Heavy fuel oil (Furnace oil) needs preheating from room temperature up to about 100°C in order to reduce its viscosity from 1500 sec to 100 sec Redwood no.1 at 38°C. A constant working pressure of 1 to 3 kg/cm2 is developed for proper firing in fuel oil burners and also to achieve complete combustion in the furnace. Our heating and pumping units (HPUs) are conceived and designed for high thermal efficiency and minimum maintenance cost.

In addition to HPUs, Pumping and Filtering Units (PFUs) are also available without the presence of oil preheaters. These are suitable for firing High Speed Diesel (HSD) or Light Diesel Oil (LDO).
