Additional entry points provide for operators’ gloves. A service
panel incorporates access ports for welding torches, electrical
leads and cooling water supplies.
A purge gas entry port and an exhaust valve to vent displaced
gas to atmosphere are incorporated into each enclosure.
In the unlikely event that a repair is necessary, it can be carried
out by the user on-site. A kit is provided with each enclosure
for this eventuality.
Cost
Size for size, the HFT® range costs less than ten per cent of a
metal glove box and only two per cent that of a vacuum system.
Flexibility
Size and shape can be made to meet customer requirements.
Standard models from 0.3 to 3m3 are available from stock.
Weight is very low and the enclosures occupy little space –
the collapsed volume of a 1.25m-diameter system is less than
0.2m3 and it weighs only 8kg. They can thus be moved easily
and stored efficiently, so floor footprint is minimised.
Large viewing area
The entire upper section is manufactured from optically
transparent ultraviolet stabilised engineering polymer. This
offers the opportunity for use by several operators at the same
time – ideal for training purposes.
Multiple access points
Systems can be manufactured with numerous access loca-
tions for personnel gloves and gas/electrical entries. Large
leak-tight zips afford easy access for components.
Flexible Welding Enclosures® are now used by leading
manufacturing companies across the globe.
The aerospace, automotive, biochemical, medical, food
and beverage, semiconductor and nuclear sectors all take
advantage of the low cost and ease of use.
All these operations are exposed to some extent to the need
for extreme levels of quality control over cleanliness during
manufacture.
Contamination introduced during fabrication can so easily
lead to loss of strength and corrosion resistance. Particulate
contamination raises issues of expensive litigation or at best
rejection of product.
All standard enclosures are packed in a box 1,160 x 670 x
280mm, irrespective of size, and their shipping weights are
typically:
• 7.2kg for a 36" (900mm) diameter enclosure
• 8.7kg for a 48" (1,200mm) model
• 10.7kg for a 60" (1,500mm) size
