Corrosion protection for Compact air coolers


Coil Defender – Alternative corrosion protection for Compact air coolers

In food processing and storage, there are many different applications with as many combinations of aggressive substances in the ambient air that have to be considered when selecting the appropriate cooling technology. With the Coil Defender coating, Güntner offers an attractive alternative especially for applications in which the atmosphere is slightly aggressive, requiring a corrosion-resistant unit, but in which stainless steel would be over the top.

Your advantages at a glance

  • Hygiene-certified design in accordance with HACCP
  • Evenly applied coating with high thermal conductivity
  • Coated standard materials instead of expensive stainless steel tubes with epoxy-coated fins
  • Food-safe coating
  • 3 years of warranty!


Typical applications

Be it the processing of meat or fish, the storage of citrus fruit or stopping fermentation: What you need is an air cooler that operates in a reliable way – a heat exchanger with Coil Defender is the right choice here.


Food-safe coating, certified design

The Coil Defender coating is not only food-safe, but also resistant against common water-based cleaning agents.
Moreover, all air coolers of the Compact product line are certified by the independent body TÜV SÜD in accordance with the HACCP hygiene concept, thus offering you many advantages.

Completely coated standard materials

The heat exchanger consists of the standard material combination of copper tubes and aluminium fins. The Coil Defender Coating is applied evenly to the entire coil to ensure that there is no chance of any aggressive substances attacking it. In combination with the powder-coated casing, you get a completely protected unit.

Easy and fast design with the GPC

With the Güntner Product Configurator (GPC), you have the possibility to design the units you need in a quick and easy way, adapting them to your requirements. The Coil Defender option will be indicated automatically – you just have to give it a click.

Economically attractive alternative

The Coil Defender is an excellent alternative in those applications where the atmospheric composition does not require a heat exchanger made of stainless steel tubes and epoxy-coated fins.

The special Plus

We offer you a 3-year warranty on all units of the Compact product line, including the units with Coil Defender coating!

Available for all Compact air coolers

Depending on the kind of application, there are different requirements that the air coolers have to fulfil. Therefore, the Coil Defender Coating is available not only for the SLIM Compact product family with their flat design, but also for the universal solution for commercial refrigeration, the CUBIC Compact, and the DUAL Compact which is especially appropriate for working rooms.
