The use difference between round heater and flat heater in Deep Fryer/Open fryer:

The flat heater has large contact area and high thermal efficiency. The flat heater of the same size is smaller than the surface load than the round heater. (The smaller the surface load of the heater, the better the stability).

The flat heater has a large heating area, which is not easy to destroy the oil and can prolong the use time of the oil

A Chicken Fryer/Deep fryer only needs one flat heater to reach the power required by customers. The round heater may need to use multiple combinations to meet this requirement. The flat heater has simple structure, convenient installation and easy cleaning, which is the reason why the world famous fast food brands choose the flat heater Fryer.
