Closed Loop Water Treatment

Closed Loop Water Treatment

Posted by Bob Schneider on in Engineering

In a central plant system, there are two types of water piping loops: closed and open. An open loop is from the chiller to the cooling tower. As the water flows through the tower, it is open to the atmosphere. Because of evaporation at the cooling tower, city water is introduced to replace the evaporated […]

What’s a Watt? (And Other Electrical Fundamentals)

What’s a Watt? (And Other Electrical Fundamentals)

Posted by Mike Ruff on in Fundamentals

Basic electrical calculations involve three parameters, volts, amps and watts. Volts Here in the United States, we design according to specific voltages provided by our utility companies. In residential construction, we often have 120/240V, single phase, 3-wire, while in commercial construction we typically have 120/208V, 3 phase, 4-wire or 277/480V, 3 phase, 4-wire (although older […]
