PP-R Pipe Products
Aquatherm Blue®: PP-R pipe for industrial applications
Aquatherm Blue® delivers durable, fusion-welded PPR piping engineered for heating, cooling, and industrial applications.
Aquatherm Blue® is a polypropylene (PP-R) piping system designed for hydronic, industrial, and data center cooling systems where corrosion resistance, performance consistency, and long service life are essential.
Proven performer
Long-life pipe system engineered for reliability for applications requiring performance beyond traditional metallics.

Designed to repel acids, bases, and reducing agents, and won’t corrode like metallic systems.

Optimal performance with leak-free joints, unlike ductile iron (DI) and PVC.

Superior longevity and reliable performance over steel, iron or copper alternatives.

Faster, easier, and more cost-effective to install than other pipe systems

Low thermal conductivity that improves energy efficiency.
Built for high-demand piping environments
Industrial process cooling
Corrosion-free for high-demand cooling circuits in manufacturing and processing environments.
Data center cooling loops
Reliable, fusion-welded PPR piping for stable chilled-water and condenser-water systems.

Beyond Concrete: The Advantages of HDPE Pipe in Modern Piping Solutions
In a world where comfort often breeds resistance to change, the emergence of high-density polyethylene (HDPE) in large-diameter piping systems is revolutionizing the industry. While reinforced concrete pipes (RCPs) have long been the norm, HDPE offers a plethora of benefits from installation to long-term performance. Let’s delve into why HDPE is becoming the preferred choice over RCP.
