Used by reefer workshops, depot operators, shipping lines, and leasing companies across Europe, Africa, Australia and the Middle East — from single-depot operators to terminal operators processing tens of thousands of records monthly.
Reefer PTI and repair carry the highest financial and audit exposure of any container documentation work. A single missing compressor test, an undocumented electrical check, or an unverifiable PTI result can delay container release, sink an off-hire claim, or reject an AEMS submission — at exactly the point when speed matters most. The reefer record turns inspection into a container-linked technical file (photo, video, and audio) defensible under leasing-company audit and shipping-line claim review.
Container-linked technical evidence for reefer PTI, refrigeration unit repair, and pre-trip verification — replacing informal photo threads with a structured record (photo, video, audio) tied to the ISO 6346-validated container number, retained on terms the facility controls, and routed automatically to AEMS and carrier repair systems.

Where Reefer Documentation Quietly Costs Real Money
Reefer PTI and repair documentation is technical compliance evidence, not administrative paperwork. Compressor functionality, electrical test results, temperature unit condition, and alarm states have to be captured cleanly, retained, and produced on demand. When that evidence is missing, incomplete, or unverifiable, the cost shows up as rejected claims, off-hire disputes that slip away, AEMS submissions that fail, and leasing-company audits that surface reconstruction work nobody planned capacity for. A disputed reefer charge without defensible evidence becomes a direct operational cost.
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

Historical PTI records unrecoverable under time pressure from shipping lines
High-value operations — reefer PTI, carrier M&R, premium leasing — usually justify the business case regardless of inspection volume, because a single missing photo can cost more than a year of subscription. Structured reefer evidence turns "did the technician document it?" into "was the record produced and routed?" — taking documentation quality off individual diligence and onto a measurable process.

A Container-Linked Reefer Evidence Workflow — From Field to AEMS
ConPDS Checker turns reefer PTI/repair into a container-linked technical evidence record built for workshop and yard conditions — captured (photo, video, audio), validated against the ISO 6346 container number, retained under your retention rules, and routed automatically to AEMS and carrier M&R.

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 that container's verified 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 standard check-digit validation (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
Records are 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 operational evidence layer your current stack is missing.

Beyond Photos — Capture What Only Video and Audio Can Show
In reefer inspections, the decisive evidence is often motion and sound — a compressor vibration, a fan running unevenly, an alarm display cycling through fault codes. ConPDS Checker captures short video clips and audio recordings as container-linked evidence on the same audit log as the photos.

Why Reefer Documentation Has to Be an Evidence Layer
Standard container inspections document condition and damage. Reefer inspections have to document technical system function — compressor operation, electrical integrity, alarm states, and temperature control compliance — in a record that is verifiable, container-indexed, retained on terms the facility controls, and defensible under leasing-company and shipping-line audit.

Defensible Evidence for Agents, Shipping Lines, and Lessors
Reefer inspections have to be shared quickly with agents, shipping lines, and leasing companies in a format they can act on. The evidence workflow replaces informal photo sharing with consistent, ISO 6346-validated container records — immediately retrievable, container-indexed, and defensible under audit. For depot gate-in and lease return documentation, see how the container depot inspection evidence layer applies the same workflow to depot operations.

Frequently Asked Questions About the Reefer Evidence Layer
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.
Which systems does ConPDS Checker integrate with?
▼
ConPDS Checker integrates with Maersk AEMS Container Maintenance & Repair APIs, EOS, DepotMaster, CMA-CGM, IMARS, MSC OVMR, Hapag FIS, Saeco, Triton, and custom APIs via REST, FTP, SFTP, and email. If your system is not yet supported, we will add the integration on request. Documentation is pushed directly to your reefer management or M&R system — eliminating manual upload and documentation gaps between field capture and system record.
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.

Make Reefer PTI & Repair Evidence Defensible by Default
If your facility runs reefer PTI, refrigeration unit repair, and leasing-company documentation requests every day, the question is not whether you have technical evidence — it is whether you can produce it on demand for the lessor audit, the AEMS submission, and the off-hire claim. ConPDS takes that off individual diligence and onto a measurable process.
A Disputed Reefer Charge Without Defensible Evidence Becomes Direct Operational Cost
✗ Claim rejected: A leasing company denies a spare-part warranty claim because no evidence links the replaced component to the validated container number or the specific PTI event.
✗ Release delayed: A container is held at the terminal because the unit's PTI result cannot be verified — the evidence was captured but cannot be attributed to the correct unit.
✗ Liability exposed: An electrical fault dispute cannot be resolved because the compressor and fault-code evidence from the last inspection lives only in a personal chat thread that has since been cleared.
✗ AEMS submission fails: A shipping line requests verifiable PTI evidence via AEMS and the facility cannot produce a container-linked record — the submission is incomplete and requires manual resolution.
✗ Audit gap surfaced: A leasing-company audit reveals PTI records spread across personal devices with no central archive, no GPS metadata, and no distribution log — a compliance exposure that cannot be corrected retroactively.
