Project

Multi-Genset Installation – Cummins QSK60-G4 Engines

Engine Size

QSK60-G4 - per unit (3 units total)

Sector

Healthcare / Hospital Infrastructure

Project Overview

This project required the installation of airless SCR systems on three Cummins QSK60-G4 generator sets in a medical facility that remained operational throughout the retrofit. The challenge involved three unique installation layouts while ensuring seamless integration and shared DEF delivery.

Solution Provided

E.I. Williams/IMS design cost-effective customized solution by providing airless SCR solution using a shared DEF infrastructure. For instance, in this project, a central DEF tank with remote fill capability was installed to support all three engines simultaneously. The control logic included closed-loop dosing and smart diagnostics, ensuring full emissions compliance and operational reliability.
