CRESCENT TECHNOLOGIES PVT. LTD.

Sector 8, Noida, Delhi

conveyorised ovens like gas fired ovens, gas fired industrial ovens, electric conveyor ovens, conveyorised electric ovens are best suited to industries where continuous drying heating roasting bakingcuring etc. Of materials and components is required. Wire mesh belt canvas belt slat conveyor is provided for the continuous transportation of materials components through the oven. The ovens can be provided with variable speed and different heating zones having individual control to cater the user's need.

Powder Coating Plants 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. The Powder Coating Plant configuration depends upon sizes and shapes of the articles, coating quality required in conjunction with the colour change intervals.

A thorough material pretreatment is the fundamental prerequisite of any high quality coating. Wet or Dry pretreatment, depends on the material to be coated. Crescent provides solutions for degreasing, phosphating, grinding, shot blasting or ionizing on the turnkey basis with requisite Material Handling and Automation.

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

Inclined plates settlers or Lamella clarifiers are used in the Chemicals and waste water treatment industries to separate solids from liquids in effluent streams. The Clarifier can also be supplied with Filter Press in series to make cake of the effluents for safe/easy disposals.

Used to further separate oil from the collected skimmed oil and water. Chemical is returned back to main tank and only oil is collected-improves quality of De-greasing.

Powder Coating Plants 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).

The Powder Coating Plant configuration depends upon sizes and shapes of the articles, coating quality required in conjunction with the colour change intervals. Our specialists in surface coatings have individual answers and concepts for all these requirements. Conveyorised powder coating plants are specially designed suitable for powder coating of high volumes, small & large sizes of components. The conveyorised applications give better and uniform coating qualities with better process controls. These plants can be supplied with automated painting guns ondr reciprocators etc.

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.

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.

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.

Crescent the 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.

Crescent spray 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. Crescent range 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. Crescent Booths can be provided with pressurization for dust proofing, Manual/ Automatic Painting applicators like Auto Guns, Discs and Bells or Robotic Painting. Benefits:-

• Most efficient way of containing over sprayed paint.
• Restricts paint over spray to a specified area.
• Provides optimum air velocity to exhaust the over spray without affection spraying efficiency.
• Provides for maximum operator comfort and reduces attendant health hazards.
• Safe: minimizes risk of fire due to solvent vapours and over spray deposits.

Crescent Ovens are designed to consume low power/Fuel with a uniform temperature throughout the Oven. Various safety features like Blower/Heat Source interlock, Pressure release mechanisms and Auto Shut-offs are provided to make these ovens fully safe. Crescent ovens can be heated by :

1. Electric Heaters Normally for Small Batch Type Applications.
2. Oil Fired HSD/LDO- With air to Air Heat Exchangers and Thermal Oil Heating.
3. Gas Fired- CNG / PNG/ LPG /Propane Normally used for large ovens . The Gas fired ovens can bea) Direct Firedb) In-Direct Fired.
4. IR Heated normally used for Plastic/ABS curing in a Tunnel type Oven.

Conveyors ensures an optimized, automated flow of material, resulting in increased productivity, lesser space & manpower requirements. Material handling equipments are very critical in painting lines. Crescent offers following types of conveying systems used for material movement in the painting lines.

• Manual push pull monorail conveyor For Batch Type/Heavy parts movements.
• Overhead electric hoist system used in dip pre-treatment.
• Fully automatic PLC based Transporter system with flight bars/Cages used in Dip PT/ED Coatings.
• Belt /Wire-mesh surface conveyor For Tunnel Ovens.
• Enclosed track continuous power conveyors Most Common in Painting applications. Heavy duty I- beam continuous power conveyor
