Liquid-cooled data centres · Defence

Clean loops.
Certified at handover.

A sealed cooling loop is filled once and runs for the life of the facility. We get it clean, fill it right, and hand over the measurements that prove it.

If compute is revenue, time to compute has economic value. If time to compute has value, certainty has a price. The flush is the last step before IT load goes on. A loop signed off dirty takes a hall offline on a date already sold to a tenant. We make certain it is clean, and we prove it.

Why SI

Built for the systems that cannot fail.

Owners and primes come to us because the handover is measured, the scope is single and the equipment is chosen for the loop.

01

One scope

Clean, fill, commission and certify from one contractor. No gap between trades, no second record.

02

Measured handover

Acceptance by instrument against agreed criteria. The certificate becomes the baseline you keep.

03

European equipment

Units, plant and fluids from selected European manufacturers, matched to the loop and its approvals.

04

Australian owned

Based in Western Sydney. Data centre and Defence work under one standard.

Global reach

Units, plant and fluids from selected European manufacturers, supplied across Australia and Asia-Pacific.

02

Local expertise

Sydney-based engineers and crews, on your programme and under your site rules.

03

Secure, compliant, sustainable

Security set at contract stage, compliance evidenced at handover, fewer chemicals and less water.

Working with us

How an engagement runs.

  1. 01Enquiry

    The loop, the date for IT load, and the specification you are working to.

  2. 02Site walk

    We see the loop, the access and the programme before we price it.

  3. 03Proposal

    One scope, one price, one programme. No separate flush and fill.

  4. 04Mobilise

    Our crew and our equipment, inducted and on your programme.

  5. 05Handover

    Certificate signed, loop sealed, baseline in your hands.

Talk to us early

Have a loop to commission?

Tell us the loop and the date. We come back within one business day.

  1. 01At design

    The commissioning scope is right before the specification goes out.

  2. 02In construction

    The flush and fill is programmed off the critical path.

  3. 03At handover

    One certificate. The baseline you keep.
