Water Drying Oven in Kolkata, West Bengal
SEW Surface Coating Pvt. Ltd. designs, manufactures and installs water drying ovens (WDO) for manufacturers in Kolkata, West Bengal. Every plant is built at our own works in Pune, Maharashtra, then erected and commissioned at your site in Kolkata.
After pretreatment, components must be completely dry before they enter the powder coating or painting booth. A water drying oven is an enclosed, insulated chamber with air-circulating blowers and a heating system that removes all moisture quickly and evenly. We build it to match your pretreatment plant, conveyor and production rate.
- In-Line, Batch & Conveyorised
- Camel Back for Low Heat Loss
- Matched to Pretreatment
- Supplied across Kolkata
Water Drying Ovens for Kolkata's Manufacturing Industry
Kolkata and Howrah are eastern India's historic engineering centre, with foundries, wagon builders, electrical makers and fabricators. Newer industrial parks at Dankuni, Kalyani, Uluberia and Falta SEZ, along with Durgapur and Haldia, extend the region's base.
In Kolkata, demand for water drying ovens comes mainly from railway and heavy-engineering suppliers, electrical and panel makers and engineering and fabrication units. Water left in seams, holes and folds after the final rinse causes blistering, pin-holes and poor adhesion once the part is coated. A correctly sized drying oven removes that moisture completely, so every part reaches the coating booth dry and at a steady temperature.
Railway, electrical and engineering suppliers here need robust finishing. Kolkata is about 1,900 km from our Pune works and plants are delivered by road.
Types of Water Drying Ovens We Supply in Kolkata
In-Line With Dip Pretreatment
A tank-type oven placed in line with the dip pretreatment tanks. The same hoist or transporter that dips the basket loads it into the oven.
- Hoist or wagon puts the basket in and takes it out
- Tank type construction
- Pneumatic or hydraulic doors
Best for: Dip pretreatment plants with hoist or transporter.
Batch Type Water Drying Oven
After pretreatment, components are loaded on a trolley and the trolley is pushed into the oven to dry off the water.
Best for: Batch plants, large components and lower volumes.
Conveyorised Conventional WDO
The conveyor carries articles through the insulated chamber for a set time and brings them out continuously, dry and ready for coating.
Best for: Spray pretreatment lines feeding a conveyorised coating booth.
Conveyorised Camel Back WDO
Works like a conveyorised oven, but the article entry and exit are cut out parallel to the ground so hot air stays inside and heat loss is reduced.
Best for: Continuous lines where fuel saving matters.
Where the Water Drying Oven Fits in Your Line
The water drying oven sits between pretreatment and the coating booth:
- PretreatmentDegreasing, de-rusting, phosphating and rinses.
- DM Water RinseFinal rinse leaves a clean, salt-free surface.
- Water Drying OvenHot air circulation removes all moisture.
- Coating BoothDry parts move on to powder or liquid coating.
- Curing OvenThe coating is baked to its final finish.
Oven temperature, size and residence time are calculated from your component weight, conveyor speed and the fuel available at your site.
Equipment Supplied With the Water Drying Oven
Pretreatment Plant
Dip or spray pretreatment cleans and phosphates the metal surface so the coating adheres well and resists corrosion.
Transporter System
PLC-controlled transporter that moves jobs through the tanks on a programmed cycle, giving priority to critical tanks.
Powder Coating Booth
Electrostatic powder booth with mono-cyclone or multi-cyclone recovery and after filter unit.
Oil Skimmer
Continuously removes floating oil from the degreasing tank, so the chemical lasts longer and parts come out cleaner.
Sludge Separator
Separates phosphate sludge from the bath to keep the process stable and cut tank-cleaning downtime.
Air Agitator
Keeps the bath moving for even temperature and chemical concentration around every component.

Water Drying Oven in Kolkata – Frequently Asked Questions
Do you supply water drying ovens in Kolkata?
Yes. SEW Surface Coating Pvt. Ltd. manufactures water drying ovens at its factory in Pune and supplies, erects and commissions them for customers across Kolkata, West Bengal.
Why is a water drying oven needed after pretreatment?
Any water left on the component after the final rinse causes blistering, pin-holes and poor adhesion once it is coated. The water drying oven removes all moisture so parts enter the coating booth completely dry.
Which water drying oven suits a dip pretreatment plant?
An in-line, tank-type oven placed after the last dip tank is the usual choice, because the same hoist or transporter loads it. For trolley-based plants a batch type oven is used.
What is a camel back oven?
It is a conveyorised oven whose article entry and exit are cut out parallel to the ground, so hot air stays inside the chamber. This reduces heat loss and fuel consumption.
Can you supply the pretreatment plant with the oven?
Yes. We supply the complete pretreatment plant, water drying oven, coating booth and curing oven as one line.
How is the plant delivered and installed in Kolkata?
The plant is fabricated at our Pune works, about 1,900 km from Kolkata by road. It is dispatched to your site, where our team erects and commissions it and carries out trial runs.
