Project files · no names

Five files, written at industry level

Each file carries the same four elements, in the same order.

No customer name, no logo and no brand mark appears here or in any file.

01 / How to read a file

The key, and the rule

Situation · requirement · supplied · outcome

No customer name

Racks are counted, halls by area, operators by segment.

No name appears in a file, caption or image.

No logo, no brand mark

No logo rail, no client strip and no partner mark is published here.

The rule binds images and alt text.

Two numbers per file

One from the specification, one from the outcome.

Five files, the same order.

Anonymised reference files — inspection record, commissioning log, acceptance criteria — are available against a model code and loop description.

02 / File 01 · colocation

Situation	a 1,100 m² colocation hall converted to liquid cooling in phases, tenants live throughout
Requirement	locate a first drip inside a locked tenant rack, without a nuisance alarm
Supplied	190 m of EMS-LD-R500 rope on two controller channels · EMS-LD-C8 controllers · clips at roughly 1 m spacing
Outcome	first leak located at 3.4 m along channel 2 on day 11, at 0.1 m position resolution against ±1.08 m locating repeatability at 190 m of cable · 2 nuisance alarms in 90 days, both from floor-sealing chemical

03 / File 02 · AI training hall

Situation	an AI training hall moving to 132 kW racks on a 4,800 L secondary loop, with commissioning debris reaching 100–400 µm microchannels
Requirement	hold suspended solids below 5 µm at the cold plate, and know when a cartridge is spent
Supplied	EMS-CF-S08 side-stream skid · EMS-CF-F1-10 and EMS-CF-F5-20 cartridges, coarse to fine · EMS-CF-FP-DP transmitters
Outcome	full loop turnover every 10 hours · first cartridge changed at 35 psid (2.4 bar), inside the 60 psid (4.1 bar) element maximum · under half the terminal value at day 90

Jumper bundle on a manifold

04 / File 03 · HPC

Situation	a mixed-generation HPC hall where nodes were swapped repeatedly and clamped jumpers weeped at the clamp band after a year
Requirement	a rack-interior jumper that survives repeated intervention in a 40 mm gap
Supplied	EMS-HP-J2-06-QD quick-disconnect bundles: EPDM −6 at 9.5–10.3 mm inside diameter, 37 mm bend radius, 4.0× burst margin, no clamp
Outcome	640 bundles over 14 months · clamp-band weeps in the following 12 months: 0 · 3 sleeve seizures, all after a coupling mated under pressure

Rack gap and routed radius

05 / File 04 · edge and telecom

Situation	46 unmanned outdoor cabinets on glycol loops, with no technician inside 90 minutes
Requirement	an alarm that reaches the building management system over Modbus RTU with the zone named, no trip on condensation
Supplied	EMS-LD-P2 point probes set 3 mm above the cabinet floor · EMS-LD-C2 zone controllers · leak setpoint 150 µA for 20 s, contamination setpoint 50 µA for 120 s
Outcome	11 alarms in 12 months, 9 confirmed coolant and 2 condensation that did not repeat · scheduled site visits fell from a monthly round to 3 in the year

06 / File 05 · burn-in floor

Situation	a burn-in floor replacing thermal grease on accelerator modules every quarter because the paste pumped out of a 0.05 mm bond line
Requirement	hold interface resistance across thermal cycling at the same pressure
Supplied	EMS-TM-PC85 phase-change sheet: 45–55 °C transition, 0.20–1.0 mm, ≤0.0078 °C·cm²/W by ASTM D5470, UL 94 V-0
Outcome	rework interval moved from 90 days to beyond 12 months on 220 modules · joint impedance within 0.002 °C·cm²/W of the as-built value after 500 cycles

Impedance against cycles
