Suitability for Negative Temperature and Freezing Room Doors
The BOB-12865 Aluminum Door Leaf Profile is designed for cold room doors operating in negative temperature ranges. It is particularly suitable for:
- Standard negative temperature cold rooms
- Lower negative temperature applications
- Freezing rooms, when used with an appropriate door leaf system
In freezing room applications, double-gasket door leaf systems are generally preferred to achieve maximum airtightness and insulation. However, double-gasket systems increase both production complexity and cost. BOB-12865 provides an alternative solution by enabling the production of single-gasket door leaves that still deliver sufficient insulation performance for many freezing room applications.
This makes BOB-12865 a more economical door leaf profile, especially in projects where full double-gasket systems are not strictly required.
Cold Room Door Leaf Manufacturing with BOB-12865
The BOB-12865 Aluminum Door Leaf Profile is fully compatible with the polyurethane injection manufacturing system, which is widely used in industrial cold room door production.
The production process includes the following stages:
- Aluminum Door Leaf Frame Assembly
The aluminum profiles are cut precisely according to door dimensions and assembled to form a rigid door leaf frame.
- Thermal Isolation Between Aluminum and Sheet Metal
To prevent thermal bridging between the aluminum profile and the metal sheet, BOB-P571 – Cold Room Door Leaf U Gasket is used.
📌 Important Technical Detail:
In this system, BOB-P66 is not used. The geometry and performance targets of the BOB-12865 system are specifically designed to work only with BOB-P571, ensuring optimal insulation and cost efficiency.
- Polyurethane Injection
High-density polyurethane foam is injected into the door leaf structure. The polyurethane:
- Fills all internal cavities homogeneously
- Provides reliable thermal insulation
- Increases the rigidity and strength of the door leaf
This process results in a durable, monoblock door leaf suitable for negative temperature operation.
Single-Gasket Door Leaf System for Freezing Rooms
In many freezing room applications, door leaves are traditionally produced using double-gasket systems. These systems are commonly manufactured using:
- BOB-30169 Aluminum Door Leaf Profile
- BOB-10074 PVC Strip
Together, these components create a double-gasket door leaf structure, offering maximum sealing performance.
However, BOB-12865 allows for the production of a single-gasket door leaf system, which provides:
- Lower production cost
- Reduced material usage
- Shorter manufacturing time
This makes BOB-12865 a highly attractive option for freezing rooms where cost-effective solutions are required without compromising essential insulation performance.
Application Areas
The BOB-12865 Aluminum Door Leaf Profile can be used to manufacture:
- Cold room hinged door leaf
- Cold room sliding door leaf
- Cold room automatic sliding door leaf
- Cold room monorail sliding door leaf
These door leaves are suitable for negative temperature cold rooms and, with the appropriate system configuration, freezing room applications.
Advantages of Anodized Aluminum Construction
BOB-12865 is manufactured from anodized aluminum, offering several key benefits:
- High resistance to corrosion
- Long service life in humid and low-temperature environments
- Hygienic and easy-to-clean surfaces
- Professional and aesthetic appearance
These properties are especially important for cold rooms used in the food, logistics, and pharmaceutical industries.
Conclusion
The BOB-12865 Aluminum Door Leaf Profile is a practical and economical solution designed for negative temperature cold room doors and suitable for freezing room applications with the correct system configuration. By enabling single-gasket door leaf production, it offers a cost-effective alternative to traditional double-gasket systems produced with BOB-30169 and BOB-10074.
With polyurethane injection compatibility, BOB-P571 thermal isolation, and a durable anodized aluminum structure, BOB-12865 delivers reliable performance, energy efficiency, and long-term durability.
