Problems We Fix

Lack of System Knowledge

If your cooling system relies on tribal knowledge, it isn’t engineered, it’s inherited.

Many legacy cooling systems operate successfully for years, not because they are understood, but because a small number of people know how to ‘make it work’.

When that knowledge disappears, risk increases fast.

Vistech helps manufacturers rebuild system knowledge through design basis development, engineering definition, and clear operating strategy.

If Your Cooling System Lives in Someone’s Head, It’s a Business Risk

On many sites, cooling system knowledge is not documented. It exists as habit, workarounds, ‘how we’ve always done it’, and unspoken rules.

The system may be stable, but it’s often only stable because experienced operators know which levers to pull.

The result is a cooling system run by folklore rather than engineering.

The Most Common Control Philosophy in UK Manufacturing:

‘Bob said to always open that valve first.’

If your site relies on statements like:

  • Don’t touch that pump, it trips the system.
  • We always run both towers in summer.
  • That valve has to stay cracked open.
  • The BMS doesn’t really work, so we do it manually.
  • We don’t know why it’s like that, but it works.
Then you don’t have a cooling system strategy. You have a cooling system tradition.

Lack of Knowledge Drives Cost and Creates Risk

When a system isn’t understood, the business typically suffers through:

excessive energy consumption hidden as “normal”
over-pumping and over-cooling to avoid failure
inability to confidently identify savings
inability to justify investment or upgrade decisions
reactive maintenance and repeated breakdowns
higher downtime exposure due to unknown failure points
high dependency on a small number of individuals

For CFOs and operations leaders, this becomes a risk and margin problem, not an engineering problem.

Common Signs Your Cooling System Knowledge Is Missing

You may have a system knowledge problem if:

  • No one can clearly explain what the system is designed to deliver
  • Drawings are missing, outdated, or not trusted
  • Flow rates are unknown or assumed
  • Temperature strategy is unclear or inconsistent
  • Setpoints exist “because they always have”
  • Operators intervene manually to keep stability
  • Nobody can confirm spare capacity
  • Expansion projects trigger panic or guesswork
  • There is no documented operating philosophy
  • Critical risk points are not clearly defined

Why Cooling System Knowledge Disappears Over Time

This is common in legacy UK manufacturing because cooling systems evolve through:

Emergency Repairs

Emergency repairs and incremental plant additions without documentation

Supplier-Led Upgrades

Supplier-driven upgrades and undocumented modifications

Site Expansion

Site expansion without system redesign

Temporary Fixes

‘Temporary fixes’ that become permanent

Over time, the original design intent disappears. The system becomes a patchwork of assets that still functions, but no longer has a clear design basis.

How Vistech Restores System Knowledge

We rebuild clarity using engineering definition.

  • establishing the true process demand and cooling duty
  • mapping system architecture and interdependencies
  • identifying key performance limitations and failure points
  • defining operating modes (summer/winter/peak load/part load)
  • creating a design basis and functional description
  • identifying instrumentation gaps
  • defining mechanical, civil, electrical and controls scope
  • producing clear outputs that enable decision-making

This gives the site a documented cooling strategy that is not dependent on individuals.

The Outputs That Matter

The objective is not paperwork. The objective is clarity. Typical outputs include:

design basis and duty definition
system architecture diagrams and simplified schematics
operating philosophy and control strategy definition
prioritised improvement roadmap
commercial opportunity estimate (energy/water savings)
defined next-step recommendation

If You Can’t Describe the System, You Can’t Optimise It

Many manufacturers struggle to justify investment because they cannot confidently answer: what is the system currently consuming? What is it delivering? What is the real bottleneck? What is the cost of inefficiency? What is the cost of failure?

System knowledge is the foundation of ROI. Without it, savings are always assumed rather than proven.

How to Start

Most clients begin with a structured Efficiency Review.

When a FEED Study Is Required

Where system knowledge gaps are significant, and the site needs defined scope to support investment decisions, we progress to a FEED study.

FEED Study

FEED delivers: defined engineering scope, phased delivery plan, commercial payback model, board-ready capex justification.

This removes assumption and protects production planning.

Is Your Cooling System Running on ‘Tribal Knowledge’?

If your cooling system depends on habits, undocumented workarounds, or one key individual, it’s exposing the business to unnecessary cost and risk.

We can help define the system properly and identify measurable improvement opportunities.
