GT Series Cooling Towers
Modular, energy-efficient cooling towers designed for rapid deployment and peak performance
Aggreko’s patented GT cooling towers are built to solve one of the biggest challenges in temporary cooling: how to deliver powerful, scalable cooling with faster setup, greater energy efficiency, and a smaller site footprint.
The GT series includes multiple models of compact cooling towers to match your configuration and capacity needs. The ultra-portable GT10 is perfect for small-scale or fast-turnaround jobs, arriving trailer-mounted and ready to install without cranes or forklifts. The GT20 and GT40 models are modular, containerized towers engineered for larger loads and long-term industrial reliability.
From 150 to 1.5 million+ GPM, GT towers adapt to your needs with variable-speed fans, built-in safety features, and 24/7 remote monitoring to keep performance high and downtime low.
Industrial and commercial cooling tower applications
Our innovative cooling tower solutions are ideal for:
- Emergency cooling when permanent towers fail or go offline
- Planned maintenance or plant turnarounds that require supplemental cooling
- Capacity expansions or seasonal demand spikes in space-constrained environments
