Overview
Coilmen builds custom and replacement DX coils for commercial and industrial HVAC and refrigeration. Each coil is matched to the equipment it serves — dimensions, connections, circuiting, and refrigerant.
DX Coil Solutions
Replacement Coils
Drop-in coils matched to existing units when the OEM coil is obsolete or no longer available.
VRF Coils
Coils built to the manufacturer’s refrigerant flow for variable-load VRF systems.
Multi-Circuit Coils
Face-split, row-split, and interlaced circuiting for capacity staging and redundancy.
Industrial Refrigeration Coils
Coils for low-temperature and industrial refrigeration duty.
Applications
Air Handlers
Built-up and packaged AHU coils
Rooftop Units
Packaged RTU coil replacements
VRF Systems
Variable refrigerant flow coils
Make-Up Air Units

Custom Circuiting
Coilmen builds the full range of DX circuiting patterns — matched to the load profile, coil depth, and refrigerant.
| Code | Circuit Type | Best For |
|---|---|---|
| EN | Standard | Standard cooling loads and straightforward replacements |
| EF | Face Split | Staged capacity and part-load control across the coil face |
| ER | Row Split | Deep coils that need even loading front to back |
| EJ | Interlaced | Balanced refrigerant distribution and low-load stability |
| EK | Interlaced Face Split | Wide turndown and precise control in VRF and variable-load systems |
