Wigam's 13003105 station offers a fully automated process that significantly simplifies maintenance operations on CO2 air conditioning systems:

• Automatic refrigerant recovery with pressure control
• Programmable vacuum cycle to eliminate moisture and contaminants
• Precise refrigerant charging with automatic compensation
• Integrated leak test to verify system integrity
• Automatic oil management (separation and injection)
• Air conditioning system diagnostics with detailed reports

Operational Advantages for Professionals

The use of this Wigam unit offers numerous benefits to refrigeration technicians working on bus air conditioning systems:

• Significant reduction in intervention times thanks to automation
• Increased safety when handling high-pressure refrigerant
• High precision in system charging, essential for CO2 systems
• Complete documentation of operations thanks to the integrated printer
• Compliance with the latest environmental regulations on refrigerant use
• Intuitive user interface that reduces the need for extensive training

Specific Applications for the Transport Sector

This unit has been specifically developed to meet the needs of the public transport sector, where R744 air conditioning systems are becoming increasingly common due to the low environmental impact of CO2 as a refrigerant. It is particularly suitable for:

• Scheduled maintenance of urban and interurban bus air conditioning systems
• Repair interventions on transcritical CO2 systems
• Retrofitting systems from traditional refrigerants to R744
• Specialized service centers for public transport
• Company fleets with vehicles equipped with CO2 systems

Sustainability and Regulatory Compliance

The use of R744 refrigerant represents an important ecological choice, as CO2 has a global warming potential (GWP) of 1, drastically lower than traditional synthetic refrigerants. This Wigam unit fully supports the transition to more sustainable refrigerants, in line with European F-Gas regulations and the goals of reducing environmental impact in the refrigeration and air conditioning sector.
