Plant Engineering and Plant Maintenance
Temperature control is a vital function in many industrial processes and equipment such as hydraulic and lube oil systems, pumps, safety showers, process lines, and other piping, valves, etc. Temperature changes can affect fluid viscosity in equipment and cause fluid in piping to freeze or overheat. Below are a few applications where temperature control plays a huge role in plant maintenance.
Heating Fluid Control
During the freeze season, piping needs to be winterized to keep industrial processes and equipment functioning optimally. An effective method to prevent these lines from freezing is steam tracing the piping, however if the steam is not regulated this can become very costly.
Traditionally, plant maintenance personnel would turn the steam on to these trace lines just prior to the first expected day where temperatures might drop below 32°F (0°C) and not turn the steam off until there is no longer any chance of seeing these freezing temperatures (typically from October to April to most locations in the United States).
During this period of time, there will be many hours where temperatures are above freezing. Significant energy reduction can be realized if the steam is turned off during those warmer periods.
ThermOmegaTech® offers several options to automatically control the flow of steam through traced lines and eliminate live steam losses. Learn about the different methods here.
Cooling Fluid Control
Cooling control is critical for many applications and equipment in industrial plants, such as compressors, heat exchangers, electrical equipment, die-casting processes, molding, and many others, to prevent overheating.
Cooling jackets or coils may be used to prevent this overheating however if temperatures are not properly regulates you could be wasting money or miscalculate the cooling flow needed, effecting fluid viscosity.
ThermOmegaTech® has developed a multitude of solutions to maintain optimal process temperatures. Our self-operating thermostatic valves can automatically control the flow of cooling medium to economically remove heat from equipment or a process. Learn about the different methods here.
Thermal Relief for Pumps
Cold water supply pumps must be sized for maximum expected flow rates even though most of the time pumps are idling against a dead head or much lower than design flow. In these cases, the pump energy is transferred into heating the water in the pump casing.
When pumps run under such reduced flow conditions, the water temperature inside the pump casing can easily reach dangerous temperatures. The result can be damaged seals or pump damage. Another serious concern may be exposure of humans to the elevated water temperature from the pump when operating faucets, showers, and other water supplies. Human exposure to 140°F water can cause serious 3rd degree burns to skin and tissue in just 5 seconds!
ThermOmegaTech® offers multiple self-operating valves to reduce the water temperature in the pumps. The valves are installed into the pump housing to sense the water temperature and will automatically open when the temperature exceeds the set-point of the valve to discharge the hot water. The valves will automatically close when the water temperature falls back below the set-point to conserve water and reduce waste.
An essential component of plant maintenance in dairy, pharmaceutical, food processing, chemical and industrial plants is the cleaning of tanks and equipment with high temperature water to fight bacteria and grime.
ThermOmegaTech® offers a variety of thermostatically controlled washdown stations to deliver a high temperature wash at the operator’s set temperature. Designed to have a quick startup time and an even shorter downtime, our highly efficient mixing stations combine either steam and water or hot and cold water to provide a steady flow of hot water. All our stations are easy to maintenance when needed and built with safety in mind to keep personnel protected. Learn about the different options here.
