The technology uses a heated medical grade stainless-steel coil through which fluids/blood flow and then become warmed. The fluid path is 100% aluminum free, which eliminates toxicity concerns associated with both coated and uncoated aluminum. Our patented, microprocessor-controlled dry warming technology measures the blood/fluid temperature hundreds of times per second to ensure immediate adjustments of the power distribution in accordance with changes in flow. Unlike most warming technologies, our heating apparatus is designed to not exceed 38°C. Our heat transfer process is amongst the most relaxed heat transfer processes in the industry.
