We are pleased to announce the maximum spacing limit for the Accelerator with the Navy Up-Top Plate has been increased. When operating with a 10 (0.7 bar) or 15 (1 bar) psi Pressure Regulator, spacings of up to 21’ (6.4 m) are allowed with nozzle sizes #10-#39. Selecting the already economical Up-Top Accelerator at wider spacing requires fewer sprinklers making it an excellent choice in competitive situations as a low cost sprinkler package. When using a 6 psi (0.4 bar) Pressure Regulator and when higher uniformity is required, a maximum spacing of 11’ (3.4 m) is recommended. Please contact us if you have any questions.
