Change the control settings of the method, the response as soon as possible in the process of the system lags behind be the smallest system overshoot. Controlled by two PID (PID is a variable in each group) control loop structure, known as the two sets of control loops: the main circuit and from the circuit, the main control loop from the loop output as the settings. The system with feedforward with PV, the master PID loop operation results of the PV output and feedforward signals as the composite of the settings from the control loop, through such control of the temperature gradient, to ensure the accuracy of temperature control system.

Application Area of Laboratory Chiller in the Vacuum Glove Box
The glove box (vacuum glove box) is a laboratory equipment that fills the box with high pure inert gas and circulates the active substance. It is a lso known as vacuum glove box, inert gas protection box, etc. The main function is the removal of O2, H2O and organic gas.
Vacuum glove box are widely applied to no water and no oxygen, dust-free ultrapure environment, such as lithium ion battery materials, semiconductor, super capacitor, special lights, laser welding, brazing, material synthesis, OLED, MOCVD, etc. It also includes biological applications such as anaerobic culture and cell hypoxia culture.
Our laboratory chiller SUNDI -70 ℃ ~ 250 ℃ is a universal precision cold water machine, with stainless steel piping system, high performance controller, multistage centrifugal pumps, and the built-in filter unit. It can meet various needs. Built-in multiple detection and alarm function can provide water flow alarm protection, water level alarm protection, overtemperature alarm protection. The RS485 serial interface and supporting equipment communication can be provided according to the user's needs, and can fully manage all the equipment of the chiller. The parallel interface can be provided, and the switching value of the alarm signal can be controlled by the switch signal.
