How to add glycol to a closed loop system
NettetGlycol makes closed loop water feel very slippery and it becomes sticky as the water dries. We recommend using ethylene or propylene glycol at 50% by volume. This will afford a freeze protection to -25° F (below zero).The table below will help you calculate how … NettetWater in a hydronic heating system should be free of air bubbles and dissolved gases, such as oxygen and nitrogen. Dissolved gases in a hydronic systems come together to form microbubbles. These microbubbles are very difficult to remove due to their low velocities in the system. If we don’t removing these dissolved gases, many problems …
