Detailed Feature: Thermal Separation for Energy Saving
The cold to freezer door ensures effective thermal separation between temperature zones.
By combining rapid door cycles with airtight sealing, this door prevents warm air from entering the freezer zone or cold air from escaping, preserving consistent temperatures.
This thermal separation reduces energy consumption, prevents frost buildup, and maintains optimal storage conditions for perishable goods.
Installation Instructions
All measurements are made indoors and each value must be measured at at least three points:
H--the height of the doorway (the distance from the ground to the top of the doorway)
B--the width of the door opening (the distance from the left edge of the door opening to the right edge)
h--Above the doorway (the distance from the top of the doorway to the ceiling) is generally reserved 600mm
b1/b2--The lateral distance of at least 200mm (the distance from the corresponding edge of the door opening to the obstacle) is required to have 500mm reserved on the side of the motor:
When measuring H and B, take the maximum value as the final dimension
When measuring h b1 b2, take the smallest value as the final size
