Batch Control

Liquid dosing, pumping, metering, mixing and blending are required in various process. Due to fast-changing demands in today's market, business environment changes faster than ever. Manufacturers need to be able to respond quickly to changing demands while ensure product quality.

PVN Engineering has the expertise to provide customers with cost effective solutions for their batch control applications. Our solution results in:

  • Efficiency ImprovementBatch
  • Product Consistency and Quality
  • Operation Precision
  • Production Flexibility
  • Human Error Minimization
  • Waste Reduction
  • Production time Optimization

System components may include:

  • Sensors
  • Instrumentations 
  • Actuators
  • Batch Controller
  • Human Machine Interface
  • Program

The batch control system can be as simple as a stand-alone single-function preset controller controlling a pump and a automated valve for filling or as elaborate as a PLC based batching system, offering both control & reporting functions. We can fabricate skid mounted modular PLC systems for easy integration that do not lead to costly plant interruption.


Pollution Control

One of the biggest challenges manufacturers face is finding new techniques to prevent the creation of additional air pollution. With rising problems of air pollution concerning the standard of living, government announces new regulations, standards, enforcement as well as community pressure in attempt to control the air quality. At PVN, we develop a complete solution to your pollution control. 

Tank Technology

PVN offers various solutions for all types of tanks; whether it is storage tank, IBC, totes, mixing tank, process tanks, and etc. Our solutions include:

Gas Detection System

Gases and vapours can be dangerous. There are three main dangers which can pose by the presence or absences of gases:

  • Ex - Risk of Explosion by flammable gas
  • Tox - Risk of poisoning by toxic gas. If gases do not exist in their familiar and respirable atmospheric composition, safe breathing might be affected


Our gas detection system can detect:

Toxic Gas Toxic Gas and Vapours
Ammonia, Carbon Monoxide, Carbon Dioxide, Chlorine, Hydrogen Sulfide, Hydrogen, Amines, Hydrides, Mercaptanes, Organic Vapours, Acidic Compounds,... 
Flammable Gas Flammable Gas and Vapours
Ethanol, Methane, Propane, Ethylene, n-Octane, n-Butane, n-Pentane, n-Heptane, n-Octane, Cyclohexane, Ethane, Toluene, Benzene, Ethyl Chloride,...

Coating Technology

Technology for Precise Application for Viscous and Non-Viscous Coating

For the coating application, the following problems are regularly met.

- Uneven application of coating

- Waste of coatly coatings due to over-application

- Cannot control quality of the product due to inefficient coating application


When using our coating solution, we are able to:

  • Reduce product scraps caused by over- or under-application of coatings
  • Reduce the use of costly chemical by applying only the proper volume directly on the targeted area
  • Increase production speed (fast cycling up to 15,000 cycles per minute) to keep pace with fast line speeds
  • Reduce set-up and changeover time because one spray set-up can cover wide range of flow rates
  • Achieve very low flow rate 
  • Hydraulic type is available - reduce the use of compressed air and reduce misting and overspraying

Where can our coating solution be used?

We offer a wide range of products to meet the demands of various applications including:

  • Coating
  • Flavoring
  • Oil application
  • Release agents/ lubricants
  • Resins/ Wax
  • Thick slurries

Typical Solutions

  • Precise Spray Control
    For precise chemical application which the chemical volume can be controlled. This reduces the use of costly chemical, eliminating the waste, improving product quality and increasing production
  • Conveyor Coating
    For coating liquid to the moving products/ parts on the conveyor. Headers and manifolds can be supplied. They can be configured as air atomized or hydraulic, material can be chosen and the length can be custom-made. Our nozzles feature the capacity to fine tune flow rate, drop size and spray shape. The spraying of the coating can be controlled on-off according the presence of the coated surface.
  • Coating Header
    We offer wide range of headers and manifolds customized to fit your requirement. Various types of headers design are available: channel, pipe-in-pipe, compact, sanitary and heated to use with both hydraulic and air atomizing nozzles. Header length, number of zones, nozzles type and nozzle spacing are all custom-made. 
  • Application-specific header
    Application-specific header for the following applications are available: food coatings, oils and lubricants, wax and resins, mold-inhibitors, anti-microbials and more
