Pyroban® recently delivered a HazPak 350 engine package fitted with PCS 2 Gas Control System for use in an onshore oil & gas application in South America with Zone 2 operations.

This project features an ATEX compliant HazPak 350 based on a Cat C9 diesel engine with Pyroban explosion protection.

Pyroban worked with the customer, to extend the base frame and integrate the HazPak to their specification. The PCS 2 system was also installed on the extended base frame panel stands which allows the customer to then package their centrifugal pump.

This overall solution is more cost-effective overall and streamlines logistics and build time.
