The 100BP western blender of Huabei Oilfield stopped work for several years due to failures. In the past several years, the diagnosis and maintenance conducted by many professional companies all failed to make the machine run normally. 

At the end of April, 2004, Huabei Oilfield contacted Jereh. In May, Jereh sent two engineers with skilled experience in maintaining blenders to Huabei Oilfield. At that time, the electric and hydraulic components had been badly damaged. Overcoming one difficulty after another, Jereh's engineers brought the circuit board, the hydraulic pump and the control valve back to work. By the end of May, the repairing work and debugging had been finished.

The outstanding techniques, the Jereh Spirits and the rapid delivery were confirmed once again. "Second to none" is the highest honor that Huabei Oilfield gave Jereh.
