[Example] Air Conditioning and Refrigerant Piping Nitrogen Purging Work

Prevent the formation of scale inside the piping! We will reduce the causes of air conditioning equipment failures.

We would like to introduce a case study of nitrogen purging work for air conditioning and refrigerant piping using the high-pressure nitrogen-enriched gas generator 'HND-4640B' and the nitrogen gas generator for purging 'SLF-5000-1P'. When heating copper pipes during soldering work, scale can form on the pipes, so performing nitrogen purging can prevent the formation of that scale. By connecting a nitrogen gas generator that produces high concentration nitrogen gas from the low-pressure port (0.IIIPa) of this device, and using that high concentration (over 98%) nitrogen gas as purging gas during soldering work, we can prevent the formation of scale inside the piping and reduce the causes of equipment failure in air conditioning systems. We have provided the work procedures in a PDF document. 【Specifications for airtightness testing equipment】 ■ High-pressure nitrogen-enriched gas generator - Discharge pressure: 4.5MPa - Nitrogen concentration: 85% or higher *For more details, please refer to the PDF document or feel free to contact us.
