For Supermarket freezer, large clear view and high energy effiency are very important. Glass door is the key point to achieve this goal.
An exellent glass door has a superior insulating glass,anti-fog film and special heating system to keep temperature while giving super clear view with a high energy effiency.
Glass door key point 1—insulating
Super clear view based on IGU ‘s super insulteing performance. Compared various options, we choose warm-edge spacer to achieve. Extruded as a high-quality silicone warm-edge spacer with integrally incorporated desiccant, Super Spacer Premium Plus Enhanced features a flexible matrix that works together with a vapor barrier and secondary sealant to keep moisture out and argon gas in.
Features:
Pressure-sensitive acrylic adhesive
Multilayer vapor barrier
High desiccant content
Superior silicone foam insulation
Low thermal conductivity
Substantially reduced perimeter condensation
Excellent UV resistance and temperature performance
Superior argon gas retention
Enhanced environmental comfort
Excellent durability for sustainable performance
All those design guarantee there is no dew and less cold air escape throw IG, which guarantees super clear view and energy saving.
Glass door key point—2 Anti-fog film and heating system
To give a large clear view, except for using Super Sapcer to keep no fog in the internal of IG unit (as mentioned ), the second key factor is to keep there is no fog on out surface of glass door. To achieve this, we use superior quality anti-fog film, meanwhile heating the glass and door frame.
When operating, the temperature difference is quite big between cabinet inside and outside.
We keep glass door out surface clear throw heating the outer glass, keeping its temperature at about18°C~25°C, water in air will not condense on.
But for glass door inner surface , this method waste energy and does not really work. Door’s inner surface is usually at same low temperature with cabinet working temperature, and when door opend, it facing an instant temperature differenc, an exellent anti-fog film will be an usful choice. We choose anti-fog PET Film from America which guarantee us an always clear view under all different conditions.
Films provide permanent anti-fog solutions, superior abrasion resistance, exceptional clarity and consistency. These films prevent fogging under all extreme temperature and humidity conditions, even after repeated cleaning or water immersion and are not affected by ammonia, alcohols, commercial glass cleaners, detergents or brief exposure to most industrial solvents such as acetone, toluene or trichloroethylene.
All those choices and design on details guarantee there is no fog on glass and frame, which finnally lead to a wide and super clear view to provide your customer a happy shopping experience.
