INTRODUCING THE ECOSSE PX-1 ...A HIGH PERFORMANCE, EXPENDABLE EBW/EFI FIRESET

The Ecosse PX-1 is a low cost, high performance expendable EBW/EFI fireset. As with most of the firesets on the market today, its circuit, a high voltage supply, and an output section. The safety circuit, of course, provides most of the protection. The high voltage supply takes the input voltage (205V @ 160mA), steps it up to 5kV, and charges the capacitor in the output section. The output section contains a spark-gap as an over voltage switch; when the voltage on the output capacitor reaches 5kV, the spark-gap breaks down and dumps the stored energy into the attached detonator.

The PX-1 has the highest temperature rating of any system on the market, with an operating range from – 25ºC to +225ºC. It can initiate EFI detonators through six inches of twisted-pair wires or 3 feet of coax cable; EBW detonators can be fired through 10ft and more of twisted-pair wires. Its compact dimensions (5” X 0.82” X 0.74) allow it to fit in virtually every gun system in use today, including pressure housings with an OD of 1-3/8”.

It has been fully certified by Orion International Technologies at Sandia National Laboratories to standards that exceed any practical level of threat that might exist in the oilfield environment, including stray DC voltages from -600VDC to +150VDC, AC voltages at 600V rms from 40Hz through 20kHz, RF testing from 260kHz at 50V/m, electrostatic discharges, and severe direct lightning strikes to the wireline within 3ft of the PX-1 itself. Particularly on offshore platforms, these safety features can result in very significant cost savings for the operator.
