Problems We Fix
If your cooling system has evolved over 20 years, it’s almost certainly wasting money.
Vistech helps established UK manufacturers uncover and solve the hidden inefficiencies and resilience risks inside legacy cooling infrastructure - typically identifying 10–30% energy saving opportunities.
For manufacturing sites with >500kW cooling load and >£100m turnover.
Most Cooling Systems Are Not Optimised - They’re Just Operational
Cooling systems rarely fail all at once. They degrade slowly:
- Pumps run harder than they need to
- Flow distribution becomes uneven
- Controls get bypassed
- New lines get added without system redesign
- Cooling loads increase but infrastructure stays the same
Why These Issues Are Common in UK Manufacturing
Most legacy cooling systems were never designed for how the site operates today. They have typically evolved through:
- Incremental upgrades
- Production expansion
- Emergency repairs
- Piecemeal tower replacements
- Undocumented pipework changes
- "temporary” fixes that became permanent
Over time, the cooling system becomes a patchwork of disconnected assets rather than an engineered system.
The Six Most Common Cooling System Problems We Solve
1.
Poor Water Distribution
Uneven flow across heat loads leads to wasted pumping energy, unstable temperatures, and chronic underperformance.
Symptoms
- Hot spots on process equipment
- High pump energy use
- Inconsistent process temperatures
- Operators “fighting the system”
2.
Minimal or No Control
Many cooling systems operate with little automation, limited instrumentation, and no meaningful optimisation strategy.
Symptoms
- Pumps and fans running continuously
- Manual valve adjustments
- Inconsistent temperature control
- Energy waste hidden in plain sight
3.
Lack of System Knowledge
Most sites cannot confidently answer: “What is our cooling system designed to do?” No design basis = no control over cost or risk.
Symptoms
- No drawings or outdated schematics
- Unknown spare capacity
- Unclear resilience
- Decisions based on assumptions
4.
Capacity Constraints
Cooling capacity limitations often become hidden constraints on throughput and productivity.
Symptoms
- Summer instability
- Inability to expand production
- Repeated alarms or process trips
- Cooling “bottlenecking” output
5.
Disparate Cooling Systems (Not Centralised)
Many sites operate multiple disconnected cooling loops, towers, pumps and chillers - often with no coordination.
Symptoms
- Duplicated energy use
- Multiple small systems operating inefficiently
- Inconsistent performance across buildings/lines
- Maintenance burden multiplied
6.
Lack of Resilience
Legacy cooling systems often contain single points of failure that create unacceptable operational risk.
Symptoms
- No duty/standby capability
- Ageing assets with no redundancy
- Emergency repairs becoming routine
- Production vulnerability during breakdowns
WHAT THESE PROBLEMS COST
The Cost Is Rarely Visible - But It’s Always Real. Cooling system inefficiency doesn’t appear as a single line item.
For large manufacturing sites, these inefficiencies can quietly erode margin year after year. That’s why we position cooling optimisation as a commercial advantage - not a technical upgrade
HOW VISTECH SOLVES THEM
We Solve Cooling Problems End-to-End - Not Piecemeal Many suppliers fix individual components.
Vistech fixes systems.
We work from the process backwards to establish:
- Design basis and duty requirement
- System architecture and distribution strategy
- Control approach and operating modes
- Resilience requirements
- Mechanical, civil, electrical and automation scope
This allows us to define solutions that are:
- Measurable
- Commercially justified
- Deliverable without production disruption
How to Start the Conversation
Most clients begin with a Cooling System Efficiency Review.
Every engagement begins with a site visit. We see the system, speak to your team, and give you a clear picture before any commitment is made.
