Hydraulic oil coolers function by circulating oil through a radiator connected to a fan, which forces air over the radiator. This process cools the hydraulic oil while simultaneously warming the air entering the lines, helping to prevent clogging from sticky fertilizers and seed treatments.

When run with a snorkel, it helps remove humidity by pulling drier air from higher up, which is also cleaner air, so you reduce the amount of dust and debris that could cover the radiator. Snorkel kits are available with or without the oil coolers, for air carts and air boom applicators.
