Puroflow Filters To Protect

Sperry Computers —Literature Available

Puroflow Marine Corporation, which recently announced the de- velopment of a new series of com- pact power-line filters for OEM ap- plications, has reached agreement with Sperry Corporation to provide

Puroflow filters for Sperry's new line of "ruggedized" on-board com- puters for the marine industry.

The Puroflow filters will provide essential protection for the Sperry computer from the harmful effects of voltage surges and conducted electromagnetic interference (EMI).

Sperry has developed a special version of its popular PC for use abroad ships and offshore rigs, and as an enhancement to its satellite communicators. The computer has been extensively ruggedized with vi- bration and shock isolation and power-line conditioning to permit dependable operation in the harsh marine environment. The Puroflow filters were selected after an exten- sive evaluation in which they were found to offer an extremely cost- effective solution to the problem of power-line fluctuations, according to Sperry vice president, marketing,

C.R. Kenney.

New Technology for High Performance

Compact Heat Exchangers

SPHERE MATRIX 'SPHERE MATRIX a

The heart of the SPHERE MATRIX

Technology consists of nesting the tubes in a regular matrix of solid spheres around the outside and utilizes fluted spheres, properly spaced, on the inside The spheres interrupt the boundary layer growth and thereby enhance the heat transfer performance.

Fluted sphere inserts or solid sphere bundles can be used separately depending on the needs of the application

Puroflow's small modular OEM power-line filters were developed to meet the perceived demand for ade- quate built-in protection in modern electronics systems, said Puroflow vice president G. Howard War- ren. Voltage fluctuations and EMI are common problems aboard ships and offshore oil rigs, causing fre- quent breakdowns and malfunc- tions in the sophisticated electronic suites now used in modern marine management. The Puroflow devices have been extensively tested and independently documented to pro- vide total protection, even from the most severe voltage surges, said Mr.

Warren.
