5.2 Maintenance (Continued)
Thrush Co. offers an optional Double Wall configuration for leak detection. This option
utilizes tubes with an additional tube inside each of them. If the outer tube becomes
punctured for any reason, the inner tube maintains the separation of steam and process
water. The space between the inner and outer tubes will then start to fill with water and
leak out of the Leak Detection Grooves at the bottom of the unit (Figure 5-1). If water is
detected in this area, the tube bundle must be replaced. Contact your representative for
replacement tube bundles.

Never try to re-use old gaskets.
