Coral Pod C20
The Coral Pod C20 is a 20ft ISO container carrying two 42U immersion tanks, 84 rack units and 400 kW of thermal capability in a 13.9 square metre footprint. It is the smallest Coral container pod and the one that fits where a 40ft cannot: constrained yards, rooftop plant decks, remote sites and anywhere a standard 20ft delivery is the only viable access.
Headline figures.
Where the C20 is the right answer
Sites where delivery access rules out a 40ft. Rooftop and podium deck installations where the structural allowance suits a shorter, lighter unit. First deployments where the customer wants a single pod in production before committing to a factory. Remote and forward deployments where a 20ft is the standard logistics unit.
The C20 uses an external plant skid rather than an internal plant bay, because in a 5.90 metre internal length the space is better spent on tanks. That skid can sit alongside the container or on the roof.

How many GPUs fit in a 20ft container data centre?
A Coral Pod C20 provides 84 rack units across two 42U immersion tanks. Populated with 8U 8-GPU HGX class nodes that is ten nodes and 80 GPUs, drawing 102 kW at H200 class or 143 kW at B200 class against 400 kW of thermal capability.
Can a 20ft pod be installed on a roof?
Subject to structural assessment, yes. The C20 has an approximate gross weight of 7.7 tonnes with a floor loading of 855 kg per square metre at each tank position, and the plant skid can be co-located or separated. Structural sign-off is part of the site assessment stage.
