Chemical Heater Selection Guide
IQ Chemical Heaters from Trebor® are used in both single
pass and recirculation heating systems. The graphs and
table below can help in sizing your heater for the application.
It is recommended that all heaters are oversize 20% to allow for
control. As with any general reference data, accuracy should be verified
with creditable sources.
For chemicals other than water – Select the X factor related to the
fluid from the Table One below. The Change in
Fluid Temperature per Pass can be calculated by dividing the temperature
change of water into the X factor and looking up the flow / heater power
on Graph One above.
For chemicals other than water – Select the X factor related to the
fluid from the Table 1 below. The Time to
Increase Various Tank Volumes can be calculated by multiplying the
temperature change of water into the X factor and looking up the time /
heater power on Graph 2 above.
