What does a buyer check before specifying refrigeration equipment?
They check cooling capacity at their actual evaporating and ambient conditions, the refrigerant and its regulatory position, and the energy performance. Refrigerant choice now carries regulatory risk over the asset's life, so it is a first-order question rather than a technical detail.
A cold store operator is investing in equipment that must still be legal and serviceable in fifteen years.

Scope and specifications
- Equipment type and application
- Chillers, condensing units, cold rooms and transport refrigeration differ entirely.
- Cooling capacity at stated conditions
- Capacity without evaporating and ambient conditions is not comparable.
- Refrigerant and its regulatory position
- Phase-down schedules affect the asset over its life.
- Energy performance ratio
- Refrigeration runs continuously, so energy dominates cost.
- Temperature range
- Chilled, frozen and blast applications are different machines.
- Ambient design conditions
- Performance in hot climates diverges sharply from rated figures.
- Control and monitoring capability
- Determines what can be evidenced for food safety.

Questions suppliers ask
How should refrigerant choice be presented?
Openly, with the global warming potential and the regulatory position stated. Buyers are making a fifteen-year decision under a changing regime, and a supplier who explains the trade-offs honestly is trusted more than one who quietly offers the cheapest available refrigerant.
Why publish capacity across conditions?
Because the rated condition rarely matches the installation. Publishing a capacity table lets a buyer see performance at their own ambient and evaporating temperatures, which is both more honest and more useful than a single flattering figure.
What matters most to a cold chain operator?
Uptime and evidence. Equipment that fails spoils stock, and food safety records require temperature data. Service response times, monitoring capability and reporting are frequently more decisive than efficiency, and they are rarely presented well.
