Disk Skimmers
Disk skimmers work by mounting to the top of the tank and running a large diameter disk into the coolant surface. The disk itself is made of either plastic or stainless steel. As the disk passes through the coolant surface, oil is picked up and wiped off with a set of wiper blades as the disk passes between them.
Advantages for disk skimmers are a slightly higher pick up rate than other types of skimmers and lower cost.
Disk skimmers do require a larger operating space to accommodate the disks. The pick up rate drops dramatically if the fluid level does not cover at least half the surface of the disk, making it unsuitable in tanks where the fluid level fluctuates.
