Cold and freezing room
Lighting in cold- and freezing rooms should provide a safe working environment by achieving a certain level of light intensity even at low temperatures. In addition a low power consumption is required to reduce the additional cooling due to the heating from lighting to a minimum.
Different areas on the ship require special demands for lighting
Cold/freezing rooms on Navy or Marine vessels are classified as areas where very low temperatures are present. This rooms are used for storage of food and have to be easy to clean. Luminaries should be designed according to USPH (United States Public Health) As well as being easy to install, the fixtures should also be maintenance-free and should provide sufficient light intensity at low temperature.
Important factors when selecting lighting solutions for cold/freezing rooms:
- Easy to clean.
- Low minimum ambient temperature class.
- No maintenance and reduced power consumption (less power consumption means less cooling is required).
Easy to clean
The correct design of the luminaire is important in order to ensure an easy cleaning to avoid impurities. The correct design of the luminaire is important in order to ensure an easy cleaning to avoid impurities. When using brushes, pipes and sometimes high-pressure cleaners, the luminaires must have a high IP protection rating to withstand these pressures. The Glamox Group recommends the use of IP66/67 lighting for these areas.
Using the correct combination of materials in the luminaire is important in order to ensure robustness and a long operating life. Materials and design have to be specially selected to withstand possible mechanical damages by handling with frozen goods.
Low minimum ambient temperature class
Temperatures in cold storage, refrigeration and freezing rooms on Navy or Marine vessels can drop to as low as -40°C. It is therefore critical that the lighting solutions installed in these areas are carefully selected to operate reliably at these temperatures. The lighting illumination should have an average level of 200 lux.
No maintenance and reduced power consumption
An important requirement onboard a Navy or Marine vessel is to install luminaires that are virtually maintenance-free. This reduces or eliminates the labour costs primarily associated with the maintenance, servicing and replacement of luminaires. The luminaires in freezing rooms should consume as little energy as possible in order to reduce the additional cooling due to the heating by luminaries. The efficiency and life span of LED lighting continues to improve. LED luminaires are virtually maintenance-free, which means that vessels with LED lighting will have lower operating costs compared to vessels with conventional luminaires. The initial investment of the LED installation may be higher than a traditional lighting installation, but the LED’s reduced energy consumption and lower maintenance costs means that this price difference will be quickly recouped and payback on the investment is recovered quickly.
We always recommend the use of Navy or Marine-approved lighting products in cold/freezing rooms.
