PRODUCT details

: Twin-screw high-efficiency airend● Newly developed for industrial vacuum applications. Reliable, efficient and low noise. ● Screw technology is more efficient than other technologies (rotary vane, water ring, etc.).

: Specialized permanent magnet motor ● Using high coercive force and high temperature resistant permanent magnets to ensure 150℃ without demagnetization. ● Built-in PTC temperature protection to prevent demagnetization caused by high temperature due to failure.

: Specialized inverter
● Synchronous, easy frequency control, good dynamic response performance, can quickly respond to a wide range of adjustment and accurately regulate the vacuum degree. ● VSD regulation start. Smooth start. Reduce the impact on the grid.

: Imported filters
● American imported filter. ● Equipped with pre-filter design. High dust capacity. 99% filtration efficiency @5micro. Fully guarantee the safe operation of the airend.

: Lube oil cooling system
● Uses dedicated synthetic lubricant with a life expectancy of 8,000 hours.
● Lubricant cools the airend, which is then cooled by the cooler

: Instrumentation and electronic control system
● Using instrumentation and electrical control.
● Indication of exhaust temperature, oil/air separator tank pressure,system vacuum level.

: Specialized inlet valve for vaccum application
● Ultra-low throttling loss. Contributing to the overall efficiency of the vacuum pump. ● Automatic adjustment of the valve opening according to the load capacity to automatically maintain the system vacuum within the set range.

: Oil/air separator tank
● Using similar design like air compressor. The oil content of exhaust air is less than 3PPM.
● Tangential air inlet design with baffle plate in the inner skirt to achieve cyclone separation and impact separation effect.

: No-loss direct drive
● Using motor direct drive. Rotor speed and motor speed consistent.
● The main motor is connected to the airend with a "C" flange to make the motor and the airend a rigid body and keep the axis in alignment.

ENERGY SAVING COMPARISON

	Rotary vane pump solutions	SCR permanent magnet VSD oil-injected screw vacuum pump
Equipment situation	15 x Rotary vane pumps	4 x SCR1300VSPM
Pumping speed	300m³/H *8=2400m³/H	1300m³/H*2=2600m³/H
Total power of vacuum pump	7.5kw * 15=112.5kw	22kw*4=88kw
Deep freezer	15kw * 4=60kw	Not required
Energy saving situation	Fixed speed rotary vane vacuum pump.Full load after running.	VSD screw vacuum pump. Frequency range of 12%~100%. Operation can achieve 25%~50% energy saving effect.
1 year operating power	(112.5kw+60kw)24h350days =1.45 million kWh	88kw24h350 days*70%=520,000 kWh
1 year power saving	/	VSD screw vacuum pump can save 930,000 kWh/year
1 year savings on electricity	/	930,000 kWh * 0.7 = 650,000 RMB/year
Management	The number of equipment is too many, and the maintenance workload of rotary vane pump is large. It takes up a lot of labor.	The equipment runs stably and requires only regular maintenance, saving a lot of labor.
Service life	/	Screw vacuum pump equipment is stable and has a service life of 15~20 years.
