Layout
The best layout our engine found puts all 8 in a square grid. That covers 83.1% of the floor.
Leaving 100 mm of length and 50 mm of width free for handling costs 4 positions: the clearance layout puts all 4 in a square grid.
Floor and door
The 20 ft reefer container has 12.5 m² of floor (135 sq ft) inside. In the same box an EPAL 1 takes 10 positions against 8 for the CP3, so the CP3 pallets cover 10.4 m² against 9.6 m² for EPAL 1.
The door opening is 2,290 mm wide, so the CP3, carried narrow side first, clears it by 1,150 mm.

Height and weight
Empty CP3 pallets are 138 mm high. The lower of the inside height (2,273 mm) and the door height (2,221 mm) is 2,221 mm, so 16 fit in one stack and 64 across the 4 clearance positions, weighing about not published, which is over the 27,700 kg guideline payload.
For loaded pallets stacked two high, each unit including its pallet can be at most 1,110 mm tall, which leaves 972 mm for goods on each CP3.
If all 4 clearance positions are filled in one layer, the guideline payload allows on average 6,925 kg of goods per pallet.

How this is computed
The engine tries every split of the deck into rows of pallets placed one way and rows placed the other way, along the length and across the width, and keeps the arrangement with the most pallets. It does not overhang, mix in other pallet sizes or allow for bulging goods. The methodology page explains each step, and the load planner runs the same code on your own dimensions.
