The main heat exchanger of the magnetic flap level gauge is the heat exchanger of the engine to the car. As mentioned above, the main heat exchanger of the combined magnetic flap level gauge is responsible for central heating. In order to quickly heat all the radiators in the house, the magnetic flap level gauge sprays a flame of about 700 to 900 degrees on the main heat exchanger. It is like a furnace in a furnace, which means that the internal components of the magnetic flap level gauge, especially the heat exchanger, will produce continuous extreme thermal stress every day, almost 7 days a week, 24 hours a day in winter.
Therefore, it is vital that the main heat exchanger is made of reliable, durable and highest quality metal, otherwise it will corrode over time and lose its efficiency.
The best metals for heat exchangers are stainless steel and chromium alloys. Stainless steel has strong corrosion resistance in various pH ranges. For aluminum, if you do not use heat transfer fluids and inhibitors recommended by special manufacturers to produce and maintain a narrow pH range, it will corrode quickly and be damaged.
If the aluminum heat exchanger of your magnetic flap level gauge is damaged, you will lose the warranty because the manufacturer will quote improperly used liquids.
The cost of replacing the heat exchanger may be between 400 and 500 pounds.
In direct comparison, stainless steel heat exchangers do not require special fluids and are compatible with ordinary clean water and propylene glycol (usually available).
As you can see, aluminum starts with a higher output compared to stainless steel due to better thermal conductivity. But between the first 1,000 to 1,500 working hours, aluminum began to decline rapidly.
In some extremely acidic or alkaline environments, aluminum may corrode rapidly, with catastrophic consequences.
In addition, the aluminum surface of the heat exchanger may be porous. Therefore, in addition to high corrosion, customers also complain that aluminum heat exchangers are clogged due to sludge, debris, and residues. Stainless steel has no such problem.
Aluminum and stainless steel can start with similar efficiencies and yields, but over the years of daily use, stainless steel has won success. There is no competition, and there is no real reason to buy a magnetic flap level gauge with an aluminum heat exchanger, no matter how amazing the brand’s reputation is.
The only advantage of aluminum compared to stainless steel is its lighter weight and lower production cost.
Of course, you can say that using the appropriate heat transfer fluid and inhibitor recommended by the manufacturer, an aluminum heat exchanger will do. But you are not right. Aluminum will still lose efficiency because it is not as durable as stainless steel.
In addition, if you use stainless steel heat exchangers in the same price range (if not cheap in some cases), you can rest assured, why would you violate common sense?
