SUNDI 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.

Use high temperature resistant low-temperature magnetic drive pump or a leak-free high and low-temperature shield-driven pump, reduce the risk of system leakage. At the same time, the system has the advantages of low noise and big traffic flow.

Technical Parameters of Dynamic Temperature Control System
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.SUNDI principle

Microchannel reactor thermostatic control, small temperature control system, steam - feeding system temperature control, material low temperature aging test.
The thermostatic control of the combined chemical cold source heat source, the cooling heating of the semiconductor equipment and the heating temperature of the vacuum chamber are controlled.



Advantages and Maintainence of Industrial Chiller Units

Water chiller is widely used in plastic, electroplating, electronics, chemical industry, pharmacy, printing, food processing and other industries.

Cold water machine is commonly known as freezer, refrigerating machine, ice water machine, freezing water machine, cooling machine etc., because of its wide range of use. Today, we are going to give you a detailed explanation of the advantages of Industrial Chiller Systems SUNDI -25℃ ~ 200℃/300℃

Accurate temperature control ability
For industrial chiller system products, accurate temperature control ability is very important. For example, our industrial chiller uses imported microcomputer digital temperature controller. High quality of thermostat products not only helps accurate control, but also energy saving and environmental protection.

High heat exchange efficiency
According to Mr. Li meihua, the advantages of shell-tube condenser and evaporator in industrial chiller are simple, easy to maintain and highly efficient heat exchange. For example: "chuangshengtai" series products adopt the company's unique design of shell tube condenser, evaporator. Its heat transfer performance is 20% higher than that of ordinary products. Also it has the features of less loss of the cold quantities, easily returning oil. And the heat transfer pipe will not be frostbitten. Therefore, its comprehensive cost efficient is the best.
