Understanding the emergence of micro-channel and micro-groove coils

Design differences.
By Jim Wheeler
No Comments

The premise behind “micro-groove” coil construction is to continue with the standard copper-tube and aluminum fin design we all are so familiar with, but do so with smaller internally enhanced tubes that have thinner walls. This reduces the amount of copper, as well as the cost, size and weight of the coils.

Put a charge in it

Noninvasive preventive maintenance is the way to go.
