Main Applications
Thermoplastic tubes equipped with heating functions, for urea SCR systems.
These are environmentally friendly products used in SCR systems to detoxify nitrogen oxides (NOx) contained in diesel engine exhaust gas.
We can offer tubes for transporting coolant (LLC) and tubes for transporting urea water (AdBlue🄬), both of which are in actual use.
Features
Materials with excellent hydrolysis resistance are used for wetted parts.
The inner and outer layers are made of materials with high heat resistance, so they can be used in high temperature environments.
We can support various shapes by forming (bending) tubes.
This can contribute to improve the ease of routing such as in narrow spaces. (internal pass-through, LLC type)
With electric heater type urea SCR tubes, the defrosting capacity can be set individually for each item, to match the required performance.
Basic Product InformationRequest for documentation
Urea water tubes and LLC tubes are bound alongside each other, so the heat from LLC can be used to defrost the urea water. Since electricity is not used for heating, there is no power consumption.
■ Pipe routing can be adjusted according to the in-vehicle layout
■ Excellent water resistance and chemical resistance
This is a method for defrosting urea water using electricity. There are two types: an internal pass-through type in which the heater wire passes through the inside of the tube and heats the fluid directly, and an outer winding type in which the heater wire is wound around the tube outer diameter and the fluid is heated from the exterior of the tube. Since the tubes for urea water have their own stand-alone defrosting functions, piping can be routed in narrow spaces. The defrosting capacity can be set to suit your requirements.
■ Improved ease of pipe routing work
■ Optimization of defrosting capacity can reduce power consumption
■ Excellent water resistance and chemical resistance
Results of Use
■ Passenger vehicle manufacturers
■ Commercial vehicle manufacturers
■ Construction machinery manufacturers
We have results of use in a wide range of applications, including automotive applications, construction machinery, and industrial engines.
■ Commercial vehicle manufacturers
■ Construction machinery manufacturers
They can also be used as tubes for LLCs that can be adapted to various temperature ranges required for SCR applications.
Note that the above are only selected examples, and we are able to produce piping to meet customer needs.
We have many other results of use as well, so please feel free to inquire with us for more information.
Nitta’s Technology
We have results of use in the world's first SCR system for automobiles.
Tube composition, connector structure, defrosting capacity, etc. can be designed and developed internally to meet your requests.
We can support applications from tube extrusion molding, to assembly processing with connectors and other components.
Our lineup includes LLC type and electric heater type (internal pass-through, outer winding) defrosting methods
Properties for high water resistance and chemical resistance make them suitable for transferring urea water and LLCs. Excellent impact resistance and weather resistance for automotive and outdoor applications. High flexibility allows greater freedom in pipe routing.
Two types of defrosting methods can be proposed according to customer requirements.
■ LLC type SCR tubes that do not consume power
■ Electric heater type SCR tubes whose defrosting capacity can be set according to requirements
We can manufacture tubes with high dimensional accuracy through closely controlled processes.
Tubes can be formed (bent) and processed into desired tube shapes. Since they can be useful to eliminate interference during assembly, they can be considered for routing in narrow spaces.
We can offer processing such as press-fitting connectors (joints) to both ends of tubes, attaching protectors to tubes, and installing clips.
We can propose tube specifications according to the defrosting capacity requested by customers. (Electric heater type)
