Controlled Atmosphere Sliding Doors
Precision-engineered gas-tight sealing systems for specialized agricultural hubs and long-term fruit preservation facilities.
General Description
SITC SMART Controlled Atmosphere (CA) sliding doors are specifically developed and engineered to meet the stringent sealing requirements of specialized agricultural hubs and long-term fruit preservation facilities. Featuring a high-performance, gas-tight sealing system, these doors provide a 100% airtight and gas-impermeable barrier.
This absolute seal allows for the precise regulation of internal oxygen and nitrogen levels, ensuring crops, vegetables, and fresh fruits remain perfectly preserved for extended durations without losing raw weight or product freshness.

Eccentric Compression Technology
Mechanical Tightness
Equipped with an eccentric stainless steel shaft. Upon full closure, the mechanism mechanically compresses the door leaf aggressively against the outer framing lines.
Dual Gasket Arrays
Combined with advanced closed-cell foam gaskets, this high compression force blocks atmosphere migration pathways entirely.
Gas-Tight Inspection Hatch
Seamlessly embedded hermetic inspection window allows for product sampling without breaking the internal atmosphere.
