Delphi Corp. has signed an agreement with Idalex Technologies of Arvada, Colorado, to be the world’s exclusive manufacturer of heat and mass exchangers (HMX) for cooling air using a recently discovered thermodynamic cycle called the Maisotsenko Cycle (M-Cycle). This is another example of Delphi expanding its activities beyond the automotive market.

The Coolerado Cooler, marketed by Idalex subsidiary Coolerado Corporation, is the first product introducing the HMX and the first product Delphi will supply with the technology. The cooler is used in a variety of applications and environments for residential, commercial and industrial facilities and was recognised in 2004 by R&D Magazine’s 100 Awards programme as one of the year’s most technologically significant products introduced to the world.


The HMX is the key component in the air conditioner that uses water as the medium for cooling. In addition, the air conditioner does not use a compressor or chemical refrigerants, and the only electricity required is for a fan to move air. The HMX works by saturating a working air stream with water that incrementally pulls heat away from both the product and working air streams through unique flow path geometries. The result is claimed “unprecedented” economical and energy efficient cooling.


Under the agreement, Delphi will manufacture the HMX product for Idalex and other customers to incorporate into their air conditioning products. Delphi expects to begin production for Coolerado in the third quarter of 2005 and, with Idalex, is exploring other market applications for HMX such as commercial, industrial and military applications.
