Combisteel Upright Glass Door Cooler-FAQs
What are the benefits of a glass door cooler?
Glass doors allow you to see contents without opening the door, reducing cold air loss, saving energy, and helping you manage inventory quickly.
Why is there condensation (sweating) on the glass?
Condensation forms when warm, humid air hits the cold glass surface. This is common in humid environments. Ensuring the door seals are tight and the room is well-ventilated can help.
How do I prevent the glass door from fogging up?
Ensure the door seal is intact and clean.
Avoid placing the cooler in extremely humid areas.
Use a room dehumidifier or improve ventilation to reduce ambient moisture.
Don’t leave the door open for extended periods.
How do I clean the glass door?
Use a soft cloth and a mild, non-abrasive glass cleaner. Avoid harsh chemicals or abrasive pads that can damage the glass or seals.
Is a glass door less efficient than a solid door?
Modern glass door coolers are designed with energy-efficient, insulated glass. While a solid door may have slightly better insulation, the ability to see inside without opening the door often offsets any efficiency loss.
What is the ideal temperature setting?
For most food and beverage storage, the recommended temperature is between 2°C and 5°C (36°F and 41°F). Always refer to the manual for specific guidance.
Why does the exterior feel warm?
It is normal for the sides or front of the cooler to feel warm. This is where the condenser releases heat from the inside to the outside environment.
How long will the cooler last?
With proper maintenance, a commercial glass door cooler can have an average lifespan of 10-15 years. Regular cleaning and timely repairs are key to longevity.
