Room comfort on cruise ships
To achieve the best possible cabin comfort, each cruise ship has a suitable heating and / or cooling system.

Terminal units

Cruise ships mainly use fan units. They supply the cabins with heating and / or cooling via a 2-, 3- or 4-pipe system. To control the room temperature, the most accurate results can be achieved at both full and partial load with pressure-independent balancing and control valves (PIBCV). They are simply set to the desired current at full load and act as an automatic flow limiter.

When a corresponding actuator is installed on the valve, the cabin temperature controller or the ship’s control system allows precise temperature control under part load conditions. There is no waste situation, which increases the energy efficiency of the heating or cooling source.

When the cabin has independent temperature controllers, these preferably not only control the actuator, but also include manual adjustment of the fan fan speed.

Underfloor heating

Provides a high level of comfort through heating rooms from floor to top. The heat is evenly distributed, and because it lies on the floor, it does not take up valuable space. It can be used to heat cabins, but it is mostly used to heat the bathroom floor where comfort requirements are highest.

Connected systems

Combined systems refer to the current state of the ship’s technical system data. This information can then be used for analysis and possible system improvements to provide convenience or operate more efficiently. Because these connected systems can be accessed via the Internet, they also save a considerable amount of time and budget.

We currently offer combined cruise ship systems in the following areas:

Smart concepts for the cabin

The innovative NovoCon® actuator is specially designed to integrate HVAC hydraulic balancing and control into BACnet or Modbus Ship Management Systems (SMS). It can replace SMS components and provide chained updated SMS system information. Once external data access to the SMS has been established, it enables the system to operate externally (from a ship or land).

When these digital actuators are installed on pressure independent balancing and control valves (PIBCV), all cabs can be controlled via the ship’s steering system. This also offers the benefits of remote access and integration with other SMS-connected systems, such as keyless entry, parasol management and dimming. By combining these technical systems through the ship’s steering system, “intelligent cabin control” can be created. From there, it’s an easy step to achieve highly effective fleet management and the ability to study the climate system of every ship from anywhere in the world.

Remote monitoring of hot water for households

Passengers and crew use very hot water during the trip. For this purpose, the vessel is equipped with a hot water system for domestic use. The hot water is then distributed to many faucet points. Due to their large sizes, cruise ships require a system with multiple risers circulating hot water.

Our temperature control valves ensure the right water balance and avoid long waiting times. Because they regulate water temperature, they also avoid too hot water, which causes lime, corrosion, and energy efficiency. Usually, these valves are set to a temperature that prevents the legionella from growing.

Temperature control valves can be equipped with electronic disinfection modules that allow the system to be flushed regularly to kill Legionella bacteria. Our temperature detection system monitors all temperatures and initiates an electronic disinfection cycle. It also stores temperature data for timber harvesting. The registration system can be easily connected to an SMS (Ship Management System) and give an alarm if it is registered for low or high temperatures. Depending on the SMS system, you can view and access water temperature information via the Internet.
