ZLF- N
the primary cooling source or the main heat source is used to proportionally regulate the system flow to control the heat entering the reactor jacket, and a set of heat exchangers for heating or cooling to control the temperature rise or fall.

ZLF- NS
in addition to the ZLF-N function, a set of heat exchangers is added for high temperature cooling

ZLF- NH
Add electric auxiliary heating function in addition to ZLF-N function

ZLF- NSH
in addition to the ZLF-N function, a set of heat exchangers is added for the high temperature cooling function and the electric auxiliary heating function.
