An immersion oil chiller（drop in oil cooling unit） is an industrial cooling device that works by placing the evaporator (cooling coil) directly within an oil tank or coolant reservoir. Unlike traditional oil coolers, it typically does not have a circulation pump. Instead, it relies on the existing fluid flow within the tank or an optional agitator to maintain a uniform liquid temperature, making it ideal for cooling coolants, hydraulic fluids, lubricants, and high-viscosity industrial fluids.
TOBEL immersion oil chiller provides direct, in-tank temperature control for cutting fluids, hydraulic oil, and lubricating oil across a wide range of machine tools, including machining centers, grinders, broaching machines, grinding machines, WEDM, EDM machine tools, cooling systems, hydraulic systems, and lubrication systems. The corrosion-resistant stainless steel evaporator coil submerges directly into the fluid, rapidly extracting heat without dilution or contamination, ensuring temperature stability to prevent thermal expansion and maintain machining accuracy.
