OVEN OPERATION
Oven
The LCC/LCD2-14PT-3 Series pass-through oven is a class 100 clean room oven with
HEPA (High Efficiency Particulate Air) filtration. This oven is ideal for processes where
minimization of contamination is essential.
Forced convected airflow provides rapid uniform distribution of heat. A HEPA (High
Efficiency Particulate Air) filter is mounted in a stainless steel frame in the supply
plenum. These filters are 99.97% effective in filtering 0.3 micron particles prior to filter
burn-off.
The cooling/exhaust fan is controlled on/off by an event relay in the Protocol Plus
Control. The cooling fan is used for rapid cool-down at the end of the process cycle, or
to maintain low temperature setpoints during process cycle. It may also be turned on at
the start of a process cycle to assure that starting temperature is less than 70°C.
The oven has a type 304-2B stainless steel interior. All interior seams are continuously
welded on the insulation side. This protects the work chamber from contaminated air
and permits chamber washing without damaging the insulation. Interior ductwork may
be easily removed for cleaning. Heater frame, fan wheel and motor shaft are
constructed of stainless steel.
Non-sterile side controls are mounted on the front of the oven for easy operation and
readability. The EMO (emergency off) switch and indicator lights are mounted on the
control panel on the sterile side. Two electropolished stainless steel wire shelves are
provided. The shelves are removable and adjustable on three inch centers.
