Choosing the right cooling tower configuration is a lot like choosing between a single-lane road and a multi-lane highway. Both will get you where you need to go, but the experience—efficiency, reliability, and flexibility—can be very different. When it comes to a 170 ton cooling tower, one of the most important design decisions is whether to use a single cell or a multi-cell configuration.
This choice directly affects cooling performance, energy consumption, maintenance strategy, and long-term operating cost. In this article, we’ll break down the differences in a clear, practical way to help you choose the right configuration for your industrial or commercial application.
A 170 ton cooling tower sits right in the sweet spot of industrial cooling capacity. It’s large enough that efficiency and redundancy matter, but still compact enough to allow multiple design approaches. At this scale, cell configuration is no longer a minor detail—it’s a strategic decision that can influence system performance for decades.
A 170 ton cooling tower is designed to reject approximately 170 refrigeration tons of heat from a circulating water system. It removes heat primarily through evaporative cooling, allowing chillers, condensers, and industrial processes to operate within safe temperature limits while maintaining energy efficiency.
These towers are widely used in HVAC systems, manufacturing plants, chemical facilities, power stations, and data centers.
Before comparing options, it’s important to understand what “cell configuration” actually means in cooling tower design.
A single cell cooling tower is a self-contained unit that handles the full cooling load within one structure. It includes one fan system, one water distribution system, one fill section, and one basin.
A multi-cell cooling tower divides the total cooling capacity into two or more smaller, independent cells. For a 170 ton system, this often means two cells (for example, 2 × 85 tons), each capable of operating independently or together.
At higher capacities, configuration choices impact far more than footprint. They influence:
System redundancy
Part-load efficiency
Maintenance flexibility
Energy costs
Operational reliability
Choosing the wrong configuration can result in unnecessary downtime or long-term inefficiencies.
A single cell 170 ton cooling tower is often chosen for its simplicity and lower upfront cost.
Single cell designs use one fan and one motor to move air through the entire tower. Water distribution is centralized, making installation faster and piping layouts simpler.
Single cell towers are commonly used in facilities with steady cooling demand, such as small industrial plants or standalone commercial HVAC systems.
A single cell configuration is ideal when:
Cooling load is stable
Space is limited
Redundancy is not critical
Simplicity is a priority
Multi-cell configurations introduce flexibility and control into the cooling system.
Each cell has its own fan, motor, and water distribution system. Cells can operate independently or together, depending on cooling demand.
Instead of running one large fan continuously, multi-cell systems allow operators to stage capacity—running one cell during low load and both during peak demand.
Multi-cell designs are ideal when:
Cooling demand fluctuates
Continuous operation is critical
Energy efficiency is a priority
Future expansion is expected
Both configurations can deliver 170 tons of cooling, but performance differs under real operating conditions.
Multi-cell systems often maintain better approach temperatures during part-load operation because airflow and water flow can be better matched to demand.
Single cell towers typically rely on fan speed control or throttling, while multi-cell systems can simply shut down unnecessary cells—an inherently more efficient strategy.
Energy efficiency is one of the strongest arguments for multi-cell configurations. Operating one cell instead of two during low-demand periods can significantly reduce fan energy consumption, which adds up to meaningful savings over time.
A single cell cooling tower has one major drawback: a single point of failure. If the fan or motor fails, the entire system is offline.
Multi-cell towers offer built-in redundancy. If one cell requires maintenance or experiences a fault, the other can continue operating at reduced capacity.
Maintenance planning looks very different for each configuration. Single cell towers usually require a full system shutdown for major service, while multi-cell systems allow maintenance on one cell while the other remains operational.
Single cell towers typically require less footprint and simpler piping. Multi-cell towers need more space, but they offer better airflow distribution, easier access for maintenance, and improved long-term operability.
Single cell towers generally have a lower initial purchase price. However, multi-cell configurations often deliver lower lifecycle costs thanks to energy savings, reduced downtime, and extended equipment life.
Multi-cell systems distribute mechanical loads across multiple fans, reducing vibration and enabling quieter operation—especially when paired with variable frequency drives.
Manufacturing plants, data centers, chemical facilities, and power plants often prefer multi-cell configurations due to reliability and load variability. Commercial HVAC systems with stable demand frequently choose single cell designs.
Mach Cooling (https://www.machcooling.com/) provides both single cell and multi-cell 170 ton cooling tower solutions engineered for efficiency, durability, and long-term performance. Their designs emphasize optimized water distribution, high-efficiency fill, and robust materials to minimize scaling, reduce energy consumption, and support flexible operation across diverse industrial applications.
Ask yourself a few key questions:
Does my system require redundancy?
Will cooling demand vary significantly?
Is long-term energy cost more important than initial investment?
Your answers will usually point clearly toward either a single cell or multi-cell solution.
There is no universal answer when comparing single cell vs multi-cell 170 ton cooling tower configurations. Single cell towers offer simplicity and lower upfront cost, while multi-cell systems provide flexibility, redundancy, and superior part-load efficiency. By carefully evaluating operational needs and working with experienced manufacturers like Mach Cooling, you can select a configuration that delivers reliable, cost-effective cooling performance for years to come.
