Specifications:

Tube-fin heat exchangers consisting of 1-12 rows of tubes passing through sheets of formed fins, bonded through tube expansion.
It come with various tube, fin, and material options. As warm air passes across the coil and contacts the cold surface, heat transfers from the water flowing through the tubes to the air entering the coil. Have many different applications. Coil Specialist, Inc. Has the capabilities to provide you with the exact chilled water coil to meet your rigorous specifications.

Our coatings are numerous and range from E-Coating that can withstand the harshest environments to pre-coated fin stock that can withstand 1000-2500 hours salt spray depending on needed protection. The versatility of Coil Specialist Inc. Allows us to provide you with virtually everything you need. Call us today and see how we can help you.

How Heat Transfer Works

1. Heat transfer occurs when there is a difference in temperature between two mediums
2. Heat will travel from the hot source to the cold source.
3. The rate at which the heat transfer occurs at is determined by many factors such as the heat conductivity of the two materials and the difference in temperatures of the two mediums.
4. Heat transfer occurs when the materials are moving against each other.
5. It have significantly good heat transfer rates because they use metal plates which have high heat conductivity rates and the plates are extremely thin.
6. The plate heat exchangers also achieve high amounts of heat transfer through convective forces with both working fluids.
7. With large temperature differentials, great amounts of heat transfer can be achieved. <o: P>
