Disparate Cooling Systems
Multiple cooling loops. Multiple towers. Multiple pumps. No clear strategy.
Many legacy manufacturing sites operate several independent cooling systems that have evolved over time, often without a unifying design basis.
The result is duplication, inefficiency, complexity and hidden cost.
Vistech helps manufacturers evaluate and centralise cooling infrastructure to reduce energy use, simplify operation and improve resilience.
If You Have Three Cooling Systems, You Probably Only Need One (or Two)
Many sites didn't plan to have multiple cooling systems. They evolved through:
- New production lines added over time
- Emergency plant installations
- Supplier-led equipment changes
- Building expansions
- "Temporary" solutions that became permanent
Disconnected Cooling Systems Multiply Cost
Operating multiple independent cooling systems often results in:
Instead of one optimised system, the site runs several under-optimised ones. This increases both operating cost and operational complexity.
Common Signs Your Cooling Systems Are Disparate
You may have a centralisation opportunity if:
- Different buildings have separate cooling towers
- Production lines operate on independent loops
- Multiple small chillers operate inefficiently
- Each department "owns" its own cooling plant
- Systems were added during expansions
- Control strategies differ across plant
- There is no central load visibility
- Pumps run continuously in multiple areas
- No ability to share capacity between systems
- Maintenance teams manage multiple plant types
Why Disparate Systems Develop Over Time
Cooling infrastructure often evolves reactively:
Reactive Additions
One line overheats, install dedicated plant
Building Growth
New building constructed, install separate system
Packaged Solutions
Supplier provides packaged cooling, runs independently
Temporary Fixes
Old plant unreliable, add temporary unit that becomes permanent
What Centralised Cooling Delivers
When designed correctly, centralised cooling systems can provide:
- Load diversity and improved efficiency
- Improved part-load performance
- Reduced total installed capacity
- Lower pumping energy
- Improved control and automation
- Improved resilience through shared redundancy
- Simplified maintenance strategy
- Clearer system knowledge and visibility
- Lower total cost of ownership
Centralisation turns multiple independent systems into a coordinated strategy.
Centralisation Only Works If Engineered Properly
Centralising cooling is not just connecting pipes together. If done poorly, it can create:
- Hydraulic instability
- Insufficient pressure to remote loads
- Control conflicts
- New bottlenecks
- Unexpected downtime risk
Vistech designs centralisation projects from the process backwards, defining:
- Total site demand
- Load diversity
- Distribution strategy
- Pump staging
- Redundancy philosophy
- Phased implementation strategy
Typical Outcomes After Centralisation Projects
Delivered Without Major Production Disruption
Centralisation projects are typically designed to be installed in phases, built alongside live systems, tied in during controlled shutdown windows, and implemented without extended downtime.
Production protection is designed into the scope from the outset.

When a FEED Study Is the Next Step
Where centralisation represents a significant capital project, we progress to a FEED study to define:

Design basis, system architecture, hydraulic modelling, mechanical/civil/electrical/controls scope, phased delivery plan, commercial payback model.
This protects capital and reduces production risk.
Are Multiple Cooling Systems Increasing Your Costs?
If your site operates several independent cooling loops, towers or chillers, there is often an opportunity to simplify and optimise.
We can help determine whether centralisation is commercially and operationally beneficial.

-
Does centralisation always reduce cost?
Not automatically. It must be engineered correctly, with full understanding of load diversity and hydraulic constraints.
-
Is centralisation suitable for food manufacturing?
Yes, when designed correctly. Hygiene, resilience and control strategy must be integrated into the design.
-
Can it be implemented without shutting down production?
Often yes. Phased installation and short tie-in windows are typically used.
