• Oil-water separator

**Overview** ◇ Floating Oil Recovery/Separation Device (Oil Skimmer) **Catchphrase** ◇ With a wide range of applications, it meets the needs of various sites, including explosion-proof, corrosion-resistant, and high-temperature liquids. ◇ Suitable for sites in food, chemicals, automotive, steel, power plants, refineries, and more. **Features** ◇ The floating oil recovery float section features a patented double float structure, providing unmatched liquid level tracking and recovery performance. ◇ With the standard adoption of an inverter, it allows for stepless pump speed adjustment. By balancing the inflow rate of the float and the pump recovery rate, it minimizes unnecessary oil-water agitation, achieving improved separation efficiency and reduced pump wear. ◇ The oil-water separator is equipped with a patented forced oil discharge mechanism (large scraper for high viscosity) as standard. ◇ It effectively scrapes and discharges difficult-to-extract food oils, such as animal and vegetable oils, as well as low-fluidity recoverables like bonding agents and paint residues. The floating oil recovery device is developed with a focus on eliminating dead space in the scraper by designing the shape of the separator. ◇ Capable of recovering high-temperature liquids, with an easy-to-maintain SUS304 separator. *For more details, please contact us.*

• Oil-water separator

A high-temperature cleaning liquid oil skimmer that boasts a heat resistance of 95°C. It is a device that combines a "pump for recovering coolant" and a "separator for separating oil and water." The recovery pump uses a seal-less screw pump, which is a patented, specially designed product developed and designed specifically for this device. The separator employs a gravity separation method without consumables, making maintenance easy. Proactive removal of floating oil contributes to maintaining the performance of the cleaning liquid and can significantly extend the liquid replacement cycle. Additionally, the reduction in waste liquid volume leads to cost savings.

• Oil-water separator

This is an oil recovery and separation device (oil skimmer) that floats in the coolant pit of machine tools. It was renewed in December 2016 as the definitive solution for preventing the decay of water-soluble coolants. Retaining the performance that has received positive feedback, it has been transformed into a stylish design that enhances mobility and convenience. With an air-driven system that requires no power supply and a compact wagon type, it can be easily moved around the site and is capable of recovering floating oil from multiple machines with just one unit. ★On-site demonstrations are available. Please feel free to contact us!
