The "High Insulation Tube (Double-layer Insulation Type)" is a low-cost, flame-retardant coated copper pipe for refrigerants, which is more economical than the 20mm thick insulation type. Its insulation performance improves by approximately 15% compared to "NT-P23JN" when the outside temperature is 30°C. It enhances workability in narrow spaces and is suitable for concealed piping and condensation measures in whole-house air conditioning systems by house manufacturers. 【Features】 ■ Solves condensation issues in concealed piping for high insulation ■ Lower cost than the 20mm thick insulation type ■ Improved workability in narrow spaces ■ Approximately 15% better insulation performance than NT-P23JN at an outside temperature of 30°C ■ Insulates the liquid line side as well, making it suitable for condensation measures with air insulation effects *For more details, please refer to the PDF document or feel free to contact us.
