Most modern hydronic heating and/or cooling systems are closed systems that must be maintained at some minimum pressure. This would seem to be a simple concept, but it is surprising how often a lack ...

A pressurized glycol reboiler, first used at a Shell Oil Co. South Louisiana plant, is effective in controlling volatile organic compound (VOC) emissions from glycol gas-dehydration systems. The ...

Pressurized systems at Michigan Technological University include everything from small, unheated, low-pressure laboratory setups to large, extremely high-pressure heated metal vessels weighing several ...

Using dry nitrogen to pressure test a system is a very effective method of verifying a system is leak-free. In fact, I believe it is more reliable than using a standing vacuum test typically performed ...

IN LAST MONTH'S column ("Active and passive solar pre-heat systems," pg. 36), the final system we addressed was the closed-loop pressurized system. One of this system's major Achilles heels is the ...

Longtime professionals in the hydronic heating industry know that safeguards ensure optimal system performance and prevent catastrophic failures that can cause significant water damage. Proactive ...

Conventional district heating systems are generally designed around the load. However, an alternate approach would be to design around potential heat sources, including the waste heat from power ...
