BAP Cooling Tec specializes in Aluminum Radiators and Bar-Plate Heat Exchangers for industries, including construction machinery, diesel generators, air compressors, and hydraulic systems.

Our aluminum radiators use bar-plate (plate-bar) construction for superior heat dissipation, lightweight design, and long service life. Each unit is engineered to meet your specific cooling requirements — inlet/outlet size, mounting dimensions, flow rate, and pressure specifications.

Key Features:

• Material: High-quality aluminum alloy (AA3003, AA6063)
• Core Type: Bar-plate (plate-bar) structure
• Fin Type: Offset strip fin, plain fin, wavy fin
• Applications: Excavators, loaders, bulldozers, generators, compressors
• Cooling Medium: Water/glycol, hydraulic oil, charge air
• Customization: OEM/ODM supported, drawings accepted

All products are pressure-tested before shipment. MOQ flexible for custom orders.

BAP Cooling Tec is a specialized manufacturer of custom aluminum plate-bar radiators and bar-plate heat exchangers, engineered for demanding industrial cooling applications. Our radiator products serve construction machinery, diesel generator sets, air compressors, hydraulic power units, and mobile equipment across global markets. Every unit is designed and manufactured to deliver maximum heat dissipation in compact form factors, ensuring your equipment operates within safe temperature ranges under continuous heavy-duty loads.

Core Technology: Vacuum Brazed Aluminum Radiators and Bar-Plate Heat Exchangers

Our radiators are built using vacuum brazed Aluminum Radiators and Bar-Plate Heat Exchangers (also known as plate-fin) core technology — the industry benchmark for high-performance thermal management. Unlike traditional tube-and-fin designs, our plate-bar architecture delivers:

• Superior Heat Transfer Efficiency: The corrugated fin structure between flat plates creates an exceptionally large surface-area-to-volume ratio, maximizing convective heat transfer while keeping overall dimensions compact.
• Robust Structural Integrity: Aluminum Radiators and Bar-Plate Heat Exchangers fuses all components into a single monolithic aluminum structure at temperatures exceeding 600°C. This eliminates mechanical joints that can fatigue or leak under thermal cycling and vibration — critical factors in mobile machinery applications.
• Lightweight Design: Aluminum construction reduces weight by 40–60% compared to equivalent copper-brass radiators, lowering fuel consumption and easing equipment handling.
• Corrosion Resistance: All Aluminum Radiators and Bar-Plate Heat Exchangers alloy components are compatible with modern engine coolants, including extended-life organic acid technology (OAT) formulations widely used in Tier 4/Stage V compliant engines.

Application-Specific Engineering

We don’t produce off-the-shelf generic radiators. Each Aluminum Radiators and Bar-Plate Heat Exchangers is engineered around your specific application parameters:

Construction Machinery & Earthmoving Equipment:
Excavators, loaders, bulldozers, and motor graders generate immense waste heat from diesel engines and hydraulic systems operating in dusty, high-ambient environments. Our radiators feature optimized fin pitch (typically 1.4–2.0mm FPI) to balance airflow resistance against dust-clogging risk, with optional protective mesh screens for severe conditions.

Diesel Generator Sets:
Standby and prime-power generators require reliable cooling during prolonged operation at rated load. We design radiators with elevated thermal margins (typically 15–20% above calculated heat rejection requirements) to accommodate derating factors including high ambient temperature, altitude compensation, and fouling buildup over service life.

Air Compressor Systems:
Screw and reciprocating compressors demand efficient aftercooling and oil cooling to maintain volumetric efficiency and prevent premature component wear. Our integrated radiator assemblies can combine charge-air cooling and engine coolant circuits into a single compact package.

Hydraulic Power Units:
Mobile hydraulic systems — from crane booms to agricultural implements — rely on oil coolers to maintain hydraulic fluid viscosity within optimal ranges. Our hydraulic oil cooling radiators are sized using proprietary thermal calculation methods accounting for peak pressure drops, flow rate variability, and worst-case ambient conditions.

Custom Design & Manufacturing Process

Every BAP Cooling Tec Aluminum Radiators and Bar-Plate Heat Exchangers project follows a structured development workflow:

1. Thermal Specification Review: We analyze your heat load data, flow rates, allowable pressure drop, space envelope, and operating environment.
2. Core Sizing & Selection: Using industry-standard thermal calculation software combined with our empirical database of proven designs, we determine optimal core dimensions, fin type, fin height, and pass arrangement.
3. Prototype Fabrication: A first-article prototype is produced for dimensional verification and bench testing where required.
4. Pressure Testing: 100% of production units undergo pneumatic leak testing at 1.5× working pressure minimum, with hydrostatic test options available upon request.
5. Quality Inspection: Visual inspection, dimension verification, and packaging quality check before shipment.
