Reefer Container Courses

Reefer containers carry cargo of perishable nature. Hence they require proper operation and maintenance throughout transportation. It is essential that Marine Engineers and Electrical Officers are well trained for same with adequate knowledge and skill to operate, maintain and troubleshoot the systems. These courses improve the same by lectures, group discussions, hands on training, simulation exercises, and logical troubleshooting with a refrigerated container and associated means.
