SDA-130-24-02 Direct-to-Air

The SDA-130-24-02 Direct-to-Air thermoelectric assembly is a high performance thermoelectric based heat pump. It is designed to temperature control small chambers used in medical diagnostics or sample storage compartments in analytical instrumentation. This unique, patent pending design offers a high performance hot side heat dissipation mechanism that convects heat more efficiently than conventional heat exchanger technologies. The design utilizes custom thermoelectric modules to maximize cooling capacity and premium grade fans to reduce noise.

Cooling for Centrifuges

To separate fluids, the centrifuge spins samples at a fast rate, resulting in heavy components to migrate away from the center axis and lighter components to migrate towards the axis. Centrifuge devices are widely used tools in food processing and medical research for cellular, genetic and protein analysis. When designing laboratory and medical centrifuges, several design challenges must be considered. 

Peltier Cooling for Refrigerated Centrifuges

 

Introduction

Centrifugation is a process that separates mixtures through centrifugal force. Centrifuges are commonly used in food processing and medical research for protein, genetic and cellular analysis. In medical laboratory settings, centrifugation involves spinning medical samples at a fast rate to filter or concentrate substances based on differing densities. Dense components migrate away from the center axis, while less dense components migrate towards the axis.

Heating and Cooling of Incubator Chambers

Since proteins are extremely sensitive to environmental deviations, a temperature difference by as little as 6°C from the body temperature of 37°C, have a negative impact on cell health. If too cold, cell growth slows and if too hot, sensitive proteins begin to denature. Not only temperature needs to be controlled, also humidity, carbon dioxide and oxygen levels are important factors. Due to the limited space constraints within incubators, thermal solutions must have a compact form factor. Incubator manufacturers also face challenges related to airflow, moisture, dust and ease of cleaning.

Thermoelectric Cooling for Outdoor Kiosks

Introduction

Outdoor kiosks have grown in popularity in a wide variety of applications and sectors, including banking, entertainment, retail, showrooms, industrial and education. You see kiosks everywhere, from banks and airports, to theme parks and train stations. Being located outdoors, kiosks and the sensitive electronics they contain are subjected to extreme temperatures, from the cold of winter to the heat of summer. Ambient temperatures can exceed 40°C or below 10°C. Heat loads for the electronics themselves can range from 20 to more than 200 Watts.
