Heavy Duty Commercial Doors and Solutions

Commercial cold storage buildings typically use prehung swing doors or sliding doors for walk-in coolers and freezers. Swing doors suit standard-access openings, while sliding doors are preferred for high-traffic or forklift-access applications. Frame options include standard, plug, and heated jamb configurations to prevent frost, condensation, and energy loss.

A prehung walk-in cooler door arrives pre-assembled with its frame — either a standard frame or plug frame — and is designed as a true drop-in replacement. No on-site fabrication is required. You simply mount the unit in the existing opening, which significantly reduces installation time and labor costs.

ELT Custom Coolers stocks swing doors in widths from 30" to 60" and heights of 76" to 84". Sliding doors range from 36"x78" up to 12'x12'. With 65 cooler and 51 freezer swing door SKUs plus 18 cooler and 7 freezer sliding door SKUs, virtually every standard commercial opening is covered. Custom sizes are also available.

A heated jamb or heated frame is an electric resistance element embedded in the door frame that prevents frost and ice buildup at the door opening. This is critical for walk-in freezer applications where temperature differentials cause door-stick, condensation, and ice accumulation. ELT offers heated frame options on select swing and sliding freezer door models.

A strip curtain is a secondary PVC barrier hung in the doorway that maintains temperature separation when the door is open. During high-traffic periods, a strip curtain like the Kason 402 Easimount can reduce compressor run-time by 20–40%, cut ice buildup on freezer frames, and support food-safety temperature compliance without restricting access.
