Zero-Discharge TRU TEMP Black Oxide Finishing System

The 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.

This 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.

The 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.

The 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.

With 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.

Satisfying 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.
