For the vacuum chamber, three different types of doors can be used:
- Standard swing door: Most simple construction, manual operation. The ramp for this system is mounted inside the cooling chamber.
- Horizontal sliding door: This electrical driven door is optimal if the cooling skid is placed besides the vacuum chamber (one pallet model and > 6 pallet systems).
- Upward lift door: Hydraulic system, suggested solution for all systems from 2 – 6 pallets. Easy installation, easy ramp construction.
It is also possible to use two doors in combination with a roller belt system, for maximum efficiency of the (un)loading process.
