Heat exchanger, fired heater & process vessel fabricator
Fraser™ heat exchangers
Fraser's clients receive both their undivided attention and guarantee on performance and workmanship. Their heat exchanger designs are based on the most reliable and competitive design philosophies, from standard process heat exchangers to high technology feed-effluent exchangers for utility, petrochemical and refining plants.
Hairpin heat exchangers
Hairpin heat exchanger designs can increase heat transfer coefficients in single-pass process streams with high temperature differentials.
The single-pass design has tube-side and shell-side fluids running counter-current to each other, maximising the temperature difference between the two streams. This type of heat exchanger also offers a range of benefits to the mechanical and maintenance engineer, including:
- Independent tube sheets for high terminal temperature differences
- Thermal shock resistance
- Cycling
- Long radius U-bends for effective thermal expansion
- High temperature differences
- Ease of cleaning
- All-welding baffle cages for durability
- High pressure closures for pressures up to 10,000psi
- No internal bolting
Air-cooled heat exchangers
Fraser offers a range of different air-cooled heat exchanger configurations in order to meet the specific requirements of both the process and the site location.
Whatever the configuration, one of the most important design criteria is to ensure that air is allowed to freely enter and leave the system, ensuring maximum heat transfer. Fraser's design engineers are fully conversant with the different operating criteria of a range of process facilities and will recommend and provide the most appropriate solution.
