Unlike heavy traditional doors, the Tan Long high speed roller door has a light structure, comes in a range of colours and is very easy to clean regularly. In particular, its flexible installation means the equipment can be dismantled, moved and reused when the business needs to change the plant layout. Investing in the quick open and close door This is a strategic step to minimize energy waste and affirm modern operating standards for all industrial projects today.
Why choose a high speed door from Tan Long
The four points below are all verifiable, not self-assessment:
| Criteria | Details |
|---|---|
| Materials stated openly | SUS304 stainless steel leaf and frame 0.5 – 0.8 mm or RAL colour-coated steel 0.46 mm · PU core at 40 kg/m³ · anodised aluminium frame with a thermal break channel. |
| Imported fittings | Hinges, suspension mechanisms and locks from Stuv, Intertecnica, Imamoglu and MTH (Europe) — with model codes for reference when replacement is needed. |
| Installed in the field | 29 projects since 2005 for seafood plants, food plants and distribution cold stores. See the project portfolio. |
| Same contractor as the cold store itself | Tan Long turnkey cold storage installation, so the door is chosen to match the panel thickness and the temperature range from the design stage, rather than being fitted as an afterthought. |
Scope of work: survey the door opening and temperature range → select the model and leaf thickness → supply and install → adjust the gasket, heater wire and lock mechanism → operator training → periodic maintenance under the contract.
Comparing the 4 types of cold storage door Tan Long supplies
A cold store usually uses more than one type of door: a door for people, a door for forklifts, and a door at the loading and unloading area. The table below compares them on actual parameters so you can choose the right type for each position:
| Door type | Suitable installation position | Maximum size | What to weigh up |
|---|---|---|---|
| T-Light hinged door (TLH) | Personnel access, small and medium rooms | W 1.390 × H 2.850 mm | Lowest investment cost, but needs clearance for the leaf to swing |
| T-Light manual sliding door (TLS) | Forklift access, large openings, high-volume rooms | W 3.000 × H 6.000 mm | Takes no space when open, needs a sliding rail along the wall |
| High-Speed Door | High-traffic passageways between two areas at different temperatures | W 4.000 × H 5.500 mm | Opens at 2.4 m/s and closes at 1.2 m/s, so cold loss drops sharply; it has a motor and a control panel, so it needs periodic maintenance |
| Loading Dock Door | Loading dock area, against the container trailer | To the dock opening size of the building | Seals the gap between the trailer and the warehouse wall, blocking heat and dust during loading and unloading |
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 type | Temperature range | Model | Leaf thickness |
|---|---|---|---|
| Cool storage | 0°C to 8°C | TLH75 / TLS75 | 75 mm |
| Deep-freeze store | 0°C to -28°C | TLH100 / TLS100 | 100 mm |
| Freezer | 0°C to -45°C | TLH125 / TLS125 | 125 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.
Comparison with other cold storage door types
The high speed door solves cold loss at busy vehicle routes. Positions with less traffic do not need this type:
- T-Light hinged door — the lowest cost, suited to secondary doors or rarely used routes.
- T-Light manual sliding door — takes no space for a swinging leaf, suited to narrow walkways and large openings.
- Loading dock door assembly — for the position adjoining the truck, where airtightness against the trailer is required.

Frequently asked questions about high speed doors
Can a high speed door be used for a deep freezer room?
Yes. However, the curtain must be a dedicated cold-resistant type and the motor must have heating so that it does not seize through freezing. For a freezer room, these are two items that should be stated explicitly in the contract rather than left to the standard configuration.
What are the actual opening and closing speeds?
A maximum opening speed of 2.4 m/s and a closing speed of 1.2 m/s with the standard curtain. It is the short time the door stays open that determines how much heat and dust get in, not the thickness of the curtain.
How is the door opened during a power failure?
Use the mechanical hand crank built into the motor to open it manually, or add a backup power supply. For a mandatory emergency exit, one of these two options is required.
Can a high speed door replace a PVC strip curtain?
Yes, and it seals far better. A fixed PVC strip curtain always has gaps between the strips, while a high speed door forms a tight barrier when closed. In return, the high speed door has a motor and a control panel, so it needs periodic maintenance.
What are the standard dimensions and motor power?
A maximum opening of 4,000 mm wide × 5,500 mm high. A 4-pole motor, 1.5 kW, rated IP65. The control panel is IP54 and comes with an isolator, an adjustable timer, an open button, a reset button and an emergency stop button. The frame is galvanised steel 80 × 40 × 3 mm, with a stainless steel option.
Where in the cold store should a high speed door be installed?
At high-traffic passageways between two areas with a temperature difference — for example between the production area and the chill room, or a forklift route in continuous use. For routes with little traffic, the manual sliding door or hinged door makes more sense in terms of investment and maintenance cost.
