FIDEM Industrial Oil Chiller – Precision Cooling for Spindle & Machine Oils
FIDEM Industrial Oil Chillers are high-performance refrigeration units specifically engineered to control the temperature of spindle and hydraulic oils in CNC and precision machinery. Operating on the vapor compression refrigeration cycle, these chillers continuously circulate oil in a closed or open loop, efficiently extracting excess heat to maintain a stable working temperature—resulting in improved machining accuracy, surface finish, and tool life.
Unlike water-cooled chillers, FIDEM oil chillers use air-cooled condensers, eliminating the need for a cooling tower and simplifying installation and maintenance.
Types of Industrial Oil Chillers
- 1. Box-Type Oil Chiller – Compact and self-contained, ideal for CNC and EDM machines.
- 2. Immersion-Type Oil Chiller – Chiller coil directly immersed in oil tank.
- 3. Circulating Oil Chiller – For large volume oil cooling, with external circulation system.
- 4. Customized Solutions – Tailored for non-standard installations or high ambient applications.
Key Features & Advantages
- Panasonic / Danfoss Scroll Compressor – Energy-efficient and reliable
- Eco-Friendly Refrigerants – R410A / R407C (non-ozone depleting)
- Built-in SS304 Oil Tank – For stable circulation and temperature
- Integrated Oil Pump – Ensures continuous flow through system
- PHE or Shell & Tube Evaporator – Durable and high thermal efficiency
- Digital Temperature Controller – Microprocessor-based precision control
- Safety Protection – High/low pressure switch, temperature alarm, and flow switches
- Compact Design – Easy to install beside CNC or machining centers
How Does an Industrial Oil Chiller Work?
- 1. Oil Circulation – Warm spindle or hydraulic oil is drawn from the machine.
- 2. Heat Exchange – The oil passes through an evaporator (PHE/Shell & Tube), where heat is transferred to the refrigerant.
- 3. Cooling Process – The refrigerant absorbs the oil's heat and moves it to the condenser where it is released to the ambient air via fans.
- 4. Cooled Oil Return – The cooled oil is then pumped back into the machine, keeping the spindle or system within ideal temperature limits.
