Envco – Environmental Equipment

High Viscosity Skimmer (TR-70410) - Is used when the product has a viscosity higher than 80 SSU, such as oils. The 4-in high viscosity skimmer uses the same design as the TR-517, less the hydrophobic and bypass screen. The skimmer has 30-in of travel and a specifi c gravity of 0.95, allowing it to fl oat at the water/product interface. The product collects on top of the skimmer inlet and from there it is pumped to the surface. In normal applications, the skimmer will remove product down to a product layer of ¼ in to ½ in. The skimmer can be adjusted in the fi eld to remove the product even further and attain a thinner layer.

Product Recovery Canister.
The clear PVC collection canister uses a quick connect fitting to attach it to the skimmer and provides venting through the skimmer support hollow rod. The bottom of the canister incorporates a petcock for easy draining. The petcock assembly can be removed allowing an extension canister to be threaded into the existing canister to increase the volume of free product that can be recovered. Additional weights are included with each canister and must be used for proper installation.

Three types of skimmers are available: standard, high-viscosity, and density. Note: Density skimmers are not compatible with the F.A.P. Plus ZW. To use a density skimmer, you can either purchase a conversion kit (TR-51699) or you can purchase the F.A.P. Plus pump (TR-516).
