Cold room project case study in Germany: CO₂ transcritical plant for a 2,200-pallet frozen DC, North Rhine-Westphalia
A new distribution centre where refrigerant policy, energy efficiency and heat recovery were board-level requirements rather than engineering preferences.
A 2,200-pallet −18 to −25 °c frozen facility in Germany of roughly 9,900 m³, built with co2 (r744) transcritical or cascade, models at about USD 13,331,908 installed (USD 10,665,527–USD 17,331,481 planning range) and USD 1,537,435 a year to run, over a 68-week programme from brief to handover. Figures are indicative planning estimates from ColdMatch Group's country cost model — not a quotation.

What was built, and for whom
Moderate humidity — standard defrost and condenser selection
~15 generator hours modelled per year
Local band 0.150–0.260 USD/kWh
Zones
- Frozen store −24 °C, 2,200 pallets with automated aisles
- Chilled picking area +2 °C
- Conditioned dock with air curtains
What a project like this costs in Germany
Derived from the same indicative country cost model used by the public ColdMatch calculators: local construction cost index, design ambient, humidity, grid reliability, diesel price and electricity tariff. Planning-grade estimates, never a quotation.

Running the same facility on legacy fixed-speed plant models at USD 1,951,131 a year — about USD 413,696 more, which is the efficiency decision this project turned on.
What made this project difficult in Germany
These are the local realities that change the design, the price and the supplier shortlist.
- Corporate refrigerant policy excludes high-GWP options
- High electricity price makes efficiency the dominant lifecycle factor
- Heat recovery expected to serve site heating
The decisions that shaped the result
- CO₂ transcritical with parallel compression and ejectors for the climate profile
- Full heat recovery into site heating and hot water
- Automation to reduce infiltration and labour in the frozen aisles
Programme: about 68 weeks from brief to handover
Phases overlap in practice. This sequence shows where the schedule risk sits in this market.
- 1
Brief and feasibility
Weeks 1–3 · 3 weeksProduct, temperature, capacity, site status, electrical supply, budget band and timeline confirmed. ColdMatch reviews the brief and flags missing data before anyone is approached.
- 2
Concept design and RFQ preparation
Weeks 4–7 · 4 weeksZone layout, load estimate, system shortlist and a single bid form so every supplier quotes identical scope, exclusions and assumptions.
- 3
Supplier review and tendering
Weeks 8–13 · 6 weeksSuitable suppliers are approached only after internal approval, then proposals are normalised on scope, energy assumptions, spares, commissioning and warranty.
- 4
Civil works and building envelope
Weeks 14–33 · 20 weeksSlab, drainage, docks and structure, including under-floor heating detail where freezer rooms sit on grade.
- 5
Equipment manufacture and delivery
Weeks 34–49 · 16 weeksPlant and panel manufacture with delivery sequenced to the installation programme.
- 6
Installation and insulation
Weeks 50–63 · 14 weeksPanel erection, pipework, electrical and automation installation with a written interface responsibility matrix between refrigeration and automation scopes.
- 7
Commissioning, pull-down and handover
Weeks 64–68 · 5 weeksLeak and pressure testing, staged pull-down, performance verification against the specified duty, operator training, spares handover and documentation.
What the project delivered
- Refrigerant policy satisfied with a future-proof system
- Site heating largely covered by recovered heat
- Lifecycle cost, not purchase price, used as the award criterion
What buyers in this market should take from it
- In high-tariff markets, award on modelled lifecycle cost with audited assumptions
- Heat recovery changes the business case — quantify it before comparing bids
