With over 10 years experience building automated A/C systems and a 50+ year reputation of building quality HVAC service tools, Ritchie Engineering knows what it takes for service technicians and shop owners to meet today’s tough service standards - A/C service centers that are quick and easy to operate while lowering A/C service costs. That’s why we designed the YELLOW JACKET® Refrigerant Management System (RMS) 37880, which offers many of the same features of the RMS 39800, but with SAE J2788 approval. With the press of one button, you get full cycle recover/recycle/evacuate/recharge to bring the vehicle back to factory spec. The other buttons give you the flexibility and efficiency for specific A/C services. Advantages of the RMS 37880 include oil injection for work savings, faster vacuum/charge, and an ABS plastic cabinet with rounded corners to prevent damage to cars.
