Warming blood to a safe, consistent temperature isn't a fixed heat setting — input fluid temperature and flow rate are constantly changing. A static heater either undershoots cold blood or overshoots a slow drip. The QUANTUM solves this with a closed feedback loop.
What holds 100.4°F output whether the input is 39°F blood or a room-temp crystalloid at 200 mL/min?
The controller continuously reads temperature feedback from thermistors integrated into the thermal tubing wall and dynamically adjusts power delivery from the 44V battery to hold target output (100.4°F, 38°C ± 2°C) regardless of input temperature or flow-rate swings from 2 to 200 mL/min. Setup is deliberately simple — one cable to the battery, one to the tubing, neither with a plug orientation. On connection the system self-tests and signals readiness via a status sequence (green flash to blue flash to solid green) within 24 seconds. For tactical environments, it is the only FDA-cleared fluid warmer that permits disabling audible alerts.
Why This Component
Dynamic Control Loop
Reads tubing-wall thermistors and adjusts battery power in real time to hold output on target.
3 oz, Ruggedized
The lightest element of the system, built to take a beating in the aid bag.
No Wrong Connection
Both cables connect without plug orientation — nothing to fumble under stress.
Tactical Alert Silencing
The only FDA-cleared fluid warmer that lets you disable audible alerts.
Completes The System
A standalone replacement for the controller, or a spare alongside batteries — so no single component failure sidelines a system:
