Company information
We specialize in the design of various heat exchangers and the recovery of unused heat (from hot springs, food factory waste heat, and sewage heat), offering energy-saving solutions from the perspective of heat exchangers.
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!
