30-min TRU TEMP low temp black oxide process is now available in a new
Zero-Discharge configuration that eliminates the need for a drain connection.
TRU TEMP system from Birchwood Casey utilizes Ion Exchange technology to purify
and recycle the rinse waters, resulting in a "closed-loop" zero-discharge
installation. The technology is available for all size systems, including
40-gal, 100-gal and larger capacity custom tank systems.
primary benefit of the Ion Exchange equipped TRU TEMP system is that the
process tanks can be physically disconnected from the drain. The Ion Exchange
system removes all particulates and dissolved ions from the rinse waters,
generating de-ionized water that is re-used over and over. The user gets ultra
clean rinse tanks, no discharge to the drain and near zero water consumption.
TRU TEMP process is can be an in-house substitute for dangerous 290F hot oxide
process. Operating at 200F, the TRU TEMP system avoids the
severe hazards of a boiling tank and is safe to install in any area of the
plant. Now with the Ion Exchange feature, a TRU TEMP installation can be used
in any location without sewer district restriction.
30 min blackening time, TRU TEMP forms a durable, black magnetite finish of
.000020 inch thickness equal to that of hot black oxide. The in-house process
streamlines part movement, provides better control of finished part inventory
and enhances ISO accountability. It also gives the user a "same-day turnaround"
capability without raising finished inventory levels.
Mil Spec DTL 13924D and AMS 2485, the TRU TEMP process contains
no EPA regulated metals. When a city sewer connection is conveniently located,
the process rinse waters are normally sewerable as non-hazardous discharge,
without waste treatment. For those installations that require zero-discharge
from the system, the Ion Exchange option will satisfy those needs.
The TRU TEMP 100-gal line is supplied as a
completely pre-engineered process line for fast setup. The system utilizes
seven individual tanks, each measuring 24 x 40 x 28 inches deep, with a 100-gal
capacity. The complete process line, with Ion Exchange, occupies about 120 sq ft
of floor space and can process up to 4,000 lb of work per shift.
Siemens and Fraunhofer Institute for Laser Technology have achieved a faster production process based on selective laser melting for speeding up the prototyping of big, complex metal parts in gas turbine engines.
