Copper-brass radiator repair, core recoring, and new radiator supply for all Kirloskar DG set models from 125 KVA to 750 KVA. KG Series, SL90 Series, DV Series. Pickup & delivery across Mumbai. 6-month warranty on all work.
Kirloskar is India's most widely used diesel generator brand — from hospitals and factories to warehouses and commercial complexes. Kirloskar DG sets from 125 KVA to 750 KVA use copper-brass radiators that are well-suited for India's climate and continuous-duty operation. At Ajanta Radiators, we have deep experience servicing Kirloskar radiators across the KG, SL90, and DV series at our Worli, Mumbai workshop.

On older KG125W and KG160W models, the brass top tank develops hairline cracks at the weld joint with the header plate after 8–10 years of continuous operation. We re-solder and pressure test to restore the joint.
SL90 radiators on 250–500 KVA sets running 24×7 accumulate calcium and rust scale inside copper tubes, reducing coolant flow by up to 40%. We flush, descale, and restore full cooling capacity.
Inlet and outlet hose fitting joints develop leaks from vibration and age. We re-seat and solder the fittings, or replace the entire tank nipple assembly.
DV10 and DV12 series (625–750 KVA) radiators develop tube-to-header joint failures from higher thermal cycling at large load. We replace individual tubes or fully recore where damage is extensive.
HA and 6R series radiators lose cooling capacity as fins flatten and tubes scale up over years. A full recore with new copper-brass core restores original cooling performance.
Bottom tanks crack or warp from water hammer or rough coolant draining. We fabricate and replace brass bottom tanks in-house at our Worli workshop to exact Kirloskar specifications.

Yes — if only specific tubes or joints have failed, we repair those without a full recore. We recommend recoring only when the core has multiple failures, heavy scale buildup, or overall corrosion that makes individual tube repair uneconomical. We always advise honestly after inspection.
Internal scale buildup in the copper tubes is the most common cause of Kirloskar radiator overheating without visible leaks. The core becomes progressively blocked, reducing coolant flow and cooling capacity. Flushing and descaling often resolves this without needing a full repair or recore.
