The Nikuni C-CAT standalone hydrocyclone separator

The Nikuni C-CAT is a standalone maintenance-free filtration system incorporating the VDF hydrocyclone. It is fitted with its own solids tolerant pump, frame-mounted and can be either dedicated to one machine or used mobile around the plant or work-space.

Technology developed and applied...

The Nikuni C-CAT filtration system was developed for use with machine tools to provide a simple maintenance-free solution to clean metallic contamination from water-based coolants. It incorporates a Nikuni VDF hydrocyclone and can be retrofitted to many existing machines without major modification to the coolant system tank.

Typical Nikuni C-CAT single-pass metallic particle removal performance on aluminium in water-based coolants is:
• 99% of all metallic particles down to 25µm
• 98% of all metallic particles down to 15µm
• 95% of all metallic particles down to 10µm
• 90% of all metallic particles down to 5µm
• 65% of all metallic particles down to 3µm

C-CAT model range includes:
• 20 lpm
• 30 lpm
• 50 lpm
• 70 lpm
• 100 lpm
• 200 lpm
• 300 lpm
• 1,000 lpm (under development)

The benefits of installing a C-CAT include:
• Cleaner coolant and a longer life-cycle
• Reduced tool wear
• Superior surface finish
• Shorter cycle times
• No filter elements to block
• No filter elements to change
• More machine tool up-time and less downtime

The C-CAT can be used with either water-based or oil-based coolants. When used with oil-based coolants the higher viscosity of the oil-based coolant may require a higher than normal working pressure.

C-CAT flexibility:
A C-CAT can be used as:
• Primary filtration
• Secondary filtration
• As a back-up to existing filtration systems
• To extend the life-cycle of existing replaceable media
• As a standalone with adjustable feet
• As a mobile unit with castors (options on castor tyre available)

C-CAT sludge pod
A Nikuni C-CAT can also be supplied with a sludge pod, in order to accumulate and consolidate separated materials into a drier waste with little coolant.

C-CAT sludge pod benefits:
• Reduces the volume of coolant in circulation
• Saves coolant
• Saves energy
• Reduces operational costs
• Manual or automatic operation (air-operated dump valve)

C-CAT is available as either a kit of parts for self-assembly or a fully assembled package.
C-CAT options include:
• Sludge pod in SCS13 stainless steel
• Sludge pod in acrylic (used to observe separation activity)
• Manual dump valve
• Air operated dump valve
• Motor controls
• Motor controls with integrated dump valve timer control
• Waste container

C-CAT assembled package includes:
• Nikuni VDF hydrocyclone
• Coated or painted mild steel frame
• Solids tolerant pump
• Hoses and fittings
• Pressure gauge
• Sludge pod
• Sludge pod valve (manual or automatic)
• Pressure gauge

C-CAT installation requirements:
• 3 phase 415V 50Hz power supply
• Suction tube
• Clean fluid discharge tube
