Planar: technical device, principle of operation, fault codes for heaters 2d, 4dm and 8dm

The Planar air heating device, produced in Samara, is widely popular. If there is not enough heat in the car, it is an indispensable assistant, even in the most severe winter weather. In the cabin of a small passenger car model or a spacious van, the driver and passengers become as comfortable as possible in a short period of time.

The operation of the device is based on a simple principle - drawing surrounding air masses into the heating chamber. When fuel burns, thermal energy is released. It is sent to heat the air, which then enters the cabin.

Advantages and disadvantages

The device can work autonomously when the car engine is turned off

The Planar heater helps out many drivers. Truckers, bus drivers, and travelers are forced to spend a lot of time in the car cabin. In the cold season, heating the interior due to engine operation is insufficient. Planar solves this problem.

Advantages of the device:

In an hour, the heater, depending on its power, heats from 34 to 120 cubic meters. m. air.
The planar is economical - with such high efficiency it consumes no more than 29–42 W. The same volume of heated air requires from 0.24 to 0.37 liters of diesel fuel per hour.
Planar is effective at very low temperatures outside – below -20 C.
The installation works without time restrictions. Automatically turns off when the specified temperature is reached and turns on when it drops. You can turn off the device manually.
The device is safe. If it rolls over, has a weak flame, the flame goes out, or there is an interruption in the air or fuel supply, the Planar turns off.
Noise level is low.
If you connect air exhaust pipes, warm air can be directed not only into the cabin, but also into the bus interior or into the cargo compartment if the cargo being transported requires a certain temperature regime.
The device operates autonomously from the car engine. This is a convenient option for spending the night in the car, as the Planar can heat the cabin all night long.

There are no disadvantages. Autonomous car heater Planar fully corresponds to its purpose.

The inlet hole must be placed so that the Planar does not suck in exhaust gases during operation.

Specifications

Let's consider the popular model 4DM 12 24. This is also a Planar autonomous vehicle. Its price is 19,400 rubles. The device is a diesel autonomous heater. The device has the following technical characteristics.

Thus, the level of heat production is 3 kW in active mode, and 1 kW in low mode. Fuel consumption in active mode is 0.36 l/h. In low mode, the device consumes up to 0.12 l/h. Power consumption – up to 30 W. Injected air – 120 m3/h. The supply voltage is 12 and 24 V. All these characteristics were measured at rated supply voltages and a temperature of 20 degrees. There may be a slight measurement error.

Automatic electronic adjustment

"Planar" has an electronic control unit. It automatically regulates the temperature. The setting is carried out according to values preset by the driver. Range - from 15 to 30 degrees. When the temperature inside the car reaches the set value, the device will continue to operate in reduced power consumption mode - the heat transfer will be less.

If the difference between the set temperature and the actual one is large, then the electronics activates the ventilation mode. This allows the driver's workplace to be cooled. When the air temperature begins to drop, the equipment will go into active mode. As an option, the device can be equipped with a remote temperature sensor.

Monitoring and control system

Using the control unit you can regulate the amount of heat

The Planar heater operates in several modes. Operational safety, adjustment and diagnostics of systems are ensured by sensors and a control unit.

Control block

The module is housed in a housing and connected to executive units with switching loops. Its functions are as follows:

turning the device on and off;
control and management of the fuel combustion process;
initial diagnostics in case of breakdowns during startup;
automatic ventilation after Planar stops;
emergency shutdown in case of breakdown of any component, flame extinction, power surges, heat exchanger overheating and other situations.

The control unit works together with the remote control.

Operating modes

The device simultaneously performs the function of interior ventilation

The autonomous air engine heater operates in 3 modes. However, use often depends on the model’s configuration:

In terms of power, it heats up the interior as quickly as possible. The heater, set to a certain power level - from 1 to 8, operates continuously until the device is turned off manually.
By temperature – the heater warms the air to the set temperature. The heater then turns off and automatically turns on again as soon as the air has cooled to the specified minimum. In automatic mode, the device operates until manual shutdown.
Ventilation – provides air exchange. Combined with temperature or power control. The temperature is maintained with high accuracy and does not fluctuate within the specified range.

Control panels

The remote control is installed on the dashboard or hung on a container in any place convenient for the driver. The device is connected to the device via a cable. The remote control is convenient because it regulates the operation of the Planar and serves as a diagnostic tool.

The heaters are equipped with different types of remote control:

PU-10M – allows the Planar to operate in power and temperature modes; ventilation is not provided. Equipped with LED indicator.
PU-5 – allows Planar to operate in all modes. The potentiometer flywheel is equipped with a conditional graduation, so that the temperature can be set more accurately. An indicator indicates operation and malfunctions.
PU-22 - functional buttons allow you to select a mode, a temperature sensor, the readings of which will be considered control, change the power and temperature indicators. Information about the Planar’s operation and breakdowns is reflected on the LED screen.

By the number, color and behavior of LEDs, you can determine the cause of the problem and quickly eliminate it.

Operating instructions for the Planar heater

You can install and run Planar yourself, but if you have no experience working with heating systems, you need to invite a specialist.

When turned on, Planar conducts testing, and if all elements are in working order, it begins ignition. First, the chamber is purged, then diesel fuel and air are supplied. The burner operates until the sensor registers the set value. After this, the device turns off if it is not operating in power mode.

After manual shutdown, the Planar is automatically ventilated.

Safety precautions

When refueling the Planar, you must turn it off.
The cabin or car interior is a very small room. Safety precautions must be strictly observed:

there should be a fire extinguisher in the car, and at least a bucket of sand in the shed or garage;
It is prohibited to lay the fuel wire inside the passenger compartment or cabin;
during refueling the device is turned off;
during repair and welding work, the heater is disconnected from the battery;
It is prohibited to disconnect the device from the power supply until the purge is completed;
after stopping the device, turn it on again no earlier than after 5–10 seconds.

If safety regulations are not followed, the manufacturer has the right to refuse warranty service.

General signs of malfunction of Pramotronic liquid heaters

Symptoms of a problem	Possible reasons
The control lamp does not light up, the heater does not work.	There is no supply voltage, the fuse or control lamp has burned out, there is no voltage supply to the terminals of the control unit.
The heater often turns off.	The coolant flow is too low because: there is air or other gases in the heater, vehicle heat exchangers or areas of the fluid system; insufficient performance of the circulation pump (air bubbles in the pump); the direction of rotation of the pump impeller has been changed; the resistance in the liquid system is too high; the fluid system is dirty; The circulation pump is faulty. The liquid in the circuit gives off too little heat because: there are air bubbles in the connected heat exchanger or other parts of the system; internal or external heat-releasing surfaces are dirty; there is insufficient air flow to the heat-transferring surfaces or outflow from them; insufficient performance of the car fan; too much antifreeze content; heat sink power is low.
There is no fuel supply to the heater.	The fuel tank is empty. Pipelines are leaking, bent, or clogged. There are large deposits of paraffin in the fuel filter, and the water is frozen. The vent in the tank is closed. The fuel lines on the heater are reversed. The fuel filter is dirty.

Design and operating principle

The heater has a voltage regulator and a timer. Constant work in offline mode is possible. Ignition is started electronically only if all requirements are met and the components are in full working order, so there is no reason to worry about the safety of the design.

The main components of Planar:

power unit;
heating element;
pump for pumping fuel.

The operating principle of the autonomous unit is to supply air from outside to the heating compartment. This air is heated by the energy generated by the combustion of fuel. The warm air is then released into the interior of the car, van or bus.

The planar consists of 3 main elements

Advantages of using air heaters:

low cost;
low fuel consumption;
work is set according to temperature or power;
when the engine is turned off during long periods of inactivity of the machine, very little electricity is consumed;
does not make much noise;
due to the brushless motor, the service life is increased;
Design diagnostics are carried out automatically.
