A stock model is not rejected in this sector for a weakness in its specification. It is rejected because it stops at a limit in length or height — and the defense platform exceeds that limit by design.
Oversize platform chamber sizing starts from the first input: the chamber is built to the platform’s envelope, within a published range reaching 24,000 mm long and 6000 mm high.
Why the stock model stops
The standard automotive size in this family is an internal chamber of 6900×4000×2650 mm, built around the civilian vehicle. Defense vehicles and platforms are longer, taller and heavier than their civilian equivalents, so the gap is not closed by configuring within that envelope but by building the chamber on the platform’s dimensions.
The published range and the main door
| Item | Delivered range |
|---|---|
| Chamber dimensions | Length 3000–24,000 mm · height 2650–6000 mm |
| Main door size | Up to 14,200×5,000 mm, electrically operated on large builds |
| Air capacity | 18,000–190,000 m³/h per supply or extraction set |
| Heat output | 200,000–600,000 kcal/h |
Why the door enters the calculation early
A wide or tall platform needs an entry opening beyond a standard door, and at that size electric actuation becomes necessary rather than optional. The door is therefore not an accessory chosen at the end of configuration but a constraint on the opening, fixed with the internal size.
Frequently asked questions
What is the largest platform size that can be accommodated?
The published build range reaches 24,000 mm long and 6000 mm high, with a main door up to 14,200×5,000 mm operating electrically. The final size is built on the platform’s own dimensions.
Does a larger chamber raise the air capacity required?
Yes. A larger chamber raises airflow and heat demand — what separates a defense build from an automotive booth — and the delivered range reaches 190,000 m³/h per supply or extraction set.
What is sent to fix the size?
The vehicle or platform dimensions and the project scope. The written technical specification fit for a tender document is built from those two.
Is finishing delivered for fixed platforms as well as vehicles?
What is published for this sector is heavy vehicle and large equipment sizes within the range above, special finishes, and site and security requirements defined per project.
