Specifications
Weltem Portable Air Conditioners feature spot cooling for large areas
where cooling of the entire area is not practical. A dedicated
spot cooling thermostat controls the unit in this application.
These air conditioners can also be used in smaller areas
for room cooling.
A control panel provides ease of use and contains a self-diagnostic
function and display, showing operating modes, room and
set temperatures, and faults.
If an abnormal operation occurs, a visual display of the fault is shown.
Caster wheels are included for easy portability.
Suitable applications include: a factory or work place, industrial kitchen,
computer room, emergency cooling, outdoor event, etc.
