Ensuring Clean Fuel at Good Hope Hospital

Markets: Power Generation
Application: HospitalLocation: Sutton Coldfield

Following an IPU DieselCheck test Good Hope Hospital found that their diesel was heavily contaminated. It contained substances such as colloid carbon (a substance that can clog filters and causes poor combustion). This meant the hospital needed to act quickly as the consequences of a blackout at a hospital would be catastrophic.

Good Hope Hospital approached IPU with 7 unique fuel tanks, each in different locations including indoors, outdoors and underground. The test results had shown that all were showing signs of contamination. This is not uncommon as fuel degradation can occur no matter where it is stored.

In hospitals, banks and data centres power is critical. If the mains supply fails it’s vital they still have access to a constant source of electricity. Organisations such as these will typically install backup generators which require enough diesel to run the generators for hours, days or weeks.

However, as the generators will usually run for just short periods during maintenance schedules the diesel remains stagnant for long periods. This causes a huge risk as the fuel we buy has a reliability shelf life of just 6 to 12 months. Stored any longer and it becomes contaminated, threatening the reliability of backup systems.

The Solution

Thankfully Good Hope Hospital acted before disaster could strike. IPU’s ClearTank service removed the contamination and restored the fuel to quality standards EN590 and ISO 4406. The hospital found IPU’s ClearTank service to be entirely unobtrusive as no hazardous man-entry is required, storage tanks are cleaned simultaneously with the fuel and the generators remained online throughout.

ClearTank ensures:

  • Water is removed down to 200 parts per million or less as specified in EN590
  • Solid particulates such as soot, rust and colloid carbon are removed to 18/16/13 as advised by ISO 4406
  • Microbial growth is removed
  • Any sludge that may have settled at the bottom of the tank is broken down and filtered out.

“Clean, dry fuel is so important for our backup power systems. When we saw the results of our fuel test we knew we had to act. IPU has been excellent in restoring our diesel and in providing solutions that will allow us to keep our fuel clean going forward.”

The hospital has also taken the prudent step to protect themselves by installing IPU’s Diesel Defence on each of their tanks.

Diesel Defence combines filtration and circulation to keep fuel clean. The polishers circulate the diesel to prevent pockets of dirty fuel or water collecting in stagnant parts of your tank. Diesel Defence polishers are a ‘fit and forget’ solution – simply set it up once and it will run unassisted, month after month.
