18.5KW 25 HP 100 CFM Industrial Rotary Screw Air Compressor For Sale

We use the famous brand Hanbell airend. They produce the rotor with German processing equipment. Thus it ensures parts dimensional accuracy. Bên cạnh đó, Hanbell airends are larger than domestic airends of the same model. So more exhaust. The bearings adopt the world brand – SKF. Reliable quality, low failure rate. bảo hành là 2 năm.

Our airend uses the toothed double helix structure. The gear ratio of male and female rotors is 5:6. It makes full use of rotor inter-tooth volume. Bên cạnh đó, the streamlined design increases the flow area of the intake and exhaust ports. Large rotors are with low speed. So less noise.

Our 25 hp industrial compressor uses a 38UH permanent magnet motor. It’s a kind of high-temperature-resistant motor. It does not lose magnetism at 180°C. The service life is more than 15 năm. Bên cạnh đó, it maintains extremely high motor efficiency at low speeds. When the air consumption is small, it has obvious energy-saving advantages. Because of the one-piece structure, our 25 hp screw compressor is small in size. So it saves space and is easy to assemble and disassemble.

PM motor protection class is IP54. So it can adapt to the harsh working environment. Ngoài ra, the motor is directly connected to the male rotor of the airend through a coupling. Therefore the transmission efficiency is high. Wide speed range and high precision. The efficiency of a permanent magnet motor is 3%-5% higher than that of an ordinary motor.

This air compressor has a frequency inverter. Vì thế, it can adjust motor speed in real-time according to the actual air consumption. So as to achieve the purpose of controlling the exhaust air volume. When the air consumption is low, the machine will automatically sleep. Như vậy, it can greatly reduce the energy loss.

Energy bills can often far exceed the cost of the air compressor itself. Frequency conversion can avoid frequent loading and unloading under the change of air consumption. Vì thế, variable speed drive air compressors can often save more than 30% of electricity bills. Hơn thế nữa, stable pressure output can avoid high load current loss.

Constant pressure air supply: precisely control the air supply pressure within 0.01MPa. Constant temperature air supply: Nói chung là, the constant temperature is set at about 85°C. This makes the lubricate oil work best. At the same time avoid high temperature stopping. Bên cạnh đó, it eliminates “No load”. Reduce 45% of no-load energy consumption.

Ngoài ra, it also eliminates excess pressure. For every 0.1MPa increase in air compressor pressure, energy consumption increases by 7%. Guarantee vector air supply and precise calculation. Cuối cùng, ensure that the air output of the screw compressor is always consistent with the demand of the user system.

This industrial rotary screw air compressor is easy to operate. The movement status of the air compressor is clear at a glance. It has automatic alarm protection for faults, such as motor short circuits, phase loss, and overload. Bên cạnh đó, it can automatically load and unload according to the air consumption. The machine can automatically adjust the exhaust air volume. It can also realize multi-unit connections and remote control.

The 25 hp industrial compressor uses an aluminum plate-fin cooler. The fin structure increases the secondary heat exchange area. It can promote turbulence and improve the heat exchange coefficient. Compared with similar models, the heat exchange area is increased by 30%. Hơn thế nữa, the margin is large. Even in hot and humid areas, it will not affect normal use.

The frequency inverter is a soft start device. The start-up shock is very small. There will be very low noise when starting up. Đồng thời, the operating frequency of the VSD air compressor is lower than that of the power frequency air compressor. So it greatly reduces mechanical noise.
