Detailed Description

1. Product Overview

Cold‑storage sliding doors are specialized side‑sliding insulated doors designed for cold‑chain warehouses, available in single‑leaf and double‑leaf configurations. They feature polyurethane foam panels with no thermal bridges, paired with multi‑seal systems that withstand low temperatures and a recessed compression‑seal design. Standard models include electrically heated door frames to prevent freezing. These doors can be operated manually or electrically, accommodate large opening dimensions, and are well suited to frequent forklift traffic. They deliver excellent insulation and cold‑retention performance, while offering superior corrosion resistance and durability, making them ideal for use in freezers, food processing facilities, and pharmaceutical cold‑storage applications.

3. Technical Specifications of Cold Storage Doors

Parameter Item	Standard specification	Selection Instructions
Applicable storage temperature	0°C fresh‑keeping freezer to -40°C blast freezer	0–5°C fresh‑keeping cold storage: 75/100 mm; −18 to −25°C freezer: 150 mm; −35 to −40°C blast freezer: 200 mm.
Door panel material	0.7–1.2mm color steel sheet / 304 stainless steel	For food and pharmaceutical workshops, 304 stainless steel is preferred for its waterproof and corrosion‑resistant properties; standard color‑steel storage units offer excellent cost‑effectiveness.
Insulation core material	High-density polyurethane PU integral foam	Density: 48–52 kg/m³; closed-cell content: ≥95%; thermal conductivity: ≤0.022 W/(m·K); no thermal bridges throughout.
Door panel thickness	75mm, 100mm, 150mm, 200mm	The lower the temperature, the greater the door panel thickness must be.
Sealing system	EPDM low-temperature-resistant sealing strip	Surrounded by a sealed perimeter and an automatically sinking, pressure‑tight sealing strip at the bottom—remains flexible and leak‑proof even at –50°C.
Antifreeze configuration	Embedded self-regulating electric heating tape for door frames and thresholds	Standard equipped with a compressor operating at ≤−18°C to prevent the door frame from freezing and the door from getting stuck.
Custom-sized door openings	Single leaf: width 1000–6000 mm, height 1800–6000 mm; Double-leaf swing: maximum total width 12000 mm.	Large trucks and heavy-duty forklifts are equipped with double-leaf sliding doors.
Opening and closing method	Manual push-pull / Electric gear motor drive	The electric model features inverter‑controlled, cushioned start‑stop operation, ensuring smooth switching with no jolts.
Translational operating speed	0.2–0.3 m/s	Operates at low speed to minimize convective heat loss between warm and cold air.
Track structure	Thickened galvanized heavy-duty guide rail, with a floating-open, sinking-close structure.	The door automatically lowers and seals against the floor, enhancing airtightness.
Safety accessories	Infrared beam anti‑pinch, obstacle‑detecting rebound, indoor escape lock, audio‑visual warning	The electric model comes fully equipped to prevent pinching of people or goods.
Hardware accessories	304 stainless steel pulleys, hinges, and locks	It does not rust or jam in high-humidity, low-temperature environments.
