INCUBATOR /OVEN/ FURNACE – SElECTION GUIdE
STEP 4: Control System and data Collection
Do you require simple or complex heating schedules or do you just need your piece of equipment to maintain
a constant temperature. All of our equipment use PID microprocessor controllers, however on some of our
ovens we can provide controllers that simply maintain a given temperature, or others that can heat up to
given temperature via a series or ramps and dwells. Some of the more sophisticated controllers use complex
PID algorithms to control the temperature and can follow programmed heating schedules very accurately.
We can also equip most pieces of equipment with chart recorders so that you can check
how the temperature varies according to your process without actually having to be there.
Alternatively, some controllers can be hooked up to RS232/RS485 ports, so that they can
be connected directly to a data logger or computer to collect this information.
STEP 5: Special Requirements
While we have endeavoured to construct the interior linings of our ovens and incubators out of stainless steel
to make cleaning easy and the interiors resistant to chemical attack, it may not always be the solution for all
situations. For this reason, you should always let us know what you are intending to put in the oven or incubator
before purchasing in case your process require any special construction materials.
Furnace linings are made from high alumina compositions, which are generally inert and hard wearing,
although may be susceptible to chemical attack from certain species. Again, you should let us know what
you are going to be heating in your furnace before purchasing to ensure you are getting the best furnace
for your application.
When dealing with the heating of materials that produce vapours (e.g. water vapour etc), it may be an
advantage to fit an exhaust fan to remove these gases more efficiently. You may also need to make
arrangements for during these gases out of your laboratory or locating the oven in a fume cupboard.
STEP 6: Options
After having chosen the right piece of equipment for your application, the addition
of some options may make it more functional for your application, e.g:
• Extra shelves, especially if you are working with a large number of smaller samples.
• Viewing windows, useful for checking the progress of a process without upsetting
the temperature within the chamber.
• Lights, for applications requiring UV or day night simulation.
