Coating Solutions for Radiator Tubes and Aluminium Fins

NANOKOTE also manufactures coatings that are used on the external bodies of trucks (prime movers and tailers) and trains.

In the case of trucks, thousands of trailers and prime movers have been coated in Canada and the United States to assist in combating the harsh corrosive environment created by the de-icing of roads. Both Aluminum and Stainless Steel have been successfully coated in these environments and been able to withstand ongoing Canadian and North American winters.

Coatings are an important part of radiator and heat exchanger performance for vehicles that demand a higher level of protection (for example mining vehicles, trucks, trains, heavy machinery). They act as a barrier to protect the metal from corrosion and heat while also promoting efficient heat transfer. Different types of coatings can provide different levels of protection and benefits, so it’s important to choose the right type for your specific radiator needs.

Common coatings for radiators include epoxy, anodizing, powder coating, and chromizing. Epoxy coatings are used for superior corrosion resistance and heat insulation, while anodizing provides a strong wear-resistant coating with excellent electrical properties. Powder coating is a popular choice for decorative purposes, and chromizing

provides improved surface hardness combined with good corrosion resistance. With advancements in technology, coatings can now be tailored to meet specific requirements such as faster drying times, low smoke emissions, or UV resistance. It’s important to work with experienced professionals to choose the perfect coating for your radiator needs.

Heat exchanger coatings are an important component of heat transfer systems because they help to improve the durability, efficiency, and overall performance of the equipment. Coatings can be applied to the surface of heat exchangers in order to provide protection against corrosion, fouling, and erosion. Corrosion can occur when the heat exchanger is exposed to a corrosive environment, leading to damage and reduced efficiency. Fouling can occur when sediment, dirt, and other materials

build up on the surface of the heat exchanger, leading to decreased heat transfer and increased energy costs. Erosion can occur when particles, such as sand, dust, or other materials, impact the heat exchanger surface at high velocities, leading to wear and tear.

Heat exchanger coatings can be applied through various methods, including spraying, dipping, and electroplating. These coatings are typically made from materials such as polymers, ceramics, and metals, and can provide a range of benefits. For example, polymer coatings can provide excellent corrosion protection, while ceramic coatings can provide excellent thermal resistance and insulation. Metal coatings can provide wear resistance and can also be used to restore damaged or worn surfaces. The type of coating used will depend on the specific needs of the heat transfer system and the conditions in which the heat exchanger is used.

Overall, by providing heat exchangers with effective coatings, businesses can improve equipment performance and reliability, thereby reducing energy costs and improving their bottom line.

Train bodies are also coated with NANOKOTE coatings to permanently protect them against graffiti. Kiwi Rail in New Zealand are leading this.
