1/4 inch connector for fast, reliable nitrogen interface - Quick connect to a standard nitrogen regulator outlet. After turning off the rinse tool, attach a standard 1/4 inch coolant hose to complete rinsing and soldering in seconds. Designed for HVAC maintenance - Built to meet the demands of rigorous HVAC servicing, delivering more consistent operation, reducing the risk of system failures, and improving overall efficiency and equipment longevity. Core functions and benefits - Facilitates smooth nitrogen penetration into pipes during rinsing and soldering. - Helps purge refrigerants and deposits from lines. - Prevents oxidation and related equipment failures. - Ensures clean, debris-free pipelines for reliable operation. 3-point position scale for precise control - Features an easy 3-point scale to switch quickly between rinse, solder, and shutdown settings. - Provides the correct nitrogen rate for each setting, enabling fast, accurate operation. Use scenarios - Pre-solder purge of copper refrigerant lines during HVAC installation or service to remove refrigerants and deposits before soldering. - Rinsing and cleaning HVAC pipelines after service to prevent contamination and oxidation. - System commissioning or leak testing to ensure lines are clean and properly purged with nitrogen.
