" A variety of urethane panel doors showing powerful enclosing  "

Standard door – opening 800X1700 standard
Insulated doors using hard urethane foam as warming materials play a very important role in insulating low-temperature warehouses. With regard to doors whose temperature exchanges with the outside environment are very active, the degree of air tightness greatly influences refrigeration loads. Leehwa Polytech understands the importance of this and places top priority on the air tightness and insulation during the production of doors.

We have ensured that refrigerator doors are not subject to
damageas a result of freezing by installing hot-wire heaters.

This product is installed in the upper part of doors of stores, restaurants, banks, shopping
malls and cold storage areas that people frequently visit in order to maintain room
temperature by generating air membranes generating through
the use of rotating fans. This product
also can maintain a comfortable atmosphere
by preventing the occurrence of dust
or insects, such as mosquitoes, botflies and moths.
 
Heat insulation
Blocks crosswind
Prevents dust from coming in
Blocks odor
Keep insects out
 
Applies 2nd powder coating of tempered glass
Introduction of Two motors ensures low-noise
Great out-structure distributes equal wind velocity
Small size and light weight allow for easy installation and repairs
A long safe commutation interval distributes equal wind velocity and great linearity


Energy waste caused by the opening and closing
of doors of rooms at worksites which people
frequently visit, such as factories, cold storage
areas and shops is reduced, and the occurrence
of wind, noise, dust and insects is prevented.
Thus energy savings are created and a pleasant
and comfortable working environment is
maintained. In addition, working efficiency and
safety management can be greatly improved through the free movement of people and vehicles.
 

1. Air from outside is blocked, indoor warming and cooling capacities are improved and energy and
    electricity can be saved.

2. Superior windproof, soundproof, dustproof and mothproof qualities can maintain good working
    conditions and help quality management.

3. Transparency and flexibility make rooms bright and guarantee free and safe passage of people and vehicles.

4. Strip Doors can be easily installed or disassembled, enabling savings in time and labor.

5. Polluted parts can be easily cleaned with water and it is easy to manage and maintain Strip Doors,
    so they can be installed semi-permanently.

6. Cheap installation costs can create various remarkable effects, so investments can be recouped
    in a short period of time.
