Ditmer Trading & Consulting BV developed together with Alpha Robotica & Franken Techniek two semi automatic flow coating machines for wet enameling the in- & outside of complex shaped heat exchangers.
Depending upon the annual production volume, it might be interesting to reduce labor cost by integrating all equipment of an enameling plant for water heaters and/or solar boilers.
Such integration may be done with traditional monorail conveyors in combination with automatic transfer devices, like on the picture below.
Alternatively a so-called power & free conveyor system may be used.
This conveyor type consist of two conveyor tracks above each other.
On the lower level free cars may run, while via the power chain at the upper level the free cars may be (dis)connected and transported.
Nowadays there are P+F systems, which thanks to a very special transfer system even include the transport of products within the enameling furnace.
DTC may assist with the evaluation, which solution is most suitable for your vitreous enameling project.
In January 2003 Nordson Benelux B.V. delivered upon request by Senter together with a consortium of four other Dutch companies, a complete boiler enameling plant based on Ferro’s electrostatic dry powder enamel technology to Leov Company in Veles, Macedonia in order to replace their environmental unfriendly galvanizing process.

Case story about the definition & implementation of an industrial enameling plant for electrical water heaters
An OEM of electrical water heaters aimed to reduce the cost price of their products, while improving its lifetime.
Wished to switch the watertank substrate from copper to mild steel with porcelain enamel coating.
What is a porcelain enamel coating ?
Porcelain enamel is a durable glass alike coating, which is fused on a metal substrate. More >>
How about corrosion resistance ?
Studies showed that the expected lifetime of enameled boilers is much longer then alternative coatings. More >>
Is our tank suitable for powder enameling ?
Tanks should be made of mild steel, which is suitable for enameling, and constructed in accordance with ISO 4753-3. More >>
What type of equipment is required ?
A boiler enameling plant has typically three process steps; metal pretreament, enamel application and firing. More >>
How much cost a boiler enameling plant?
The required capital investment for a modern boiler enameling plant depends on a variety of aspects.More >>
How can DTC assist ?
DTC may provide independent advice & support during all stages of your enameling plant project. More >>
Porcelain enamel provide a robust “glass-lining” to warm water tanks to protection them against corrosion caused by boiling water and is therefore used by leading manufacturers of electrical boilers, solar water heaters and/or other warm water containing applications.
Enameled mild steel tanks are typically used to eliminate expensive water tanks, made of copper and/or stainless steel, which are less suitable for operation in area’s with “poor water”.
|Porcelain enamel is used by leading manufacturers of electric boilers, solar water heater and/or water storage tanks worldwide to protect their tanks against corrosion.
This website describe the available technologies, plant concepts & equipment for applying a durable & cost effective porcelain enamel coating inside various types of hot water tanks.

Boiler enameling plant layouts can be projected with either conveyorized or stand alone shortblasting & powder application equipment.
This conveyorized solution is called “online” and the other stand-alone solution “offline”.
See below the schematic plant layouts for both solutions. Please click on the thumbs to see the full size layouts.
Online boiler enameling plants are typically used for large production volumes of relative simple hot water tanks.
Its main benefit is a high level of integration, which eliminate the need for manual transfer between the various process stages.
Below some pictures of various online boiler enameling equipment, such as :
shotblaster / powder application / automatic transfer device / furnace.
Please click on the thumbs to see the full size pictures.
Offline solutions are typically chosen for relative low production volumes or
complex product shapes.
This solution is cheaper and is also suitable for boilers, which can’t be clamped in the centering system of an online solution.

When you are consider installing a new porcelain enameling factory, altering the enameling process and/or new equipment of your existing enameling plant or in/outsourcing your coating operation, you most probably want to determine your Return-On-Investment by comparing your actual versus future enameling cost.
