Product Overview

The PE100 “Large Body” Single U-Bend is a high-performance fitting designed to optimize the efficiency of single-loop Ground Source Heat Pump (GSHP) systems. It serves the essential function of creating the 180° return at the base of a geothermal borehole but with a key advantage: a focus on hydraulic performance. The “large body” incorporates a wider, gentler bending radius compared to standard compact fittings. This intelligent design significantly minimizes fluid friction and turbulence, resulting in a lower pressure drop across the loop. For the project owner, this translates directly into reduced energy consumption for the circulation pump, a higher system Coefficient of Performance (COP), and lower operating costs over the building’s lifetime. Manufactured from top-tier PE100 resin, its DIN spigot ends are fused to the pipe, guaranteeing a permanent, leak-proof system that will last for over 50 years underground. It is the premier choice for projects where maximizing energy efficiency is a priority.

Key Features

Optimized for Energy Efficiency: The wide-radius curve is the core feature, engineered specifically to reduce head loss. This allows for smaller pump specification or lower pump speed, saving significant energy.
Permanent, Monolithic Connection: Socket fusion welding creates a joint as strong and reliable as the pipe itself, completely eliminating the risk of leaks, which is critical for buried infrastructure.
Boosts System COP: By improving the hydraulic efficiency of the ground loop, this fitting makes a measurable contribution to the overall energy efficiency (COP/EER) of the entire heat pump system.
Heavy-Duty PE100 Construction: Guarantees extreme durability, with superior resistance to slow crack growth, abrasion, and chemicals, ensuring long-term integrity in any soil condition.
Enhanced Grout Flow: The larger external profile helps maintain a consistent annular space around the pipes, promoting a uniform grout envelope for optimal heat transfer.

Available Types / Connection Methods

This fitting is built for a single pipe loop and features two spigot outlets for DIN-standard socket fusion. It is available in DN25 and DN32 sizes.

Applications

Ideal for fabricating high-efficiency single-loop geothermal probes in:

Energy-conscious residential and commercial buildings.
Projects aiming for green building certifications (e.g., LEED, BREEAM).
Installations with boreholes of sufficient diameter to accommodate the fitting.

Standards & Quality

Produced in our ISO 9001 certified facility from PE100 raw material compliant with ISO 4427. Every fitting is dimensionally checked to meet DIN standards for perfect fusion compatibility.
