The temperature of a parts washer tank can vary depending on the specific type and model of the parts washer. Parts washer tanks are typically designed to operate at temperatures between 100-180 degrees Fahrenheit (38-82 degrees Celsius). The exact temperature range may also depend on the type of cleaning solution used in the parts washer. Always consult with the manufacturer for their recommendations. The good news is that belt skimmers can be used for skimming oil out of the parts washer tank. Our recommendation is our Belt Skimmer with a stainless steel belt as a regular polyurethane belt will not work. The stainless belts that Zebra Skimmers stock have a max operating temperature of 212ºF.
