HJS are the first retrofit exhaust system manufaturer to secure Energy Saving Trust
HJS are the first retrofit exhaust system manufacturer to secure Energy Saving Trust (EST) certification for all power bands of fixed and variable speed Non Road Mobile Machinery (NRMM) applications. This includes approval for Stage 3b and Stage 4 engines where a compliant OE DPF is already fitted, and an HJS SCR system is retrofitted to achieve Stage 5.
HJS have worked tirelessly over the last 2 years with the Swiss Association VERT and have undertaken strict in-service testing in order to gain this accreditation.
In the current climate of uncertainty where compliant machinery is not widely available, the HJS SCR/T system gives NRMM owners and operators a cost-effective and timely alternative to purchasing new Stage 5 machinery.
Contact us today to discuss retrofitting your existing equipment to gain Stage 5 compliance. This is essential for the Greater London Authority NRMM low emission zone, on key infrastructure projects such as HS2, and on a growing number of key construction sites across the UK.
