CSZ Hemotherm 400MR Features

The CSZ HEMOTHERM 400MR heater/cooler system is used to lower/raise the blood temperature and/or maintain blood temperature, as required, through conductive heat transfer. The conductive heat transfer on the Sub Zero cooler is accomplished through any type of blood oxygenator/heat exchanger unit, along with the use of a blanket under the patient for the re-warming phase, if desired.

  • Efficient Heating/Cooling: Dual reservoirs double your efficiency. Independent cooling and heating reservoirs permit instant changeover from one bath to the other. Each reservoir has its own control mechanism and temperature display. The efficient pump produces a flow rate higher than any competitor’s units. The Hemotherm lowers reservoir water temperatures at a rate that rapidly produces a significant reduction in blood temperature.
  • Patient Safety: Built-in secondary Hi and Lo safety thermostats and an external circuit breaker which can be reset to enhance the safe design of Hemotherm.
  • Convenient: Ice is not required with this system, eliminating the mess and providing a simple setup. For additional convenience, an optional remote control is available to change and monitor the settings of the Hemotherm from a remote location. Microprocessor control provides an easier, more accurate operation. A large LED readout allows monitoring at a glance. Eliminates the need for calibration.
  • Ease of Use: Mechanical refrigeration means easy set-up, quick response, and minimum clean-up. It eliminates the preconditioning process. Hemotherm takes up just 3.4 sq. ft (0.3 sq. m) of floor
    space and moves easily on conductive swivel casters.
  • Dual Purpose: The Hemotherm may also be used with a hyper/hypothermia blanket to provide
    additional patient cooling/re-warming therapy
