Product Description
The POLYGON PEXB Capillary Pipe is a revolutionary product in the field of radiant surface heating and cooling. Its core innovation lies in its fine diameter (e.g., as small as 7.2mm OD) and exceptional flexibility, which allows for much closer spacing during installation. This creates a dense network of pipes that delivers even, radiant heat across floors, walls, or ceilings with minimal temperature variation ("no cold spots"). The pipe is constructed from high-quality PEX-B material, which provides inherent resistance to high temperatures , chlorine, and scaling. Its thin and lightweight profile minimizes the overall installation height, preserving ceiling space and simplifying integration with various decorative finishes. The system heats up rapidly due to the large effective radiation area and closer proximity to the surface, allowing for lower supply water temperatures, which translates directly into higher energy savings and improved system longevity by reducing limescale formation.

Performance Advantage
Superior High-Temperature & Impact Resistance
Offers better performance than standard PE-RT, reliably operating in high-temperature environments up to 95°C with excellent impact resistance.
Enhanced Comfort
The fine diameter allows for smaller, more uniform spacing. This creates balanced, dense radiant heat with minimal floor temperature difference, resulting in superior underfoot comfort.
Space-Saving Design
Thin, lightweight, and flexible, it requires minimal installation height, saving space and allowing for easy installation on floors, walls, and ceilings.
High Efficiency & Energy Saving
The close pipe spacing and proximity to the surface enable rapid heat-up. It operates at lower supply water temperatures compared to traditional systems, significantly improving energy efficiency.
Low Scaling Tendency
The lower operating water temperature required by the system inherently reduces the rate of limescale formation within the pipes, promoting long-term performance and reducing maintenance.
Applicable Scenarios
- Low-Temperature Floor/Radiant Heating Systems: Primary application for residential and commercial spaces.
- Low-Temperature Radiator Heating: Compatible with modern low-temperature radiator systems.
- High-Temperature Radiator Heating: Can be utilized in systems requiring higher supply temperatures.
- Radiant Surface Heating/Cooling: Installation in floors, ceilings, and walls for both heating and cooling purposes.
- Thermoactive Building Systems (TABS): Integration into concrete slabs for core heating and cooling in modern buildings.
