Cooltech equipment consists of 3 large blocks: an electronic block - for control of all inputs and

outputs of the equipment, a refrigeration block

– for cooling the hot part of the peltiers and a

vacuum block - for stopping blood circulation in the treated area, avoiding heating the area for

better results. Each of these blocks is described in more details below.

Electronics:

The electronic block consists of 2 CPUs: the Main and TFT control board.

Main CPU

TFT control board

Main CPU is located inside the electic cabinet of the equipment (on the left side, viewed from the

front), while TFT control board is mounted underneath the display.

TFT control board is responsible for displaying the necessary images on the screen, analyzing

and informing the Main CPU, when the user enters any data and commands on TFT.

All images, graphics and active zones for the screen are stored on a microSD inserted in TFT

control board.
