Fleet and refrigeration units3 / 7

Your use calendar and quote set the decision point, not assumed day-count bands. Compare both options against the same routes and annual costs.

Include payload, refrigeration and stops in range planning. Compare manufacturer data with energy and charging records from your route.

With the engine running the alternator feeds the fridge; once it stops the load falls on the battery. A 100 Ah battery holds 1.2 kWh in total and a starter battery cannot be deep-cycled.

On a refrigerated vehicle the chassis, body and unit age separately. Tax depreciation is tabled at 5 years (20%) for a heavy truck and 4 years (25%) for a light one; real life and the replacement decision come from component records.

Do not measure a failure by the repair invoice alone. Collect order, rerouting, product-disposition and extra-trip records for each incident.

A service calendar follows more than running hours or a year. Track model, operating mode, environment, service records, consumables and backup in one budget.

Independent diesel refrigeration units burned roughly 1.8 to 2.3 litres an hour in tests. The share of a direct-drive unit cannot be found unless it is measured apart from the vehicle's consumption.

A unit sensor and a product measurement show different things. State which reading you took, where and by what method on the delivery record.

Do not judge urgent transport by invoice alone. Record extra labour, waiting and delivery effects, then compare with a permanent-capacity quote.

Do not call longer operation, icing or repeated excursions a failure by themselves; combine context, records and qualified technical review.

Do not guess the battery impact. Use the container model's manual and vehicle measurements to log load with the engine on and off.

Build a cost ledger for one period and service scope, then track investment allocation, energy sources and actual downtime separately.

Do not infer temperature risk from stop count alone. Record open duration, sensor traces and delivery sequence together.

Separate vehicle repair from load protection. The driver should record the breakdown, alarms and logger status, then follow the contact plan.

A refrigeration unit cooling the air does not show that product core is at target. Base the loading decision on product readings and shipment requirements.

Compare spare parts, containers or vehicles with failure and downtime records. Include idle time and maintenance cost.
