Application and working principle
Designed for installation on standard fuel intakes of vehicles with supply voltage 12V and 24V.
Installed inside the fuel tank on the standard fuel intake.
The attachments are designed to take up to 420 l / h of fuel at temperatures from -40 ° C to + 45 ° C.
Fuel heating time during the pre-start period is no more than 5-10 minutes.
In low temperature conditions, the fuel can be continuously heated while the engine is running. The electric heater implements the functions of dynamic heating control: it automatically increases the heating power to the maximum value in the presence of fuel flow through the nozzle, reduces the heating power to the minimum in the pre-start mode, prevents the heater and fuel from overheating above 130 ° C.
Efficiency
You can evaluate the efficiency of the heater by watching a video recorded during tests on the intensity of heating of the fine filter.
The initial filter temperature is -22 ° C. Demonstration speed increased by 10 times. The real warm-up time is shown in the upper right corner.
Installation
Installed at the end of the fuel pick-up tube with set screws.
The nozzle is connected to the vehicle's electrical system according to the connection diagram (see. passport).
Control
The heater is switched on and off using a switch located in the cab.
A lit LED in the cab indicates that the heater is on.
Quality and guarantees
They remain operational when the supply voltage changes within 90-125%.
The service life of the heater is at least 5 years, the mean time between failures is at least 3000 hours.
Choosing a model
To select a model you need to know the voltage of the on-board network (12V or 24V) And also the maximum consumption of diesel fuel for the NTP-301, 302 models is 680 l / h. The presented models also differ in heating power.
Model list:
| Model | Voltage | Fuel consumption | Power |
|---|---|---|---|
| NTP-301 | 12B | 680 l / h | 200W |
| NTP-302 | 24B | 680 l / h | 350W |
For best results, it is recommended to install it together with a fine filter heater (band or disc) and a flow heater.
