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:

When to Deploy QUANTUM Controller
What's Included (NAR SKU: N/A):
- 1 × QUANTUM Controller module (3 oz) — the temperature regulation brain of the QUANTUM Blood & Fluid Warming System
- Temperature regulation in far-forward blood transfusion: The controller modulates energy delivery to the heating element in real time, maintaining 100.4°F (38°C) output regardless of input temperature and flow rate variation.
- Replacement controller for existing QUANTUM systems: A standalone replacement for providers whose controller has been damaged, lost, or reached end of service life.
- Multi-system unit-level programs: Additional controller unit for medical teams running more than one QUANTUM system simultaneously during mass casualty operations.
- Training asset separation: A dedicated training controller prevents training wear from reducing the service life of operational controllers.
- Combat casualty resuscitation during TACEVAC: At only 3 oz, the controller adds negligible weight to a medic loadout and provides closed-loop temperature regulation throughout the transport phase.
Field tip: The controller constantly monitors system status — audible alerts are active by default. The QUANTUM Controller is the only blood-warming system cleared by the FDA to allow disabling audible alerts for covert tactical operations. Use this feature when noise discipline is required during patient treatment.
How QUANTUM Controller Compares
QUANTUM Controller vs. complete QUANTUM System: The complete QUANTUM system includes a controller as part of the base kit. This listing is a standalone replacement controller — for operators replacing a damaged unit or adding a second controller to expand system capacity.
QUANTUM Controller vs. QUANTUM Battery: The controller (3 oz) manages the temperature regulation logic and monitoring. The battery (16 oz) provides the power. Both are required for system operation — the controller without the battery cannot warm; the battery without the controller cannot regulate output temperature safely.
QUANTUM system discontinuation note: NAR has announced QUANTUM discontinuation. Replacement controllers are available while stock lasts. Providers maintaining QUANTUM systems should stock replacement controllers now before supply becomes limited.
QUANTUM Controller — Frequently Asked Questions
Q: What does the QUANTUM Controller do?
A: The QUANTUM Controller is the central processing unit of the QUANTUM Blood & Fluid Warming System. It continuously monitors the temperature and flow rate of the fluid in the Thermal Transfusion Set (TTS-B) and modulates power delivery from the QUANTUM Battery to maintain a normothermic output of 100.4°F (38°C ± 2°C).
Q: How much does the QUANTUM Controller weigh?
A: The QUANTUM Controller weighs 3 oz (approximately 85 grams), making it the lightest component in the three-part operational system (controller + battery + TTS-B = 22 oz total operational weight).
Q: Can audible alerts be disabled on the QUANTUM Controller?
A: Yes. The QUANTUM Controller is the only portable blood-warming system cleared by the FDA to allow disabling of audible alerts — a feature designed specifically for covert tactical operations where noise discipline is critical during patient treatment.
Q: Is the QUANTUM Controller a standalone replacement part?
A: Yes. SKU available through MED-TAC International for replacement procurement. Note that with QUANTUM system discontinuation announced by NAR, replacement controllers will become scarce over time — stock spares now.
Q: What controller battery or power source does it use?
A: The QUANTUM Controller draws power from the QUANTUM Battery (35-0002) — it does not use an internal battery. The Controller and Battery together form the core power and regulation assembly of the system.
