Intercooler Radiator for NPT5 Locomotive Air Compressor，NPT5-51-04C

1. Adapt to the overall parameters of the host (NPT5 air compressor benchmark):
Air compressor type: three cylinder, two-stage compression, air-cooled reciprocating piston type
Rated volumetric flow rate: 2.4 m ³/min
Rated exhaust pressure: 900 kPa (9 bar)
Rated speed: 1000 r/min
Piston stroke: 130 mm
Cooling method: forced air cooling (equipped with NPT5-60-00A-1 cooling fan assembly)
2. NPT5-51-04C radiator body parameters:
function and role
After the first stage compressed high-temperature air enters the radiator for cooling, it then enters the second stage cylinder for compression, reducing the exhaust temperature, improving the efficiency of the air compressor, and protecting the cylinder seals. Complete cooler assembly NPT5-51-00 is composed of upper manifold NPT5-51-01A and lower manifold NPT5-51-02A
structural material
Heat dissipation core: purple copper fins+copper tube welding
Box body: cast aluminum/steel plate stamped sealed shell
Sealing gasket kit: NPT5-51-05 upper manifold gasket
Interface Specification
First stage inlet and second stage outlet flange docking NPT5 air compressor manifold
The air-cooled side is matched with a cooling fan for forced convection heat dissipation
Operating conditions
Primary intake temperature: ≤ 160 ℃
Cooling exhaust temperature: ≤ 60 ℃
Allowable working environment temperature: -40 ℃~+45 ℃ (outdoor working conditions for railway locomotives)
