Thermo Scientific Heratherm IMP 4-7
Safety Devices
The refrigerated incubators are equipped with the following safety features:
• a sample protection feature that safeguards the samples against destruction through
overheating in case of controller failure;
• dual sensor: if one sensor fails, the other will take over.
• an overheat protection cut-out feature class 2 (TWB), according to DIN 12880, that shuts
down the refrigerated incubators IMP completely when excessive temperatures occur in
the workspace;
• an alarm relay that is energized, along with audible and visual alarms, to indicate errors
encountered during operation;
• dual fuses rated at 15 amperes.
Work Space Atmosphere
To ensure undisturbed operation, the ambient temperature in the operating room must be at
least 18 °C (64.4 °F).
The Peltier element controls the work space temperature of the refrigerated incubator from
5 °C (41 °F) up to the maximum of 70 °C (158 °F).
Sensing and Control System
The PT 100-type sensor for the control of the work space temperature and for the thermal
protection is installed on the bottom of table-top refrigerated incubators and in the top of
floor stand refrigerated incubators.
