HJS delivers proven emissions upgrade solutions that enable genset owners to achieve Stage V compliance quickly, cost-effectively, and with minimal disruption. For Stage II or IIIA gensets, tightening environmental regulations no longer require asset replacement. HJS retrofit systems upgrade existing engines to meet current emissions standards while extending operational life.
Designed to significantly reduce Nitrogen Oxides (NOₓ) and Particulate Matter (PM), HJS upgrades are suitable for both stationary and mobile generators. The system combines advanced aftertreatment technologies, including a high-efficiency Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR), and a Diesel Oxidation Catalyst (DOC). Precisely controlled AdBlue injection converts harmful exhaust gases into nitrogen and water, delivering reliable emissions performance without compromising engine operation.
A recent upgrade at HJS’s Swindon facility demonstrates how non-compliant gensets can be successfully future-proofed. An Stage 3a 200Kva Genset with an FPT engine and over 7000 operation hours was upgraded from Stage III to fully Stage V compliant, providing a cost-effective alternative to full replacement while meeting current regulations.
HJS SCR/SCRT systems are engineered for durability and low maintenance, with routine AdBlue refilling clearly indicated via the HJS service display to ensure maximum uptime. All HJS Stage V retrofit systems are approved for NRMM Low Emission Zones and accredited by the Energy Saving Trust, giving operators confidence in long-term compliance.
Backed by proven DPF and SCR technologies, HJS supports cleaner air, improved public health, and future-ready emissions compliance. As members of AMPS and the UKGSA, HJS remains at the forefront of emissions control for diesel power generation.
