Description

Information

The Horizontal Draft Air Cooler is an efficient, reliable, and space-optimized air-cooled heat exchange solution designed for industrial, power generation, refinery, and process cooling applications. Featuring a horizontal airflow configuration, the unit draws ambient air laterally across the heat exchanger coil, delivering stable performance in environments with limited vertical space or strict noise requirements.

Engineered for high thermal efficiency and long-term durability, the system adopts heavy-duty finned tube bundles, high-performance axial fans, and intelligent control options to ensure consistent cooling under varying load and climate conditions.

Advantages

● High thermal efficiency with optimized coil and fan design

● Lower operating cost due to horizontal draft and energy-saving controls

● Compact layout suitable for space-restricted installations

● Stable performance under variable ambient conditions

● Easy installation and maintenance through ground-level access

● Low noise operation ideal for industrial and urban sites

Applications

● Oil & Gas: Cooling refinery streams, natural gas, and LNG.

● Power Generation: Condensing steam turbines and cooling auxiliary systems.

● Chemical Industry: Managing exothermic reactions and vapor condensation.

● Renewable Energy: Supporting geothermal and biomass energy systems.

● HVAC & Manufacturing: Industrial heat recovery and process cooling.

Optional Configurations

● Compliance with ASME and API 661 standards

● Forced Draft or Induced Draft fan arrangements

● Horizontal or Vertical air flow design

● Smart Controls (temperature sensors, variable speed fans)

● Explosion-Proof, Low-Noise, or Marine-Grade Designs

● Dry/Wet Hybrid System for Enhanced Performance in high ambient temperatures

● Custom painting & corrosion protection

Extended Surface Fin Types Available

● L-foot fin (basic embedded fin, economical and widely used for general-purpose cooling)

● Overlapped L-foot fin (LL type): provides better corrosion resistance by overlapping fin foot over the tube surface

● Embedded G-fin: fins mechanically embedded into the tube surface for improved thermal contact and durability

● Knurled L-foot fin (KL type): uses a knurled surface on the tube to enhance mechanical bonding between fin and tube

● Extruded fin: formed by extruding aluminum over the tube for maximum corrosion resistance and strength, ideal for harsh environments

● Bimetallic finned tubes: e.g., aluminum fins on carbon steel or stainless steel tubes, combining thermal conductivity with structural or corrosion benefits

● Custom fin materials and geometries available upon request

Header Types Available

● Plug-type header (for compact or low-cost design)

● Removable cover plate header (for easy inspection and maintenance)

● Removable bonnet-type header (for higher-pressure applications with external access)

● Manifold-type header (for multi-pass or special flow arrangements)
