Trusted by container depots, shipping lines, and leasing companies across Europe — from single-depot operators to large-scale terminal operators processing tens of thousands of photos monthly.
Reefer repair and pre-trip inspection (PTI) documentation carries significantly higher operational and financial risk than standard container inspections. Missing compressor test evidence, undocumented electrical checks, or unverified PTI results can delay container release, complicate claims, or expose facilities to unnecessary liability. CONPDS Checker provides structured, verifiable technical evidence for refrigerated container inspections and refrigerated container repair documentation — not just photos.
Structured mobile documentation for refrigerated container inspections, PTI verification, and reefer repair workflows — replacing informal photo threads with searchable, container-linked evidence that holds up to shipping line and leasing company scrutiny.

Reefer PTI Documentation Gaps Create Real Financial and Operational Risk
Reefer repair and pre-trip inspection documentation is not just an administrative task — it is technical compliance evidence. Compressor functionality, electrical test results, temperature unit condition, and alarm states must be documented clearly and shared quickly. When that evidence is missing, incomplete, or unverifiable, facilities face claim rejections, delayed container releases, and avoidable liability exposure.
In many reefer facilities, PTI and repair records are still
Captured on personal devices with no container-number link or PTI reference
Shared via WhatsApp or email — stored in chat threads, not inspection records
Filed without consistent structure — no link to compressor checks, alarm codes, or electrical test results
Difficult to retrieve when an agent, leasing company, or shipping line requests verifiable PTI history
Not connected to AEMS or reefer M&R systems — documentation and operational records stay separate

Historical PTI records unrecoverable under time pressure from shipping lines
Missing or incomplete PTI evidence can delay container release, block export scheduling, or trigger secondary inspection requests from shipping lines — at exactly the point when speed matters most. In reefer operations, missing or misplaced PTI and repair documentation can also complicate leasing company claims and expose facilities to disputes that are difficult to defend without structured evidence. A refrigeration container documentation system designed for technical compliance removes that risk at the source.

A Structured Reefer Inspection Workflow — From Field to Dashboard
CONPDS Checker replaces informal photo handling with a structured reefer PTI documentation platform built specifically for workshop and yard conditions — from field capture to web dashboard to AEMS integration.

Step 01 — Capture
Capture PTI, Repair, and Technical Inspection Evidence in the Workshop or Yard
Technicians use the CONPDS Checker mobile app on their existing smartphones or tablets to capture structured evidence during pre-trip inspections, electrical checks, unit damage assessments, structural repairs, and refrigeration unit repairs. No additional equipment required.
In reefer environments, motion and sound matter. CONPDS Checker supports short video clips (up to 30 seconds) and audio recording — allowing technicians to document compressor noise, fan movement, alarm display states, and PTI test results as structured multimedia evidence linked directly to the validated container record. This level of technical evidence is not possible with static photos alone.
Step 02 — Validate
Automatic Container Number Recognition with ISO 6346 Validation
The system reads and validates the container number directly in the app using AI-powered OCR with ISO 6346 standards (owner code, serial number, and check digit validation) — ensuring every PTI photo, repair image, and spare part record is always linked to the correct container. Photos are stored under the validated container reference immediately, eliminating manual renaming, reducing documentation errors, and creating a clean inspection record from the first capture.
Step 03 — Store
A Permanent, Searchable Archive of Reefer Maintenance Photo Records
All PTI photos, repair records, spare part documentation, compressor test evidence, and inspection notes are stored in a searchable cloud archive — organised by container number. The complete refrigerated container inspection history builds automatically per container: pre-trip inspections, electrical checks, unit repairs, and post-repair validation, all retrievable in seconds — even months later during disputes or audits.
Step 04 — Share
Verifiable PTI Evidence for Agents, Shipping Lines, and Leasing Companies
Instead of forwarding informal photo threads, reefer facilities share structured inspection documentation packages directly from the web dashboard — logged and traceable. The system supports documentation requirements for leasing companies and shipping lines requesting verifiable PTI and repair evidence: structured records, timestamped captures, GPS-tagged locations, and a full audit trail of every distribution event. Every package sent is permanently logged per container.
Step 05 — Integrate
Integration With Reefer Management and AEMS Systems
Documentation can be pushed directly to your reefer management or M&R systems via API — eliminating manual upload, duplicate handling, and documentation gaps between field capture and system record. CONPDS Checker does not replace your existing system; it adds the structured photo evidence layer your current stack is missing.
Why Reefer Repair Documentation Requires a Structured Approach
Standard container inspections document condition and damage. Reefer inspections must document technical system function — compressor operation, electrical integrity, alarm states, and temperature control compliance. That evidence must be verifiable, container-indexed, and defensible under scrutiny from leasing companies and shipping lines.

Professional Documentation for Agents and Shipping Lines
Reefer inspections often require documentation shared quickly with agents or shipping lines — in a format they can act on. A structured reefer inspection workflow replaces informal photo sharing with consistent, ISO-validated container records that are immediately retrievable and defensible. For depot gate-in and lease return documentation, see how the container depot photo documentation software applies the same workflow to depot operations.
✗ Informal Photo Sharing
✗ Photos in personal chat threads — not against container or PTI records
✗ No container number link — retrieval depends on memory
✗ WhatsApp compression removes GPS and timestamp metadata
✗ No audit trail — no record of who received what or when
✗ Historical PTI records hard to recover under time pressure
✓ Structured Reefer Documentation with CONPDS
✓ All PTI and repair photos linked to ISO 6346-validated container records
✓ Searchable by container number, date, inspection type, or technician

Frequently Asked Questions About Reefer Repair Documentation
Can CONPDS Checker support PTI documentation?
▼
Yes. CONPDS Checker is well suited for capturing structured photo and multimedia documentation during pre-trip inspections. Photos, short video clips (up to 30 seconds), and audio notes are automatically linked to the validated container number using ISO 6346 standards — creating a complete, retrievable PTI record without manual renaming or sorting. Everything is searchable from the web dashboard immediately after capture.
Does CONPDS Checker integrate with Maersk AEMS?
▼
Yes. CONPDS Checker integrates with Maersk AEMS Container Maintenance & Repair APIs, as well as EOS, DepotMaster, and custom APIs. Documentation can be pushed directly to your reefer management or M&R system via API — eliminating manual upload, duplicate handling, and documentation gaps between field capture and system record. Your existing AEMS workflow remains unchanged.
Can technicians use their own devices?
▼
Yes. The app runs on standard iOS and Android smartphones and tablets already in use by technicians. No additional hardware, specialist devices, or equipment rollout is required. If your technicians can take a photo on a phone, they can use CONPDS Checker from day one — no manuals, no classroom training, no resistance from the team on the ground.
Does it work offline in workshop areas?
▼
Yes. CONPDS Checker works fully offline — AI-powered container number recognition, photo capture, video recording, and all core documentation functions run without a network connection. Data queues on-device and synchronises automatically once connectivity is restored, making it reliable in reefer workshops, container yards, and terminal areas with intermittent signal.
How quickly can a reefer facility start using the system?
▼
Most facilities are fully operational within hours of onboarding. Setup includes tenant configuration, user and role management, and standard forwarding and distribution rules — all handled by the ConPDS team. An initial onboarding call is included with every subscription. No on-premise infrastructure is required and no project management burden falls on your team. The core reefer PTI and repair photo documentation workflow can typically be running the same day.

Build a Defensible Record of Every Reefer Inspection
If your facility handles PTI inspections, refrigerated container repairs, and leasing company documentation requests, a structured pre-trip inspection documentation system ensures every technical check is captured, referenced against a validated ISO container record, and retrievable when it matters.
What Happens Without Structured Reefer PTI Documentation
✗ Claim rejected: A leasing company denies a spare part warranty claim because no photo evidence links the replaced component to the validated container record or the specific PTI event.
✗ Release delayed: A container is held at the terminal because the reefer unit's PTI result cannot be verified — the evidence was captured but cannot be located or attributed to the correct unit.
✗ Liability exposed: An electrical fault dispute cannot be resolved because the compressor and fault code documentation from the last inspection exists only in a personal chat thread that has since been cleared.
✗ AEMS submission fails: A shipping line requests verifiable PTI photo evidence via AEMS and the facility cannot provide a structured, container-indexed record — the submission is incomplete and requires manual resolution.
✗ Audit gap identified: A leasing company audit reveals that PTI records for multiple units are stored across individual technician devices with no central archive, no GPS metadata, and no distribution log — creating a compliance exposure that cannot be corrected retroactively.
