We attempt to dehumidify our screen room (can hold it down about 45-50% on high heat/humidity days) but our exposure unit (small bank of tubes style) gets hot FAST. When it's above 80 outside it's often 90+ in the screen room and we can only burn about 4-6 screens before the whole exposure unit is too hot (emulsion starts to stick, transparent tape melts (so we started using heat resistant transfer tape to hold the positives), and exposure time changes as the emulsion COOKS).
We'd prefer not to put a fan on it as it is the same room the screens dry in and we'd like to not stir up any dust. Any pointers?
