Hazardous Location Engines
Hazardous location engines are found in a range of environments and applications. In the oil and gas industry, these engines play a critical role in providing power for gas compression operations where downtime is simply not an option. Extreme cold can prevent engines from operating efficiently, slowing production and costing money. Heating and circulating the coolant, oil or both fluids while in standby mode ensures optimal temperature for operation is maintained, keeping the system ready to start with full-load power when needed.
