V‑Shaped All‑in‑One HT LT Remote Radiator Dry Cooler For MWM TCG2020 TBG620 Gas Engines
HT Circuit (Jacket Water)
Function: Cool engine cylinder jacket & cylinder head
Operating temp: Supply 84‑94°C / Return 74‑84°C
Purpose: Dissipate jacket heat, stabilize engine thermal balance, reduce thermal fatigue for long‑time gas‑engine operation
LT Circuit (Charge‑air + Lube Oil)
Function: Cool charge‑air intercooler and lube oil heat exchanger
Operating temp: Supply 31‑39°C / Return 41‑54°C
Purpose: Stabilize intake air temperature, avoid power derating, optimize combustion efficiency and extend oil service life
Key Design Features
All‑in‑one V‑shape integrated structure: Both HT and LT heat‑exchanger coils are assembled inside one V‑frame cabinet. Single unit delivery & installation, saves site space compared with two separate radiators.
Strictly independent dual‑loop design: HT and LT circuits have separate tube bundles, piping and connection flanges, zero internal cross‑mixing, fully comply with MWM original cooling requirements for TCG2020 / TBG620.
V‑angle coil arrangement: Optimized air intake path, high heat‑exchange efficiency; compact footprint, well‑adapted for container‑mounted and outdoor skid‑mount layout.
Corrosion‑resistant coil options: Epoxy coated aluminium fins / stainless steel tubes; hot‑dip galvanized steel frame, resisting corrosive airborne contaminants from biogas / landfill gas sites.
EC variable‑speed fan bank: Fans automatically modulate speed responding to coolant temperature and ambient air temperature; cut auxiliary power consumption and lower noise under partial load.
Zero‑water‑consumption dry cooling: No cooling tower required, suitable for locations with water shortage or poor water quality.
Customized interface: Flow rate, pressure drop, flange sizes, mounting points engineered to match MWM specification. Pre‑fitted air‑vent valves, drain ports and sensor mounting ports. Optional lifting lugs, service walkway for heavy‑duty outdoor installation.
Main Benefits
Maintain full‑power output of MWM TCG2020 & TBG620 gas engines under high ambient temperature, prevent thermal derating.
All‑in‑one V‑shape design simplifies civil work, piping layout and on‑site commissioning versus split‑unit solutions.
Remote heat rejection reduces engine‑room temperature and noise, improves working environment for containerized CHP units.
Robust anti‑corrosion construction extends service life for harsh biogas‑plant operating conditions.
Low OPEX, no water makeup; VRCOOLER provides thermal calculation report, dimensional drawing and complete technical documentation.
