What is XLPE insulation?
XLPE (Crosslinked Polyethylene) is a thermoset insulation material renowned for its exceptional durability and performance. Created by cross-linking polymer chains, it offers superior thermal stability, excellent moisture and chemical resistance, and high mechanical strength compared to standard polyethylene, making it the premium choice for protecting critical VRF copper joints from energy loss and condensation.
Why is XLPE insulation important for VRF systems?
VRF systems are highly efficient but require precise refrigerant temperatures. XLPE insulation is vital as it minimizes unwanted heat gain or loss in piping, maintains system efficiency, and, crucially, prevents condensation that leads to corrosion, mold, and water damage. Its durability ensures this protection lasts for the system's entire lifecycle.
What is the temperature range of DA Series XLPE insulation?
Our DA Series XLPE insulation is engineered to perform reliably in a wide temperature range from -40°C to +90°C. This ensures optimal thermal protection and physical integrity in both extreme winter conditions and high-temperature summer operations, guaranteeing consistent VRF system performance in any climate or environment.
Is the XLPE insulation fire‑resistant?
Yes, absolutely. Our insulation is specifically formulated to be Fire Retardant (FR) Grade. It is designed to inhibit the spread of flame, produce low smoke, and self-extinguish, thereby significantly enhancing the overall fire safety profile of the building's HVAC installation and complying with stringent safety standards.
How does XLPE insulation prevent sweating?
Sweating occurs when warm, humid air contacts cold piping. Our XLPE insulation features a closed-cell structure that acts as a superior vapor barrier, drastically reducing water vapor transmission. This, combined with its low thermal conductivity, keeps the outer surface temperature above the dew point, effectively eliminating condensation and its associated problems.
Is the insulation UV‑protected?
Yes, our DA Series insulation is UV-stabilized. This critical additive protects the material from degradation caused by prolonged exposure to sunlight, preventing cracking, loss of elasticity, and thermal performance decline. This makes it perfectly suitable for outdoor sections of VRF piping without requiring an additional protective jacket.
What certifications does the DA Series insulation have?
Our product is RoHS (Restriction of Hazardous Substances) and CE compliant. These certifications verify that the material is free from restricted hazardous materials and meets European health, safety, and environmental protection standards, ensuring it is safe for use and acceptable in regulated global markets.
How do I install the DA Series insulated joints?
Installation is designed for efficiency. The insulation is pre-slit and pre-shaped. Simply open the slit, wrap it snugly around the cleaned copper joint, ensure a tight seal at all seams, and then secure it permanently with compatible HVAC-grade adhesive tape to form a continuous, unbroken insulation layer.
Can I get custom sizes and shapes?
As a top-tier manufacturer, we specialize in customized solutions. We can produce XLPE insulation in any precise size, thickness, or complex shape to fit unique Y-joint configurations or specific project requirements, using our specialised dies and moulds to ensure a perfect and professional fit every time.
What is the lifespan of XLPE insulation?
Our high-grade XLPE insulation is engineered for exceptional longevity and is designed to last the entire service life of the VRF system itself. When installed correctly under standard operating conditions, its performance and protective integrity typically remain uncompromised for decades, often exceeding 20-25 years. This extended lifespan is a direct result of its cross-linked structure, which provides outstanding resistance to environmental aging, thermal stress, and physical wear, ensuring long-term reliability and delivering superior lifecycle value for your investment.
