Hybrid Dry Coolers
Hybrid dry cooling combines dry operation with targeted evaporative support, managed by an intelligent control system, to maintain peak performance in challenging ambient conditions. The HTK Series increases available capacity when temperatures exceed dry cooling limits. The controller automatically regulates operating modes, supporting stable, responsive performance without continuous wet use.
What are Hybrid Dry Coolers?
The HTK Hybrid Dry Cooler Series is well suited to applications where performance, reliability and resource efficiency must be balanced within real-world operating constraints. Its hybrid operating principle enables stable cooling across varying ambient conditions, load profiles and regulatory environments.
Designed for performance and control
The HTK Series is designed to deliver stable capacity and controlled performance under demanding operating conditions. Key design characteristics include:
How the HTK Hybrid Dry Cooler series operates
The HTK Series operates primarily in dry mode, with controlled evaporative enhancement activated only when required. This hybrid approach increases cooling capacity during peak conditions while maintaining defined performance limits and minimizing water use through system-level control.
