TCQi Counterflow Twin Fan
The TCQi is an Industrial Counterflow Cooling Tower with a twin-fan, induced-draft configuration. Two fans allow staged airflow control across operating loads and provide resilience if one fan is offline. A Twin Fan configuration also helps to manage efficiency by allowing your BMS to switch off one of the fans while the cooling requirements are low.
What it’s for
Use the TCQi where you want a compact counterflow tower layout, practical capacity control, and straightforward maintenance access. It suits applications where footprint, redundancy, and predictable performance matter more than a single large fan.
Key advantages
- Staged operation: run one or both fans to match load and reduce unnecessary power use.
- Operational resilience: maintain partial cooling capacity during planned maintenance.
- Compact counterflow form factor: useful when plan area is constrained.
- Balanced airflow: twin fans can help distribute air more evenly across the fill.
- Retrofit-friendly: suitable where access, lifting, and installation constraints drive the design.
Typical applications
- Commercial HVAC and building services
- Industrial process cooling
- Refrigeration plants
- Mining, oil & gas, food & beverage, and data centres
Configuration options
Each TCQi is selected to match the duty and site constraints. Options typically include:
- Single or multi-cell arrangements for redundancy and future expansion
- Fill selection to balance thermal performance and fouling tolerance
- Drift control configuration to reduce carryover
- Materials and corrosion protection to suit water quality and environment
- Fan and drive selections aligned to noise, efficiency, and maintenance expectations
- Access and safety provisions to support inspection and cleaning
What we need to size and quote
- Heat load (kW) or hot/cold water temperatures and flow rate
- Project location (design wet bulb) and operating profile
- Available footprint, height, and any lifting/access limits
- Noise constraints (nearest receptors and time-of-day limits)
- Water quality, filtration approach, and treatment regime
- Electrical supply details and control preference (staging/VSD/BMS integration)
Support and lifecycle services
Tower Thermal supports cooling towers with parts, repairs, performance testing, audits, inspections, and upgrade work to keep equipment reliable over its service life.
