The "MDI-DRT/MDI-DRS" is a shell-and-tube heat exchanger designed with corrugated tubes that minimizes scale adhesion. By switching from conventional straight-tube shell-and-tube designs to this corrugated shell-and-tube, the internal liquid is significantly improved in heat transfer efficiency due to the turbulent flow caused by the agitation flow. 【Features】 - The corrugated tubes generate turbulent motion, greatly enhancing heat transfer performance. - The internal liquid's heat transfer efficiency is significantly improved due to the turbulent flow caused by the agitation flow. - The performance increase due to turbulence rises by 2-3 times. - Increased efficiency directly leads to reductions in gas or electricity costs, which are the heat sources. - It can also be used as a steam/liquid heat exchanger. *For more details, please refer to the PDF document or feel free to contact us.

This product is a high-efficiency shell and tube micro heat exchanger made of all pure titanium with a thickness of 0.3mm. The issue in water/water design was that laminar flow caused by large diameter pipes led to a decrease in the boundary layer coefficient. By using small diameter ultra-thin tubes, we successfully reduced the low thermal conductivity in the laminar flow section, achieving a K value (overall heat transfer coefficient) of over 4000 W/m²·K. 【Features】 - Made entirely of titanium, all SUS316, and can also be manufactured using special materials such as Hastelloy and Inconel. - Designed to minimize contamination and ensure reliable operation. - Integrated structure with full welding. - Achieves high-efficiency design with fine tubes having an inner diameter of 2.0mm. *For more details, please refer to the PDF document or feel free to contact us.
