Case Study: Greenland Contractors achieves dependable Arctic access control at Thule Air Base with acre security

Entro Combats Extreme Weather at Arctic Airbase

Greenland Contractors, which manages daily operations and maintenance at Thule Air Base, faced extreme Arctic conditions—regular lows near -60°F and recorded winds up to 207 mph—that required outdoor access control hardware capable of operating reliably in sub-zero temperatures and resisting high static electricity. To meet this challenge they selected acre security and its outdoor access control solution to provide robust card readers and system functionality suited to the harsh environment.

acre security implemented a resilient access control system with anti‑passback, remote door unlocking from the hilltop central control station, and a booking function for the popular solarium used during the polar night. The deployment delivered dependable operation in extreme weather, prevented personnel from being stranded outside in sub‑zero conditions, and supported day‑to‑day facility management for Greenland Contractors, ensuring uninterrupted access and safer operations at Thule Air Base.
