EZ-Roll Plus™ Black insulated copper tubing is the latest introduction from Great Lakes Copper LTD for line set, refrigeration and general HVAC applications. Proudly introducing EZ-Roll Plus™ Black, Great Lakes Copper LTD continues to bring forward new and innovative solutions to the challenges of tomorrow. Proving to be its most distinct characteristic, the durability of the black coating is its most significant advantage, providing exceptional tear-resistance wherever it is installed. Traditional elastomeric insulation often becomes torn or removed entirely when it comes into contact with sharp or rough contours, often requiring on-site repair and contributing to a loss of efficiency in the system. EZ-Roll Plus™ Black has an exterior coating that can handle installations through rough concrete access points, through wooden joists or other rough surface conditions. Eliminating tears avoids repairs and saves you time. The black coating also features UV and moisture-resistant qualities, securing against thermal losses and providing longevity when in direct contact with sunlight and UV rays. EZ-Roll Plus™ Black is available in standard line set configurations for residential or commercial air conditioning dual-line insulated ductless mini split options for split heating or cooling systems and available as single line insulated options for dedicated thermal or cooling applications.
