Key Advantages for Industrial Applications

  • Superior Heat Transfer Capability: The utility side hold-up volume is 170 times that of the process side. Combined with the ultra-high specific surface area of microchannels, it instantaneously dissipates the massive heat generated by violent reactions.

  • High-Pressure Safety Design: The process side supports operating pressures up to 5 MPa, making it ideal for harsh high-temperature and high-pressure microreaction processes.

  • Ultra-low Hazardous Inventory: With a process hold-up volume of only 0.069 mL, the transient volume of hazardous reactants online is minimized, significantly improving inherent safety (inherently safer design).
