Special Heat Exchanger Designs for Process Heating

Special applications requires special designed heat exchangers.

Not all tasks can eventually be solved by low-price plate-type or standard shell & tube heat exchangers.

Corrosive environment, fouling, extreme temperatures, pressures, complex compositions (compounds) and other proporties of the fluids makes the heat exchanger design very special.

Many manufactures are able to produce a heat exchanger, but only few are able to calculate the size, strength and adapt it to the actual demanding circumstances.

Practically all heat exchanger tasks can be solved, but it sometime takes a good cooperation between the designer and the user of the heat exchanger to make the right solution.

Most PROCESS AIR heat exchangers can be calculated and offered quite fast, but other special and customised heat exchangers are often extremely time consuming to calculate, optimize and for determine the preliminary design. For those heat exchangers the design work are done on consultant basis. This leads to a complete optimised solution with heat balance, thermo-physical design and estimated price.
The customer are of course free to decide whether to use AB&CO as supplier or as supervisor, - or to use another supplier, maybe even use customer's own engineers and own workshop.

AB&CO can assist any way it might be required, including providing manufacturing details.

The BELOW EXAMPLES with photos and text gives you an impression of the many type of heat exchangers that we have made since 1988.

Heat Exchangers


Process Air Heat Exchangers are used in applications where you never compromise. Industrial drying processes require high performances on compact units, by means of high temperatures and pressures. This require supreme reliability and low operation costs.

Heat sources are steam, thermal fluid, pressurised hot water, electricity and combinations of these.

Always attractive features when using AB&CO process air heat exchangers.
