Product Details


It is specially designed and developed for the characteristics of small liquid holding capacity, strong heat exchange capacity, and large pressure drop in the circulation system of the microchannel reactor.

1. Optimize temperature sampling and response speed, specially design control algorithm, can respond quickly to stable temperature control.
2. Enhance the design of the circulating pump capacity to meet the high pressure drop requirements of the reactor.
3. Continuous high temperature cooling technology to meet the requirement of stable operation when the temperature control is required for high temperature exothermic reaction.
