Air-x-changers' ongoing investment in high-technology
is our key to delivering engineered solutions to you . . .
. . . FAST!
A new $500,000 investment in a 40 foot Plasma Arc
Steel Plate Cutter speeds jobs through the shop by eliminating material
handling delays, cutting the greatest number of parts out of a single piece
of stock material, and producing computer-perfect parts every time.
The cutter's dual beds eliminate material handling delays by
allowing material to be staged on the second bed while the plasma arc is
cutting material on the first bed. The plasma arc cutter can be loaded
simultaneously with two 6' x 20' steel plates up to 1" thick.
All steel plate parts are designed and detailed on
a Pro/ENGINEER® CAD system
in the drafting/design department. Parts of the same
material are then nested by computer into material efficient patterns and
downloaded via our internal network directly to the plasma cutter for manufacturing.
The cutter has full DNC (Direct Numerical Control)
and CNC (Computer Numerical Control) capabilities. The
plasma cutter maintains a tolerance on all cuts of twenty thousandths of
an inch (0.020") over a twenty foot span.
Hydraulic brake bending is used to enhance the speed of the manufacturing
process and to increase the integrity of the structural
portions of coolers by bending steel plate rather than cutting, welding
and/or bolting.
The new 350-ton, six-axis, CNC hydraulic brake with a twenty foot bed ensures
highly accurate bends of any angle of the structural panels. The brake's
multiple dies are used to curve steel plate to control and direct air flow
for optimum cooling efficiency.
A shotblasting process contributes to high quality welds by removing
any rust and mill scale from header plates prior to welding.
Adhesion of surface coatings is superior and lasts
much longer because of the shotblaster's resulting surface preparation.
The shotblasting process speeds up welding by eliminating the need for
most surface preparation by the welder.

All production tooling is maintained |

| Maximum production speed is maintained at each work center by using "Eversharp" tools from an in-house facility. The Machine Shop and Tool Center eliminates production downtime due to sharpening tools and eliminates waiting for refurbished tools from an outside vendor. |

A job never needs to wait for an outside third-party
inspector or to be "sent-out" because of our investment in staffing
and certification for non-destructive material testing. All
welds are immediately X-ray tested by full-time, in-house, certified technicians
and inspectors. air-x-changers has full-time ASNT-TC-1A Level 3 personnel to perform all radiography, ultrasound, and magnetic particle testing. There are ten full-time ASNT-TC-1A Level 2 certified X-ray film inspectors and thirty full-time ASNT-TC-1A Level 2 liquid penetrant inspectors in-house. |
Full-time, on-site Authorized Inspectors keep jobs moving without any
delay due to waiting for an outside inspector to arrive.
All welded assemblies are inspected for compliance with ASME, TEMA,
API, and individual customer specifications.
air-x-changers is the only manufacturer in the industry with separate in-house painting
facilities.
With over 30,000 cubic feet of capacity, the two paint booths easily handle
the largest size units.
Our ongoing investment in high-technology,
automation, staffing, certification, and common sense
add up to one thing:
air-x-changers offers you
a custom-engineered solution . . .
