Glycol is like antifreeze and is used in chilled water piping loops to prevent freezing. Everyone knows when the pipes freeze they also break and start leaking. Having antifreeze in a chilled water loop is important to prevent freezing. (more…)
Water Tower Pumps and Controls | Pumping Systems - Water towers maintain a ready limited supply of water for communities in the event the water main goes down. Many towers are used for emergency situations for the fire department to have water for fighting fires and for water fire suppression systems to have a supply of water for the emergency if it should arise.

Watts Backflow Preventers | Water Safety - Backflow preventers are necessary on water loops where the water is used in a hydronic loop that heats or cools the water through a boiler or chiller system. This Watts backflow preventer is installed on a large boiler system that heats thousands of gallons of water. The hydronic loops are designed to be hermetic. However, there is always some loss of water somewhere in the system.
For safety purposes to prevent the boiler from losing all of its water, a make-up water loop is connected to the loop. The make-up water feed needs backflow preventers installed in the pipe to prevent any of the boiler or chilled water from getting back to a domestic water feed for the make-up water. (more…)
