The Control Panels are very critical in paint-shops. The operations, efficiency and Safety of the Paint-shop depend on the Control panel design. Crescent provides following type of Panels.

1. The conventional type of panels with contactors and relays most commonly used in the industry. We provide all the safety like HRC fuses/MCB and Relay protection. The electric circuits are inter locked/connected for small automation. Mimics may also be provided on the panels for better process display and Controls.
2. PLC based control panels which perform control functions through modular input and output (I/O) modules. The modularity of PLC allows the user to combine generic I/O modules with a suitable controller to form a control system specific to his needs.
   Input devices and output devices of the process are connected to the PLC and the control program is entered into the PLC memory.

3. Touch Screen Panels :Crescent plants can be provided with touch screen Control panels where as the complete panel and its process details can be operated / controlled from the touch screen provided on the PLC panel . With these plans plant process can be automated to save on fuel and energy.

SCADA Based Control Panels :Crescent now offers SCADA- Supervisory Controls and Data Aquision based control Panels for better controls of the Plant . The supervisor or the Paintshop manager can control the complete plant from a remote location. Different datas can be collected and the reports can be obtained as desired for better process controls, low maintenance and automation of the system. Different reports like current of various critical motors, Conveyor speed and oven/booth temperatures at a given point of time, fuel consumption with productivity etc. can be tabulated with these panels.

Advantages of SCADA

• Automated Centralized Control data logging and reporting with Alarm Control systems.
• Lesser maintenance and user friendly Mimic Process visualization
• Output derivations for timely predictive maintenance avoiding break-down times.

Crescent offers high RPMs Electrostatic Discs for Automatic Paint Applications. The Electrostatic disc tends to throw the paint away when the paint passes through the charged disc, forming much finer thin fog. The lost paints are sucked back to the work piece due to electrostatic effect and the over spraying phenomenon is thus minimized.

Applications : Bicycle Parts, Computer Cabinets, Wooden items, small tubular components and manymore.

Powder Coatingis an advanced environment friendly painting method, which obtains paint film by putting powder paints to an object to be painted and by melting with the use of Powder Curing Oven. It is the most exciting finishing method introduced in past 100 years. Powder Coating offers significant performance advantages with reduced costs. It also meets environment regulations.(No VOC emission, no paint sludge disposal)

Crescent provides dip chemical treatment with PLC based transportation or electrically operated over-head hoist for material movement

Crescent Spray PT Lines are used for large painting lines and automotive components; it gives fully automatic operation for on-line surface pre-treatment and also gives excellent and uniform results.

Sand/short Blasting is normally provided for casting and forging industries. It helps in reducing the water pollution considerably.

Liquid painting is used to give high quality asthetic finishes and can be applied on metal, plastic and wood. High quality, multilayered paints can be applied in these virtually dust free Crescent plant designs.
There are various Liquid Painting processes meant for different substrates, shape of components based on ultimate Finish and Quality requirements.

The following can be the general classification:

1. Multi Layers (Coats) Liquid Painting Lines:

   The most common liquid painting line usesWet-on WetorBake-on-Bake 2 or 3 coats of paints one over the other. A typical line may be Primer coat followed by Top/Metallic coat and further followed by Clear/Lacquer coat. This is done after adequate surface preparation.The paint application system may be HVLP, Electrostatic, Airless, Bells or Discs depending on the shape of the components, production volumes , paint consumption and the type of paint. The application process can be automated like Auto Guns on Reciprocators or Painting Robots .

Industrial painting robots are capable of transforming both the application and the work environment.

Robotic painting or coating produces top quality results. Once properly programmed, an industrial painting robot can apply material without leaving behind any drips, inconsistencies, overspray, etc. Paint and/or coating are applied precisely and consistently.

Fume Exhaust cum Scrubber :Fume Exhaust isprovided to protect men/machines/materials in the plants from hazardous gases and fumes and Pollution Controls. The Exhaust can be directly feed to environment or pass through Water Scrubber based on the Hazardous nature of the fumes.

We incorporate all the possible safety measures in our offered plants and are also supplying the required infrastructure for the same. Major safety aspects taken into consideration are :

• Fire fighting systems We offer complete fire fighting solutions for paint shops. This includes water sprinkler and CO2 flooding system. Water sprinkler system consists of fire/smoke sensors. Main types of systems offered in this category are :

This comprises of gas concentration level (LEL) monitors with alarm systems. A fully customized panel can be installed which can handle any number of channels, can provide any number and combination of relay alarm devices, repeater panels, zone annuciators etc. The monitor can provide the functions of signal processing, alarm generation, battery back-up power supply etc. all in a weather proof enclosure. The sensor head can be installed on a mounting bracket in the area of interest .

A control output is available for directly driving external horn, hooter, flasher, exhaust fan, Shut off valve, voice alarms, auto-dialers etc.

Crescentthe most modern electrostatic Powder Coating Spray system is design of new Millennium and is made out of the Hi-tech, indigenous quality components. Multiple safety measures are incorporated in the system to make it absolutely safe and trouble free.

• State-of-the-art 100kV integrated spray gun.

• Pluggable PCBs to ease serviceability
• Higher transfer efficiency
• No Farradys cage effect.
• More than 1000 installations nationwide.

The contoured design of the Alfa Series Cyclone Type Booths ensures uniform air flow throughout the booth cross-section. Absence of dead pockets ensures easy cleaning and the charged powder surrounds the article uniformly resulting in higher transfer efficiency.


Crescent Booths are known for:

• Optimum Powder Recovery
• Easy Cleaning
• Faster Colour Change
• Can be fitted with material handling system suitable to the customer requirement such as loose track, trolley or the overhead conveyor.
• Powder recovery system: single or Multi cyclone type.

Crescentspray painting booths are widely accepted in all type of liquid spraying application. Crescent liquid spray booths are meant for low power consumption and high efficiency.

Crescentrange of spray painting booths includes water curtain type with water pump, and dry type without pump, down draft and side draft type. We can design special booths depending on the requirement and application to give the maximum output and optimum utilization.
