Compatibility
Air handler (AHU) capacity compatibility
CH-NREH10KW (10kW) is approved for the following R454B Multi-Position AHU sizes:
| AHU Capacity | 18K | 24K | 30K | 36K | 48K | 60K |
|---|---|---|---|---|---|---|
| 10kW Heater (CH-NREH10KW) | Y | Y | Y | Y | Y | Y |
Because the 10kW kit is approved across 18K–60K AHU capacities, it is commonly selected for larger ducted air handler sizes.
System tonnage reference (electric heat availability)
For the listed R454B Multi-Position AHU models below, 10kW auxiliary heat is available from 1.5–6 ton.
| Electric Heater | 1.5 ton (18,000 BTU/h) |
2 ton (24,000 BTU/h) |
3 ton (30,000 BTU/h) |
4 ton (36,000 BTU/h) |
5 ton (48,000 BTU/h) |
