AlfaRex

Welded Plate Heat Exchangers
AlfaRex welded plate heat exchangers are free of gaskets. It is well suited for high temperature and high pressure applications with clean media. Media can be very corrosive acids since no gaskets are used.

Applications:

  • Refrigeration
  • Batch Reactors
  • Gas dehydration plants
  • Solvent recovery processes

AlfaRex design

The AlfaRex consists of a batch of metal plates that are corrugated and are welded together. Openings allow the passage of two different fluids between alternate plates through which heat transfer takes place. The plate pack is installed in a metal frame with tightening bolts. The plate corrugations are designed to achieve high thermal efficiency.

Compabloc Heat Exchanger

Compabloc Heat Exchanger
The Compabloc Heat Exchanger is a welded plate heat exchanger with no gaskets between the plates. The plates are welded alternatively to form channels. Ideal for chemically aggressive environments and high temperatures.

Models: CP15,CP20, CP30, CP40, CP50, CP75 and CP120 with heat transfer areas ranging from 0.7 to 840m2 (7 to 8985 ft2) per unit.

Weld Technology

Compabloc consists of a stack of corrugated heat transfer plates in stainless steel or exotic materials, welded alternately to form channels.

Plate pattern

The laser-welded range of Compablocs is available with three plate patterns – the K series, designed for efficient mechanical cleaning, the L series for high-pressure applications, and the X pattern combining high pressure and mechanical cleaning ability.
Flow paths

The two media flow in alternately welded channels between the corrugated plates.

Body

The Compabloc frame consists of four corner girders, top and bottom heads and four side panels with nozzle connections. These components are bolted together and can be quickly taken apart for inspection, service or cleaning.

Wide selection of plate materials

Compabloc is available in virtually any material that can be pressed and welded, including:

  • AISI304L
  • alloy C22
  • AISI 316L
  • alloy C276
  • alloy B-2
  • titanium
  • tantalum
  • titanium palladium
  • incoloy 825
  • 254S MO
  • hastelloy C2000
  • 904L (UB6)

Spiral

Alfa Laval Spiral Heat Exchangers
Alfa Laval Spiral Heat Exchangers are essentially self cleaning and versatile in design.

Product ranges

Spirals come in fixed-size and customized product ranges to meet the needs of our customers.

Fixed-size range

We make fixed sized small units for general use, and for application-specific uses such as the wastewater industry.

Customized range

The majority of spiral heat exchangers are individually customized to customers specific needs.

Unique shape has unique properties.

A spiral heat exchanger has two spiral channels that are concentric, one for each fluid. The curved channels provide great heat transfer and flow conditions for a wide variety of fluids. The overall size of the unit is kept to a minimum. Installation space is optimized because of efficient size of unit.
