High-Torque Performance. Zero-Interruption Progress. Microtunneling demands extreme precision and massive bursts of power that can strain even the most robust site setups. An Ampd ESS provides the power buffer needed to handle the high-torque demands of a Tunnel Boring Machine (TBM) and slurry pumps.
Microtunneling demands absolute precision, but traditional diesel generators are often the weak link. Their mechanical systems aren't designed to react instantly to the sudden, high-torque surges required when a Tunnel Boring Machine (TBM) encounters changing soil densities.
The erratic load patterns of hydraulic pumps, slurry systems, and jacking stations cause traditional engines to ramp up and down constantly, leading to fuel waste and excessive wear. In tight urban environments, the resulting noise and exhaust can also lead to permit restrictions and community complaints.
Pairing your generator with an Ampd Battery Energy Storage System (ESS) creates a localized "microgrid" for your site. The ESS handles the massive current spikes required for TBM startup, allowing your generator to run only during its peak efficiency window or for just a few hours a day.
By utilizing an ESS to manage peak loads, operators can maintain continuous forward motion, slash fuel overheads, and significantly reduce the noise and emissions footprint of the project.
Power high-torque TBMs and slurry pumps with smaller, more efficient generators, reducing both rental and fuel expenses.
Achieve a near-silent site and zero local emissions, making it easier to secure permits for tunneling in densely populated areas.
An Ampd acts as a vital power buffer, ensuring consistent torque and preventing machine stalls during critical drives.
Microtunneling operations face more power surges and volatility than many realize. An Ampd provides the "muscle" for every stage of the drive:
Provides instant high-amp startup support to prevent voltage dips during initial torque-up.
Maintains smooth, reliable operation of high-pressure pumps without destabilizing the site power system.
Operates centrifuges and shakers efficiently, buffering the load to prevent generator "tripping"
Delivers high powerbursts for pipe lowering and soil removal without disrupting wider site power.
Keeps life-critical air filtration and communications online even during primary power outages.
