By incorporating a recommended maintenance schedule of the Hydroheater, processing and performance issues can be a thing of the past, helping ensure peak output results.
Hydroheater/Jetcookers need little maintenance as compared to other industrial heating systems. However, proper maintenance and adjustment of parts will extend the life of the heater, improve process efficiency, and ensure the Hydroheater performs precise heating needs. Hydro-Thermal’s specialized field technicians, machinists, engineers, and training personnel can help operate and maintain a direct steam injection heating system. To prevent unintended shutdowns or the potential for extended outages, Hydro-Thermal recommends using a schedule for preventive maintenance.
- Examine Hydroheater for any leaks of steam or water.
- Verify the temperature control loop is working correctly and maintaining a temperature within specified requirements.
- Look for indirect signs of wear, i.e., failure to shut off or effectively control the temperature.
Make sure to order repair and seal kits several weeks in advance of your annual maintenance shutdown to assure on-time delivery of all items.
- Disassemble heater and check parts for wear
- Examine discharge piping of heater for unusual scale buildup.
- Replace all seals
- Replace stem packing
- Replace worn components as needed
These suggestions will help owners of our highly engineered DSI systems to keep them performing at ‘like new’ levels and provide a predictable maintenance schedule and budget.
In a world where throw-away culture has become the norm, it is rare to say of a piece of equipment lasts longer than a decade.
Keaton Leach, a Process and Project Engineer at an Ethanol production facility, can say this about two Hydro-Thermal K514 Hydroheaters at his facility. According to Leach, these units were installed to- “help sterilize and saccharify corn starch before the liquefaction process.”
The Hydroheater is a robust piece of equipment that is designed to work for decades, but to ensure it is working at optimal performance it is essential to have annual maintenance. On the topic of regular maintenance, Leach explains, “The maintenance of our equipment has been pretty straight forward. Yearly re-gasketing and inspections have been handled by the Hydro-Thermal technicians, and our maintenance technicians can handle any repairs that are required between services.”
Keaton’s company recently had a visit from Hydro-Thermal’s service technicians. “Our most recent visit for the yearly repair kits and inspections went very smooth,” Leach said. “Both technicians were very knowledgeable about the equipment, and neither of them was the ‘pushy salesman’ that wants everything with a little wear immediately changed. We appreciated the honest opinions of what was worn and how much longer it may last before causing larger issues.”
