[COLOR=#708090]Danfoss expands heat exchanger range
30 May 2007
The acquisition of a Chinese manufacturer means Danfoss now has one of the most comprehensive ranges of brazed plate heat exchangers to offer the compressed air industry.
‘A truly versatile product‘
Brazed plate heat exchangers are rapidly replacing the traditional shell and tube design as the industry‘s favoured product in air and gas compressors for:
• Oil coolers
• After coolers
• Heat recovery systems
• Air reheaters on mobile compressors
• Refrigerant dryers
With the acquisition of Qinbao, Danfoss can now supply its refrigeration and compressed air customers with brazed plate heat exchangers. “The flexibility of production at Danfoss Qinbao, and the versatility of the product, means that we can supply a tailored exchanger for any fluid flow and heat capacity”, explains Simon Firth, Danfoss Application Manager, Air and Gas Systems.
Brazed plate heat exchangers greatly outperform the traditional shell and tube design. Heat transfer performance is significantly improved with closer approach temperatures, while the amount of fluid required for heat dissipation is substantially reduced. The corrugated shape of the plates, coupled with a polished stainless steel construction, ensures low pressure drop of the air while still delivering a low fouling rate. And thanks to the exchanger‘s compact design, the size and weight of the unit is reduced by more than 75 percent in comparison to shell and tube units.
“The production line at Danfoss Qinbao is absolutely first-rate. In fact, the efficiency we have achieved there, coupled with the growing demand for brazed plate heat exchangers has led to a decision to expand production at the site.” adds Simon.
With the addition of brazed plate heat exchangers, Danfoss now offers
a truly comprehensive product range for compressed air and gas systems. Our product range includes valves, pressure and temperature controls, variable speed drives and a full line of refrigeration products （including controls, compressors as well as the new heat exchangers）.[/COLOR]
