The heavy oil unit is used to heat oil and pump it to a set location at the desired temperature and pressure.
In most cases, the unit consists of two pumps, filters, resistors and various instrumentation. The parallel installation of pumps ensures uninterrupted operation and effective maintenance. The filters prevent impurities from entering the combustion process. The instrumentation is used to control the pressure, flow and temperature of the heavy oil. Typical instrumentation includes safety and control valves as well as temperature, pressure and mass flow gauges.
