TV-series
Oil-free compressed air for the automotive sector
TV-series oil-free piston compressor
Piston (cylinder)
A special tribological coating
on both
the piston and the cylinder wall
ensures
minimal friction,
making oil or water cooling
a thing of the past.
Motor
The engine is directly connected to the pistons
by means of a crankshaft. You benefit from this
highly efficient transmission.
Fan
The fan rotates with the pistons'
movement. This provides the necessary
air cooling, making the compressor
100% loadable.
The TV series has been developed from the need for less maintenance and lower maintenance costs. The fact that this compressor has no oil as a coolant/lubricant means that the main cause of necessary maintenance and possible malfunctions has been removed. An additional advantage for you is that the compressor can work continuously and does not require a cooling time.
The transmission of the energy from the electric motor to the pistons is directly coupled to the electric motor by means of a crankshaft. As a result, no energy is lost.
Meanwhile, the TV series has proven itself in generating oil-free compressed air in the automotive-sector and is therefore proof that long-term application is possible at very low maintenance costs. The TV series forms an excellent basis for, for example, generating oil-free compressed air for breathing air* or application in the dentistry.
The TV-series is available with both an induction motor and a PM motor**.
* Compressed air must be prepared at all times before it can be used as breathing air
** a PM motor must be controlled by a frequency inverter.

Your benefit: Low maintenance Efficient Continuous operation No maintenance on refrigerants No maintenance on V-belts
Oil-free piston compressor
A piston compressor uses one or more pistons to compress air. The chamber in which the piston is located keeps changing its volume size. When the room gets bigger, it draws in outside air. When the room gets smaller, the air is compressed. This process releases a lot of heat. Traditional models are designed for oil or water cooling. To preserve the machine and the refrigerant, it is necessary that these refrigerants cool down, for this the machine must be stopped. Therefore, you can only use this compressor in non-continuous applications. (approx. 60% runtime/40% cooling time).
This is where Naili makes the difference for you compared to the traditional piston compressor. Due to the special coating on the piston and the inside of the cylinder, you do not need to cool with oil or water. The compressor is air cooled. Your big advantage is that you can use the compressor 24/7. In addition, you do not need to maintain refrigerants.
The transmission of the energy from the electric motor to the pistons is done by means of V-belts in many traditional piston compressor models. You must maintain it properly. In addition, this form of drive results in a loss of efficiency. The oil-free piston compressors are directly connected to the electric motor via a crankshaft.
Where you normally have to perform a lot of maintenance, with this type you only need to replace the piston ring once every 8,000 hours; a few minutes' operation.
Traditional
Oil and water cooling
These refrigerants must cool down, forcing you to interrupt operation.
Intermittent operation
Due to cooling time, you can only use the traditional compressor for non-continuous operation.
Energy transmission through V-belts
The downside is that you have to maintain the V-belts and it reduces your efficiency.
Naili
Air cooled compressor
A low friction coating on the pistons and cylinders allow air-cooling.
Continuous operation
There is no cooling time for refrigerants and no time spent maintaining them.
Energy transmission through a crankshaft
These compressors are directly connected to the electric motor via a crankshaft.
