How it works?

When the engine preheater 220V withThe pump is connected to the system, electricity is supplied to it. As a result of this process, a tubular electric heater is turned on. Its main task is to raise the temperature of the antifreeze. The heated liquid then enters the cooling system. This happens with the help of a pump, as well as an impeller, which is installed in the device.

Thus, a constantcirculation in the system. The engine warms up slowly and evenly. In order to maintain the optimum temperature in the system, there is a thermostat. If necessary, it is able to open the contacts, and no voltage will be applied to the tubular electric heater.

Correct installation of the device

How to Install a Preheating Heaterengine? Answering this question, it should be understood that much depends on its modification, but there are general provisions on this matter. First of all, it is important to remember that the device must be connected to a single-phase network. In this case, the contact must be grounded. This is done by means of a circuit breaker, which is protected against current.

Also some advise on installationequipment use a shutdown system. This device will significantly protect the installation process of the model, and the risk of electric shock will be minimal. Any shorting in the wiring can lead to a fire. Considering this, during work, it is not necessary to touch non-insulated sections of equipment. When starting the pre-heater, it is important to inspect the cooling system. The device must be connected from the side of the cylinders. In this place there must be a branch pipe, the diameter of which is 20 mm.

Then place the device in a horizontalposition. Ultimately, it must be below the level of the radiator. This is done in order to prevent the device from being airborne. The fixing point can be changed if necessary, by using an additional hose. As a rule, it is added to the model. After connecting the device, it must be fixed to the body. In some cases, this is quite problematic. However, it is considered a gross mistake to fix the pre-heater to the silencer manifold. In most cases this is unsafe and can lead to a fire in the car.

What determines the power of the preheater?

First of all, the capacity of the pre-startThe heater is connected to the maximum frequency of the device. Usually this parameter is within 50 Hz, however, its deviations are possible. Additionally, the piston diameter is taken into account. Its size ultimately affects the flow velocity of the flow.

The higher the operating power of the device, the fasterthe temperature is dialed. Usually in the engine, the antifreeze is capable of heating up to 60 degrees. The average heating time is 3 minutes. In this case, much also depends on the location of the pre-heater. As stated earlier, it must be securely fixed and not blown.

Important Device Settings

Important parameters of pre-heatershould be attributed power. This is measured in kW. If we take a model with a power of 1.5 kW, the heating time of the antifreeze will be approximately 3.5 minutes. If the above figure is 2 kW, then the required temperature can be reached in 3.2 minutes.

In this case, the type of current is taken into account, and also the limitingfrequency, which is measured in Hz. It depends on the temperature of the thermostat. The indicator of the circulation flow is measured in liters per second. It is largely related to the diameter of the inlet, as well as the outlet. On average, the nozzles are made with a size of 12 mm. In this case, the dimensions of the device itself can be very different. On average, the preheater length is 150 mm, width - 90 and height - 90 mm.

Device protection is classified bydegrees. The most common models are marked "IP34". This inscription says that the device is safe for human health, and cases of short circuits are virtually eliminated. In addition, the customer from the parameters must check the plugs. If we talk about Russian manufacturers, they equip their models according to European standards. On average, the mass of the device fluctuates around 1 kg. A good pre-start heater of the 220V engine with a pump for the buyer in 4 thousand rubles will work.
