Galley exhaust air purification on ships – efficient, safe, low-maintenance

Specialized detection systems for yachts and cruise ships

Galleys have very limited space and at the same time place the highest technical demands on ventilation systems, fire protection and hygiene.

With 20 years of experience on cruise ships and luxury yachts, oxytec manufactures individualized exhaust air systems for the removal of grease fumes, steam and odours. With careful planning, prefabrication and fast installation, we adapt to the limited time windows in the shipyards.

From our range for galley exhaust air

Planning

Calculation and planning of the entire galley exhaust air system

Minimization of the required supply air and exhaust air volumes to save energy

Project management until final acceptance

Exhaust air hoods

Hoods and ducting systems from a single cast, prefabricated and continuously welded

Low energy consumption thanks to Demand Galley Ventilation

Automatic washing systems for the exhaust air ducts

Compliance with the strict USPH requirements

Damper covers

Removal of steam and condensate via specially designed hoods for hobs and dishwashers

Automated drainage of condensate

heated systems are also available.

Supply air systems

Air supply for stabilization of the exhaust air, generation of negative pressure in the kitchen to prevent odours and for healthy breathing air in the kitchen

Exhaust air purification

Elimination of grease in the exhaust air avoids fire loads in the exhaust air ducts and unwanted odors.

Automated scrubbing systems make exhaust air purification easy to maintain.

Adaptation to the ship informatics

Save energy – Demand Galley Ventilation

The treatment and air conditioning of the room air requires the second-highest energy consumption on board. The galleys consume a large proportion of this energy.

Instead of continuously providing a high volume of air for the galleys so that there is always enough air, we control the air volume as required using heat sensors. This saves up to 70% of the energy used – and significantly reduces the noise level.

Automated flap systems dimension supply air and exhaust air according to demand. The total volume of air required can therefore be significantly reduced.

As the temperature sensors are fitted directly in the hoods, installation is also possible after the kitchen has been installed. The electrical installation is much simpler than with sensors in the cooking appliances.

Energy consumption drastically reduced –
without and with demand galley ventilation

Avoid fires – thanks to integrated UV-C exhaust air purification

Grease deposits in exhaust air ducts are a high fire risk. Our hoods eliminate grease directly at the source:

  • Highly effective mechanical grease separators

  • Integrated UV/ozone technology for the decomposition of residual particles

  • Compact, space-saving design – ideal for use on board

This technology not only protects against fires, but also reduces unpleasant odors and increases the safety of the entire ventilation system.

Control supply air for occupational safety and comfort – and save energy too.

Thanks to intelligent air routing with the Injection Return Hoods:

  • Supply air is used as an invisible air tent

  • Reduces the required extract air volume flow by up to 65 %

  • Smaller duct cross-sections and significantly lower energy and air conditioning costs

Less maintenance – more uptime

Our CKA marine system is specially designed for continuous operation at sea:

  • Almost complete removal of grease – the exhaust air ducts remain clean

  • Automatic hood cleaning through integrated washing unit

  • Significantly reduced cleaning effort and maintenance interval

Result: Significantly longer maintenance cycles, lower operating costs, higher reliability.
