Deionized Water Heater Selection Guide

Sizing Calculations: Illustrated below
Required kW = 0.264*(Flow in GPM)*(Temp Delta in °C)

Conversion Calculations:
GPM = LPM / 3.8
°C = 5/9*(°F - 32)

Heater Sizing Formula Example
Ambient Water Temp = 25 °C
Desired Process Temp = 70 °C
Temperature Delta = 45 °C
Required kW = 0.264*(4 GPM)*(45 °C) = 47.5 kW

For optimal temperature response and to compensate for seasonal changes in ambient water temperature, we recommend adding 20% excess heating capacity.

47.5 kW(1.2) = 57 kW >>> Trebor recommends a 60 kW heater for this application
