d>  used road paver 
1)  QT4-20 automatic pavers factory sale : PLC intelligent control.Man machine interface,control system equipped with complete logic control,production program,malfunction diagnosis system and remote control function.It doesn't need a professional person but only need a simple trainning to the operator. 
2)  QT4-20 automatic pavers factory sale : 
Multifunction in one machine.Changing molds can produce various kinds of specification porous bricks,standard bricks,hollow bricks,with a double material-feeding machine can produce all kinds of the colored road bricks, grassland
 bricks, and slope protection bricks etc.
3) QT4-20 automatic pavers factory sale :
It is a compact oil hydraulic machine according to the standard of international.Many parts from abroad ensure the quality of machine and take from the power.
4) Concrete brick machine price QT4-20 brick machine price:
Vibration system contains platform vibration and mould vibration.The platform vibration was drived by hydraulic oil and program,bringing a vertical and synchronal vibration and achieving low frequency in feeding material,high frequency making.According to different product,we can change the vibration.
5) pavement machine :Application of digital control systems and sensor technology,combined with effective and makes all act exactness and trustiness.So that it is the same with different conditions.The adoption of a variety of advanced technology is easy to be operated.The system is of fault diagnosis system.

Economizer with exhaust damper, fresh air damper, returan air damper and exhaust air damper. The dampers can be automaticlly controlled by PLC controller or by manual based on project needs.

This type HVAC system is another energy saving in the field of Air Conditioning. 

Interlocked to run when return air dampers are being closed and supply air blower is in operation. The extraction fans run when outdoor air dampers are at least 50% open (adjustable). It is also overload protected. A gravity exhaust damper is supplied with this option to prevent air from entering the unit during shutdown.The power exhaust fans have been size to exhaust 50% of the nominal air flow of the unit.
