Can I directly flow fluid whose temperature I wish to control (e.g. cutting oil, seawater, etc.) from?

An SMC chiller employs an indirect temperature control method, so it cannot directly control the temperature. Flow the circulating fluid whose temperature has been controlled, and control the temperature of the heat source on the opposite side according to the temperature of the circulating fluid.
(Note: When using the chemical thermo-con HED series, you can directly control the temperature of the chemical liquid.)
