Application
The Danfoss TGES 20 TXV is ideally suited for commercial refrigeration equipment such as walk-in coolers and freezers, display cases, and cold storage systems using R404A or R507 refrigerant. The externally equalized design ensures accurate superheat control even when evaporator pressure drop is significant, making it the preferred choice for longer or distributed evaporator circuits. The 667 PSI MOP rating provides reliable compressor protection during high-load or startup conditions.
