A major U.S. sugar producer has several hundred pumps throughout the plant. These pumps are either using packing, which requires constant maintenance or using mechanical seals, which require a water supply to cool and flush it. In the latter instance, the water is usually either returned to a seal water tank or dumped to drain. Any water that ends up on the floor or in a drain finds its way back to process and must be evaporated (large cost) or sent to wastewater (even larger cost). Because of this, any unnecessary water flow that can be cut from the process is beneficial.
- This plant faced several challenges prior to their adoption of EcoFlow valves:
- The plant could not use mechanical seals on their pumps due to the large water demand and up-front expense of a closed recirculation system.
- Packing was used in all pumps instead of double mechanical seals, causing leaks and constant maintenance.
- Expensive seals were damaged every year due to accidental dry running.
HOW OUR VALVE HELPED
ThermOmegaTech® EcoFlow valves were placed on the seal water outlet of their pumps’ double mechanical seals to control the seal water temperature…

Modern Pumping Today interviewed our Vice President of Engineering, Nick Tallos, on the role thermal relief valves play in potable water systems
MPT: What applications are the ThermOmegaTech range of thermal relief valves designed for?
Nick Tallos: The primary application we found for one of our valves, which is used as a thermal relief valve, is for domestic water supply booster pumps—so we’re not talking about chemical or processing pumping with this application; the focus is on potable water for buildings. And in this application, we discovered that the pumps need to be sized for maximum demand, and they have to be run to maintain pressure throughout the building. In other words, you can’t shut it off…
MPT: How would you best describe the benefits of the ThermOmegaTech range of valves? What are your customers looking for?
Nick Tallos: We’ve had customers report that idling pumps can sometimes elevate water temperatures to what we’d consider standard for hot water taps or even scalding hot. So building managers are obviously concerned about someone in their building turning on what should be a cold water tap and unexpectedly getting hot water…
MPT: How important is customer feedback to your product offerings? What do you hear from your customers that you put into your products?
Nick Tallos: We hold customer feedback at a very high level, especially during product development. Over the years, we’ve learned that the customer wish list makes a pretty good place to start whenever we’re deciding which features should be included on a valve—whether it be pipe sizing, valve size, flow rate. There are so many applications where a self-operating valve link to temperature controls prove beneficial, even separate from pump relief, that we greatly value what our customers bring to the table…

From Plumbing Magazine, Hydronic Heating Systems – Drain-tempering Valves Limit Discharge Temperatures
Problem: Balboa High School, part of the public school system in San Francisco, California, needed new low-pressure steam boilers that limited maximum drain discharge temperatures.
Solution: Guttmann & Blaevoet Consulting Engineers designed the project, with Tünde Munz, P.E., LEED AP and Principal of G&B, initiating the solution. As required by code, these low-pressure boilers must have relief valves. Due to safety concerns about venting steam near where students are congregating, the designer chose to vent the relief valves into suitably sized piping, which runs to a floor drain inside the boiler room. To comply with plumbing codes limiting maximum drain discharge temperatures, the designer chose to add self-operating, thermostatic, drain-tempering valves that only inject cold water into the vent lines when the relief valves activate. These drain-tempering valves from ThermOmegaTech automatically detect when the drain temperature is above allowable levels and discharge just live casino australia enough water to temper drain flow below the allowable 140 degrees F.
Result: The drain-tempering valves require no outside power or signal, which made the installation efficient, clean, relatively simple and cost-effective.

Exposed pipes can be the biggest headache for plant managers and maintenance personnel in the harsh winter months. Any sort of pump, valve, or process pipe that is exposed to harsh effects of the Winter is susceptible to freezing and bursting. As you can imagine this can create havoc in critical systems.
There are many ways to heat these pipes, but in the extreme climates, one of the most effective methods is to apply glycol tracing. Since glycol does not freeze and doesn’t require any special handling in environments that need to be explosion proof, it makes it an ideal solution.
Glycol has a very low freezing point which allows it to remain in liquid phase, even in very cold temperatures. The exceptional thermal transfer characteristics also make it the obvious choice for a cost effective heating medium.
How We Can Help.
ThermOmegaTech manufactures many valves that control the flow of, and maximize the effect of glycol through these systems. Our most popular valves for use in glycol tracing include HAT and TV/HAT.
Our valves are not reliant on electricity to operate. To regulate the flow of glycol, each of these valves contains a thermostatic element inside that modulates open or closed to maintain a constant discharge temperature. Each of them improves system efficiency by automatically varying the rate at which glycol is pumped through the system.
For years, manual balancing valves have been the industry standard in regulating the flow of recirculating domestic hot water systems. Particularly in large, populous commercial buildings, such as offices, hotels and multi-dwelling housing, maintaining perfect hot water distribution was very challenging until Pennsylvania-based manufacturer ThermOmegaTech®, Inc. launched its self-operating temperature actuated Circuit Solver thermal recirculation valve (Circuit Solver) and set a new standard.
“Even people who are very knowledgeable with years of experience in the industry are impressed with what Circuit Solver can achieve,” shares Nick Tallos, vice president of engineering for ThermOmegaTech and 40-year industry veteran himself. “They ask, ‘where was this 20 years ago,’ and call Circuit Solver a game-changing technology.
However, ThermOmegaTech is no stranger to gamechanging products. Since the company was founded by the late Fred Pirkle in 1983, it has been solving temperature control problems all over the country and the world.
“I was working with Fred before he started ThermOmegaTech,” recounts Tallos. “He was working as a sales representative for another company when he was offered a position in product development in Pennsylvania. A few years later, in the early 1980s, he decided to start his own company.

The facts are frightening – especially since the problem can be avoided.
Consider this: As many as one in 10 patients hospitalized in the U.S. contracts an infection, according to the Wall Street Journal. That means nearly 2 million patients annually are infected by bacterium or other agents.
The end result?
The cost is nearly 100,000 deaths and $6.5 billion in overall losses.
