Lange Containment Systems LLC

Lange Containment Systems LLC, a small for-profit limited liability company based in Denver, Colorado, manufactures and sells snow pillow sensors and custom inflatable measurement devices to the U.S. Department of Agriculture's Natural Resources Conservation Service (NRCS) as a prime contractor on full-and-open purchase orders.

Lange operates exclusively as a prime contractor (100% of awards) with no sub-award footprint. The vendor competes almost entirely outside set-aside programs — six of nine awards carry no set-aside designation — though two recent orders (July 2025 and September 2024) were placed under Total Small Business set-asides. The company's capability portfolio centers on snow pillows, the inflatable hydrological sensors used at SNOTEL (Snow Telemetry) monitoring sites across the western United States to measure snow water equivalent for drought assessment, spring runoff forecasting, and water resource management. Product variants include 6-foot and 10-foot diameter Hypalon hexagonal and polypropylene round models, with standard and reinforced 60-mil construction, and custom outlet configurations.

Customer concentration is absolute: the Department of Agriculture's NRCS Western Region accounts for all nine awards and the full $436 thousand in combined potential value. Awards span the past four years with a cyclical pattern — four orders in 2022, one in 2023, one in 2024, and two in 2025 — suggesting annual or biennial procurement cycles for snow pillow replacement and expansion at regional SNOTEL networks. Named representative work includes a $107,185 order placed July 1, 2026 (two weeks ago) for snow pillow sensors to support Oregon water resource monitoring, a $65,221 purchase order from July 2025 for 20 units (10 Hypalon 6-foot hexagonal, 9 and 1 polypropylene 10-foot round) for Alaska and Idaho deployment, a $78,760 order from August 2022 for 60 reinforced Hypalon snow pillows supporting Colorado snow survey operations, and a $46,875 purchase from July 2023 for 15 units to the Colorado Snow Survey Program.

One award (the July 2026 order valued at $107,185) reaches ultimate completion within the next twenty-four months, representing the only recompete exposure in that window. Lange's primary NAICS categories are All Other Plastics Product Manufacturing (five awards) and Analytical Laboratory Instrument Manufacturing (three awards); PSC codes split between Plastics Fabricated Materials and Laboratory Equipment and Supplies, reflecting the vendor's dual posture as both a custom molded-rubber fabricator and an instrument supplier.
