Sub-zero reliability, fast cycle times, and sealed controls that protect your temperature integrity. Built for high-traffic cold rooms, freezers, and pharmaceutical cold chain facilities where downtime is not an option.
Cold facilities punish conventional operators, heavy sliding doors, rapid forklift traffic, frost, washdowns, and relentless duty cycles. In pharmaceutical cold storage, the stakes are even higher: medical supplies and temperature-sensitive medicines rely on consistent access and stable temperature zones. That’s why GDI focuses on reliable motion, tight sealing behavior, and predictable performance in sub-zero conditions.
GDI started in large freezer environments where every extra second a door stays open means energy loss, frost issues, and operational delays. Traditional chain and sprocket systems can be powerful, but they demand alignment, ongoing maintenance, and protection from corrosion in extreme cold. Our approach focuses on controlled, repeatable movement that keeps the workflow moving while helping maintain the thermal envelope.
Upgrade existing cold storage doors without replacing the full door system, minimize downtime during changeover.
Faster upgrades
Built for extreme daily traffic in cold rooms and freezer bays where being down is not an option.
Extreme duty
Engineered for cold environments where standard operators struggle, keep operations moving in deep-freeze zones.
Sub-zero
Helps protect controls from washdowns, moisture, dust, and harsh facility conditions.
Protection
Smooth acceleration and soft stops reduce impact, vibration, and unnecessary stress on doors and hardware.
Gentle motion
Fast open/close cycles help reduce time-open exposure and keep forklifts and staff moving safely.
