Where HTC015B Fits

Best applications for this model

HTC015B is sized for cabinets where the internal heat load is in the range that 15 W/°F can move at your available temperature differential. As a quick rule of thumb, multiply 15 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 300W; at a 30°F ΔT, 450W.

Watch: Cross Flow vs. Counter Flow

Common use cases

Outdoor telecom RTUs, fiber distribution cabinets, small-cell shelters, pipeline SCADA panels.

Voltage fit
