Model AC Air Curtain
ADS-400
Model AC is HCR’s basic unit — Horizontal, Curvilinear, and Recirculatory. Its air stream produces counter-flow forces equal and opposite to the two-way flow-through forces caused by air temperature differences.

Door Features:
- Wide open environment while maintaining temperature
- Significantly reduces two-way air exchange
- Greatly diminishes air infiltration
- Mixes air at the interface between room air and the air curtain’s air stream
- For open doorways between cooler-to-cooler, cooler-to-ambient, and freezer-to-freezer
- Available in stainless and powder-coat finishes
- Can be used between two freezers without requiring any heat
