Compabloc+ | Alfa Laval

The performance you expect – and so much more

With Alfa Laval Compabloc+, the efficient, cost-effective and reliable performance of the Compabloc family is now available for a wider range of demanding duties. The unique design, developed with the feedback and needs of our customers in mind, enables safe operation at pressure up to 60 bar. It’s the latest example of how we work closely with you to continuously find new ways of improving process sustainability.

When the pressure is on – choose a champion

  • Superior sustainability in a broad scope of demanding heavy process duties.
  • Ultimate reliability thanks to the market’s only design with a fully confined, graphite gasket.
  • A solution to bottlenecks, with increased heat recovery potential under high pressure conditions.
  • Optimized for minimum fouling with fully cleanable design to retain the original thermal performance.
  • Simple, cost-effective installation with the same compact footprint as equivalent Compabloc models.

Alfa Laval Compabloc has long been the market’s undisputed champion when it comes to delivering sustainable heat transfer performance. Compabloc+ takes all the proven advantages of the Compabloc design and combines them with all new innovations to support duties with even higher design pressures. The secret is Alfa Laval’s revolutionary sealing concept: +Seal. Unlike traditional flat gasket designs, +Seal introduces the first fully confined graphite gasket in a bloc-type heat exchanger. This prevents the risk of media leaks at pressures as high as 60 bar, while simultaneously simplifying maintenance by protecting against overtightening as well as creeping.

Hydrotreating and hydrodesulphurization

A growing number of refineries have turned to naphtha hydrodesulphurization units in order to meet changing sulphur regulations for motor fuels. Traditionally, shell-and-tube heat exchangers have been used to recover heat in this energy-intensive process.

Complete Compabloc range

Compabloc offers 3-5 times the thermal efficiency of traditional shell-and-tube solutions, with a more compact design that is much easier to install and service. Laser-welded construction offers superior reliability in duties with aggressive media and high pressures and temperatures.
