TCQi Industrial
The TCQi is a high-performance industrial cooling tower designed in a compact counterflow cooling tower configuration with twin induced-draft fans. As part of our advanced fibreglass cooling tower range, the TCQi is engineered for reliable thermal performance, practical capacity control, and long service life in demanding environments.
The twin-fan arrangement allows staged airflow operation across varying loads, improving energy efficiency and providing operational resilience. When cooling demand is lower, one fan can be switched off via the building management system (BMS) to reduce energy use. If one fan is offline for maintenance, the cooling tower system can continue operating at partial capacity.
As an experienced cooling tower manufacturer and supplier, Tower Thermal designs each unit to deliver predictable performance, durable construction, and accessible maintenance.
Purpose of a cooling tower
The purpose of a cooling tower is to remove excess heat from water used in industrial processes, refrigeration systems, or HVAC cooling tower applications. Heat is rejected to the atmosphere through evaporative cooling, allowing the cooled water to be recirculated through the process or building system.
The TCQi provides an efficient solution where reliable heat rejection, operational flexibility, and manageable maintenance access are required.
What it’s for
The TCQi is suited to applications requiring a compact industrial cooling tower footprint with staged capacity control. Compared with single large fan designs, twin-fan towers offer improved redundancy and flexible operation across varying loads.
This cooling tower design is particularly useful where space constraints, maintenance accessibility, and predictable performance are priorities.
Key advantages
- Staged fan operation: operate one or both fans to match system load and improve energy efficiency.
- Operational resilience: maintain partial cooling capacity during maintenance or servicing.
- Compact counterflow configuration: ideal when site footprint is limited.
- Balanced airflow distribution: twin fans help maintain even air movement across cooling tower fill.
- Fibreglass (FRP) or stainless construction: corrosion-resistant structure suitable for demanding industrial environments.
- Retrofit-friendly installation: practical where lifting, access, or installation constraints exist.
Typical applications
- Commercial HVAC cooling tower systems
- Industrial process cooling
- Refrigeration and chilled water plants
- Mining, oil & gas, and heavy industry
- Food and beverage processing
- Data centres and mission-critical facilities
Cooling tower components and configuration options
Each TCQi cooling tower system is engineered to suit the project duty and site conditions. Configuration options may include:
- Single or multi-cell cooling tower arrangements for redundancy and future expansion
- Cooling tower fill selection to balance heat transfer efficiency and fouling tolerance
- Drift eliminator configuration to minimise water carryover
- Materials and corrosion protection suited to water quality and operating environment
- Fan and drive selections to meet noise, efficiency, and maintenance requirements
- Access platforms and safety systems for inspection, servicing, and cleaning
These design variables influence overall cooling tower performance, including range, approach, airflow requirements, and long-term operating efficiency.
Cooling tower sizing information
Accurate cooling tower sizing ensures reliable performance and efficient operation. When selecting a cooling tower, the following information is typically required:
- Heat load (kW) or hot and cold water temperatures with flow rate
- Project location and design wet bulb temperature
- Required cooling tower range and approach
- Available footprint, height restrictions, and installation constraints
- Noise limits and nearby receptors
- Water quality, filtration, and treatment strategy
- Electrical supply and preferred control method (fan staging, VSD, BMS integration)
Cooling tower servicing and lifecycle support
Beyond supply, Tower Thermal provides comprehensive cooling tower servicing and lifecycle support for industrial cooling towers. Services include inspections, performance testing, repairs, component replacement, and system upgrades.
This ensures cooling towers maintain reliable operation, regulatory compliance, and thermal performance throughout their operational life.
