A. UNIT OVERVIEW:
The HemaCool™ is designed to preserve liquid or frozen blood products and medical
supplies. HemaCool™ provides exceptional field storage through its combination of
superior insulation technology and temperature controls based on microcontroller solid-
state electronics.
The
HemaCool™
is portable and self-powered, utilizing internal gel cell batteries. The
system will accept electrical power from multiple sources, e.g. 12-24VDC from batteries
or other sources at the AUX input, solar panels, or a wide range of grid power standards
(any combination of 90–264 VAC and 47–63 Hz line frequencies). The unit is designed
with solar panel lightning protection.
If the unit is fully stocked – and no power is applied [unit off] – it will take more than
two hours for the internal payload temperature to rise to 6°C (43°F) in an ambient
temperature of 49°C (120°F). With the optional thermal barrier in place, the unit is also
capable of chilling five (5) units of freshly transfused blood to 6°C (43°F) within eight
(8) hours.
