Ventilation Automatic Control System

A complete range of ventilation solutions for the paper industry. Our know-how in air-technology is the basis of effective solutions for new machines as well as existing systems.

With properly designed air systems, a significant reduction in energy costs and an increase in productivity are feasible. Effective air systems also lead to improvements in availability and quality. Moreover, they are elementary for conservation of building structure. Our products are designed for reducing energy costs and optimizing the production process and quality.

One of the major barriers to implementing highly efficient HVAC systems is the installation of oversized systems that result in inefficient part-load most of the time. In order to break the vicious circle created by this conventional practice, training workshops to upgrade professional knowledge will be necessary. Furthermore, well designed demonstration building projects that are equipped with highly efficient HVAC systems and show a proven records of energy saving and good thermal comfort performance, will be a good catalyst.

Product Features

Strong environmental adaptability: Iron Slurry Analyzer can adapt to the harsh industrial site environment.

Highly corrosive environment: The probe is made of corrosion-resistant materials and can adapt to most corrosive environments such as strong alkalis.

There are no special requirements for the composition of the materials to be measured: Ventilation Control System is not affected by bubbles; Mine Ventilation System is low affected by large particles; Mine Control System is not affected by magnetic interference.

The detection range of particle size is wide: the maximum size range of 60 percentage points can be detected, and the minimum size range of 20 percentage points can be detected.

The size fraction span is large: The particle size analyzer measurement can be achieved in the diameter of the grain between 20μm to 1000μm.
