Chiller solutions for large buildings and facilities
A chiller plant includes more than the main machine. Pumps, valves, strainers, expansion provisions, air separation, chilled-water piping, air-handling units, controls, insulation and balancing all affect the final performance.
We assess the operating condition and network before recommending repair, replacement or modification. The scope may include lifting coordination, mechanical connections, supports, pressure testing, flushing, insulation, BMS interfaces and commissioning.

Service delivery stages
- Existing-system assessmentInspect the chiller, network, pumps and controls and identify the real constraint.
- Replacement or repair planDefine equipment, valves, connections, shutdown sequence and safety requirements.
- Installation and testingExecute piping, supports, pressure testing, flushing, insulation and connections.
- Commissioning and balancingStart pumps and chillers, adjust flows and document operating readings.
Evaluate the complete chilled-water system
Poor cooling may be caused by low flow, air in the network, fouled heat exchangers, valve issues or unsuitable pumps rather than the chiller alone. Decisions should be based on measured system conditions.
- Check supply and return temperature difference
- Verify pump duty, valve direction and strainers
- Inspect insulation, condensation and pipe supports
- Provide measuring, drain and vent points
Sectors we serve
Chillers are commonly evaluated for large or long-operating facilities that need centralized chilled-water distribution.

Frequently asked questions
When is chiller replacement better than repair?
The decision follows an assessment of compressors, heat exchangers, controls, spare-parts availability, energy use, repair cost, remaining life and current cooling demand.
Can the scope include pumps and valves?
Yes. The agreed scope may include pumps, isolation and balancing valves, strainers, air separators, expansion components, supports and insulation.
When is chemical cleaning required?
It may be considered when deposits, contamination or poor heat transfer are confirmed. The chemical and procedure must suit the piping and connected equipment.
Why is water balancing required after modifications?
Balancing verifies that each branch and terminal receives its required design flow and prevents excessive or insufficient flow that reduces performance.
Do you have an existing chiller or replacement project?
Send equipment data, drawings, photos and available readings to define the initial assessment scope.
