Choose the option below that best describes your needs:

 

For standard duties

Industrial gasketed plate heat exchanger's versatility allows it to be designed and configured for applications ranging from relatively simple duties with low requirements to very demanding duties with the highest requirements on both performance and documentation. The models are used for heating, cooling, heat recovery, condensation, and evaporation. However, if you're working with an HVAC application, you'll likely want to choose an AHRI certified plate heat exchanger.

Typical applications:

  • Refrigeration
  • Engine cooling
  • Dairy and food
  • Chemical processing
  • Oil production
  • Power generation
  • ...and more

AHRI certified for HVAC applications

The AlfaQ range is similar to the Industrial range, except they're certified according to the AHRI Liquid to Liquid Heat Exchangers (LLHE) Certification Program which ensures thermal performance according to manufacturers’ published specifications in the HVAC market.  

Typical HVAC applications:

  • District cooling
  • Ice storage systems
  • Data center cooling
  • Free cooling

For refrigeration with aggressive media

Use Semi-welded gasketed plate heat exchangers as evaporators and condensers for refrigerations systems, when gaskets are not suitable for one of the process media. Semi-welded heat exchangers alternate welded channels and traditional gasketed channels and can also take a higher design pressure compared to fully gasketed plate heat exchangers. 

Typical applications:

  • Dairy, brewery and vineyard production
  • Marine
  • Fishing vessels and fish processing
  • Slaughterhouses
  • Chemical and pharmaceutical industries
  • Ice manufacturing, ice-skating rinks
  • Cold and frozen storage
  • Food retail outlets

When you have fluids with particles

WideGap gasketed plate heat exchangers are designed for fibrous fluids and for fluids containing coarse particles. The wide gaps between plates allow fibers and particles to easily pass through the heat exchanger with minimal clogging.

Typical applications:

  • Sugar
  • Bioethanol
  • Pulp and paper
  • Petrochemicals
  • Condensers for heat recovery

Evaporators - when concentration and viscosity of media are high

AlfaVap semi-welded heat exchangers are rising film plate evaporators and are suitable when concentration and viscosity of media are high.

AlfaVap’s advantage is they work also when the temperature differential between the hot and cold fluids approaches as low as 4.5°F meaning that lower grade steam and more effects in series can be use in an evaporation system compared to the shell-and-tube systems.

Typical applications:

  • Sugar refinery evaporation systems
  • Sweeteners evaporation systems
  • Bioethanol and caustic evaporation
  • Thermosiphon reboiler

Condensing of vapor under vacuum

AlfaCond plate condensers are specifically designed for condensing of vapor under vacuum. They're an alternative to direct condensers when condensate recovery is the goal and when there are space constraints. Non-condensables are removed from the condensate outlet pipe and led to the vacuum system.  

Typical applications:

  • Evaporation systems
  • Ethanol condensers in bioethanol plants
  • Pan vapor condensers in sugar refineries
  • Turbine condensers in small power plants

For highly corrosive media

Diabon plate-and-frame heat exchangers are used for highly corrosive media, combining high-efficiency heat transfer benefits with the exceptional corrosion resistance of graphite material.

Diabon is a dense, synthetic resin-impregnated high quality graphite with a fine and evenly distributed pore structure, and can be used with corrosive media up to 390°F.

Ideal for handling highly corrosive fluids such as:

  • Hydrochloric acid and gas in all concentrations
  • Sulphuric acid up to 90%
  • Hydrofluoric acid up to 60%
  • All concentrations of phosphoric acid
  • Pickling acids in surface treatment plants
  • Electrolytes used in the mining industry
  • Mixed acids
  • chlorinated hydrocarbons
  • catalysts such as aluminium chloride
