Product Description
The DSZH-520 Refrigerant Recovery Unit is a high-performance HVAC tool designed for efficient recovery of refrigerants across a wide range of air conditioning and refrigeration systems. Built with an oil-free compressor and double cylinder design, it ensures fast, reliable, and contamination-free recovery operations.
This unit features one-key operation, making it simple and user-friendly for technicians, while the self-purge (self-clearing) function helps remove residual refrigerant, improving efficiency and reducing cross-contamination. Equipped with high-pressure protection and an embedded pressure gauge, the DSZH-520 ensures safe and controlled operation in demanding environments.
Its robust construction and strong recovery rates make it ideal for both field service and workshop applications.
