Fin Technology

Our Fin Materials & Coatings

• Plain

  As standard, our coils are manufactured from the highest quality plain aluminium fin stock to ensure that we get maximum secondary surface resulting in improved performance.

  The plain aluminium fin stock is the most economical fin material we offer and tends to be used on around 50% of the coils we manufacture. It works well with heat transfer from the pipe to the extents of the fin block and has been used in refrigeration for well over a century.

  We also offer a plain copper fin which gives the best heat transfer possible when used with our copper tubing. The plain copper fin option is usually selected for saline/coast environments as this lasts much better than plain or coated fin in these harsh conditions. We also offer a special electro-tin finish to our copper fin blocks.

• Coated Fins

  Aside from our plain aluminium or copper fin material, Beehive can also produce coils using fins with several different standard pre-coated finishes to suit a variety of requirements.

  The vinyl coated (epoxy) 'gold' finish aluminium fin is excellent for additional protection to coil fins if the unit is used in a mild chlorine environment or is normally suggested if the coils are positioned in direct sunlight on an outside unit for example.

  Alternatively, we can also offer a black coated finish to our aluminium fin material which is generally used to help hide the coil block in ceiling mounted units or chilled beam systems and whilst helping to conceal the coil itself, this also adds further protection to the aluminium fins.

• Hydrophilic Coated Fins

  Beehive also offer a hydrophilic coated 'blue' aluminium fin which greatly assists moisture run-off from fin blocks.

  Our hydrophilic fin is generally used in low temperature applications and has been developed to assist with moisture run-off from coil fin blocks. This advanced material can increase the time between defrosts or enable shorter defrost periods by slowing down the process of ice build-up in the fin area and comes with a blue tint to make identification simple.

• Blygold® Corrosion Protection

  Adding Blygold® Corrosion Protection coatings to our coils can help reduce energy loss and prevent breakdown of your climate system.

  Blygold® UK offer their PoluAL XT coating developed for the protection of air-cooled heat exchangers and also offer other products to help protect coils situated in harsh environments which are vulnerable to severe corrosion.

  You can purchase coils from Beehive with a Blygold® coating included (just ask at quoting stage), ship your completed coil to Blygold® directly or they can also coat your new coil on site, depending on its location.

  Beehive are in no way affiliated with Blygold® or Blygold® UK and only recommend their products based on past experience and known customer satisfaction.

• Heresite® Protective Coating

  We are pleased to be able to offer our products with Heresite® Protective Coatings included to help protect units situated in harsh and/or marine environments.

  Beehive offers Heresite® P-413 baked phenolic epoxy coating applied here in the UK. This is the first HVAC-R coil and radiator coating that meets ISO 12944-9 standard for severe offshore marine environments.

  Heresite® state that this coating can significantly extend the service life of HVAC-R equipment if properly maintained with thermal loss, as a result of adding this coating, estimated at below 1% as indicated by process equipment OEMs.
