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 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.

“I turned on the water in the shower and waited for 10 minutes. Warm water finally started flowing, however it never lasted more than a minute and alternated mostly with cool to cold water.”
That’s the exact quote extracted from an online review of a guest who rated a hotel in Pennsylvania on Tripadvisor.com. The reviewer gave the hotel a rating of two out of a possible five. The site is full of similar comments from guests complaining about how long it took them to get hot water when they wanted to take a shower or wash their hands. Continue reading
In December 2009, a well-known manufacturing plant experienced a safety incident in which an employee was severely burned. The employee was exposed to a caustic chemical that sprayed out of a spigot and came in contact with exposed parts of his neck, hands, and arms. He was rushed to the nearest safety shower and thrust under a deluge of bone-chillingly-cold 40°F water. Due to the extremely frigid water, his body’s natural reaction was to leap out before being completely rinsed of the harmful irritant. He was then transported to the medical office where the combination of not being fully cleaned of the chemical and the length of travel time lead to worse burns than there should have been.
The American National Standards Institute (ANSI) Z358.1-2009 is used to help plant managers and safety professionals comply with the Occupational Safety and Health Administration (OSHA) regulations requiring employers to provide a safe workplace. This ANSI Standard establishes the universal minimum performance required for all eyewash and drench shower equipment used in plants. It states that all flushing equipment must be located in easy-to-reach areas, with the eyewash station or shower accessible within 10-seconds. This has become referred to as the 10 second rule. Additionally, eyewash stations and showers must be installed in well-lit and marked areas with a minimum flow rate of .4 GPM at 30PSI and 20 GPM at 30PSI respectively. The ANSI Standard also includes other design and operational specifications to assure that the safety showers and eyewashes are easy to use even in the case of an emergency by a victim with compromised mobility. Such features include valves that are easy to activate and will stay open once activated without having to hold a valve or handle open. OSHA regulations that apply to safety shower eyewash stations expand on the ANSI Standard requirements in certain high risk operations. For example, if open vessels containing hazardous substances are present, OSHA requires specialized safety shower and eyewash equipment to address the higher risks.
Keystone Edge recently profiled CEO Jim Logue for their “Innovation & Job News” section. Jim discusses ThermOmegaTech’s journey into Lean Manufacturing and the growth that we’ve seen with it.
“A few years ago, when CEO Jim Logue joined ThermOmegaTech, a Warminster valve maker, he found a solid, old-line manufacturer. Still, he recalls, the assembly shop and the machine shop were not clearly communicating, leading to inefficiencies and delays.
No more Since 2010, Therm has been “on a lean journey,” says Logue. Mentored by the Delaware Valley Industrial Resources Center, Therm has taken steps to eliminate waste in its manufacturing processes and, equally important, change the plant’s culture by sharing information and ensuring that all 60 employees understand the big picture.”
“We basically have empowered every employee to have a say in how to improve their work area, or what they see elsewhere,” says Logue. “It gives purpose to coming to work.”
Since adapting the principles of lean manufacturing, Logue says, people are working better and smarter and operations are more coordinated and efficient. The company has seen 70% growth in revenues in its top products and has grown jobs by 10%. Logue anticipates adding another three positions in the next six to 12 months.
The Circuit Solver Balancing Valve was recently featured in both HPAC Engineering Magazine, as well as Contractor Magazine.
HPAC Engineering is the leading mechanical systems engineering publication and voice of leadership in the buildings industry.
The Circuit Solver self-actuating temperature-control valve is designed to solve the problem of domestic hot water not being rapidly delivered to all parts of a building. When entering water temperature is below the valve’s set point, a thermal actuator begins to open the valve to establish a flow rate that will achieve set point. If the water temperature exceeds the set point, the valve begins to throttle back to find the current equilibrium point. This constant, automatic response to water temperature enables each hot-water branch to quickly and consistently deliver the correct temperature to each connected fixture. The all-stainless-steel valve complies with California AB1953 and meets NSF-61 standards. —Therm-Omega-Tech
