Description of some advantages of the induction heater “difhemi”

Security

In operation the security is complete, without requiring extra care, due to the physical separation between the heater and the power grid.
The system works dry and is cooled naturally.
The system does not propagate flames and don't sparkles and can heat directly highly flammable and combustible gases.
Can operate in restricted area.
Operates with zero voltage between pipes and power, allowing greater security for heating any kind of fluid, even being conductor (the fluid run off inside the pipe insulated).

Efficiency and reliability

The Electromagnetic Inductive Heating (DIFHEMI) offers better performance compared to heating systems with heaters or steam generators.
Its tubular heating elements (pipes) allow highly efficient heat exchange with high heat transfer coefficients and therefore with reduced wall-fluid temperature differences.
The high efficiency of heat exchange between the wall of pipes and the fluid flowing due to the inductive heating it's currently the electrical machine of the largest existing electrical performance.
The high heat exchange coefficient characteristic of the inductive heater is reflected at a film temperature (wall) extremely reduced; that is, the temperature difference between the fluid and the pipe wall is always very small. This in turn means durability and economy, when used for heating system thermal fluid or synthetic oils.
The extremely low thermal inertia of the Electromagnetic Inductive Heating (DIFHEMI), even in large equipment, allows control of the fluid temperature with precision unattainable by any other type of existing fluid heater.
Although the Electromagnetic Inductive Heating (DIFHEMI) use the electric power to generate heat, it was found that heating in most many applications their use has resulted in higher operating economics.
The induction heating system allows the user to get an economic process with a very precise control and fast response to temperature variations.
The Electromagnetic Inductive Heating (DIFHEMI) proved to be applied in many possible processes, as equipment absolutely more efficient and safe for heating oil ultra-viscous fuel, inflammables and corrosives solutions.

Maintenance

Its form of construction does not need maintenance because of the Electromagnetic Inductive Heating (DIFHEMI) has no moving parts or conventional electrical resistance elements.
Conventional electric heaters and steam boiler systems require high maintenance costs and downtime. DIFHEMI works 365 days/year if required by the process.

Pressure and temperature operation

In the Induction Heater DIFHEMI operation pressures and temperatures are only limited by the type of used fluid. It can work at high temperatures and pressures.

Modular enforcement

The DIFHEMI Inductive heater is more compact if compared with other systems fluids heating, enabling a gain of physical space and great ease of installation.
Its features allow a modular application, simplifying and / or taking advantage of the existing lay-out. The modulation can be by production sector or by specific equipment.

SOME ADVANTAGES OF THE INDUCTION HEATER “DIFHEMI” IN REPLACEMENT OF STEAM BOILER HEATED BY BURNING FOSSIL FUELS.

1. Temperature accuracy and uniformity throughout the fluid and process quality by keeping the temperature constant.
2. Elimination of all maintenance costs, facilities and related contracts. (*Maintenance of oil storage tanks, hydraulic system, fuel nozzles, pressure tank, pressure tank suitability to NR 13, operator for 24h steam boiler, among others.
3. Total safety for the operator and the entire process.
4. Space savings due to the compact form of inductive heater construction.
5. Elimination of water consumption by the boiler, as well as its treatment.
6. Direct fluid heating without the need for a heat exchanger.
7. Due to the working system the heater is anti-polluting.
8. Exempt from waste generation on direct heating of thermal fluid due to non-oxidation.
9. In operation the inductive heater is totally noise free.
10. By heating only the fluid, the use of fuel oil additives is not required.
11. Almost immediate heat availability on Inductive Heater energization due to its very low thermal inertia, eliminating long heating periods necessary for the boiler to reach the set temperature.
12. Ease and low installation cost.
13. Heat-saving advantages with the elimination of steam transport pipes.
14. Heater working pressure equivalent to pump / circulating fan pressure.

The steam system has very low efficiency due to the thermal exchange in the boiler as well as need to lose steam flash (energy + water treated) for condensate to be injected into the boiler.

In the case of thermal oil system has no such losses and hence the replenishment energy to the system should be much smaller than in the steam system. That is why the heater thermal oil system shall have less power than the steam boiler.

SOME ADVANTAGES OF HEATING FUEL OIL, THERMAL FLUID, GASES AND LIQUIDS COMPARED BY HEATING THROUGH OTHER SOURCES AND ELECTRICAL RESISTANCES:

1. Energy saving from 10 till 20%
2. Does not be necessary the heat exchangers, the fluid is directly heating.
3. Best efficiency at thermal exchange due to high degree of the convection heat and extremely low the temperature differential of wall-fluid, avoiding any cracking, carbonization and degradation of the fluid
4. Low temperature working of the pipe wall
5. Avoid the cracking (carbonization) of fluids (fuel oil, vegetable oil, juices, thermal fluid and so on)
6. Does not be necessary to substitute heating resistances, because doesn’t have resistances
7. Higher temperatures and pressures allowed during operation
8. Total security during the operation, due to physical separation between the heater and the electricity grid.

In short , the advantages of DIFHEMI over other fluid heating systems:

1. It is safe because it operates with ZERO voltage between the mains and the equipment because the tubular bundles are isolated from the electrical system,
2. Best efficiency at thermal exchange due to high degree of the convection heat and extremely low the temperature differential of wall-fluid, avoiding any cracking, carbonization and degradation of the fluid
3. Low temperature working of the pipe wall
4. Avoid the cracking (carbonization) of fluids (fuel oil, vegetable oil, juices, thermal fluid and so on)
5. It can be operated in hazardous areas,
6. It needs no maintenance, it has no moving parts, it works 24/7, 365 days/year.
7. It can operate at high temperatures and pressures, as well as at high powers (no limit power, just at size),
8. Compact format and modular installation, it can be installed near the place where heating is needed, saving space.
9. Zero fluctuations in operating temperature, which means, constant temperature during the process.
10. Dry working system and it is cooled naturally.
11. Free from generation of waste in the thermal fluid heating due to non-corrosiveness.
12. Elimination of all maintenance costs, installations and related contracts, as in boilers.
13. Complete safety for the operator and the whole process.
