Cold door
Cold doors are systems designed to maintain controlled temperatures in refrigeration and freezing chambers. Their main function is to prevent heat transfer between the exterior and interior, helping to preserve internal temperature and reduce energy costs. They are vital in sectors such as the food, pharmaceutical, and logistics industries, as they facilitate access without compromising the integrity of the cold environment and prevent the entry of warm, contaminating air.
DESCRIPTION OF MATERIALS
- Polyurethane: Provides excellent thermal insulation, lightweight, and low conductivity.
- Expanded polyethylene: A more economical option, although less efficient in terms of insulation.
- Rock wool: Offers good insulation and fire resistance, although it may be heavier.
OUTER CASING
- Galvanized steel: Resistant to corrosion and wear, ideal for industrial environments. Its zinc coating extends its lifespan.
- Stainless steel: Very hygienic and easy to clean, perfect for the food industry and humid environments.
- Aluminum: Lightweight and corrosion-resistant, suitable where reduced weight is required.
SEALING JOINTS:
- Rubber joints: Ensure a tight seal, preventing cold air leaks and warm air entry. They are flexible and resistant to extreme temperatures.
ACCESSORIES:
- Hinges and handles: Generally made of stainless or galvanized steel for durability, designed for frequent use.
- Locks: Vary according to security needs and are also made of corrosion-resistant materials.
GLAZING (IF APPLICABLE):
- Double or triple glazing: Used in cold doors with windows, made of low thermal conductivity glass, often with a special coating to enhance insulation.
