The Dinh Company, Inc. located in Alachua, Florida was founded in 1983 to develop the use of Heat Pipes to increase dehumidification and to enhance energy recovery. Under a technology transfer contract with the NASA Kennedy Space Center, the Dinh Company research group has perfected and adapted a revolutionary heat pipe design to double the dehumidification capacity of an air conditioning system, providing cool, dry air at a fraction of the normal energy use. In 1991 two companies were spinned off to maximize the potential of such an invention and to exploit the new technology. 

Heat Pipe Technology, Inc. (HPT) was founded to apply heat pipes in HVAC. HPT has rapidly developed into a multimillion dollar company and has succeeded in promoting the Dinh Dehumidification Heat Pipes worldwide with 16 patents and prestigious licensees such as Mitsubishi in Japan, Teco in Taiwan, and GE in the United States. A full line of commercial and residential products incorporating heat pipes is now available from HPT, including the Dinh air handling units from 1,000 to 20,000 CFM, the Ultra-Efficient (BKPs) packaged dehumidifiers removing water from 100 to 1,300 lbs/day, Retrofit Add-On Dehumidifier heat pipes (DHPs) up to 200 tons, and Heat Recovery Units (HRMs) up to 50,000 CFM.

Advanced Dryer Systems, Inc. (ADS) manufactures Dehumidifier Heat Pumps as well as Closed Loop Dryers for agricultural, commercial and industrial drying. It has concentrated on developing more effective dryer systems based on the concept of dehumidifying the air prior to heating the air used in drying, in conjunction with heat recovery to increase efficiency. With US patent 5,343,632 and several other international patents, ADS is now commercializing a full line of standard dryers and custom designed and built drying systems.  

The newly patented Daika Rice Dryer has been tested and certified to save half the energy and to improve the yield of whole rice by reducing breakage (low temperature drying), greatly improving post harvest yields and help the world conserve its previous food stock.
