The CD15 Dispenser has become the industry standard for epoxy injection, injecting cracks in more than 25 countries. It has a reputation earned by consistently delivering precisely metered resin under difficult construction jobsite conditions. Regardless of the ratio, the difference in viscosity between components, the flow rate, the pressure or the experience of the operator, the CD15 Dispenser consistently delivers thoroughly catalyzed resin.
The CD15 is user friendly. The controls consist of a single on/off switch, a single pressure regulator and a pressure gauge. Once the dispense pressure is set, the system will maintain that pressure. This feature allows a single operator to inject numerous ports at the same time.
The injection of numerous simultaneously is standard procedure with the CD15 Dispenser. This technique of using a manifold improves the productivity immensely and is especially rewarding when injecting hairline cracks that require longer injection times. The injection of three to six ports at once is common practice.
Pneumatic operation and welded stainless steel construction allows the CD15 Dispenser to be used in almost any environment and withstand the the abuses of a construction jobsite.
The CD15 Dispenser is designed exclusively for the construction industry by those with more than 45 years' experience in construction. This background is important because dispensing demands in construction are unique and seldom met by systems designed primarily for industrial applications.
Items exposed to catalyzed resin are cleaned with a charged Gusto Purge Assembly. The Gusto tank fully charged with air will have sufficient energy within the tank to clean up at least the major components.
1. “Burp” the CD15. To do this, dispense a few ounces of resin material into a waste container immediately after removing the mixer from the dispenser. This will flush any base resin that may have entered the catalyst fitting or valve.
2. Immediately after burping the dispenser and disconnecting the mixer, cap the dispenser outlet fittings with the caps secured at the magnetic bracket. Secure the mixer to the manifold at the Gusto tank. Disconnect the air supply from the dispenser and connect it at the Gusto air inlet. Close the FF-2 valve, and then rotate the selector valve to point to the mixer.
3. Allow the pressure in the volume tank on the compressor to catch up before introducing the solvent bursts. With the maximum pressure and volume available, open the fluid outlet valve. Quickly shake the Gusto tank to splash small solvent bursts into the air stream. Space the bursts about 5 seconds apart. If a low viscosity resin is being used, 5 or 6 bursts are usually sufficient to clean the mixer and tubing. However, if a thick material must be purged, more bursts will be required. Keep the bursts as small as possible, for large dosages of solvent choke the air stream velocity, reducing the scouring effect. Continue until the exhausted solvent is free of resin.
4. To clean the interior of the FF-2 valves, lay the Gusto tank on its side so that solvent floods the outlet fitting. Then, quickly rotate the valves a few times under the full solvent flow.
