the rear of a data center rack and transfers that heat to a liquid cooling loop. It is a practical option for increasing rack cooling capacity without replacing every server with direct-to-chip liquid cooling. The correct rear door heat exchanger must be […]
Heat Transfer Unit Working Principle: How a Heat Exchanger System Works
A heat transfer unit works by transferring heat from one fluid circuit to another through a heat exchanger while pumps, valves, sensors, controls, and other components regulate the process. The two fluids normally remain separated, and heat passes through a conductive heat-transfer surface such as plates or tubes. Understanding the heat transfer unit working principle […]
Heat Exchanger Nameplate and Model Identification: How to Read, Verify, and Replace Correctly
A heat exchanger nameplate and model identification is the fastest way to confirm what unit you have, what it was designed to do, and what you need to order as a replacement. The nameplate gives you design pressure, design temperature, flow rates, material of construction, and the manufacturer’s model code — but only if you […]
Heat Exchanger OEM Manufacturing: How Can Brands Find the Right Factory?
If you sell heat exchangers under your own brand, finding the right OEM manufacturer is more important than simply finding the lowest factory price. A reliable OEM partner should be able to do more than manufacture a product. The factory needs to understand your specifications, manufacture consistently, control quality, protect your product information, meet delivery […]
Custom Heat Exchangers: How to Design for Special Operating Conditions
A catalog heat exchanger covers maybe 70% of industrial duties. The rest — high pressure, aggressive fluids, tight footprints, heavy fouling — has to be engineered from scratch. That is where projects stall, because the design questions come before the commercial ones. Here is how custom heat exchanger design actually works when the operating conditions […]
Plate Heat Exchanger Selection Guide: How to Choose Compact and High-Efficiency Units
A plate heat exchanger can cut footprint by 70% or more compared with a shell and tube unit. It can reach a 1°C temperature approach. It can recover heat that other exchangers cannot. But the wrong plate heat exchanger will foul fast, drop pressure, leak at the gasket, or cost more to maintain than it […]
Shell and Tube Heat Exchanger Cleaning Methods: What to Do When Fouling Blocks Flow
Fouling does not announce itself. It shows up as lost production. The outlet temperature drops. Pressure drop rises. Pumps work harder. Steam or cooling water demand climbs. If you wait too long, tubes plug, gaskets leak, and the bundle may crack. Cleaning a shell and tube heat exchanger is not just maintenance. It restores heat […]
Shell and Tube Heat Exchanger Selection Guide: How to Choose for High-Temperature, High-Pressure Service
For process industries across North America and Europe—including oil refining, petrochemical manufacturing, power generation, and specialty chemical production—shell and tube heat exchangers are the workhorse of high-temperature, high-pressure (HTHP) thermal operations. These units handle feed preheating, product cooling, waste heat recovery, and process condensation under conditions that would quickly destroy gasketed plate, spiral plate, or […]
Exploring the Versatility of Heat Exchangers in Industrial Applications
Introduction to Heat Exchangers Heat exchangers are vital components in various industrial processes, designed to facilitate efficient heat transfer without mixing fluids. Among the types of heat exchangers, the gasketed plate heat exchanger and the brazed plate heat exchanger stand out for their adaptability and high performance. Understanding these options helps industries choose the best […]
