BTU International (Nasdaq: BTUI), a leading supplier of advanced thermal
processing equipment and processes to the alternative energy and electronics
assembly markets, today announced that it has received multiple orders for its
new Tritan metallization drying and firing system.

The orders come from a diverse group of customers including Asia-based high
volume manufacturers and a photovoltaics research institute. The orders are
expected to ship in the third and fourth quarter of this year.

"The customer response to our next generation metallization system has been very
positive, in part because some have achieved higher efficiencies than their
process of record," said Jan-Paul van Maaren, Ph.D., BTU International`s vice
president marketing. "We are looking forward to showcasing the system at the
EUPV show in Hamburg, Germany, between September 21st and 24th."

The Tritan drying and firing furnace features a proprietary multi-drive system
which enables aggressive temperature spikes without compromising the drying,
burnout and cooling process steps as single-drive systems do. With optimized
wavelengths and innovative heating and gas delivery technology, wafers being
processed in the Tritan system can be heated at a steep temperature gradient.

BTU offers solar processing equipment for both silicon and thin film
photovoltaics. In thin film photovoltaics, BTU`s equipment is used for both the
CIGS and the CdTe processes. Silicon photovoltaic applications are served by
BTU`s metallization systems and in-line diffusion systems.
