Hot Water Coils
Fluid Coils
These tube-and-fin heat exchangers are key to heating systems, transferring heat from hot water to cold air. Hot water coils typically have 1–4 rows of tubes with entering water temps between 120°F to 180°F.
Replacement fluid coils for hot water, low temp hot water, and glycol applications. Available with Freeze Block™ Technology.
Built for the job
Options that match the application
If the original design is not always the right answer, we can help adjust the replacement around current operating conditions.
- Protective coatings for corrosive environments
- Custom fin spacing
- Connection changes and orientation changes
- Sectional coils for tight access
- 15, 10, and 2-day expedite options when available
