Smart charging machine \


The industry’s first smart charging machine, with never before seen features and advanced technology, NAVTEK‘“ brings Smart charging products to the HVAC industry. Conventional refrigerant charging operations use vacuum pump, manifold gauges, electronic charging scale, refrigerant tubing and other connection devices. It is dependent on the technician’s experience level and judgement to charge refrigeration systems. The conventional method is inconvenient, labor intensive, and it is difficult to ensure accuracy of the refrigerant charge. The high-power twin-cylinder vacuum pump, with ultra-high vacuum capability, rapidly evacuates the system to the preset vacuum level. The smart control precisely measures the system’s vacuum and digitally displays the vacuum level. After reaching the preset vacuum level, it automatically conducts the dry operation and leak detection. When the unit confirms  the system is under proper conditions, the intelligent control automatically starts the Charging function with precise control of the predetermined refrigerant charge, and turns off the system once charging is complete. The NAVTEK‘“ smart charging machine enables you to automatically, accurately, and efficiently complete HVAC system charging.

This machine utilizes the pressure difference principle, it is not equipped with the refrigerant pumping module.
