What is the advantage of employing the 'GRID' system in modern vessels?

Each grid or section of piping has its own independent supply and return direct to the evaporator and brine tank.

How is the system of air circulation maintained for temperature regulated cargoes?

By two sets of fan: one forces pre-cooled air along trunks and ducts to the compartment, while the other extracts air from the compartment when it becomes overcharged.

Why is the 'GRID' system preferred over continuous piping in modern vessels?

Because each grid or section of piping has its own independent supply and return direct to the evaporator and brine tank.

What happens if one grid in the 'GRID' system becomes choked?

<p>The temperature may be maintained by increasing the brine supply through the other grids.</p> Signup and view all the answers
