With over 50 years of experience in the design and manufacture of brazed aluminum heat exchangers (BAHX), Chart Energy & Chemicals is continually building upon the proven performance and best practices from its operation to raise world industry standards.
Chart E&C serves a global market through its US manufacturing facility in La Crosse, Wisconsin, the European sales and engineering office in Wolverhampton, England and a network of local sales offices located in key territories throughout the world.
Chart E&C's aluminum plate fin heat exchangers are designed for a variety of applications with maximum design pressures of up to 2300 psig. Chart Energy & Chemicals' heat exchangers are typically 20% the size of comparable performance carbon or stainless steel shell-and-tube exchangers. This technology leads to lower capital costs, lower installation costs and lower operating costs over a wide range of cryogenic and non-cryogenic applications.
The multiple stream capabilities of the Chart E&C heat exchanger simplifies multiple shell-and-tube limited stream configurations into a single, compact, brazed aluminum unit. This feature has a significant effect on installation and operating costs, minimizing engineering, insulation, support systems, testing, documentation, transportation and site arrangements.
BENEFITS OF CHART HEAT EXCHANGERS
Lower Operating Temperatures
Chart Energy & Chemicals' heat exchangers are well suited for the low temperature requirements of cryogenic applications since the 100% aluminum construction can withstand temperatures as low as -452°F (-269°C) and very high pressures (i.e. 1750 psig/120 bar g or higher).
 Lower Capital Costs
Chart E&C's brazed aluminum heat exchangers are compact and lightweight and provide 300 to 450 square feet of heat transfer surface per cubic foot of exchanger volume (1000 to 1500 square m / cubic m), which is six to ten times higher than that of a comparable shell-and-tube heat exchanger. This characteristic, coupled with the enhanced heat transfer performance of plate-fin construction, produces as much as twenty times greater heat transfer performance (UA) than shell-and-tube exchangers of equal size. This higher efficiency can correlate to a Chart E&C heat exchanger costing approximately 25-50% less and weighing 95% less than a stainless steel shell-and-tube exchanger.
Flexible Design
Chart Energy & Chemicals' heat exchangers can be designed with more than ten streams and a nearly unlimited number of configurations by varying parameters such as block size and shape, fin type, layer stacking arrangement and flow scheme. This multiple stream advantage is realized in the potential of combining numerous heat exchanger services into a single compact heat exchanger.
Lower Installation and Operating Costs
Chart E&C’s multi-stream design can result in significant cost reduction in:
- Engineering
- Insulation
- Support systems
- Installation
- Testing
- Documentation
- Transportation
- Plot plan requirements
 Additionally, Chart E&C's heat exchangers allow temperature approaches as low as 2°F (1°C) that result in lower compressor horsepower requirements and lower plant operating costs.
Chart Energy & Chemicals' Heat Transfer Fins
Chart E&C's design and engineering teams constantly challenge the variables in heat exchanger fin design, analysis and testing. Heat transfer fins are experimentally tested for both heat transfer and pressure drop performance and cover a wide range of characteristics. The company has developed improved heat transfer and fluid flow performance correlations for both single-phase and two-phase fluids.
