Reliable cooling for critical infrastructures. PP-RCT plastic pipes for liquid-cooled data centers.
Data centers are the backbone of our digital world. They house critical servers and IT equipment that require constant and efficient cooling. With increasing server density and rising power consumption, traditional air cooling is often no longer sufficient to effectively manage heat loads. Liquid cooling has proven to be a superior solution, providing unmatched thermal efficiency to maintain optimal operating conditions. Heat is the enemy of IT infrastructure. Even small temperature increases can significantly shorten equipment lifespans and lead to costly failures or downtime. Liquid cooling not only mitigates these risks but also improves energy efficiency, making it the ideal choice for modern data centers.

The ideal solution – POLYMELT PP-RCT piping systems for liquid cooling of data centers
POLYMELT pipes made of polypropylene random copolymer with elevated temperatures (PP-RCT) set new standards for liquid cooling systems in data centers. Outstanding consistent performance, reliability, and sustainability.
Advantages of PP-RCT pipes:

Korrosionsfrei: PP-RCT ist korrosionsresistent, widersteht Ablagerungen und vielen Chemikalien – sauberer, effizienter Betrieb über
Jahrzehnte.
Durability: With an expected service life of 50+ years, PP-RCT piping systems are designed for long-term use, reducing maintenance and replacement costs.
Lightweight: Up to 80% lighter than metal pipes, making them easier to transport and install.
Insulating properties: PP-RCT has a low R-value, reducing the need for additional insulation and reducing condensation.
Environmentally friendly: PP-RCT is fully recyclable, making it a sustainable choice for future-oriented data centers.
Why liquid cooling with POLYMELT MECHANICAL PP-RCT pipes?
Up to 3,467x more efficient at heat dissipation than air.
Supports higher server density. Reduces energy costs and optimizes data center operations.
Liquid cooling systems require less energy and are quieter than air-cooled alternatives.

The challenges of traditional piping materials
Not all piping systems are the same. Traditional materials such as steel, copper, and PVC have significant disadvantages and are less suitable for liquid-cooled data centers:
- Corrosion: Metal pipes such as steel and copper are susceptible to rust and deposits, resulting in contamination and potential failure.
- Condensation: The surface of metal pipes is particularly prone to condensation. Humidity increases, and hardware can be damaged.
- Complex installation: Welding and soldering processes produce fumes and potential fire hazards, making on-site installation more risky.
- Weight: Steel or copper pipes are difficult to transport and install. The labor required is significantly higher in terms of materials and labor compared to installing PP pipes.


Easy installation and maintenance – PP-RCT piping systems for liquid cooling of data centers
PP-RCT piping systems are designed for simple and efficient use and are suitable for new installations as well as replacements and retrofits. During operation, PP-RCT systems require minimal maintenance. This means greater security for servers and hardware and lower total cost of ownership.
Key advantages of installing PP-RCT pipes:

Connection technology: Pipe/pipe or pipe/fitting are combined into a single, homogeneous material – weak points and possible leaks are avoided.
No open flames: Unlike conventional welding, PP-R welding does not require open flames, reducing fire risks and allowing installation in an operating data center.
Prefabrication: PP-RCT components can be prefabricated off-site, minimizing downtime and accelerating project turnarounds.
Easy handling: Due to their low weight, PP-RCT pipe installations can be installed more safely and quickly, especially in tight spaces or overhead.
POLYMELT PP-RCT piping systems are very easy to install.
Replacing existing systems or connecting to existing systems.
Up to 80% lighter than steel pipes
PP welding technology enables faster and more secure connections than conventional welding or gluing.
Die nachhaltigere Wahl für Rechenzentren

Sustainability must play a central role in data centers, and PP-RCT piping systems are a step in the right direction.
Why are PP-RCT piping systems sustainable?
Low environmental impact: Requires minimal finishing, reducing the carbon footprint compared to metal alternatives.
Energy efficient: The material properties of PP-RCT are suitable for reducing energy consumption for cooling.
Fully recyclable: At the end of its life cycle, PP-RCT can be 100% reused.
By choosing PP-RCT, data centers can achieve LEED (Leadership in Energy and Environmental Design) certifications, contributing to a more sustainable future.
Why is sustainability so important in data centers?
Data centers consume 1% of the electricity produced worldwide – that’s approximately 300 billion kilowatt hours!
Environmentally friendly solutions like PP-RCT can help prevent this consumption from increasing unnecessarily.
