Features:

Closed water cooling system with proximity sensors control the flow and temperature of cooling water lines
Software enables programs to form heating-cooling, each of which comprises a sequence of independent segments, defined by three parameters: the increment of the voltage on the segment length of a segment of time and limit the voltage on the segment. It is possible to maintain these programs in the electronic memory of industrial computer. The software implemented the ability to "hot" switch from one program to another.
Control and monitoring provides a fully controlled by the user on the software and hardware levels of crystal growth process
Implemented the ability to control mechanical parts installation, implemented the ability programming parameters of the heater power
Furnace is equipped with preinstalled software on a perpetual commercial license
"hot" switch between automatic and manual types of control, at any moment you can stop the execution of the current program is automatically carried out the process and manually setting the new parameter set to continue process in automatic mode
Control and monitoring of the crystal growth is able to save all existing programmed parameters of the growth process in the nonvolatile memory.
Software is the preservation of all operator actions and changes all the setup parameters in nonvolatile memory.
