Home/Products/Turnkey cold rooms

Turnkey cold rooms, from drawing to commissioning

One contract covers design, manufacture, installation and commissioning. The reason to buy it that way is not convenience: a room only performs when the envelope, the units and the control are matched, and matching them is somebody's job.

Five stages, each with a defined deliverable

The stage boundary is where most projects lose time, so each stage states what is handed over.

  1. Room schedule and selectionProduct, room temperatures, tonnage and daily throughput are converted into a room schedule and a system selection.
  2. Design and drawingsPanel layout, unit positions, piping routes, electrical requirements and the interface schedule for the local scope.
  3. ManufacturePanels, units, coolers, condensers and control built at Qihe; each unit pressure-tested and run-tested before dispatch.
  4. InstallationEnvelope assembly, unit setting, piping and electrical by a local crew, under our technical supervision where required.
  5. Commissioning and handoverPull-down to temperature, defrost verification, alarm testing, operator training and as-built documentation.

Turnkey questions

How long does a project take?
Six to twelve weeks for a medium plant, depending on panel scheduling, equipment lead time and site conditions. Export projects add shipping and crew travel.
Who installs it abroad?
A local crew, with our engineers supervising under a business visa. Long-term site labour follows a different legal route, so the model is supervision and training rather than a resident team.
What if the room does not reach temperature?
Under a turnkey contract that is a single-party responsibility. The envelope, the units and the control are ours, so the diagnosis does not start with three suppliers disputing scope.

Product, room temperature, tonnage and daily throughput — enough to come back with a selection and an indicative price.
