Solutions & Product Series
Andely manufactures custom-built hydronic heating coils, chilled water cooling coils, steam coils, and heat exchangers for commercial and industrial HVAC applications. Each coil is built to the engineer’s specification — matching face dimensions, row depth, fin spacing, connection size, and pressure rating to the exact requirements of new installations and replacement projects.
Hot Water Heating Coils
Hydronic fin-and-tube coils for AHU and duct heating
- Copper tube / aluminum fin construction — standard and high-efficiency fins
- 1-row to 6-row depth — designed to BTU requirement
- Face sizes from 6″×6″ to custom oversized for industrial AHUs
- Header material: copper, steel, or stainless for system compatibility
- Threaded and flanged supply/return connections
- Tested to 300 PSI working pressure before shipment
Chilled Water Cooling Coils
Multi-row cooling and dehumidifying coils for air handling
- 4-row to 8-row configurations for sensible and latent cooling
- Drainable coil design with sloped tubes for complete drainage
- Integral drain pan options for retrofit and replacement installations
- Copper tube / aluminum or copper fin for corrosive environments
- Face velocity design up to 550 FPM for standard HVAC duty
- Pressure tested — 300 PSI hydraulic, 200 PSI working pressure
Steam Coils
Steam distributing and non-freeze steam coils for air heating
- Steam distributing coils prevent freeze-up in cold outside air applications
- Inner tube distributor design ensures full coil warming before air flow
- Suitable for primary and secondary steam systems 15–150 PSIG
- Stainless steel inner distributor for steam purity requirements
- Pitched supply header for proper condensate drainage
- Used for preheat coils on 100% OA air handling units
Replacement & Retrofit Coils
Exact-match replacement coils for existing AHU units
- Match to existing coil face dimensions, connection locations, and casing
- All major AHU brands: Trane, York, Carrier, McQuay, and custom
- Improved fin efficiency upgrades available on replacement
- Quick turnaround — coil drawings supplied for approval before fabrication
- Casing and frame options to match existing AHU coil section
- Coordinate with site measurements for guaranteed fit
Why Choose Andely
Key Advantages
Built to Specification
Every Andely coil is manufactured to the engineer’s exact face size, row count, fin pitch, and connection requirements — ensuring proper BTU performance and a drop-in fit in the AHU or duct section.
Replacement Expertise
Andely specializes in replacement coils for existing air handling units — matching OEM dimensions so retrofits install without structural modifications to the existing casing or supports.
Thermal Performance
In-house coil selection software generates certified performance data — capacity, air pressure drop, water pressure drop, and leaving conditions — for submittal and engineering review.
Construction Quality
Copper tube mechanically expanded into aluminum or copper fins ensures permanent tube-to-fin bond, minimizing thermal resistance and maintaining performance throughout the coil service life.
Fast Lead Times
Standard and replacement coils shipped in competitive lead times — with expedite options for emergency system outages and planned shutdowns where coil delivery is on the critical path.
Pressure Tested
Every coil is hydraulically pressure-tested before shipping — no leaks on startup, no delays, and no expensive re-entry into mechanical rooms to address quality issues.
