   General Container

   
   Structural design description:
   The internal space is divided into two spaces: engine room and control room, and inspection channels on both sides of the equipment inside the engine room.
   
   Functional description:
   1)The container is equipped with a distribution box to provide power to all low-voltage loads in the engine room, such as horizontal radiator fans, control screens, lighting, exhaust (supply) fans (for horizontal distribution), chargers, electric heating (optional), oil pumps, electric heating (optional), and outdoor searchlights. It can also be responsible for controlling related equipment (according to project configuration requirements);
   2)Two track suspension beams and a hoist are installed on the top of the engine room, with a lifting capacity of 0.5 tons per beam;
   3)Inlet of engine air filter and the engine room are equipped with electric heating devices to avoid freezing and blockage (optional);
   4)The floor of the machine room is equipped with an axial drive mechanism for the generator, which enables the generator to detach from the coupling by 200mm. (Optional)
   5)If the indoor heating temperature in the machine room is not lower than 5 C deg., an insulation layer needs to be installed under the chassis of the machine room, and electric heating heaters (optional) are used inside the machine room;
   6)One explosion-proof acoustic and visual alarm lamp is installed outside each machine room. The lighting inside the machine room is an explosion-proof LED lamp with emergency function. Other equipment and boxes do not need to be explosion-proof (optional).
   7)Ladder: Install a simple ladder at a suitable position on the box;
   8)Configure the fire protection system in the machine room: Install dry powder fire extinguishers as fire extinguishing devices (standard), and other flame detectors, methane leak detectors, smoke detectors, etc. as optional options;
   9)Note: The specific configuration shall be subject to the actual situation of the project.
   
   

   OPTIONS

   
   CHP system (Exhaust Heat Collector) CHP/ Cogeneration/ CCHP/ Trigeneration
   
   1. The unique spiral winding structure increases the turbulence effect, and the heat exchange capacity per unit area is 3-7 times that of the traditional heat exchanger.
   2. High heat transfer coefficient, high heat exchanger heat transfer efficiency, good heat transfer effect, high heat transfer coefficient up to 14000W/m·k, energy saving effect is remarkable.
   3. Small size. With only one-tenth of the traditional tube and shell heat exchangers, it takes up less space and reduces infrastructure and installation and maintenance costs.
   4. Using a small clearance design to increase the flow rate, the heat exchanger is not easy to foul, and the use and maintenance costs
   are low.
   5. Advanced design concept, the length of the heat exchange tube is 3-4 times the height of the cylinder, the material stays longer and the
   heat transfer is more fully.
   6. Spiral-wound elastic tube bundle design can effectively eliminate pipe vibration and stress due to thermal expansion and contraction deformation.
   7. Unique 90 degree connection, heat exchangers all participate in heat exchange,
   no dead ends and stagnant areas, reduce fluid resistance.
   8. Counter-current heat transfer, asymmetric flow design, in the vapor-liquid heat transfer field has other advantages that can not be compared with heat exchangers.
