Thermal Oil Heaters
Hot oil heating systems are applied in facilities that require high temperature liquid flow during production. The most important feature of this system is that it can reach the highest temperature at a lower pressure.
Vimpo Thermal Oil Heaters are used to obtain the high temperature fluid requirement at low pressure values. Hot oil systems enable to reach high temperatures, which heat transfer fluids such as water-steam cannot reach, at atmospheric pressure.
Thermal systems are used in countless production methods, and various industries require thermal oil to carry process heat. The oil in the Vimpo Thermal Oil Heater is heated with flue gas and works as a single pass system.
Vimpo Thermal Oil Heater is suitable for burning diesel and natural gas. They are composed of intertwined spiral-shaped pipe bundles. The harmful effects that may occur due to heat are eliminated by these spirals. Thermal oils are used for heat transfer in hot oil boilers. It can work without pressure at high temperatures.
All the oil in the system circulates in the spiral pipes, after it is heated, it leaves the boiler and is conveyed to the necessary places. There is a fully controlled flow. The thermal oil, which is used as a heat carrier in the system, does not leave residue in the installation and does not cause scale.
Equipped with unrivaled technology, Vimpo VTH Thermal Oil Heater offers high efficiency to the user. Vimpo Thermal Heating Plant with a capacity of 200-2.000.000 kcal/hour is designed as container type for easy transportation.

How To Use Vimpo VTH Thermal Oil Heater
Vimpo VTH Thermal Oil Heaters are used in various fields such as textile, paper, chemistry, food, paint, leather, construction, crane manufacturers, petroleum. It is used in processes that are required in industrial facilities and require high temperatures.
Put the liquid in an open container and start heating it to determine the flash point of the liquid. Meanwhile, an electric arc and gas flame form on the heated pot. Due to the increased temperature, the liquid begins to evaporate.
When there is enough steam, the steam starts to ignite with an open flame and flashes. The liquid temperature at that moment is defined as the flash point of the liquid. The liquid must then continue to be heated to produce much more steam.
In this way, instantaneous flashes turn into permanent flames over time and the fluid temperature is known as the burning point. Thermal Oil Heating Systems flow and work in insulated lines. Closed cell type insulation or non-isolated insulation is recommended for possible leak sites.
After the plumbing connections are made and the system is filled with oil, the Circulation Pump is started and the correct rotation is checked according to the direction sign on the pump.
If the differential pressure lamp lights up after the circulation pump starts, the Burner On-Off latch button is moved to the right and the Burner On lamp lights up and the burner start command goes out. Working Thermostat has 2 digital indicators. In the section that says PV, it shows the oil temperature coming out of the instantaneous heater. The part that says SP indicates the temperature at which the burner will stop.
It can be increased or decreased with the up and down arrow keys. The first of the 2 digital indicators on the Safety Thermostat, the part that says PV, shows the instant oil temperature. The part that says SP is the temperature value at which the burner will stop for safety. It is changed with the up and down arrow keys. The Ø80 valve placed in front of the deaerator is closed and then the barrel is filled. The oil capacity level is monitored from the expansion tank level indicator.
The oil level should be 1/3 of the volume of the expansion tank. Then the system should be rested for 1 hour. The circulation pump should be started before the boiler is started. The pump is started by reading the manometer pressure value from the pump outlet.
The burner unit is connected with a circulation pump unit, expansion tank level, flow sensor and safety thermostats. It should be kept in mind that the burner cannot operate without the pump running, the burner cannot operate due to the lack of oil level in the expansion tank, and the burner cannot operate when the system is at a high or sufficient level temperature.
In fuel oil system applications, all of the pre-heaters must be turned on at least half an hour before starting the burner unit. (line, pot, burner pre-heaters) The circulation pump is started. The set value of the output thermostats is adjusted. Then the burner unit is started. It should be ensured that the system temperature reaches 100 C°. The burner is stopped. The burner should be paused every 20°C and the system should be checked each time until the set value is reached.
When the set value is reached, it should be observed whether the burner stops or not, and when the set value decreases, it should be checked that the burner works again. The burner must be turned off to stop the heater. The refractory and steel material will continue to heat the oil due to the absorbed heat. The pump should be turned off when the system is colder.
Thermal Oil Heaters Maintenance
While around the pipelines of the Thermal Oil Heater, the valves and threaded joints should be checked. Odor can be a clue and a harbinger of leakage. The system vent pipe placed above the expansion tank should be monitored to detect the arrival of steam or soot, as this is a sign of water presence or the onset of oil separation
If hot oil escapes into the expansion tank while the system is running, it narrows the diameter of the boiler ventilation pipe and prevents the hot oil from reaching the expansion tank. Hot oil can ignite very easily after contact with air. Pay attention to vibration or odor while circulating in the plumbing system, its source must be found.
Due to possible fires, sufficient fire extinguishing equipment should be kept in the right and easy to find places.
