Geothermal Double U-Bend (Large Body), PE100 for High-Flow Probes
Product Overview
The PE100 “Large Body” Double U-Bend is engineered for performance-driven Ground Source Heat Pump (GSHP) installations. While serving the same fundamental purpose as a compact U-bend—creating a 180° return for the geothermal probe—this model prioritizes hydraulic efficiency. Its “large body” features wider, gentler radius bends. This design significantly reduces pressure drop (head loss) and turbulence as the heat transfer fluid circulates through the bottom of the loop. The direct benefit is lower energy consumption from the circulation pump, leading to improved system efficiency (COP) and reduced long-term operational costs. Manufactured from premium PE100, it ensures a permanent, leak-proof socket fusion connection deep underground, offering the same 50+ year reliability expected from geothermal systems. It is the ideal choice for projects where borehole diameter is sufficient and maximizing energy efficiency is a key design criterion.
Key Features
- Superior Hydraulic Performance: The wide-radius design is the primary advantage, minimizing frictional losses and allowing the circulation pump to operate more efficiently, saving energy over the system’s lifespan.
- Permanent Leak-Proof Connection: Equipped with DIN standard spigot ends for socket fusion welding, it creates a fully monolithic joint that is as strong as the pipe itself, eliminating underground leak risks.
- Enhanced System Efficiency: By lowering the overall system head loss, this fitting contributes directly to a higher Coefficient of Performance (COP) for the entire heat pump system.
- Robust PE100 Construction: Offers outstanding resistance to stress cracking, abrasion, and chemical attack from soil and heat transfer fluids, ensuring maximum durability.
- Improved Borehole Centering: The larger profile can help to better center the U-pipes within the borehole, promoting a more uniform grout envelope for consistent thermal transfer.
Available Types / Connection Methods
This fitting has two spigot outlets for socket fusion connection and is available in standard geothermal pipe sizes: DN25 and DN32.
Applications
Specifically designed for the fabrication of vertical borehole geothermal probes, it is the preferred choice for:
- Commercial and large-scale residential GSHP projects.
- Installations where maximizing energy efficiency and reducing lifecycle cost are paramount.
- Boreholes with sufficient diameter to easily accommodate the larger fitting profile.
