What does HIX045B mean?

H I X 0 4 5 B
  • H = Heat exchanger
  • I = Industrial series (industrial / utility)
  • X = Cross Flow configuration
  • 045 = 45 W/°F capacity
  • B = 48VDC input

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

Common use cases

5G macro-site cabinets, BEAD broadband fiber huts, edge-compute enclosures, mid-size process control panels.

Voltage fit

Direct connection to −48V telecom plant . No inverter required. Battery-resilient cooling.
