CYLINDERS & VALVE
The PYRO-CHEM KITCHEN KNIgHT II System has available
four different size cylinders: Models PCL-160 (Part No. 553163),
PCL-300 (Part No. 551194), PCL-460 (Part No. 551193), and
PCL-600 (Part No. 551196). Cylinder sizes are expressed in
terms of extinguishing agent capacity (i.e., the PCL-300 uses
3.0 gallons (11.4 L) of extinguishing agent). The cylinder is
manufactured, tested, and meets DOT requirements. Cylinders
come pre-filled with extinguishing agent and are charged with
dry nitrogen to a pressure of 225 psig @ 70° F (15.5 bar @
21 °C). Cylinder and valve assembly dimensions are shown in
Figure 2-1.
