Prism's advanced multistage pretreatment systems are perfectly suited for both batch and continuous operation. These perform a through cleaning of all metal parts to be processed, and provide superior corrosion protection. Reducing effluent load uses cascaded ranges for water conservation, there. Clean bath and bath life is achieved by incorporating continuous oil separation and phosphate sludge separation system. Flexible nozzles ensure easy adjustment of spray direction and air pocket direction. Quick release pipe coupling and nozzles aid easy maintenance.

Advanced F.R.P/S.S. systems are compatible with all solutions and therefore off high chemical resistance and prevention of mechanical damages, CHROME Free post pretreatment (de-ionized water rinse) facilitates better sealing.Water treatment plants are effectively employed to treat the effluent and they conform to local statuary requirements.
 
Prism offers CLEMCO’S grit blasting facility/grit recovery systems for removal of heavy MIL SCALE and rust, especially in H.R steel sections, for effective surface preparation prior to painting/powder coating with or without post dip/spray pretreatment.

Surface preparation can be done by multistage operations .The most commonly used multistage operations are 3 stage and 5 stage by following ways.
 

1. Spray Pre-Treatment: This method of pretreatment employs the use of an electrical motor to power a pump providing pressurized solution through a heating coil to a hose and hand held wand assembly.

The heat is providing by oil or gas fired burner to a heating coil that is part of this stand-alone system.

Advantages -> Can be used for large and bulk components.
 
Disadvantages -> Skilled labors required for troubleshooting.


                

2. Dip Pre-Treatment: This process is dipped process, which employs one or more tanks That holds solution in which the parts are batched or process dipped continuously via overhead conveyor. This is basically preferred for batch process .

Advantages ->Simple to maintain, low capital cost, prolonged chemical contact time is possible complete contact with chemical solution and more flexible chemistries can be used.
 
Disadvantages-> Suits for batch process only.

 
       

3. Re-circulating spray process: This the most preferred pretreatment process used in the industry as it has better efficiency. This process reduces the waste management systems.

Advantages -> High efficiency levels of cleaning and conversion possible. Recirculation keeps the part in contact with fresh solution. Process time can be shortened energy saving is possible.
 
Disadvantages -> High capital and maintenance cost. Trouble shooting techniques requires expertise.

Heating Systems

Some of the heating methods available are immersion tanks, plate coils and plate and frame heat exchangers. Immersion tubes are long tubes along the floor area of the tank. Heat transfer takes place along the surface of the tubes. The fuels used for this type of heat source are propane, LPG, HSD and LSD. The plate coils are very cost effective if there is an existing steams source available in the plant. These are immersed inside the tank and the steam is sent thro the tubes.

SCADA is the abbreviation for Supervisory Control And Data Acquisition. It generally refers to an   industrial control system which is meant to function across a wide area with an autonomous Remote Terminal Unit (RTU).

The precise definition of SCADA has been muddied somewhat by newer telecommunications technology, enabling reliable, low latency, high speed communications over wide areas, and a tendency by popular media to mistakenly refer to all Industrial Control Systems as SCADA. Despite this confusion, a SCADA system is expected to have open loop controls (meaning that a human operator watches near real time data and issues commands).By comparison, a Distributed control system (DCS) is expected to have closed loop controls (meaning that real-time loop data is applied directly to an industrial controller without human intervention). These differences are primarily design philosophies, not mandates of definition.

The supervisory control system is a system that sends commands to a real-time control system to control a process that is external to the SCADA system (i.e. a computer, by itself, is not a SCADA system even though it controls its own power consumption and cooling). This implies that the system coordinates, but does not control processes in real time, as there is a separate or integrated real-time automated control system that can respond quickly enough to compensate for process changes within the time constants of the process. The process can be industrial, infrastructure or facility based as described below: Pre-treatment plants

  • Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.
  • Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, and large communication systems.
  • Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations. They monitor and control HVAC, access, and energy consumption.

 Prism has installed many pre treatment plants for powder coating plants and painting plants worldwide such as egypt,Russia,Qatar,Bahrain,Oman,Algeria,morocco,Israel,Saudi arabia,Tunisia,Kenya,Nigeria,Thailand,Vietnam,Australia,united states,Germany,France,japan,china,mexico,Brazil,Argentina,Peru,Jordan,Iran,Switzerland,Austria,India,Indonesia,Philippines,Singapore,Myanmar,UAE/dubai etc.
