MAQUET Jostra HCU 30

Maquet Jostra HCU 30 Heater/Cooler System

The Maquet Jostra HCU 30 Heater/Cooler System is engineered to circulate temperature-regulated water through heat exchange circuits during cardiopulmonary bypass procedures lasting up to 6 hours. Designed for precise warming or cooling, the HCU 30 delivers controlled water temperatures for use with oxygenators, heat exchangers, or hyper-hypothermia blankets. With an adjustable temperature range from 1°C to 40.5°C and a 26-liter water tank, the system ensures optimal thermal management while maintaining patient safety through an integrated internal safety system that prevents water temperature from exceeding 41.3°C.
