Heavy‑Duty HT‑LT Dry Cooler Remote Radiator For 2000kW / 2500kVA Gas Power Generator
Application Overview
Unit rating: 2500 kVA gas‑fired generator set (~2000 kW prime power)
Fuel adaption: Natural gas, biogas, landfill gas, coal‑bed methane
Cooling solution: Remote‑mounted dual‑circuit dry‑cooling radiator, separated HT (high‑temperature) & LT (low‑temperature) closed glycol‑water loops
Operation mode: 24/7 continuous base‑load for CHP / independent power plant projects
Cooling Circuit Function
HT Circuit (Jacket Water Cooling)
Duty: Cool engine cylinder liner & cylinder head jacket water
Typical operating range: Supply 85‑95 °C / Return 75‑85 °C
Heat rejection: Main engine jacket waste heat; stabilizes engine working temperature, minimizes thermal stress
LT Circuit (Charge‑air & Lube Oil Cooling)
Duty: Cool turbo charge‑air intercooler, engine lube oil heat exchanger
Typical operating range: Supply 30‑40 °C / Return 40‑55 °C
Benefit: Precise intake air temperature control, preserves power output, optimizes combustion and emission performance
Core Design Features
Fully‑separated dual‑loop construction: HT and LT circuits are independent, no internal mixing, matches OEM dual‑circuit cooling requirement for large‑bore gas engines
Remote layout: Heat rejection unit installed outside engine building; releases engine‑room space, reduces indoor heat accumulation and noise
EC variable‑speed axial fan array: Fan speed auto‑modulated by coolant temperature and ambient temperature; lowers auxiliary power consumption, reduces noise at partial load
Heavy‑duty anti‑corrosion coil options: Epoxy‑protected aluminium fins / stainless steel tubes, resistant to corrosive airborne contaminants from biogas & landfill gas sites
Zero water consumption dry cooling: No cooling tower water loss; ideal for water‑scarce project locations
Custom engineered: Flow rate, pressure drop, flange connections, mounting dimension tailored to genset cooling requirement; with temperature sensors, air‑vent & drain valves pre‑fitted
Main Advantages
Avoids power derating under high ambient temperature, maintains full‑load continuous running for 2500 kVA gas genset
Solves poor ventilation issue for containerized / compact engine‑room installations
Lower on‑site noise; easy access for inspection and maintenance
Long service life for harsh gas‑fuel power‑plant environment
Supports CHP waste‑heat recovery system integration
