Why unit fuel per kilometre varies so much from route to route, how to work out fuel from unit hours, and which records that takes.

Compare rental, an alternate route or insulated containers against the same conditions. Verify product suitability and actual service time in records.

Do not blame the compressor alone. Compare kWh use with door, product-in and defrost records.

Compare full-pack cost and measured temperature profile for the same load and route.

Divide the invoice by kilograms weighed before use, not by quoted unit price. Compare delivery, return and packaging on the same basis.

Power access, costs and product disposition may be unclear during a hold. Keep a timeline and confirm roles in writing.

The dry ice you need is the container's hourly consumption multiplied by the worst-case hours of the trip. Hourly consumption is found once by weighing, and it grows with surface area, not volume, as the container gets bigger.

Do not attribute a bill change directly to a seal. Check contact, then compare meter data under similar conditions.

Icing is a trace of moisture from outside, not a fault. Once you work out how much water each kilogram of incoming air carries, the amount and the place of the ice can be measured.

Communiqué 2026/9 of Turkey's rural development investment programme funds cold stores at 50-70% of the eligible project amount including VAT. Rates, timetable, guarantee and purchasing rules in one place.

An EPS box has no fixed number of uses; the test is whether it can be cleaned and is dry on every return. How moisture changes insulation, what sets the life of a box, and how to measure the real number of trips.

The profit of a cold store investment comes down to two numbers: monthly occupancy and cost per pallet-day. A worked example shows how to calculate both and set them against a rental quote.

Consumption comes from heat load: wall transfer, product, doors, internal loads and defrost are added up and divided by the refrigeration efficiency (COP). Step by step with a worked example.

Litres are the inner volume; the choice runs from outside in. First a base that fits the 1200 x 800 mm Euro pallet layer, then wall thickness and the litres that remain.

A worked example shows how to read a price per square metre through its denominator, external surface and panel thickness.

Payback omits timing and later years. Use the same assumptions for present value and a sensitivity check.
