VVI / VVF Model
AXH air-coolers’ most economical cooler design and a superior alternative to a “radiator”
AXH air-coolers: VVI / VVF Model
-
Advantage Summary
- Inherently more efficient Forced draft design
- Ideally suited for multiple services including engine utility cooling along with oil and multi-stages of gas compression
- Narrow width and lower profile
- Section design facilitates piping
- Single, fan shaft design
- Enhanced safety with excellent visual inspection and access to critical moving parts
-
Multiple services in a single unit
The Type VV is commonly used for gas, lube oil and water cooling applications where recirculation of hot discharge air is not critical. They are available in virtually all fan sizes as small as 24 inches while their flexibility allows use in a wide range of special applications
-
Forced or Induced Draft Design
Type VV coolers are available in either a forced (VVF) or induced draft (VVI) configuration with horizontal air flow and can be configured to meet individual installation requirements. Propeller type air-foil fans with either fixed or adjustable pitch result in higher efficiency and lower fan horsepower.
-
Section Accessibility and Temperature Control
- Section Accessibility: The Type VV’s design provides greater section accessibility in applications requiring section replacement or change out. All sections are equipped with integral core guards for maximum protection of the exposed sections.
- Temperature Control: Adjustable aluminum shutters are an optional feature on all VV models and are located on the air inlet side of the sections in induced draft models for improved control of fluid outlet temperatures. Manual or automated aluminum shutters are available, offering superior air-flow control and improved operating efficiency by allowing independent louver adjustment over separate services.
-
Drive Options and Inspection and Maintenance
- Fans can be V-belt driven from an engine or compressor or adapted to a variety of drive types — direct, electric motor, or hydraulic.
- Standard single fan and blower pillow-block bearing assemblies on both fan and idler ensure proper alignment and easy maintenance when engine or compressor driven. Fan and idler bearings are also interchangeable on most standard units. Fans are provided with removable access guards for ease of inspection and maintenance.
When to choose the VVI / VVF Model
Cost-Effective Horizontal Air Cooler
The VVI/VVF model horizontal air-cooled heat exchangers are engineered for both thermal efficiency and mechanical robustness, ensuring they meet the stringent demands of various industries. The VVI/VVF air coolers offers one of the most economical designs available, providing a cost-effective solution for industrial cooling needs. These heat exchangers are ideal for applications in power generation, petroleum refining, chemical processing, gas transmission, and oil and gas production. Their optimized design ensures they meet the high standards necessary for critical industrial processes. The Type VV heat exchanger’s design offers enhanced accessibility to individual sections, making it easier to perform section replacements or changes when needed. This feature is particularly valuable in applications where maintenance or upgrades are frequent.
