WEST COLUMBIA,KryoTech Inc., a developer of refrigeration technology for thermal conditioning and control of electronic systems, has raised up to $5 million in its fourth round of venture capital from Delta Design.

KryoTech was founded in 1996 by executives and engineers from NCR Corp.

Delta Design is a supplier of test handling technology for the semiconductor industry. It is a subsidiary of Cohu Inc. (Nasdaq: COHU) in Poway, CA, near San Diego.

The company plans to integrate KryoTech thermal systems into its test handlers and has signed for an exclusive development and distribution agreement to jointly develop and sell certain products.

“KryoTech is pleased to work in partnership with Delta Design — in the development of next generation IC (integrated circuit) test handling equipment,” Allan M. Quick, chairman and chief executive officer of KryoTech, said in a statement. “The methods and technology traditionally used for IC test are reaching the upper limits of their capability. We believe the combination of KryoTech’s AccuKool thermal management and control technology with Delta’s test handler technology will set a new standard for the test handler industry.”

Delta Design’s parent company Cohu is also a supplier of closed circuit television, metal detection and microwave communications equipment.

“This agreement is intended to enable us to integrate existing KryoTech thermal systems into Delta Design’s test handlers and combine proprietary technologies from our two companies to co-develop advanced thermal control systems for exclusive use by Delta,” added James A. Donahue, president and CEO of Cohu. “We believe that this arrangement will enhance our ability to provide customers with high-performance, cost-effective solutions for temperature testing of ICs.”
