High-Flow CNG Letdown & Stepdown Unit — Up to 250,000 SCFH
Maximum-capacity pressure reduction for the most demanding energy operations
The H250 is Broadwind's flagship high-flow CNG pressure reduction system — the most powerful stepdown unit in the product line. Engineered for the largest-scale CNG decompression and gas letdown operations, the H250 delivers unmatched flow capacity for applications where maximum throughput and reliability are non-negotiable.
With inlet pressures up to 4,900 PSI and flow rates reaching 350 MSCFH, the H250 handles the most demanding pressure stepdown requirements in the industry. Compressed Natural Gas stored at extreme pressures in tube trailers and storage vessels is precisely reduced to the delivery pressure required by large-scale downstream operations — from multi-spread frac operations to utility-grade power generation facilities.
At high flow volumes, the Joule-Thompson effect during pressure reduction becomes even more critical to manage. The rapid cooling that occurs during large-volume CNG letdown can freeze instruments, regulators, and piping if not properly addressed. The H250 is specifically engineered to handle these thermal challenges at scale, with robust heat management systems that maintain reliable operation across the full operating temperature range of -40°F to 120°F.
The H250 is the system of choice for high-volume virtual pipeline deployments. When large industrial consumers, frac operations, or power generation facilities need natural gas delivery outside of pipeline reach, the H250 stepdown unit provides the throughput capacity to match demand. Its ability to decompress CNG at rates up to 350 MSCFH makes it capable of serving operations that would traditionally require dedicated pipeline infrastructure.
Multi-stage safety architecture with pressure relief devices at every stepdown stage. Designed for continuous, unattended CNG letdown operations with minimal oversight.
Advanced PLC-based control of all safety and process systems. Intuitive HMI screens for set point management, alarm controls, and real-time monitoring of high-volume pressure stepdown.
Fully self-contained, trailer-mounted for rapid mobilization to any site. Equally suited for permanent high-flow installations and temporary CNG decompression deployments.
Full cellular connectivity for remote diagnostics, real-time data streaming, and 24/7 performance monitoring of the high-flow stepdown unit from any location.
Integrated power systems for fully autonomous operation at remote sites. No external power required to maintain continuous high-volume CNG letdown service.
Industry-leading 350 MSCFH capacity handles the highest-demand applications. Built for simultaneous service to multiple end users or large single-point consumers.
High-volume CNG stepdown for simultaneous dual-spread frac completions. Delivers the massive, consistent flow rates needed to fuel multiple frac spreads at once.
