Wilk Graphite

COIDAN Graphite works in close collaboration with Wilk-Graphite GmbH to provide high quality, cost-effective graphite heat exchangers for its UK based customers. As well as being able to supply Wilk products, COIDAN can provide all the pre- and post-sales technical advice and guidance you might need in relation to them. We’re able to offer a range of shell and tube heat exchangers, as well as modular block and cubic block heat exchangers, all of which are competitively priced. For full details and specifications, please visit the COIDAN Graphite website.

Titan Pharmaceutical Condensors

The Tantalum Pharmaceutical Condenser has been developed in response the various regulations laid down by a number of governing bodies, including the FDA and EPA. Today’s condensers need to be contamination-proof, corrosion-proof, fully drainable, compatible with silicone based heat transfer fluids, rugged and maintenance free. Tantalum ticks all these boxes. These condensers have been built to an extremely durable, fully welded design, giving many years of outstanding performance without downtime. Although initially more costly than graphite models, condensers made from tantalum are far more cost-effective in the longer term, since graphite is prone to mechanical damage and breakdown (which results in higher maintenance costs, scrapped products and lost production time). You can find out more about the benefits of tantalum by visiting the COIDAN Graphite website.

Titan Steel Pickling

Through our partnership with Titan we’re able to offer a full line of standard and customised shell and tube heat exchangers for indirect steam heating of pickle baths. The range can be broken down into two distinct categories:

  • Zirconium Heat Exchangers – for steel pickling with sulphuric acid. Zirconium is highly corrosion-resistant and offers greater heat transfer properties than traditional materials (graphite). A fully welded design prevents breakages during handling, installation and operation, ensuring a longer service life.
  • Tantalum Shell & Tube Heat Exchangers – for steel pickling with hydrochloric acid. Tantalum is one of the most inert materials for complete corrosion resistance during pickling processes. It offers outstanding heat transfer properties and higher pressure handling capabilities than traditional materials (graphite).

Titan Chemical Processing

Titan is also a leading producer of highly corrosion resistant process vessels and heat exchangers for use in the chemical, petrochemical and pharmaceutical industries. They use a range of reactive metals, including tantalum, zirconium, titanium, niobium and high nickel alloys such as hastelloy. Process equipment made from these materials may be used to handle extremely corrosive fluids and will last for decades in doing so.  COIDAN are able to offer a product line that encompasses:

  • Columns
  • Evaporators
  • Reactors
  • Pipework
  • Heat Exchangers

Arc Furnace Electrodes

COIDAN offer a comprehensive selection of graphite electrodes measuring anywhere between 75mm and 610mm in diameter. These are suitable for a wide variety of applications across a multitude of industrial sectors.

  • SHP Grade Electrodes – suitable for use in high power electric arc furnace and ultra-high power ladle furnace applications.
  • HP Grade Electrodes – suitable for high power ladle furnace, foundry and fused mineral applications.

Should you require any help or advice in choosing the right electrode for your individual requirements, please give us a call or submit your furnace details via our website.

Carbon Gouging Rods

COIDAN offer a selection of carbon gouging rods used for metal removal (generally welding defects, excess welds and foundry risers from cast products). Precision machined using state-of-the-art manufacturing equipment, our carbon rods are amongst the very best in the industry, offering fast removal rates and low power consumption. 

  • Pointed Copper-Coated Gouging Carbon Rods – for cutting, welding, defects removal, hole making, welding inspection.
  • Flat Gouging Carbon Rods - for close tolerance metal removal.
  • Jointed Gouging Carbon Rods – for manual and automatic operations where high removal rates are required.
