What we have written on the cold chain154 / 154

Hold time depends on starting conditions, plate layout, fill and openings. Measure your acceptance curve on the longest route.

Verify model and serial, inspect the closure surfaces, then test with a representative load on route. Record defects before judging cosmetic marks.

Use your own route, maintenance and idle-time records instead of guessed utilisation. A mixed model can also cover seasonal peaks.

A model name alone does not produce a useful price. Put nine inputs on one form and competing quotes become genuinely comparable.
