ead below for our top three benefits to purchasing a low NOx heater for your facility.
They're Environmentally Friendly
When NO2 and NOx are released, they interact with other chemicals in the atmosphere that is harmful to the environment. The EPA has linked NOx emissions contributing to acid rain, smog, global warming, and smog. By using a low NOx heater, you greatly reduce NO2 pollution in the atmosphere.

They're Safer For Your Employees
According to the EPA, exposure to nitrogen oxides has been found to contribute to respiratory problems and diseases, like asthma. By installing a low NOx heater, you're potentially preventing damage to your employee's lungs.
They're More Efficient
As our low NOx heaters are built using a serpentine coil technology, they have space between the coil tubes which renders them 10 to 15% more efficient that hot oil heaters that feature helical coils.
Unfortunately, there's no one-size-fits-all answer to this question. The overall cost of purchasing new equipment and implementing a new system will depend largely on a number of factors that vary for each different customer.
While we can't tell you exactly what you should plan to spend, we can give you some information on what will impact the price of the equipment you purchase.
Read on to find out what factors will influence how much you will spend on thermal fluid heating equipment for your plant.
The choice between a steam system or a thermal fluid system is governed by the process requirements. The range or process temperature is a deciding factor. If the system’s required temperature is above the freezing point of water (0°C) and below approximately 160°C, the choice is usually steam. However, if the required temperature is above 160°C, thermal fluid may be a better solution. Thermal oil heater systems can be designed with maximum operating temperatures to 325°C.
All thermal fluids expand as they are heated. The amount of expansion is based on the operating temperature, system volume and the coefficient of thermal expansion of the fluid. An expansion tank must be provided to accommodate the increased system volume at operating temperature.
NOTE: All fluids expand at a different rate.
A thermal fluid system is a closed loop using mineral or synthetic oil as the heat transfer fluid. These systems operate at elevated temperatures while maintaining low system pressures. Fluid is circulated within the heater tubes and flue gases heat the fluid.
The life of the heat medium oil for thermal oil heater is related to the operating temperature, and the life is shorter when the operating temperature is high.After half a year, the heat medium oil is used for sampling every 2-3 months. When the flash point of the heat medium oil changes by more than 20%, the acid value is less than 0.5 mgKOH/g, and the residual carbon is less than 1.5 wo/o, when the color of oil becomes dark, it indicates that it has failed and needed to be replaced.The relationship between heat transfer oil life and temperature is shown in the following table: (unit, year) 360℃ 360℃

1. They are all a heat conversion device. The heat transfer medium they use is different. The water used in the steam boiler is heated to become steam. The heat transfer medium of thermal oil heater is heat medium oil. The heat is transferred to the heated substance by the heat medium oil.2. When a higher heating temperature is required, such as 280 degrees, the steam pressure of the steam boiler should reach 7MPa or more, and the process piping and heat exchange equipment must also withstand the same pressure. The equipment cost is high and dangerous. Thermal oil heater provides a temperature above 280 degrees, but the pressure is lower than 1MPa.3. The temperature of thermal oil heater can be accurately controlled within 3 degrees and the temperature of the steam changes greatly.4. Thermal oil heater is used alone, the exhaust gas temperature is higher, and the thermal efficiency is lower than that of the steam boiler. However, if used in conjunction with a steam boiler, the
