Where HIX045B Fits
Best applications for this model
HIX045B is sized for cabinets where the internal heat load is in the range that 45 W/°F can move at your available temperature differential. As a quick rule of thumb, multiply 45 by your ambient-to-target ΔT to get the maximum heat load (in watts) this unit can handle. For example, at a 20°F ΔT this model removes 900W; at a 30°F ΔT, 1350W.
Watch: Cross Flow vs. Counter Flow
