Altrix at a glance

Patient warming and cooling can be critical in achieving positive patient outcomes. Altrix provides an exceptional choice for patient temperature management with precision, versatility, and speed; all in one safe, easily operated system that can be used in all clinical settings.

Key features

  • Precise, highly responsive control system
  • Versatile system for all clinical settings from coronary care units to OR settings
  • Fast, easily prompted therapy initiation
  • Easy water management and setup
  • No aerosolization of bacteria from the internal water system
  • Rapid temperature control for precision temperature management treatment



One machine.
One system.


A. Three water circuits

Simple, self-sealing hose ports eliminate water spillage and maximize performance, efficiency, and speed to target temperature. All three water circuits can be individually monitored for ease of use.


B. Removable water reservoir

Therapy setup is simple and easy, and allows for uninterrupted temperature management while adding or refilling water with the translucent, removable water reservoir


C. Ease of mobility 

Altrix was designed with ergonomic support in mind. This usability, alongside its proven durable features, results in one machine that can easily be maneuvered throughout the entire hospital.

Patient graphs

Patient graphs provide information about the patient, target, and water temperature as well as power levels in order to help effectively analyze treatment. 


Situational help

Situational help offers assistance and guidance in the case of an alarm in order to properly educate users as to the cause of the alert and how to correct the situation.


Fast, easily prompted therapy

The user-friendly graphic interface makes it easy to initiate patient therapy with just a few simple taps of the finger. These prompts ensure easy setup, especially during highly critical, low frequency situations.

No aerosolization of bacteria

Since 2015, the FDA issued three safety communications about a potential association between patient infections and water-based heater-cooler devices. Nontuberculous mycobacteria (NTM) might have aerosolized into the operating room from the devices and caused serious illness and death of patients.1-4  Rigorous tests performed by an independent laboratory verified that Altrix, when used and maintained according to manufacturer instructions, does not aerosolize microbes from its water system.


Advanced skin protection

  • Non-gel-adhesive, will not stick to a patient’s skin potentially removing skin upon wrap removal, or leaving adhesive on a patient’s skin. Our wraps are soft non-woven fabric to promote skin integrity.
  • Insulated to prevent condensation, reducing wetness near patient’s skin which is a skin integrity risk.
  • Fits 99% of patients, reducing gaps and enhancing thermal transfer, allowing fewer kinks and areas of pressure on a patient's skin.


Dependable precision

Accuracy in therapy management is critical, which is why Altrix measures patient temperatures every 1.3 seconds. This rapid responsiveness uses thousands of power settings to achieve steady state patient control with ± 0.1° C.*

Universal temperature management

Simplicity is integral in highly critical, low frequency situations. The simple, versatile design of Altrix ensures it can be easily used in all clinical settings, for both traditional and critical applications.


Altrix Wraps

The Altrix wraps were designed with the patient and caregiver in mind. The non-invasive and non-adhesive wraps provide increased surface area contact, helping to reduce air gaps that can occur between surface cooling and warming devices and patients’ skin.


Maximum efficiency

Fast therapy management means Altrix can reach water target temperatures 50% faster, and patient target temperatures 40% faster than Medi-Therm.*
