1. Forced Draft ACHE
2. Induced Draft ACHE
1. Forced Draft ACHE
The most economical and most common style air cooler Cheap Air Jordan Retro , the forced draft ACHE, uses axial fans to force air across the fin tube bundle. The fans are positioned below the bundle thus not exposing the mechanical sections to the hot exhaust airflow.

4. Standards in our finned tube heat Exchangers
1. Counter-Current Flow
From Our Supply, This is the most common in the process industry, It cools the hottest fluid with the warmest air, and the coldest fluid with the coldest air. In other words, the process fluid enters the heat exchanger and passes through the finned tubes at the top of the bundle.
2. Co-Current Flow
This flow pattern is typically used in processes with critical pour points as it provides the highest outlet process temperature control since it has the lowest efficiency. In this pattern the ambient air cools the hottest fluid, and the hottest air attempts to cool the coldest fluid. The shaded arrows to the right illustrate this flow pattern.
