A modular replaceable heating or cooling (RTHC) device is disclosed. In embodiments, the RTHC device includes a housing enclosing a forward control section attachable to a rear thermal section. The housing is slotted for removable installation into rails in the interior walls of a galley food compartment. The thermal section includes gel packs of a heatable/chillable temperature storage medium (e.g., polymer gel) enclosed in a membrane for controlled dissipation and air channels to admit circulating air over or through the gel packs to be chilled or heated by the temperature storage medium. The control section includes scroll fans for drawing air into the RTHC device through air intakes for chilling/heating, exhaust vents for returning the chilled/heated air to the compartment, control switches for the scroll fans, and visual/auditory status indicators, e.g., for fan speed, battery charge, or the interior temperature of the compartment.
