Significant cost reduction! "Insulation Heater" *Examples of problem-solving included

Output changes according to the surrounding temperature, providing uniform insulation! High quality with no maintenance needed for the heater! Aiming to reduce costs by 90% from approximately 10 million per month. *Example of problem-solving included.

Seido Electric provides a safe, self-regulating heater that has a long lifespan, can adjust its output according to ambient temperature, and can be used in hazardous areas. Since it saves temperature at the upper limit, it does not overheat and can maintain warmth evenly. Being electric, it does not require a boiler operator, offering significant cost advantages compared to hot water and steam systems, and has recently gained attention! **[Challenge]** A confectionery manufacturer was spending 10 million yen per month to melt chocolate and jam, which was costly and required a boiler operator. They requested to reduce costs, including labor expenses. **[Solution]** We replaced the existing hot water and steam systems with our self-regulating heaters, achieving a 90% cost reduction. The electric system can operate 24 hours a day, and since it only incurs costs for the necessary energy, the monthly cost dropped from 10 million yen to about 1 million yen, roughly one-tenth of the usual cost. Additionally, since a boiler operator is not needed, expenses were significantly reduced, much to their satisfaction. *You can download the "Heater and Boiler Troubleshooting Guide" as a PDF!*
