Thermosafe
The Thermosafe Air Heating System passes a steady stream of warm air
across the central hole of a Heated Metal Insert. Air passes through a
filter, fan and heater before exiting from the nozzle located close to the
central hole of the Heated Metal Insert.
Note: It is normal for the air heater enclosure to become warm when in
use.
The temperature of air exiting the nozzle is controlled to a high degree of
accuracy, with the quantity of air preset to an optimum value to give the
most consistent heating across the central hole of the metal insert. As
with most microscope based heating systems, sample temperature will
be affected slightly by ambient conditions.
The system has been designed to not interfere with the normal operation
of the manipulation system. Consequently, all components of this system
are located underneath the baseplate, with the exception of the filter
which is located at the rear of the baseplate for ease of access.
Refer to the Care and Maintenance section for requirements to change
the Thermosafe Air Heating System filter (Figure 11-2 on page 67).
The Thermosafe Air Heating System has been designed to
minimise audible noise and vibration, which should not be
noticeable under normal operating conditions. In the event of
audible noise or vibration from the system, contact RI for support.
Heated Stage Plate Only (Modes 4 and 5)
The Integra 3 can be configured to operate only the Heated Stage Plate.
This is typically only required when using the Integra 3 with an externally
controlled stage insert not manufactured by RI.
When using an externally controlled heating stage insert Mode 4 enables
the Heated Stage Plate setpoint temperature to be adjusted between 30
and 45°C.
When using an externally controlled heating/cooling stage insert, Mode
5 enables the Heated Stage Plate setpoint temperature to be adjusted
between 30 and 45°C or switched off.
