                        RISK          High

                        DISCHARGE     Stormwater
                        UNIT SUPPLIED P006 - PuraceptorTM Class 1 with 20,000 litre retention tank
                        T.F.R.        6 LPS
                        OPERATION	Due to the remote position of this transformer and the impact on the
                                      environment in the event of a failure, it was essential to the power
                                      provider to have a proven and reliable system. SPEL PURACEPTORTM
                                      was selected due to its proven “track record” in supplying the power
                                      industry, overall reliability and the necessity to have optimum quality
                                      discharge. Whilst the design of 6 LPS from the bund area caters for
                                      the nominal flow, a 20,000L spill retention was built into the system
                                      to hold the capacity of a transformer rupture.

                        DISCHARGE           Stormwater to river
                        UNIT SUPPLIED       P040 - PuraceptorTM Class 1 - oil capacity 70,000 litre
                        T.F.R.              40 LPS
                        OPERATION	This unit was installed to treat stormwater and firewater from
                                   the deluge system simultaneously. The unit caters for a 40 LPS
                                   flow rate, and has the capacity to capture a 70,000L transformer
                                   spillage and remain operational. SPEL units are designed and
                                   built to BS EN 858.1. 2006 it was able to be used as a
                                   designated flame trap, further enhancing its selection for this site.
