Diagnose Faster.
Repair Smarter.
Keep Cold Chains
Moving.
The professional web app for reefer technicians. Instant alarm codes, AI-powered troubleshooting, hands-free voice operation — for Carrier and Thermo King units. No download, no install — just open it.
Technicians deserve better tools.
We built them.
Cold-chain reliability is non-negotiable. Every minute of reefer downtime puts cargo at risk and costs money.
Today's Reality

Flipping through paper manuals in the field wastes critical repair time

The ROI is immediate.
The results speak for themselves.
Up to 70% Faster Diagnosis
What used to take 30 minutes of manual research now takes seconds. AI-powered fault-finding cuts diagnostic time dramatically.
Reduce Costly Downtime
Every hour a reefer is down risks cargo integrity and brand reputation. Faster diagnosis means faster repair and lower losses.
100% Offline Capable
Works without internet in depots, ports, and remote locations. All alarm codes and AI data are available even without a signal.
Built for Real Technicians
Designed with input from reefer specialists. Voice commands, clear typography, and a layout that works with gloves on in tight spaces.
Trusted by technicians
across the cold chain.
“I used to spend 30 minutes hunting through paper manuals for alarm codes. With Reefer Tech Pro, the AI tells me exactly what to check and in what order. It's like having a senior tech on call 24/7.”
“Our service team's average repair turnaround dropped by over 40% in the first month. The AI troubleshooting is genuinely impressive — it catches things we'd normally miss on first inspection.”
“The PDF report feature alone is worth the subscription. We used to spend hours writing up service sheets. Now it's done before the technician leaves the site. Game changer for our admin team.”
Licensed to your fleet.
Not to your techs.
ReeferTechPro is sold per fleet, not per technician. Your team gets the full diagnostic suite; access stays under your control.
Per-fleet licensing
One contract covers your whole team. Add or remove technicians anytime — access follows the fleet, not the individual.
Revoke when techs leave
When a technician moves on, you revoke their account in seconds. No risk of them keeping access on a personal device.
Custom-priced per seat
Small workshops to multi-depot operations. We quote based on team size and depot count — no public price list.
Fleet-wide history
Every job your team has logged, every refrigerant top-up, every alarm seen — all visible to fleet admins.
Manuals tuned to your fleet
We can integrate your unit-specific manuals so the AI Agent answers in your fleet’s context, not generic web data.
Hands-on onboarding
We set up your team, train your techs, and stay on call. No DIY signup flow — real humans answering email.
