What we do

As a leader in advanced thermal management Life Enhancement Technologies, Inc. (LET) has developed a line of personal cooling products to meet the challenging needs of medical, military, industrial and consumer applications.  With our patented technology originally designed for cooling astronauts, LET can protect individuals from extreme heat stress to simply maintaining a desired temperature.  Whatever your personal cooling need, we are sure to have a cooling solution for you.

Background

The entire line of microclimate systems and products from LET are a direct spin off from NASA technology.  In the 1960's, NASA discovered that air conditioning did not work for the space-suited astronaut when he operated outside the Gemini Space Vehicle.  Being exposed to hot, directed sunlight in space, the astronaut became overheated, sweated profusely, and his heart rate increased to an unacceptably high level.  Under these conditions, judgment was compromised and the safety of the astronaut and the mission were jeopardized.  In 1968, a NASA program at Ames Research Center developed a spacesuit undergarment for cooling astronauts.  The system circulated a fluid cooled by a heat exchanger and delivered by a battery-powered mini-pump, through a network of tubes in the garment.  The system provided thermal management to the astronaut and allowed him to work in a microclimate environment similar to what he was normally accustomed.

This unique technology has been tested in a wide array of challenging environments and has received the honor of being inducted into NASA's Space Technology Hall of Fame.

As a technology leader, our Research and Development facilities located in Santa Clara, CA is constantly striving to improve our current products and develop new products.  LET has utilized our patented technology to develop several R&D projects for the government.  By combining technology and customers' feedback, we are able to turn special cooling challenges into dynamic products for the consumer.
