AL-KO
Heat exchangers for warming fluids with process air are constructed
based on the specific requirements of terotechnology. Thier precise
design and concious choice of materials guarantee low energy consumption,
even at high blow-out temperatures. We remain flexible offering
short delivery times, even for custom-made units.

AL-KO
heat exchangers are supplied with a condensate escape feature for
operation with modulating gas burners.
All
heat exchangers can be supplied for operation with light crude oil,
kerosene or liquid gas.
Tubular
heat exchanger
AL-KO VDES and VDEL series flue gas heat exchangers are ideal for
installation in an existing housing. AL-KO tubular heat exchangers
work with the 4-vent-system, which means that exhaust temperatures
can be kept extremely low.
Type
S
Generates
blow-out temperatures of up to 300 °C at a maximum delta T of
50 K.
TYPE
HT
This
heat exchanger consists of heat-proof steel for blow-out temperatures
of up to 500°C.
Type
KB
This
heat exchanger made of heat and corrosion-proof material is especially
designed for use in areas with condensation or aggressive substances
are used.

Heat
exchanger, incl. housing
Heat
exchangers with a housing are manuafactured with isolation thicknesses
of 30 to 400 mm and a seal-welded inner housing.
Different
isolating thickness are used depending on the blow out temperature.
Based on the respective type of application heat exchangers are
used in the models s, HT or KB.

Heat
exchangers for warming fluids
The
VDE/W special heat exchangers for quickly heating up fluids are
ideal for installation in a horizontal position in liquid storage
tanks. They are designed for use with oil or gas burners.
Heat
is transferred effectively thanks to the dual vent system component's
surface area which is ribbed on the inside.
There
are eleven models available as standard with heat outputs of 50
to 520 kW.
Heat
exchangers for indirect heating with clean gas/hot air
Exhaust
air with high temperature levels eminates from many sub processes.
This
energy-rich exhaust air can often be redirected back into the overall
process.
AL-KO clean gas heat exchangers are individually designed and constructed
depending on the project-based installation situation.
Heat
exchangers with front panel
Al-KO
heat exchangers with adapted front panels for installation in an
existing housing and channels always guarantee easy assembly and
great service.

thicknesses :
100,
150 , 200, 300 mm and other thicknesses upon request

- 1.160 kW divided into 12 outputs levels
Naturally,
a whole host of basic material combinations from the VDES/L series
are available also for heat exchangers with front panels.
