ARC Operation : Aerosol cans are loaded into the staging hopper Operator presses start on HMI which activates the aerosol can crusher A clearing cycle is first engaged to confirm that all residual cans left in the chamber are cleared Cans are loaded from the hopper automatically and placed in the crushing chamber Cylinder crushes can.  All residual liquid in can is discharged to a knock out 55 gallon drum. All vapors are pressurized through the knock out drum and into the dual inline carbon beds The empty crushed can is discharged directly underneath ARC-250 to a 55 gallon open drum or pail. When the system detects that can has been crushed and discharged, it releases another can for crushing. The cycle repeats

Other ARC features:

• The system monitors the exit/vent port of the last inline carbon bed to confirm that carbon bed is not releasing vapors to atmosphere.  If vapor is detected, the system will alarm, disable and display message on the HMI indicating that the carbon beds need attention or need to be replaced.
• Cylinder positioning sensors detect jam which will automatically engage operation to release the can from the jam and discharge it.
• Maintenance screen displays manual activations of all instrumentations on the system. This allows maintenances to manually activate all functions on the system. For example, maintenance presses the button "Seal change" on the maintenance screen which enables the cylinders to adjust and move to a position which allows access to change seal with ease.
• Life cycle counters keeps a count of how many cans have been crushed through the life of the equipment.
• Daily cycle counters keeps track of how many cans are crushed in a day. (This can be reset)
• Carbon filter change cycle counter allows you to determine when the last carbon bed was changed.  A suggested set point will display a message on the screen advising you to change the carbon beds.

Safeties:

• Motor overload/current protection
• Proximity sensors confirm positions of safeties so that operator can be out of harms way.
• Safety timers
• Alert messages
• Hard stops when hopper is moved out of position when system is in operation. System does not resume crushing waits for hopper to return to position and alarm reset on HMI screen.

ARC Chamber Wash Option:

The chamber washing option of the ARC-250 is designed to wash the aerosol crushing chamber clean of paint or remnants residue.  It is designed to maintain clean and free operation with the chamber along with extending seal life of cylinders seals. This feature is highly recommended.

Wash cycle operating procedures:

• The ARC-250 crushes XXXX amount of aerosol cans (Adjustable in setup menu)
• Once set point XXXX has been reached and exceeded, the chamber wash feature is energized.
• Wash fluid which is stored in a wash fluid holding tank is suctioned into the crushing chamber by means of the crushing cylinders.
• Both crushing cylinders energize in a back and forth motion which agitates the fluid within the wash chamber.
• After 5-7 swishing motions both cylinders are forced towards each other to generate positive pressure.
• The solvent that was in the wash chamber is forced back into the wash fluid reservoir for re-use.
• The positive pressure assists in discharging all remaining fluid in the crushing chamber to our knockout pot which is designed to store the aerosol can residual liquid. All vapors are pushed through the knockout pot and towards inline carbon beds where it is absorbed.
• After the discharge is complete the system returns back to its home position
• 3 seconds later the system resumes aerosol can crush.
• We also reset a counter so that when XXXX aerosol can are crushed again, the wash cycle will repeat.
• This cycle takes approximately 15-60 seconds to complete depending on operator set points.  Normal times average around 15-20 seconds.
