When it comes to walk-in cooler and freezer performance, much of the focus is on compressors, fans, and insulation — but one of the most critical components is also one of the simplest: the door gasket.
A door gasket may look like a basic rubber seal, but it plays a major role in your system’s efficiency, temperature control, and long-term durability. At ReFridge, we stock a wide range of replacement gaskets — and we know exactly how important they are.
How Gaskets Work
Walk-in cooler and freezer gaskets work through compression and insulation:
- Compression Seal: When the door closes, the gasket compresses tightly against the frame, closing any gaps where air could leak in or out.
- Insulation Barrier: The gasket material acts as a thermal barrier, helping prevent heat transfer around the door edge.
This double-duty function keeps your cooler or freezer running efficiently and protects your perishable goods from temperature swings and humidity.
Why a Good Gasket Matters
A worn-out or damaged gasket can have major consequences. Here’s what a bad gasket allows:
- Air Leaks: Letting warm air in forces your system to work harder to maintain temperature.
- Frost Build-Up: Moisture entering the unit leads to ice forming on coils and walls.
- Increased Energy Use: The harder your system works, the higher your utility bills.
- Product Loss: Fluctuating temperatures can ruin food or inventory.
Signs Your Gasket Needs Replacing
- Visible cracks, tears, or warping
- The door won’t stay fully closed or sealed
- Cold air feels like it’s leaking around the edges
- Increased frost, moisture, or temperature swings inside
- Higher energy bills with no other explanation
