Ultrasonic Antifouling Devices

Biofilm consists of micro-organisms in which cells are sticking to each other. These micro-organisms are able to multiply under favourable conditions and as a result will form biofilm. This biofilm is the attachment and food base for every further fouling and growth as algae, barnacles or shells.

Fouling as the result of biofilm causes a lot of issues like corrosion, formation of micro-organisms and deterioration of heat transfer as well as cross-section reduction and blockages. All these issues lead to the fact that chemicals or other environmental unfriendly procedures are required. In addition to the environmental effect all these issues are causing higher costs of maintenance and will lead to higher operational costs as well as to increased total costs of ownership in the shipping industry.

Marine Biofilm Removal

The removal of biofilm is really difficult since it has the ability to protects itself. In addition, if remaining parts of biofilm are not completely removed, subsequently this will lead to an accelerated regrowth of micro-organisms. Therefore biological fouling prevention is a major target in the pre-treatment process. It will directly save costs and will contribute to an environmental friendly and sustainable solution.

Clever Marine Services are experienced in the adjacent preventative and remedial marine anti-fouling processes.

HASYTEC DBP Marine Antifouling Devices

HASYTEC DBP Product Highlights

HASYTEC DBP is the result of 22 years electro technical marine experience and prevents biofilm which is the initial basis of all fouling and marine growth. It is developed to combat fouling and growth on every liquid carrying surface.

HASYTEC DBP is currently the only system on the market which enables 8 transducers emitting ultrasound at the same time which increases the effect and the covered areas enormously.

Highly effective and efficient against biofilm, fouling, marine growth on:

  • Hulls
  • Box Coolers
  • LT-coolers
  • Strainers
  • Fresh Water Generators
  • Propellers
  • Bowthrusters

Highly effective and efficient against biofilm and clogging on liquid carrying surfaces like:

  • Pipes
  • Plate Heat Exchangers
  • Tanks
  • Process Water Lines

HASYTEC DBP is designed and manufactured in Germany.

HASYTEC DBP Technical Highlights

  • Modular control unit controls up to 8 transducers which are emitting ultrasound at the same time
  • Casted alloy casing, protected in IP 66 standard, powder coated (DNV GL approved)
  • Protected cables (DNV GL approved)
  • Cable routing in stainless steel (DNV GL approved)
  • Cable length up to 25m

HASYTEC DBP Advantages

  • Reduces the costs of fouling and bacteria prevention
  • Reduces operational costs
  • Reduces the Total Cost Of Ownership
  • Environmental friendly and sustainable
  • Maintenance free
  • 5 years warranty

HASYTEC DBP Working Principles

The uniqueness of HASYTEC Dynamic Biofilm Protection is the combination between the “low power” consuming transducers and the intelligent software, which results in the transducers to be directed highly focussed and controlled. HASYTEC DBP runs a very precisely tuned program of several frequencies and power consumptions.

The transducers need to be glued with special industrial glue onto the requested applications. The metal transports the ultrasonic signals into the liquid (mostly water) and as a consequence it will diffuse completely through the medium (see pictures). These diffused ultrasonic waves will prevent the biofilm and will even remove it in early stages. Consequently HASYTEC DBP prevents fouling, marine growth, bacteria, clogging and blockage.

Due to the fact that the emitted ultrasound is running on several different frequencies which only avoid biofilm and destroy unicellular organisms, it doesn’t harm the environment as fishes, dolphins, whales or human beings.

The HASYTEC DBP system needs a constant power supply which has to be provided 24/7. It consumes max 20 Watt per transducer and requires no routine maintenance.

Due to the fact that HASYTEC DBP is a preventive system it’s necessary to start with a clean surface.

Installation of HASYTEC DBP is very easy. There is no need for the vessel to go to dry dock. The installation can be realised at any given time. Only hull protection installations require dry dock conditions to reach the ballast water tanks, if applicable.
