Copper
These seamless drawn tubes are specially designed for ACR installations. Presented in straight lengths to provide an easy installation and good service shape.
Insulation
The insulation of this product is made of NBR (Nitrile- Butadiene Rubber) as main row material for foaming and it becomes fully closed cells of flexible rubber insulation materials. Without any fiber ingredient, HCHO and CFCs which are harmful to the ozonosphere, hence this latter is considered environment friendly. This material does not contribute in fire propagation and does not emit toxic gases. Its high performance and low cost allowed rubber insultation to be widely used in various fields.
