Alfa Laval Plate Heat Exchangers
|
  |
The plate heat exchanger consists of a plate pack of
corrugated metal plates with portholes for the passage of two fluids
between which heat transfer takes place. The plate pack is assembled
between a frame plate and a pressure plate and compressed by
tightening bolts. The heat transfer plates are fitted with gaskets,
which seals the channel and directs the fluids into alternate
channels. The number and size of the plates are determined by the flow
rate, physical properties of the fluids, pressure drop and temperature
program. The plate corrugation promotes fluid turbulence and supports
the plate against differential pressure. |
|
Plate heat exchangers features:
 | heat transfer efficiency up to five times that of other types of
heat exchanger
| compact dimensions which fit in a small space and are low weight
| low investment and operating costs
| flexible construction which can be extended or rearranged to
meet new process conditions
| low fouling as a result of turbulence created by the plate
pattern
| easy access to heat transfer surface for inspection, service or
maintenance
Alfa Laval is authorized to supply plate heat exchangers in
accordance with ASME (with or without U-stamp or N-stamp), BS5500,
AD-Merkblätter, Swedish Pressure Vessel Code and the European
Pressure Equipment Directive. Alfa Laval also holds ISO 9001
approval for the marketing, design, manufacturing and service of
heat exchangers. |

Typical applications for the plate heat exchanger:
During the more than 70 years the plate heat exchanger has been in
use, it has been winning ground for an increasingly broadening number
of applications. Over the years, the construction has proved so
advantageous that it has evolved into product developments described
under Types.
Today, the plate heat exchanger is universally used for efficient
heating, cooling, heat recovery, condensation and evaporation in a
multitude of applications in:
| Process Industry such as
- Hydrocarbon processing
- Petroleum and refineries
- Plastics
- End-consumer products
- Steel and metal production
- Mining
- Inorganic acid production
- Sugar mills
- Pulp & paper
| Energy production such as:
- Power generation, nuclear and non-nuclear
- Diesel power generation
| Marine industry
| Food industry such as:
- Dairy

Shell & Tube Heat
Exchangers
for General Applications
Alstrom Shell & Tube Heat Exchangers are
used in the HVAC, chemical, power, and food industries to provide
efficient heat transfer between hot and cold fluids. The customer
can select the tubing material and the sizes and locations of
connections for easy installation and piping, and can choose from
four head constructions:
| Bonnet head type “A” is the most
economical. |
| Head type “B” permits removal of the tube
bundle from the shell without dismounting the head piping. |
| Head type “D” provides a more economical
solution for this problem but is restricted to small nozzle
diameters. |
| Channel head “C” permits the checking and
plugging of leaking tubes without dismounting the head.
