Centrifuges are commonly used in medical research for protein, genetic and cellular analysis. Centrifugation involves spinning samples at a fast rate to build up physical forces and release heat. Dense components migrate away from the center axis, while less dense components migrate towards the axis. Depending on the sample, a centrifuge tub must maintain a temperature between 0°C and 40°C while working in ambient temperatures of 23°C to 30°C. Heat load cooling requirements can range from 30 to more than 150 Watts depending on the centrifuge type and size. The highly reliable Ceramic Plate (CP) Series Peltier cooler from Laird Thermal Systems enables centrifuge manufacturers to resolve thermal design challenges associated with low profile form factors, while also providing vibration resistance and low noise operation.
The CP Series is a rugged, compact Peltier cooling module product line designed for higher current and larger heat-pumping applications like centrifuges. Placed underneath the centrifuge tub to cool from the bottom, the CP Series direct-to-air configuration offers a maximum cooling power of up to 125 Watts with a temperature difference (Delta T) of 67°C. The CP Series is available in a wide range of heat pumping capacities, geometric shapes and input power ranges to meet centrifuge requirements.
With no moving parts, solid-state Peltier coolers significantly reduce maintenance, operation and total ownership costs. Peltier coolers offer high reliability, no operational noise levels and are robust in high-vibration applications like centrifuges.
“Compared to compressor-based technologies, Peltier cooling is more compact, cost-effective, reliable and environmentally friendly,” said Andrew Dereka, Product Director at Laird Thermal Systems. “The CP Series Peltier cooling modules are designed for indoor refrigeration applications, which makes it ideal for cooling centrifuges.”
Laird Thermal Systems has decades of experience in providing cooling solutions for a wide range of medical and analytical applications. With an extensive product breadth and diverse portfolio, Laird Thermal Systems offers advanced Peltier modules, Peltier assemblies, and controller units.
