Replace TCE and Use Your Existing NESHAP Compliant TCE Degreaser

Our nPB-based solvents are very similar in physical characteristics to TCE, which makes it easy to switch-over from TCE to nPB in your vapor degreaser. Heat inputs, cooling capacity and operating features seldom need adjustment. Safety limit controls will need adjustment of the temperature set-points. Our expertise as the manufacturer of the ULTRA™ brand of vapor degreasers and having supported the switch-over from TCE to our nPB solvents on many, many occasions makes Reliance a valuable partner in successfully accomplishing the switch, while supporting your continued ability to vapor degrease. This can be done while successfully achieving your cleaning objectives consistent with the cleaning performance of TCE.
