VOLGA HVAC® – Flat-Type Dry Coolers

Compact, Energy-Efficient Air-Cooled Units for Closed-Loop Cooling Systems

Overview

The VOLGA HVAC® Flat-Type Dry Coolers are designed for high-performance air cooling in closed-loop industrial applications. Utilizing a multi-row finned tube design with direct-drive axial fans, these dry coolers ensure maximum heat transfer efficiency while maintaining a compact footprint.

Cooling Operation

A continuous flow of process fluid passes through multiple tube circuits, while ambient air is drawn across the external finned surfaces by low-noise, high-efficiency fans. This method offers a water-free cooling alternative, reducing maintenance and operational costs.
