Product Description:
The first single-inlet single-flow roller with spiral flow channel
1. The inlet and outlet of media are located on both sides of the roller.
2. Medium: cold water or hot water, heat transfer oil
3. The temperature difference is about 0.5 degrees
The second type of single-inlet double-flow roller with spiral flow channel in the tank
1. The inlet and outlet of the medium are on the same side. The medium flows in through the siphon and is discharged along the spiral channel and through the same journal hole (siphon)
2. The medium heats the roller through two directions of fluid in the roller, which makes the roller heating faster.
3. Medium: hot or cold water, heat transfer oil
4. The temperature difference is about 0.5 degrees
The third type of double-inlet and double-flow roller with inner spiral flow channel (suitable for low-speed roller)
1. There are inlets and outlets on both sides of the roller. The medium flows in through the siphon and is discharged along the spiral channel and through the journal holes on both sides (siphon)
2. The medium can cover the surface of the roller more quickly, and the design of double-in and double-out of the medium improves the working efficiency of the roller.
3. Only applicable to low speed roller
4. Medium: hot or cold water, heat transfer oil
5. The temperature difference is about 0.5 degrees
The fourth type of double-inlet and double-flow roller with inner spiral flow channel (applicable to the roller with long roll surface)
1. There are inlets and outlets on both sides of the roller. The medium flows in through the siphon and is discharged along the spiral channel and through different journal holes on both sides (siphon)
2. Effectively reduce the internal pressure of the roller
3. Suitable for rollers with long roll surface
4. Medium: hot or cold water, heat transfer oil
5. Temperature difference is about 0.5 degrees
Counter-current roller of the fifth kind of inner spiral channel
1. The medium inlet and outlet are on the same side. The medium flows in through a siphon and is discharged through the same journal hole along the spiral channel
2. With countercurrent system
3. Medium: hot or cold water, heat transfer oil
4. The temperature difference is about 0.5 degrees
The heating roller is widely used. We can develop heating rollers with different roller structure according to your needs.
