When engineers compare plate heat exchangers (PHEs) to shell-and-tube heat exchangers (STHEs), the conversation often centers on footprint, cost, or maintenance. Comparison between a PHE and a STHE But one of the most important — and most overlooked — advantages of plate heat exchangers is their ability to operate efficiently at much smaller Log Mean Temperature Differences (LMTD). This single characteristic drives a cascade of practical benefits that make PHEs the superior choice in a huge...

Sugar production is one of the most thermally intensive processes in the food and beverage industry. Whether it's beet, cane, or refining, every stage relies on transferring heat efficiently between juice, vapour, and steam streams. As Southern Africa's authorised Alfa Laval distributor, The Heat Hub supplies and supports the heat exchanger technology that sugar producers rely on to keep energy costs down without compromising output or quality. Pre-treatment: handling fibrous juice streams...

Industrial processes generate a lot of heat. Much of this heat is often lost to the environment. But what if we could capture that heat and put it to good use? Recovering waste heat is a smart way to save energy, reduce costs, and lower carbon emissions. This approach is especially important with the recent energy cost increase. Why waste heat recovery matters Process manufacturing industries like food, beverages or chemicals use a lot of energy. They often produce heat as a byproduct. This...
