Reefer Guru

Refrigerated container technicians work against dense service literature, controller alarms, and strict safety rules — often in the yard, at night, under time pressure. Reefer Guru is a mobile-first AI assistant built to answer technical questions fast for people servicing Carrier Transicold refrigeration units.

Official manuals are the source of truth, but finding the right alarm cause, function code, torque value, or safety step mid-job is slow. Technicians needed a specialist tool — not a general chatbot — oriented to reefer work and yard conditions.

An expert-oriented diagnostic assistant with multimodal input (photos of controllers, plates, or components), structured technical lookup, session history on device, and a dark-mode UI suited to nighttime operations.

• ▹Guidance oriented to Carrier Transicold product families: PrimeLINE, ThinLINE, OptimaLINE, EliteLINE, and NaturaLINE
• ▹Alarm and function-code style troubleshooting support for Micro-Link controller families
• ▹Image upload for controller displays, serial plates, and visible component issues
• ▹Emphasis on safety-sensitive topics such as R-1234yf (A2L) and high-pressure CO₂ (NaturaLINE) practices
• ▹Local session history so ongoing repairs can continue across shifts on the same device
• ▹Responsive, mobile-first layout with dark mode for yard use

Knowledge is oriented around major Carrier Transicold container refrigeration lines and related software tooling (e.g. data and fleet software documentation). The public product does not redistribute full OEM manuals; it is an assistant for technicians who already work within official training and documentation.

Reefer Guru is a technical assistant — not a substitute for official training or the physical service manual. Technicians remain responsible for lockout/tagout, refrigerant-specific safety protocols, high-pressure warnings, and verifying critical values against the unit serial plate and current OEM documentation.
