It’s not uncommon for molds that require cleaning to be worth hundreds of thousands of euros. Coolingcare machines are equipped with dozens of sensors and safety algorithms that monitor the process in real time, ensuring stability of the process. In the case of sudden, unexpected event, such as i.e. leakage, the computer stops the cleaning process and notifies the operator.
Here is a list of all safety modules installed in CA units:
| SAFETY | |
| a set of sensors and algorithms ensuring stable and safe operation | blow-through algorithm (ramp) – protects the compartment with a sudden pressure drop, the pressure increases gradually, thus minimizing the risk of damage to the partitions and other elements of the cooling system |
| algorithm for verifying the correct reading from all pressure sensors – allows verification of the presence of residual pressure in the system, thus eliminating the possibility of liquid flowing back into the pneumatic system when the valve position is changed | |
| the machine informs the operator about the presence of residual pressure in the system, so he can release it manually and safely disconnect the hoses | |
| Each valve has a position control sensor – thanks to this function, the operator cannot start the machine in an incorrect configuration | |
| Algorithm for identifying the problem of circulation blockage if the operator misses the patency test – if the flow rate during diagnostics is very low, the machine will inform the operator about the potential blockage and exclude a given section in automatic mode. If the canal is blocked, they should be cleaned individually in manual mode. | |
| leakage detection system | ultrasonic probe in the cleaning tank allows for precise, real-time measurement of liquid level. The operator can define an allowable volume drop not causing an alarm. This can be as low as 10mm (an equivalent of approx.1L of liquid). If the level of liquid in the tank drops by thsi value, the machine will automatically stop the process and send a text message to the operator informing him about a possible leakage. |
| liquid level measurement in the tank | it can be a precise measurement (ultrasonic probe measuring the exact amount of liquid) or floater based measurement, which gives a rough estimation |
| liquid temperature control combined with automatic heater activation/deactivation | temperature sensors (one in the heater, the other on the filter housing) |
| Heating element damage control | the machine is protected by a thermostat placed on the heating element and a software protection that disconnects the heating if the permissible temperature is exceeded. |
| identification of faulty phase connection | the machine detects the absence of any of the phases or the incorrect order of their connection, this prevents damage to the centrifugal pump |
| Control of the continuity of the liquid flow through the heater system | The flow heating system is connected to a dedicated diaphragm pump that forces the circulation of liquid through the tank in which the heater is placed. The algorithm verifies whether the heating element is fully immersed in the liquid and whether the liquid flow rate is appropriate. |
| moisture detection in pneumatic system | if the presence of water is detected in the compressed air, the machine will block further operation. This is to protect the pneumatic system of the machine, which is the most sensitive element of the entire structure. |
