Where HTC025B Fits
Best applications for this model
HTC025B is sized for cabinets where the internal heat load is in the range that 25 W/°F can move at your available temperature differential. As a quick rule of thumb, multiply 25 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 500W; at a 30°F ΔT, 750W.
Watch: Cross Flow vs. Counter Flow
Common use cases
Outdoor telecom RTUs, fiber distribution cabinets, small-cell shelters, pipeline SCADA panels.
Voltage fit
Direct connection to −48V telecom plant . No inverter required. Battery-resilient cooling.
