Skid-mounted plant

Skid-mounted plant, pre-assembled and tested offsite

Pump sets, heat exchangers, pressurisation and boiler skids on a steel base, for refurbishments, upgrades and plant rooms inside existing buildings.

Overview

Plant on a frame, ready to connect

A skid carries the plant, pipework and controls on a fabricated steel base with lifting points and forklift pockets. It is sized for the access route into the building and connected at defined flanged break points.

Skids suit plant room refurbishment, boiler replacement inside existing boiler houses and data halls, where an external enclosure is not needed.

Types

Skids we build

Pump skids

Duty and standby pump sets with inverters, isolation, strainers and gauges.

Heat exchanger skids

Plate heat exchangers for hydraulic separation, heat network connections and free cooling.

Boiler skids

Boiler cascades on a common frame with header, pumps and flue connections.

Pressurisation and treatment

Pressurisation units, expansion vessels, degassers, dosing pots and side-stream filtration.

Benefits

Why skids work in occupied buildings

  • Less welding and hot works on site
  • Shorter shutdowns for plant changeover
  • Factory pressure testing before delivery
  • Consistent layout across multiple sites or phases
  • Accurate drawings for maintenance teams

Questions

What is a skid-mounted plant module?

An open steel frame carrying pre-assembled plant: pumps, heat exchangers, pressurisation, valves, pipework and controls. It is installed inside an existing plant room or building and connected at flanged break points.

Why choose a skid over site-built pipework?

Most of the fabrication, welding and testing moves to the workshop, so site time, hot works and disruption in occupied buildings drop sharply. Quality is more consistent and the skid arrives tested.

Will a skid fit through our existing access?

We survey door widths, corridors, lift capacities and headroom first. Skids can be split into sections with bolted joints to suit the route.
