The Fan Stack’s innovative design, unique fan layout and optimal controls allow for a 25% increase in energy efficiency when compared to the competition, reducing operational costs and improving PUE.
-
Capacity range
250kW - 1MW
-
Temperature control
Fan Stacks meet temperature requirements for any application, with options for low CHW coil approach temperatures.
-
Built-in electrical redundancy
Dual power feed connections with built-in Automatic Transfer Switch (ATS) for complete electrical redundancy.
-
Remote monitoring and diagnostics
Evaluate system performance and diagnose issues in real-time with remote monitoring from the local BMS or Excool HQ.
-
Simplified maintenance
The intelligent controls system continually monitors inbuilt variables, reducing day-to-day maintenance while forecasting and resolving issues before failings occur.
-
Redundant fan arrangement
The Fan Stack’s redundant fan arrangement provides extra capacity, reducing the load on each fan. The layout protects the unit in case of fan failure, as the other fans can easily ramp up while also meaning the fans run at a more efficient part of the fan curve.
-
In-built controls redundancy
UPS-backed controls system, providing comprehensive visibility and immediate response to black building events.
-
V-bank filters
Built to maximise efficiency, the Fan Stack product line has integrated V-bank filters to reduce pressure drops across the system, reducing the required fan power and energy consumption.
-
Expert controls
The Fan Stack offers customisable controls, including group control for dynamic airflow optimisation.
-
Quick-to-market delivery
Accelerate your project schedule with our market-leading delivery windows.
-
Strength and flexibility
Part of the ModulR line, Fan Stack units are highly customisable, allowing for greater capacity and alternative footprint arrangements. Fan Stacks have high-quality welded frames regardless of footprint configuration.
-
Optimised energy utilisation
The Fan Stack’s innovative design, unique fan layout and optimal controls allow for a 25% increase in energy efficiency when compared to the competition, reducing operational costs and improving PUE.
-
Cost-efficient investment
With low CAPEX requirements, we provide a financially accessible solution without compromising on quality or functionality.
