The VRE dynamic fluid temperature control system is a dynamic fluid temperature control device that utilizes compressor cooling and electric heating to increase temperature. It can monitor the temperature changes of the liquid in real time and adjust the temperature by controlling the flow of the liquid. Compared with the ZTM series refrigeration and heating cycle devices, it has a wide temperature control range, high display resolution, large heating power, and high circulating pump pressure.
Product Features
