Using Glycol In Closed Loops | How to Use Glycol in
2019-2-26 · Can You Use Too Much Glycol In Your Closed Loop System? Since glycol has a lower specific heat than water, higher concentrations of glycol in your closed loop water will reduce the heat carrying capacity of the system. Too much glycol will, therefore, increase energy costs as the system works harder to accomplish the desired heating or cooling.
How to Optimize Your Closed-Loop Systems | 2018
2018-11-13 · It is important to specify filtration on closed-loop systems. If the system is dirty, you will decrease the efficiency of the heat exchanger equipment, which results in increased electricity and natural gas costs. Many operators may incorporate separate cartridge filters and bypass feeders into the closed-loop recirculation system.
