Introduction

Dry Gas Seal Operation, Maintenance, Installation and Commissioning

Course Objectives

The primary objective of this Dry Gas Seal System, Installation, Working Principle, Operation & Troubleshooting training course is to empower professionals with—

  • in-depth understanding and detailed information about dry gas seals, including their installation, commissioning, operation and maintenance
  • the required understanding of challenges and precautionary measures to be undertaken when working with dry gas seals, thus preventing hazards and losses to the organisation
  • adequate experience and knowledge to train other professionals on effectively working with dry gas seals
  • an enhanced perspective and eye for detail to audit existing equipment and machinery and identify the need for maintenance and/or repair of dry gas seals
  • the ability to contribute to organisational growth through reduced maintenance and repair costs
  • the required understanding of international standards and benchmarks of safety and operations to ensure that the seals are used as intended
  • an enhanced skill set and capabilities to work with dry gas seals in any industry, thus not feeling restricted to one industry alone

Who Should Attend?

  • Senior members of an organisation responsible for taking all critical decisions regarding expenses on machinery and other equipment
  • Engineers and other professionals working with dry gas seals
  • Managers and leads overseeing end-to-end operation involving dry gas seals
  • Compliance officers responsible for ensuring that all equipment and practices adhere to the required standards
  • Suppliers and vendors of dry gas seals who need to understand utility in an industrial setting
  • Any other professional who would like to know more about dry gas seals
