PERFORMANCE DATA — 549B, 549C (cont)
ELECTRIC HEATING CAPACITIES — 549B036-120 AND 549C024-060 (cont)
*Two heater packages required to provide kW indicated.
NOTES:
1. The rated heater voltage is 240 and 480 v. If power distribution voltage varies from rated heater voltage, heater kW will vary accordingly.
2. To determine heater kW at voltages other than those shown in table, use the following formula:
Heater kW
new
= Heater kW
rated x
(unit power distribution voltage/rated heater voltage)
2
As an example:
For a 16 kW heater rated at 240 v with a power distribution voltage of 215 v
kW
new
= 16 kW (215/240)
2
kW
new
= 12.8 kW (rating at 215 v)
MULTIPLICATION FACTORS
NOTE: The following equation converts kW of heat energy to Btuh:
kW x 3.413 = Btuh.
EXAMPLE: 34 kW (at 230 v) heater on 208 v
= 34.0 (.751 mult factor)
= 25.5 kW capacity at 208 v.
