冷库门设计
冷库门门扇均采用优质的材料、全封闭整体框架结构，硬质聚氨酯发泡，门扇内外覆不锈钢，并可根据用户的要求选用，如：涂漆彩钢板、镀锌板或铝板等。门扇的开启与关闭采用手动推拉平移式，顶部轨道采用曲线形式，当门关闭到位时，门扇自动压紧地坪及门框。保证了良好的密封性能。开启时，门扇同步离开门框，并上升，减少了密封橡胶条与门框、地坪的摩擦。门扇四周内有低电压电加热器，防止在低温下门扇与门框的冻结。该门还设有库内脱险装置，当工作人员误锁在库内时，只要拉动内脱险环，并拉动开门内手柄，门就能顺利打开。
特点：该手动移门具有结构合理，不吸潮、不生锈、不变形、重量轻、隔热性能好、占地少等特点，是当今先进、美观、理想的冷藏库门。

Cold door design
The cold library door fans are all *de of high-quality *terials, fully enclosed overall frame structures, rigid polyurethane foaming, stainless steel inside and outside the door fan, and can be selected according to user requirements, such as: painted colored steel plate, galvanized plate or aluminum plate. The opening and closing of the door fan are *nual Push-Pull translation, and the top track is curved. When the door is closed in place, the door fan auto*tically presses the floor and the door frame. Ensure good sealing perfor*nce. When opened, the door fan le*es the door frame synchronously and rises, reducing the friction between the sealed rubber bar and the door frame and the floor. There is a low electric piezoelectric heater around the door fan to prevent the door fan and the door frame from freezing at low temperatures. The door is also equipped with an internal escape device. When the staff is mistakenly locked in the library, the door can be opened *oothly as long as the inner escape ring is pulled and the handle is pulled.
Features: The *nual sliding door has the characteristics of reasonable structure, no moisture absorption, no Rust, no defor*tion, light weight, good ther*l insulation perfor*nce, and s*ll area. It is an advanced, beautiful and ideal refrigerator door.
