In 2004 FBM Hudson Italiana took over ICOSS, incorporated in 1974 as manufacturer of fully welded plate heat exchanger and high-pressure vessels for chemical, pharmaceutical, petrochemical and aerospace industries.
All stainless-steel grades Duplex Nickel Zirconium
Hastelloy Aluminum Super alloy Titanium
The fully welded plate HE PLATEBOX is born from 20 years of FBM Icoss experience in the production of welded plates and high pressure vessels for the chemical field and aerospace industries.
High Quality Service Using Thin plates
LIMITS OF FBMICOSS FULLY WELDED PLATE HEAT EXCHANGER
Heat Exchange Surfaces employed:
Type “G” + PICTURE G
This heat transfer surface is fabricated by embossing two plates of same thickness by hydraulic or pneumatic pressure, welded with an automatic spot welding system. It is possible to use all materials, compatible with resistance welding.
Application: Industrial Refrigeration
Plate type “G” grants many advantages instead of the conventional pipes system:
In chillier storage facilities, is possible to obtain water temperature near to 0° C without freezing risk.
In ice banks system, ice volume accumulated is proportional to the exchanger surface; using conventional tubes system it is less interesting to accumulate high thick-ness of ice.
In the cryogenic gas evaporator, plates type “G” with suitable canalization, allows to maintain constant gas speed, also in the different evaporation steps.
It is possible to use type “G” plates in falling film refrigeration system, to produce ice flakes.
Type “GP” + PICTURE GP
Similar to“G” type, but using two plates with different thickness. The thicker plate remains flat after embossing.
Application: Food Industry
For this market FBM Icoss produces jacketed vessels parts (shell, formed head or flat bottoms) usually with type “GP”.
The production system, with fully automatic resistance spot welding machine, allows to use low thickness metal sheets with high pressure in the jacket (also for cryogenic gas, ammonia or steam) . The flat surfaces are ready to be used or could be polished to the requirements of the customer
Fabricated by welding a pre-deformed plate to a flat plate. The dimpled plate is pre-deformed with different shapes, to obtain an air space varying from 3 to 15 mm between the plates. The welding can be performed by MIG, TIG or Resistance Spot process. No limitation on the thickness plates used.
Application: Chemical Equipment
For pressure vessels, where wall thickness could be high, it is possible to use type “I” surfaces,
Similar to “I” type but using two pre-deformed plates. Different shapes are available, related to different requirements.
The heat transfer plate is flat on both sides. Type “TP” is obtained by welding two flat plates (sometimes with different thickness) to an intermediate inner wall, to obtain a constant internal space. The spacer designs an inside path for the cooling/heating media. The welding of three sheets is performed at the same time by resistance spot welding.
This type of heat exchanger, as type “G”, is manufactured by resistance, welding three sheets instead of two.After embossing two separate circuits are available.
The heart of the PLATEBOX production is our extremely powerful resistance spot weld machine (1250 Kw power) that allows easy welding of plates up to 6+6 mm with low thermal input.
This kind of weld guarantee a surface corrosion resistance equal to the raw material.
The sealing of each plate depending on the type, HP-LP, is done by resistance seam welding or by plasma welding.
At the end, the final assembly is done by means of a special machine where the plates are pressed together and welded at the same time to avoid any distortion.
Manifolds and minor parts are welded with conventional equipment by qualified welder.
The welding processes, sophisticated machinery and especially the Hastelloy, pure aluminium and zirconium.Carbon steel is not a conventional material but it could easily be used in case of special need (no cost saving).
