Noun
/mʌl.ti.pæs ɛər ˈhiː.tər/
A multipass air heater refers to a heating system or device that allows air to pass through multiple times (or "passes") to enhance the heating efficiency of the air. This type of heater is commonly used in industrial applications where maintaining a consistent and high temperature is vital for processes such as drying, heating, or even in HVAC systems.
Frequency of Use: The term is specialized and likely to be used more frequently in technical and industrial contexts (written communication) rather than in everyday spoken language.
The factory installed a multipass air heater to increase the efficiency of their drying process.
La fábrica instaló un calentador de aire de paso múltiple para aumentar la eficiencia de su proceso de secado.
Using a multipass air heater can significantly reduce energy costs over time.

The term "multipass" comprises "multi" from Latin multus, meaning "many," and "pass," derived from Middle English passen, which means "to go by." "Air" comes from Old English æar, related to the invisible gaseous substance. "Heater" comes from the verb "heat," linked to Old English hǣtan, meaning "to make hot."
