Brazed heat exchangers

 

Compact brazed heat exchangers Swep – are the most effective and productive equipment engaged in heat transfer process up today. 
 

Main advantages:

  •  Extreme compactness;
  •  Maximal productivity of material usage;
  •  Minimal internal volumes;
  •  High operating pressure;
  •  Maximal rigidity;
  •  Self-cleaning of operating surfaces.

 

It is not the full list of all the advantages of compact brazed heat exchangers Swep.

Modular components, combined in different ways, provide possibility to meet any customer’s needs. 

 

  • паяные теплообменники  Flow: up to 640 m³/hour.
  •  Operating pressure: up to 40 bar.
  •  Temperature: -195°С – +350°С.
  •  Connections: DN15 – DN200 Welding flanges, thread. 

Compact brazed heat exchanger Swep consists of corrugated plates package with closing plates sets in front and behind. Closing plates set includes sealing plates, sealing rings and cover plates. Different types of connection are used to connect Swep to customer’s system. Brazed joint is formed in every point of contact between main material and braze alloy during vacuum brazing. Plates structure creates two separate channels or circuits in heat exchanger.
Standard place of connection openings is the front side of Swep heat exchanger. Connection type can be customized in accordance with specific requirements of local market and definite application. Closing plates are used for leak proof separation of space between cover plate and one of corrugated end plates forming channels. Closing plates can be named first plate and end plate. Closing plates are integrated with cover plates in some Swep models. Quantity of cover plates depends on heat exchanger model, pressure range, etc. Some Swep heat exchangers have sealing rings for space separation between channel-forming plate and cover plate, others have such a structure that sealing rings are integrated with cover plate and first/last channel-forming plate. There is a standard configuration of plates set on the picture above, but other variants are possible as well. It is to note that herringbone direction changes from plate to plate.

  •  Plates material – AISI 316, Mo-steel.
  •  Temperature from 195 up to + 350 °С.
  •  Power up to 250 kW.

Braze alloy types:

 

  •  Copper (99,9%);
  •  Nickel alloys.

  

Plates design:

  

  •  Symmetric angles of relief incline at an obtuse and acute angles;
  •  Double plates for processes, where operating mediums mixture is not allowable.

Компактные паяные теплообменники

Compact brazed heat exchangers were developed in the end of 70s by a group of engineers, who founded SWEP company afterwards.
Today SWEP is a world leader in SWEP technology and suggests full range of heat exchangers meeting your requirements accurate.
 


 

New heat exchangers from stainless steel 

 

ТЕПЛООБМЕННИКИ ИЗ НЕРЖАВЕЮЩЕЙ СТАЛИSWEP company commissioned a new manufacture line of fully stainless compact heat exchangers for work with different mediums. SWEP company introduced a new production range of fully stainless heat exchangers on IKK exhibition. It was a result of many years work carried out by metallurgists, manufacturers and SWEP specialists in the field of heat-transfer.
A new production range of heat exchangers provides unique possibilities for compact heat exchangers usage in various mediums that require absolutely stainless materials.
