2.1.3.Opening the Refrigerating System with

Refrigerant R134a for Repairs

As R134a has other properties than the R12 used till now, it is important to note the following before opening the hermetic refrigerating system:

1.Service Tools

Do not use service tools that have been used for chlorine- containing refrigerants because microscopic chlorine resi- dues may cause a chemical reaction in the refrigerating system.

2.Evacuation

As the oil used for R134a has the property that it absorbs more moisture than the oil used for R12, it is necessary to evacuate 5- 10 minutes after the system has been evacuated to the required vacuum.

3.Recovery

Be careful, at the recovery of R134a, that no air goes into the recovery tank as there may be a danger of explosion at high pressure, and a safety valve should therefore

be mounted on the tank for used refrigerant.

4.Filter Drier

A filter drier with desiccant XH9 is to be used. This service filter has part No. 0-6538053 and price code V3. The filter drier for emptying unit has part No. 04.99.54.066.

5.Oil

The oil of the filling station and emptying unit should be changed when needed.

The oil for emptying unit has part No. 04.99.54.070. The oil for filling station has part No. 04.99.54.065. These oils, which have to be used for R134a, are polyol ester oil.

Remember to put back the lid on the oil can after use, as the oil will otherwise absorb moisture from the air.

6.Marking with R134a

The amount of filling is indicated on the rating plate of the unit. As to the compressors for R134a the refrigerant type is indicated on the rating plate placed on the front of

the compressor.

375 specifications

Equator 375 is a state-of-the-art maritime vessel that has garnered significant attention in the shipping and logistics industry due to its innovative design and advanced technologies. This vessel is specifically engineered to meet the growing demands of global trade while minimizing environmental impact.

One of the standout features of the Equator 375 is its impressive cargo capacity. With a deadweight tonnage of 37,500 tons, this vessel can accommodate a wide variety of cargo types, including bulk goods, containers, and project cargo. Its versatile design makes it suitable for multiple shipping routes, enhancing operational efficiency and reducing transit times.

Equator 375 is equipped with cutting-edge propulsion technology. It utilizes a dual-fuel engine that can run on both heavy fuel oil and liquefied natural gas (LNG). This flexibility allows the vessel to operate more sustainably, significantly reducing greenhouse gas emissions and complying with international regulations. By adopting LNG as a fuel source, the Equator 375 contributes to a cleaner maritime environment, helping to meet stringent emission targets.

In terms of navigation, the vessel features an advanced integrated bridge system that enhances operational safety and efficiency. The system includes state-of-the-art radar, automatic identification systems (AIS), and electronic chart display systems (ECDIS). These technologies ensure that crew members have access to real-time data, improving situational awareness and decision-making during voyages.

Equator 375 also prioritizes crew comfort and safety. The living quarters are designed ergonomically, with modern amenities to provide a comfortable environment for the crew during long voyages. Safety equipment is installed throughout the vessel, including fire suppression systems and life-saving appliances, ensuring that crew members are protected in case of emergencies.

Moreover, the vessel is designed with an eco-friendly hull shape, reducing water resistance and optimizing fuel efficiency. This hydrodynamic design contributes to lower operating costs, making Equator 375 not only a technologically advanced vessel but also a cost-effective option for shipping companies.

In summary, the Equator 375 is a remarkable addition to the maritime fleet, featuring impressive cargo capacity, advanced propulsion technology, and a focus on crew comfort and safety. Its eco-friendly design and innovative navigation systems position it as a leader in sustainable maritime transportation, paving the way for the future of shipping.
