Diesel indirect-fired heater 50 kW CIMEX D50i

CIMEX D50i is an indirect-fired diesel heater designed for heating large spaces such as sports halls, manufacturing facilities, animal farms, poultry farms, warehouses, tents, and more. Unlike direct-fired heaters, indirect-fired heaters have a flue to exhaust the burnt gases outside the space where the heater is located. This allows for heating without the presence of burnt gases and odors in the room. Another option for using the diesel heater to heat spaces without consuming oxygen and producing burnt gases is to place the heater outside the space to be heated and deliver heated air to the room through a flexible air duct. Thanks to this, the indirect-fired diesel heater can be used for emergency and primary heating of spaces with poor ventilation where people are present for an extended period of time.

With a power output of 50 kW, the indirect-fired diesel heater is suitable for primary and supplemental heating of large spaces up to 2048 m³.

In the construction industry, this type of heaters serves two main purposes – maintaining temperature and/or drying. Depending on the purpose, if the diesel heater is used to maintain temperature, it can be placed inside or outside the building. When it comes to drying, maximum efficiency is achieved when the diesel heater is positioned inside the space.

In livestock farming, the diesel heater with indirect combustion is an excellent option for heating parts of animal farms, poultry farms, and more. For this purpose, the optimal placement for the heater is outside the building where the animals are raised (if the ventilation is poor, there's high dust levels, or fire hazards), and by using an additional temperature sensor, the desired temperature inside the building can be maintained.

When heating warehouses for goods and agricultural products, the heater can be placed inside the building, and the built-in thermostat can be used to maintain the desired temperature without the need for an additional external thermostat.

Maximum efficiency and speed in heating indoor spaces are achieved when the heater is placed inside the room, as it allows for the circulation of already heated air (preheating).

D50i Diesel Heater with Indirect Combustion - Schematic view of how the diesel heater with indirect combustion works:

The main components of a diesel heater with indirect combustion are:

1. Fuel chamber
2. Exhaust stack
3. Burner
4. Fuel nozzle
5. Electromagnetic valve
6. Fuel line
7. Fan
8. Electric motor
9. High-pressure fuel pump
10. Cable clamp
11. Fuel tank
12. Control panel

When the diesel heater with indirect combustion is turned on from the control panel (12), the electric motor (8) is activated, which in turn drives the fuel pump (9) and the fan (7) that supplies the necessary amount of air for combustion and circulates the outer part of the fuel chamber. The gear fuel pump for high pressure, driven by the electric motor, draws fuel from the tank (11) and, through the fuel line (6), passes the high-pressure fuel to the nozzle (4) of the burner through the electromagnetic valve (5). The nozzle sprays the atomized fuel into the fuel chamber (1), where it ignites through ignition electrodes.

As a result of the combustion process, the outer part of the fuel chamber heats up, and due to the air circulation from the fan, the air is also heated.

The outer part of the diesel heater is made of sturdy sheet metal and protects its components from environmental influences, directs the airflow of the fan, and serves as a temperature shield, separating the fuel chamber from the surrounding environment. This way, the heater's body does not overheat even during prolonged operation.

The combustion process is controlled by precise electronics, which monitors the combustion process through a photocell, and in case of anomalies during combustion, the machine is turned off.

To reduce fuel consumption, the diesel heater is equipped with a thermostat as standard, which, when the set temperature is reached, turns off the heater.

The fuel delivery is entrusted to a robust and reliable high-pressure gear pump from one of the leading companies in the field - Danfoss (Denmark).

Once again, the fuel nozzle is provided by Danfoss (Denmark) and features a built-in ceramic filter.

To reduce fuel consumption, the diesel heater comes standard with a built-in thermostat. When the set temperature is reached, the heater is turned off.

The combustion process is monitored by precise electronics using a photocell, and in case of anomalies, the machine is shut down.

The internal thermostat is built into the machine and is used when the machine is located inside the room that is being heated.

The heater has the option for working with a second thermostat (room thermostat) (not included in the package) that is used for remote temperature control and is placed inside the room being heated when the diesel heater is mounted outside or in an open area.

IMPORTANT: When the room thermostat is turned on, the built-in thermostat is bypassed (i.e., it does not function).

The desired temperature is set using the thermostat located on the control panel, and two LED displays show the set (desired) temperature and the currently measured temperature.

The fuel chamber is equipped with thermal protection against overheating.

To ensure maximum runtime, the diesel heater comes with a 56-liter fuel tank. With this tank capacity, you can achieve up to 17 hours of CONTINUOUS operation on a single fill.

For convenience during transport and mobility, the diesel heater comes standard with large transport wheels.
