All explosion protected engines today will typically have one of three types of control system. Our latest white paper (guide) by Lewis Cleary explains the differences and shows what is possible when specifying a diesel engine to power your well service equipment in hazardous areas.
While most pre-built ATEX engines (i.e Pyroban HazPaks) and Pyroban kits have some form of control system as part of the standard scope, most customers chose to upgrade the control system to suit specific project requirements.
To determine what’s needed, engine size, type and the application are the key considerations.
The new guide looks at the three main engine control options for engine packagers:
- Mechanical hydraulic / pneumatically actuated
- Passive – with multi inputs
- Active – with multi inputs
