A large unit that cools compressed air using refrigerant gas and further reheats it to extract dry air. In heat exchange with air or gas, the thermal conductivity efficiency is significantly lower compared to water. Using a typical liquid/liquid plate heat exchanger results in pressure loss dominance, leading to an unnecessary increase in the number of plates, making it cost-ineffective. Generally, a copper tube + aluminum fin structure is used, but the contact points between the fins and the copper tubes can also become thermal resistance. How to efficiently transfer heat to air... When considering this issue, improving thermal conductivity can be achieved by using an aluminum thin film + fully brazed structure. *For more details, please contact us.

We propose energy-saving measures using heat exchangers for waste heat recovery. We contribute to the reduction of CO2 emissions and energy consumption across a wide range of industries and fields. We also have products that can be introduced in environments where oil mist and VOCs are generated. Please feel free to consult us. ★ We are distributing a collection of case studies. You can view it immediately via "PDF Download." 【Featured Cases (Excerpt)】 ■ Achieved clean exhaust by reducing exhaust heat temperature and removing oil mist ■ VOC measures and heat recovery in a drying oven at a painting factory ■ Utilized exhaust heat from the furnace for a steam unit heater, reducing heating costs ■ Used exhaust heat from boiler blowdown water to preheat feed water ■ Combined two heat exchangers to thoroughly recover heat from low-temperature steam, etc. * For more information on waste heat recovery and energy saving, please feel free to contact us.

The "HEATEX Series" is a sensible heat exchanger optimized for air/air applications, featuring plate shapes made of aluminum or stainless steel. It addresses the issue of excessive pressure loss that can lead to unnecessary increases in size and cost through improvements in shape and pitch. Due to its versatility, it can be applied in various forms such as fixed and cassette types, making it suitable as a heat source for heat pumps, capable of handling up to 100,000 m³/h and 200°C. 【Features】 ■ High airflow + compact design / suitable for hygiene management facilities ■ Optimized plate design ■ Air-specific design pattern ■ Immediate responses possible due to MDI, a thermal design standard in Japan *For more details, please refer to the PDF materials or feel free to contact us.
