In today’s economy there are many small office, retail, and tenant fit-out work jobs than large expansive projects. These smaller projects come with tighter budgets. Here is a tool you may not be aware exists. Bell and Gossett ECO-CIRC under sink recirculating pump available for tank type water heater as well as tank-less systems. High efficiency and lead free brass construction.
The objective of water treatment is to:
*INHIBIT CORROSION, prevent mineral scale & control bacteria, biofilm & legionella. In this Monday Morning Minute, we will discuss the technology and the effect that pulse technology via the Griswold Wave product provides specific to corrosion inhibition.
The objective of water treatment is to: *CONTROL BACTERIA, BIOFILM AND LEGIONELLA, Inhibit Corrosion, & Prevent Mineral Scale. In this Monday morning minute, we will discuss the technology and the effect that pulse technology via the Griswold Wave product provides specific to microbial control.

Today’s building owner’s have many opportunities to improve water use efficiency. ASHRAE Standard 189.1 identifies a few areas to focus on reducing water use specific to cooling towers. The last four issues of Deppmann’s Monday Morning Minutes has discussed specific strategies to improve water use efficiency using current Cooling Tower and Advanced Water Treatment technology advancements in design. [Read more…]
Most new chillers can now handle variable flow through the condenser providing many opportunities for operational savings. As the cooling tower is an integral part of this system, it is important to understand the effect of flow rate changes and how to insure your cooling tower can provide optimal savings while operating [Read more…]
In this issue, we will discuss the changing requirements specific to “cycles of concentration” in cooling tower applications. In addition, we will review the effect of increasing cycles of concentration and provide solutions to improving these results. ASHRAE Standard 90.1-2010 code change effective 10.18.2013 states [Read more…]
In this issue, we will discuss blow down and cycles of concentration. In addition to water emissions caused by evaporation and drift, cooling towers require blow-down to control the levels of dissolved minerals re-circulated in the cooling tower. These losses are offset or balanced by make up water to both maintain the level of water in the tower and more importantly, [Read more…]
Open loop evaporative type Cooling Towers by design create emissions of evaporation and drift. Drift emissions from open-loop evaporative type cooling towers are unavoidable. Stand next to a conventional cooling tower and it feels like you might be taking a shower. The amount of drift can vary depending on tower design and will include any water treatment added (chemicals). [Read more…]
The Xylem Bell and Gossett manual TEH-1209 has a great detail for filling the tower water system piping. Many times the cooling tower pump is used to take water from the tower pan and fill the condenser and piping system. This can lead to pump problems due to the large flow rate of the pump compared with…
