The CardioQuip Modular Cooler-Heater (MCH) Series brings accurate and efficient temperature control to the operating room. Its next-generation touchscreen interface, software and hardware safety features, conscientious design, and intuitive operation have made it one of the most talked-about perfusion products on the market.
Choose the full-size MCH-1000(i) for best-in-class performance at an economical price or choose the compact MCH-1000(m) to pack MCH performance into tight places.
Safety is foremost in the MCH Series design. Compliance to current standards, smart alarms, hardware and software temperature overlimit controls, and integrated system monitoring ensure patient safety and worry-free operation.
Some of our competitors use a Closed Water Path design, with enclosed tanks that are difficult to inspect and clean. The internal air pockets in these systems give dangerous microbes a place to hide, away from disinfectants. The CardioQuip MCH employs an Open Water Path design.
The internal plumbing is completely filled with water, with no hidden air pockets to harbor microbes, and sections of clear tubing are strategically located to make it easy to check for biofilm. The main water tank is fully accessible for inspection and cleaning, and the straightforward MCH quarterly cleaning procedure takes less than 30 minutes.
Adaptive Temperature Control monitors the set and actual water temperatures, evaluates the rate of temperature change, and applies only the amount of heating and cooling necessary to achieve the set temperature without overshoot. This reduces the overall energy consumption of the MCH, and makes the most efficient use of the available ice.
In testing*, the MCH-1000 used up to 25% less ice and required up to 70% less operator intervention then competing heater-coolers.

The MCH Series uses a bright TFT color LCD to provide up-to-the-second information and quick temperature response. Use the +/- buttons for 0.1℃ adjustments. Touch the setpoint, and a numeric keypad appears to allow quick adjustment—or use the custom presets to store common temperature settings for ultra-fast access. Use the included 15’ (5m) tether to put the touchscreen right where you want it.
Optional modules increase MCH functionality. The Refrigeration Module adds ice making capability to the MCH-1000(i), and the Cardioplegia Shared Channel Module is a perfect complement to cardioplegia delivery systems like the Quest MPS™. Add a Thermo-Electric Cooling (TEC) Module to the MCH-1000(m),and it’s the only self-cooled compact cooler-heater on the market.
What’s wrong with dual-channel designs?
The CardioQuip team includes one of the inventors of the original dual-channel cooler-heater, so they know a few things about the pros and cons of dual-channel technology. Dual-channel systems, while convenient, suffer from multiple inherent limitations.
Temperature fluctuations. Both channels share a common ice bath. If one channel is running normothermic, and the other is running cold cardioplegia, then every time the normothermic side needs a little cooling, it dumps hot water into the ice bath. This can cause disruptive temperature fluctuations in the cardioplegia channel.
Poor heating performance. Both channels share one 20 Amp electrical circuit, which can only support 1600-1700W of heating. To heat two channels at once, the device must “pulse” the heaters, alternating between channels to avoid drawing too much electrical power. This significantly reduces the overall heating performance.
Maintenance issues. Dual-channel units are more complex, and tend to require more frequent maintenance. Even if just one channel is down, the entire unit must be taken out of service, in the interests of patient safety and litigation avoidance. In addition, many dual-channel devices have a closed water path design, making them difficult to clean and prone to internal microorganism growth.
The CardioQuip MCH, with its straightforward single-channel and dual-shared channel design, avoids these limitations.
