[Case Study of Heat Recovery] Heating of Adjacent Areas Using Exhaust Heat from the Furnace
A case where the heat inside the equipment was exchanged with the cold air in the molding equipment area, reducing heating costs.
Until now, while discharging the hot air from the equipment with the furnace to the outside, the neighboring equipment was heated with steam, and as the room temperature dropped during winter, the required amount of steam increased, leading to higher steam costs. After implementing energy-saving measures, we used the plate-type gas/gas heat exchanger "HEATEX" to exchange heat between the hot air in the equipment with the furnace and the cold air in the molding equipment area, thereby reducing the heating costs of the steam unit heater. [Case Summary] ■ Used plate-type gas/gas heat exchanger "HEATEX" ■ The amount of steam saved is approximately 50 kg/h ■ Steam saved during winter 50 kg/h × 24 h/d × 30 d/m × 4 months = 144 t/year ■ Assuming the cost of steam is ¥6,300/t, the steam cost saved during winter ¥6,300 × 144 = ¥907,200 *For more details, please refer to the PDF document or feel free to contact us.

We optimize all types of heat exchangers, from high-efficiency plate heat exchangers to titanium exhaust heat recovery spiral heat exchangers. Furthermore, we offer a unique lineup of products, including high-efficiency compact heat pump chillers and large cooling components, addressing various unused energy sources such as exhaust gas, wastewater, seawater, and ultra-pure water. As experts in thermal energy, we respond to various inquiries related to heat exchangers. Specializing in the design of special heat exchangers and unused heat recovery (such as hot spring wastewater, exhaust heat from food factories, and sewage heat), we provide a range of energy-saving proposals related to "heat," from design to consulting. In this era where continuous energy saving is necessary for each factory, we also hold study sessions on thermal energy for employees and stakeholders. We can tailor the content to meet the needs and preferences of participants, covering explanations of heat exchangers, thermal energy, its utilization, and related concepts. We can provide proposals and consultations that align with on-site needs, so please feel free to reach out regarding any thermal energy matters. We offer energy-saving proposals to our customers through heat exchange!
