Hylita Surface Air Coolers: Advanced Closed-Loop Cooling Systems
The perfect hybrid of air cooling and evaporative efficiency. Compact, Corrosion-Resistant, and Custom-Engineered.
Surface Air Coolers are essential industrial heat exchange equipment designed for high-efficiency thermal management. By circulating fluids through a precision-engineered core, they utilize advanced heat transfer mechanisms to rapidly cool or heat the target medium.
Working Principle
The operation relies on the principles of thermal conduction and convection. As the process fluid is injected into the Surface Air Cooler, thermal energy is efficiently transferred from the fluid to the heat exchange surface (typically finned tubes). This heat is then dissipated into the external environment, lowering the fluid temperature via the cooler's optimized structure.
Core Functions
The primary function is versatile fluid cooling. These units are engineered to handle a diverse range of media, including process water, air, and industrial gases.
Additionally, they offer dual functionality: they can serve as process heaters. By circulating high-temperature fluids (such as steam or thermal oil) through the system, the Surface Heat Exchanger effectively transfers heat to the target medium, meeting flexible industrial requirements.
PRODUCT OVERVIEW
High-Performance Custom Cooling Solutions
Hylita Surface Air Coolers (SAC) are engineered for the most demanding industrial environments. By integrating traditional air cooling with closed-circuit evaporative technology, our units deliver:
- Maximum Cooling Capacity in a compact footprint.
- Minimal Operation Costs (reduced water and electricity usage).
- Zero Contamination Risk due to the closed-loop design.
Whether you need to cool process fluids in Dry Mode or enhance performance with Wet Mode during peak heat, Hylita systems adapt to your ambient conditions for optimal thermal efficiency.
HOW IT WORKS
Thermodynamic Efficiency - The Hylita SAC operates on the principle of direct thermal conduction and convection:
Primary Circuit
Hot process fluid flows through the internal tube bundle.
Heat Transfer
Heat is rapidly conducted from the fluid to the tube wall and extended fin surface.
Heat Rejection
Ambient air (enhanced by water spray in Wet Mode) passes over the fins, removing heat and discharging it into the atmosphere.
Hylita Surface Air Coolers are the industry standard for robust and efficient cooling in diverse industrial processes. Our advanced designs, featuring corrosion-resistant materials and high-performance finned tube technology, are engineered to meet the rigorous demands of various sectors.
