Retractable Chemical Injection Quills
Retractable Chemical Injection Quills allow the quill to be removed from service without depressurising and draining the process main. Use these where the system valving or process does not easily allow for shut down of the process main.
General purpose injection quills with a 1000 kPa rating.

Where there are larger sizes, higher pressures, higher velocity and more turbulance, the heavy service range is better suited.

Non-Retractable Chemical Injection Quills
Non-Retractable (or Fixed type) Chemical Injection Quills are the simplest method of getting chemical into the main flow stream, but to maintain or service the system, the process line must be depressurised and drained. Use these on small systems where the process main can easily and economically isolated for maintenance.
Open Channel (OC Units) are designed for immersion in a channel to distrubute chemical.
These are the simplest range and design of injection quills.

Sample Probes
Sample probes take a water sample from the mid section of a pipeline. This means a truely representative sample is taken rather than from the inside surface of the pipe.
Our sample probes are available as either retractable or non retractable designs.
The representative process sample is drawn from the mid section of the process pipe through the bevelled tip of the probe. The isolation on the end of the probe allows for either use of the probe for simple jar sampling or for connection to a sample line running to an analyser.

Accessories
H2O Rx supplies accessories to assist in making your injection quill simple to install and maintain.
Accessories include:
| Chemical Inlet Valve Assembly | Made to ensure that chemical lines can be effectively isolated, and the quill checked and maintained without damaging installation pipework. Especially useful for large injection quills. | Brochure |
| Flexible Hose Assembly | For smaller quills a simple hose connection will allow the quill to be retracted. | Brochure |
| Security Enclosure | Security enclosures can help ensure that injection quills are not interfered with. | Brochure |
| Secondary Containment Box | Secondary containment around the injection quill is sometimes required. H2O Rx an provide a cusomised solution to provide secondary containment and still allow the quill to be maintained. | Brochure |
