1.7 HX2 Rating Charts
To select an HX2 the steam pressure (PSIG) available, amount of water (GPM) to be
heated, and amount of heating (°F) to be done must be known. Heating is commonly
specified in increments of 80 °F (40 °F to 120 °F) or 100 °F (40 °F to 140 °F).
The first step is to locate the correct chart from the four that follow. Next locate the
appropriate Steam Supply Pressure available (PSIG) along the X-axis, and the amount of
water to be heated (GPM) along the Y-axis. Where the two intersect, find the rating
curve corresponding to those conditions. If this intersection lies between two rating
curves, choose the larger unit (higher curve).
Notes:
1. For copper-nickel tubes, de-rate the copper tube ratings shown by 20%.
2. The ratings curves shown assume a tube bundle fouling factor of 0.00025 (hr. x ft 2
x °F / BTU).
3. For applications with water as the heating source, contact RECO USA Sales
Department.
