No Freeze-up on Vent Port Flaps
Keil Refrigeration Hardware, Lakewood, NJ, has introduced a new narrow profile vent port, which uses a specialized heating technology — Reliable Resistor Heating — to prevent the vent port flaps from freezing. This compact and energy-efficient vent port makes it easier for operators to open and close walk-in cooler and freezer doors. This durable Horizontal Vent Port for door jamb applications is both economical and energy efficient, and reduces the effort required to open refrigerator doors, sources report. Its narrow profile permits mounting in the door jamb above door. Silicone flaps equalize atmosphere pressure in walk-in coolers and freezers. The vent port's energy-efficient design only consumes 9W of power vs. 20-23W for competitive models

The flap's housing is constructed of rugged grey ABS plastic, UL flame retardant and rated 94-5V. A red indicator light warns if unit stops functioning. Two-part construction permits use on door widths from 3-5/8-in. to 4-1/4-in.
