AHU RENOVATION Air handling units are used for the offshore and marine industry and are crucial installations for creating an optimal climate in all kinds of environments. These installations provide the air we breathe and control the temperature and humidity in the places we live and work. It is clear that these ‘lungs’ must be kept in optimal condition. This will result in an optimal indoor climate, controlled energy consumption and a long lifetime of this expensive equipment.

The air handling units are specially designed to be compact and allow for fitting in the often limited space of ships, yachts and offshore modules. The fans are made of high-quality materials to withstand the extreme sea climate conditions.

The air handling unit is made of the most sturdy materials to withstand extreme cold or hot and humid air conditions, the salt sea air and the extreme environments.

Application With the huge volumes of outside air which pass an average air supply installation, comes the threat of equipment degradation. While installations might look like they are in good condition from the outside, inside severe problems can be found. Corrosion can be found in almost every air handling unit due to the aggressive pollutants in outside air that are even able to pass through high quality filters. A thorough inspection will show the most critical points in your fresh air supply system. Heinen & Hopman specializes in air handling unit refurbishment to offer clients an add-on to their standard maintenance program for climate installations.

Detailed working procedures have been developed to cope with all possible conditions. Per section, different measures are taken to bring equipment back to pristine condition and nominal performance.

Because every air handler is different in set-up, condition, location and requirements Heinen & Hopman applies tailor made solutions for every project. Thorough cleaning and disinfection procedures are applied to remove persistent residues that are present even after standard maintenance. Specially developed coatings are used to treat corroded parts resulting in smooth and seamless surfaces for the fresh air to pass through. Damaged insulation and other deteriorated or outdated parts are replaced to make sure the unit is set for years of service. Heinen & Hopman working methods and project planning minimize nuisance while applying its services to climate installations.

A total refurbishment is a cheaper, easier and faster option than replacement of complex air supply installations. A Heinen & Hopman refurbishment will revitalize your equipment. After this, a standard maintenance regimen is enough to keep the unit running in optimal condition With guaranteed fresh air supply for many years.

HEAT EXCHANGER PROTECTION Bacteria may grow anywhere, if the conditions are suitable, but cannot be trapped by filters or sieves. Bacteria may develop and grow in the presence of sulphur-, nitrogenor phosphorousbased compounds. In addition, the tubes in the condenser are among the hottest points in the refrigerant circuit, and therefore bacterial flora finds the most favourable conditions for growth in such tubes. Also in this case, the deposit of bacterial flora affects heat exchange and may be the cause of corrosion. Preventing the action of bacteria is not easy, as even “clean” water may over time give rise to the formation of bacterial flora. To prevent this phenomenon, continuous checks must be made on all the components in the water circuit.

Air-cooled heat exchangers suffer from corrosive attack in all kinds of environments. This corrosive attack results into high pressure failures, capacity loss, leakages and increased power consumption. Air-conditioning installations, power generation plants, oil & gas industry all depend on heat exchanging elements for a high efficiency and reduced down time.

Application Standard corrosive protective systems cannot be applied on heat exchangers. This is because of the complexity of the elements and the risk of capacity loss due to thick insulating coating layers.

Blygold has developed a revolutionary way to protect these vulnerable elements against failures and to ensure a long lasting efficiency.

Next to the special heat conducting coating the application technique is crucial for protecting all metal surfaces in a heat exchanger. The Heinen & Hopman spray technique cannot be compared to any other spray applied coating because the airflow technology creates a remarkable coating penetration without bridging.

Due to the Heinen & Hopman spray technology the coating can be applied either in-house or on-site. Heinen & Hopman protective system will at least double the heat exchangers lifetime but more often will triple it.
