A thermal fluid heater is a device that makes use of a liquid phase to employ heat energy to perform a process. Heat mediums like water, thermal oil or glycol are used for the heat generation within a closed loop arrangement. These heaters are a good choice for an industrial setup and help to avoid the development of frost, corrosion and scale formation. The excellent thing about these heating units is its easy maintenance and simple operation. There are multiple industries which can make use of these heaters. Some of them are the Packing companies, plants for food processing, processing plants for timber, companies of paper production, textile processing units, manufacturers of automobiles and a lot more.
Before you opt for a particular thermal heater, it is essential to keep specific factors in mind. The tips listed below can help you in this.
1. Requirements of Temperature:
Every thermal fluid heater is differently designed to work in a different range of temperatures. It includes the minimum and the maximum bulk temperature. Select a thermal fluid heater in accordance with your requirement. For example, you can opt for this heater which can reach up to 700 degrees or even 350 degrees. The choice totally depends on the need of the temperature.
2. The efficiency of the Thermal:
Thermal fluids which have a viscosity on the lower side can display the coefficients of heat transfer which are on the higher side at moderate temperatures, almost 350-degree fluid temperature in bulk. They also provide the best possible protection against overheating the fluids of the secondary nature which tend to be sensitive to temperatures which are high. The outlet for the hot oil heater can be set at a lower point with a fluid which is more efficient and less viscous. This offers the required bulk temperature in the secondary fluid.
3. Pumping Ability:
The job sites where the temperatures can drop below the freezing point, the temperature range needs consideration in such places. Adequate pumping capacity is essential to perform under these weather conditions. There is a possibility that the thermal fluid freezes to a block if not chosen in a right manner.
4. Requirements of the Environment:
Thermal fluid heaters that can adhere to the requirements of the environment is necessary for ensuring the longevity of the same. Also, considering the temperature requirements in accordance with the environment for the insulation size is essential. As mentioned, the external temperature also matters for sizing this heater. Heaters which are installed at an altitude require a close inspection of the burner so that enough and more air is available for the required combustion. Those heaters which are installed in an environment can lead to corrosion and require oil coating over all the equipment so that these can be protected from rust.
5. Check out the Code Requirements:
A specific code requirement is essential for every application. Most often the NFPA (National Fire Protection Association) covers almost all the requirements. To determine if any more of these code requirements are essential can be checked with the local authorities.
6. The system for Piping:
The system temperature and pressure requirements should be met by the components. Material like cast steel, carbon steel, ductile, iron, and stainless steel work apt for these hot oil systems.
Finally, before opting for the thermal fluid heaters do consider the price factor. The price of the fluid depends on the pumping ability, thermal efficiency and the temperature requirements of the place. If a system is designed to accommodate to the temperature that is on the lower side, filling the system might work out reasonable.
