HT‑LT Cooler For MAN Generator, Custom Build Based On Drawing & Sample
Dual‑circuit high‑temperature & low‑temperature cooler specially for MAN diesel & gas generator sets, fit MAN E2676, E2876, L16/24, L21/31, 27/38 series genset engines.
Independent segregated HT and LT cooling coils inside one unit, no thermal cross‑interference. Supports OEM replacement and full custom build based on drawing, datasheet or old sample, for power plant, marine, offshore and stationary continuous‑run generator projects.
| Circuit | Cooling Target | Typical MAN working condition |
|---|---|---|
| HT High‑Temperature Circuit | Engine jacket water, cylinder liner & cylinder head cooling | Inlet ~95℃,Outlet ~85℃;Bear main engine heat load |
| LT Low‑Temperature Circuit | Charge air cooler / CACW, lube oil cooler, auxiliary circuit cooling | Inlet ~50‑60℃,Outlet ~40‑45℃;Control intake air temperature, reduce NOₓ emission |
Working Loop Matching (MAN typical system)
Hot charge air from turbo → enter CACW air side
LT low‑temp coolant (40‑60℃) from HT‑LT shell&tube cooler flows through CACW water side
Charge air temperature drops, air density rises; reduce engine NOₓ emission, improve fuel efficiency
Heated LT coolant flows back to HT‑LT shell‑tube cooler for heat dissipation to plant secondary cooling water
