Glycol injection unit (GIU)
The GIU utilises an air operated double head dual acting pump (DHDA) to produce an extremely high pressure and infinitely variable liquid flow when required. Typical flows rates are given as 3.5 litres per minute (lpm) at 15000psi and 1.6lpm at 20000psi.
The DHDA pump has been designed to deliver an infinitely variable flow rate using standard rig air pressure, GIU equipment is easily integrated into RCP’s High pressure temperature monitoring equipment for automatic control of glycol injection required in emergency situations.
The DHDA pump offers a proven low maintenance, highly reliable solution for any critical injection process, with the ability to stall at a predetermined pressure and hold this fixed pressure without consuming power or generating heat. The pump is one of the most robust on the market.
This unit is suitable for installation in hazardous areas and is easily integrated with all other RCP control and automation equipment.
