Zero-Discharge TRU TEMP Black Oxide Finishing System

The30-min TRU TEMP low temp black oxide process is now available in a newZero-Discharge configuration that eliminates the need for a drain connection.

ThisTRU TEMP system from Birchwood Casey utilizes Ion Exchange technology to purifyand recycle the rinse waters, resulting in a "closed-loop" zero-dischargeinstallation. The technology is available for all size systems, including40-gal, 100-gal and larger capacity custom tank systems.

Theprimary benefit of the Ion Exchange equipped TRU TEMP system is that theprocess tanks can be physically disconnected from the drain. The Ion Exchangesystem removes all particulates and dissolved ions from the rinse waters,generating de-ionized water that is re-used over and over. The user gets ultraclean rinse tanks, no discharge to the drain and near zero water consumption.

TheTRU TEMP process is can be an in-house substitute for dangerous 290F hot oxideprocess. Operating at 200F, the TRU TEMP system avoids thesevere hazards of a boiling tank and is safe to install in any area of theplant. Now with the Ion Exchange feature, a TRU TEMP installation can be usedin any location without sewer district restriction.

With30 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 processstreamlines part movement, provides better control of finished part inventoryand enhances ISO accountability. It also gives the user a "same-day turnaround"capability without raising finished inventory levels.

SatisfyingMil Spec DTL 13924D and AMS 2485, the TRU TEMP process containsno 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-dischargefrom the system, the Ion Exchange option will satisfy those needs.

The TRU TEMP 100-gal line is supplied as acompletely pre-engineered process line for fast setup. The system utilizesseven individual tanks, each measuring 24 x 40 x 28 inches deep, with a 100-galcapacity. The complete process line, with Ion Exchange, occupies about 120 sq ftof floor space and can process up to 4,000 lb of work per shift.
