REHAU RAUGEO™ Geothermal Ground Loop Wins Alternative Energy Product Innovation Award


CIPHEX West 2014 Competition Recognizes Innovative New Products

REHAU RAUGEO™ PEXa double U-bend ground loop heat exchanger was recognized as the Alternative Energy category winner in the CIPHEX West 2014 New Product Gallery / Most Innovative Product Competition. The competition was held at BMO Centre, Stampede Park on November 5-6 in Calgary, AB.

An independent jury selected the winning products, each of which were required to meet at least two of the following criteria:

- Promotes sustainability
- Uses new or existing materials in an innovative manner
- Makes the workload easier (for sales staff, designers or installers)
- Has a new look and design which improves its functions
- Promotes a safe environment
- Has a lower price due to the innovation

The RAUGEO ground loop heat exchanger is a high-efficiency source for heating and cooling, offering a unique system design, durable PEXa pipe and easily-accessible balancing manifolds that allow for balancing and control of the system.

PEXa Pipe Offers Installation, Economy, Long-term Performance Advantages Over Traditional HDPE Geothermal Systems

PEXa offers elevated temperature strength, chemical and abrasion resistance as well as resistance to slow crack growth; some of the most important criteria for ground loop heat exchangers. Its superior flexibility – with a bend radius of 5 times the pipe OD as compared to 25 times the pipe OD for HDPE – makes PEXa piping easy to handle and install even at cold temperatures.

In addition, the RAUGEO PEXa double U-bend design increases borehole thermal conductivity allowing for a more compact borehole field. This reduces drilling and grouting costs and enables faster installation. 

PEXa piping's toughness allows for the use of native backfill, which reduces installation time and costs and provides superior thermal conductivity for geothermal applications. 

Connections are made using ASTM F2080 cold-expansion compression-sleeve fittings that install securely and quickly without heat or electricity in any weather conditions. The system is ready for pressure testing immediately, resulting in further reduction in installation time and costs.

U-bends are offered in prefabricated 1 and 1 1/4 in. CTS and are delivered to the jobsite in continuous coils of up to 520 ft. 

Energy Savings of Up to 70% Over Traditional Heating

As part of a geothermal heat pump system, CSA-approved RAUGEO offers energy savings of up to 70% when compared to traditional heating methods. A typical residential system reduces CO2 emissions by more than 200 tons over a 20-year period.
