T-Light cold storage door

Cold storage door is the most direct temperature control component in an entire industrial cold storage system. Every time goods move in or out, the door takes the heaviest heat exchange load — if it does not seal properly, the compressor has to run continuously to make up the heat, which drives electricity costs up sharply and shortens equipment life.

Tan Long is the exclusive distributor of the cold storage door line T-Light imported 100% from Europe. The products carry a certificate of origin (C/O) and a quality certificate (C/Q), and suit chill rooms, freezer rooms and deep freezing tunnels down to -45°C.

Cold storage doors are specially designed to retain heat.

What is a cold storage door? Its role in holding temperature in the room

A cold storage door is the temperature control component at the entrance of the room. Each time it opens and closes, hot humid outside air flows into the cold chamber, forcing the system to run to pull the temperature back to setpoint. The quality of the leaf, the insulation core and the tightness of the gasket therefore have a direct effect on power consumption and on the service life of the compressor set.

Which types of cold rooms are T-Light cold storage doors suitable for?

Product line cold storage door T-Light, supplied directly by Tan Long, is designed specifically to serve the full demanding temperature range found in industrial refrigeration systems today:

  • Chill rooms (temperature from +2°C to +8°C): This is the ideal environment for storing vegetables, fruit, pharmaceuticals and post-harvest produce. For this segment, customers usually prefer the cold storage door hinged or sliding line with a 75mm PU insulation core to optimise cost while still ensuring performance.
  • Cold storage rooms (temperature from -2°C to -18°C): Suitable for storing meat, fish, seafood and processed foods. For these systems, Tan Long recommends installing cold storage door with a 100mm PU core to stop heat loss completely and protect product quality to the maximum.
  • Deep freezer rooms (temperature from -18°C to -25°C): Widely used for long-term frozen food storage. The cold storage door line for deep freezer rooms requires a PU core from 100mm to 125mm and must include a door frame heater system to prevent the gasket being frozen stiff.
  • Air blast freezing tunnels and IQF systems (extremely low temperatures from -35°C to -45°C): This is the harshest operating environment and requires cold storage door to have a PU core of 125mm or more. The equipment must also use a high-power frame heater system combined with special rubber gaskets able to withstand continuous deep sub-zero temperatures without deforming, so that it works alongside the IQF belt freezer or the wind tunnel in the plant.

Loading Dock DoorLoading dock area, against the container trailerTo the dock opening size of the buildingSeals the gap between the trailer and the warehouse wall, blocking heat and dust during loading and unloading

Materials and construction details of the standard T-Light cold storage door

Understanding the construction of the cold storage door in detail helps the investor judge product quality and long-term value accurately, instead of only comparing surface prices on the market.

  • High-density PU (polyurethane) insulation core: This is the core component that determines the R-value of the door leaf. The T-Light cold storage door line uses a PU core with a density of 40 kg/m³. This is the ideal density for eliminating all voids inside the leaf, ensuring stable temperatures over time. The PU core thickness is flexible from 75mm to 125mm, covering everything from chill rooms (+2°C to +8°C) to deep freezing cold storage systems from -40°C to -45°C.
  • Door leaf surface material: Depending on the operating environment, customers can choose 0.5mm to 0.8mm powder-coated steel sheet for dry areas. For high-humidity environments or environments in frequent contact with cleaning chemicals, such as seafood processing plants, Tan Long prefers SUS 304 stainless steel to resist rust and corrosion.
  • Anodised aluminium or SUS 304 stainless steel door frame: An anodised aluminium frame system is excellent at preventing oxidation. This matters particularly in environments cold storage door in frequent contact with caustic soda (NaOH) or acid cleaning agents during industrial cleaning.
  • Dedicated multi-layer rubber gasket system: The rubber gasket grips the door frame tightly around the entire perimeter and withstands deep sub-zero temperatures without becoming brittle or cracking. This is the key detail that determines tightness and prevents heat loss for the whole cold room enclosure.
  • European imported locks and hinges: Tan Long uses fittings from specialist global brands such as Stuv, Intertecnica and MTH, manufactured in Europe. These fittings not only meet demanding food industry standards but also include an emergency release from the inside, in strict compliance with occupational safety regulations for operating industrial refrigeration systems.

Depending on your needs, choose the right type of cold storage door.

Why does door quality affect cold storage operating costs?

In a standard cold storage system, the door area is the strongest heat exchange point, not the wall or ceiling panels. Each time it opens and closes, a large volume of cold air escapes and hot humid air from the environment flows in. If the cold storage door system has a leaking door gasket or a poor-quality insulation core, this heat loss continues quietly even when the door is shut.

Technically, heat leakage forces the refrigeration compressor to run continuously at higher capacity to make up the heat lost. Based on actual data from projects Tan Long has built and operated, facilities using poor-quality cold storage door can consume 15% to 25% more electricity than doors that meet standards. In economic terms, that difference can cost tens of millions of dong in extra electricity every year for each cold store.

For deep freezer systems operating from -18°C to -25°C (equivalent to 0°F to -13°F), the problem becomes more serious. Moisture entering from outside condenses and freezes right at the door frame, jamming the door or ruining the rubber gasket after only a few months of operation. The T-Light cold storage door solution from Tan Long deals with this completely through an integrated frame heater system. This technology prevents frost forming on the frame entirely, keeps opening and closing smooth and maintains maximum mechanical durability under continuous deep sub-zero conditions.

Cold storage doors are commonly used in cold storage systems.

Choosing leaf thickness by cold room temperature range

For both the hinged (TLH) and the manual sliding (TLS) lines, the leaf thickness is chosen by the operating temperature of the room, not by the door size:

Warehouse typeTemperature rangeModelLeaf thickness
Cool storage0°C to 8°CTLH75 / TLS7575 mm
Deep-freeze store0°C to -28°CTLH100 / TLS100100 mm
Freezer0°C to -45°CTLH125 / TLS125125 mm

From 100 mm upwards, the door is fitted with heater wire in the frame to keep the gasket and frame from freezing at sub-zero temperatures. Choosing too little thickness is the most common reason doors collect moisture, build up frost and lose gasket contact after only a few seasons of operation.

For areas where goods need to be seen without opening the door, there is the option of a cold storage with glass doors — it holds the temperature and still lets you see the goods.

Frequently asked questions about cold storage doors

How many mm thick should a cold storage door be?

The PU core thickness is chosen by operating temperature. Chill rooms at 0°C to 8°C use 75 mm; cold rooms at 0°C to -28°C use 100 mm; freezer rooms down to -45°C use 125 mm. This rule applies to both the hinged (TLH) and the manual sliding (TLS) lines.

Is a door frame heater mandatory?

It is mandatory for freezer rooms at -10°C and below. Without a frame heater, moisture from outside freezes at the frame, jamming the door and ruining the gasket after only a few months. The T-Light line from 100 mm upwards already has heater wire in the frame.

Which is more suitable for a room with forklifts, a sliding door or a hinged door?

Sliding doors. When fully open, the leaf slides to one side and does not obstruct the forklift route; the maximum size is 3,000 × 6,000 mm. Hinged door needs a swing area to open and is limited to 1,390 × 2,850 mm, which suits personnel access.

How long does it take to install one door set?

Normally 1 to 2 days for a single door set, depending on size and type. On projects with many doors, Tan Long phases the work so the room can keep operating during installation.

Which door type does the loading and unloading area need?

The loading dock area needs a Loading Dock Door package comprising a dock shelter, a hydraulic dock leveller and a roller shutter. This is the largest heat loss point of a cold store, because the door opens to the outside throughout loading and unloading.

Does Tan Long supply cleanroom doors?

Yes. In addition to the T-Light cold storage door lines, Tan Long supplies cleanroom doors to the technical requirements of GMP-standard pharmaceutical and food plants.
