RefriTech ProEvery feature earns its place in the engine room.
Every feature in RefriTech Pro is designed for industrial refrigeration professionals working in cold storage, food processing, and distribution facilities — and every one of them keeps working with zero bars of signal.
N°001Diagnostic engine
Diagnose
280 symptoms. 1,791 ranked causes. Zero guesswork.
The core of RefriTech Pro. A comprehensive, probability-ranked diagnostic database covering every major subsystem in industrial ammonia, CO2, and low-GWP refrigerant plants.
- 16 diagnostic systems covering compressors, condensers, evaporators, expansion/liquid feed, vessels, controls, leak detection, oil systems, glycol, CO2, piping, purgers, load validation, emergency systems, and electrical/VFD faults
- 280 symptoms with severity ratings to prioritize your investigation
- 1,791 probability-ranked causes with step-by-step diagnostic procedures
- Industry synonym search: "back pressure valve", "KVQ", "EPR", and "evaporator regulator" all return the same result
- Favorites and recents for quick access to frequently used diagnostics
- Equipment-type filtering: reciprocating, screw, rotary vane compressors; evaporative, air-cooled, shell-and-tube condensers; and more
N°002Checklists · Photos · PDF
Document
One session, 35 evaporators, a finished report before you leave the lot.
Multi-equipment checklists
Select multiple pieces of equipment and complete one comprehensive checklist session. Designed for technicians inspecting 20-35 evaporators or other repetitive equipment checks.
- Select up to 35 units per checklist session
- Five item types: checkbox (pass/fail), reading (numeric with units and min/max ranges), yes/no, photo capture, and text notes
- System-provided templates for common inspections plus custom templates for Enterprise users
- Section-based organization for logical grouping of checklist items
- Timestamps use device time — the recorded time reflects when the check was actually performed, not when it synced
PDF reports
Generate professional, branded PDF reports directly on-device. Share completed checklists with facility managers, engineers, and regulatory inspectors.
- Branded PDF export with company logo and facility information
- Toggle to include or exclude photos — keep file sizes manageable for email
- Per-equipment sections so each unit's results appear organized and clearly labeled
- Summary page with pass/fail counts, out-of-range readings, and flagged items
- Generated on-device — no network connection required to create the report
Photo documentation
Capture and attach photos to diagnostic logs, checklist items, and maintenance entries. Visual documentation is essential for warranty claims, insurance, and regulatory compliance.
- Camera capture directly within the app or select from device gallery
- Automatic compression before storage — no full-resolution images consuming storage and bandwidth
- Thumbnail viewer with pinch-to-zoom for reviewing captured photos
- Photos embedded in PDF reports when the include photos toggle is enabled
- Queued for S3 upload when connectivity is restored — photos are never lost
Voice notes
Dictate notes instead of typing. Essential when wearing gloves in a cold storage environment or when hands are dirty from working on equipment.
- Speech-to-text on all notes fields throughout the app
- Works with gloves — no need to remove PPE to type on a small keyboard
- Available on diagnostic logs, checklist text fields, and maintenance entries
- Transcription happens on-device for privacy and offline capability
N°003Refrigerant tools
Calculate
Field-accurate PSIG numbers for the four refrigerants that matter.
Essential calculation tools for field technicians. Accurate data for four refrigerants with proper PSIG pressure units used in the field.
- Pressure-Temperature (P-T) calculator displaying correct PSIG values for field gauge readings
- Superheat calculator: compare actual suction temperature to saturated suction temperature to verify proper evaporator feed
- Subcooling calculator: compare saturated discharge temperature to actual liquid line temperature to verify condenser performance
- Four refrigerants: R-717 (ammonia), R-744 (CO2), R-404A, and R-454B (low-GWP replacement)
- All calculations work offline with data bundled on-device
N°004Clients · Valves · Offline
Manage
Pick the client once — every log, valve, and serial number scopes itself.
Client management
Company-first architecture. Select your active client and all data automatically scopes to that facility. Manage multiple sites with separate equipment, logs, and history.
- Facility profiles with company name, address, contact information, and job numbers
- Equipment register: tag numbers, manufacturers, serial numbers, capacity, refrigerant type, and location within the facility
- Per-client diagnostic history showing all past investigations at each site
- Per-client maintenance logs filterable by PM, repair, emergency, and inspection
- Switch clients instantly and the entire app context updates
Relief-valve tracking
IIAR and ASME standards require relief valve replacement on a 5-year cycle. RefriTech Pro tracks every PRV across all your client sites with a clear, color-coded dashboard.
- 5-year replacement cycle tracking per IIAR/ASME standards
- Four-tier status system: Good (more than 12 months remaining), Plan (6-12 months), Schedule (less than 6 months), Expired (past due)
- Dashboard view showing all PRVs across a facility with color-coded status
- Set date, tag number, location, and notes for each relief valve
- Alerts when valves approach expiration so you can plan replacements during scheduled outages
Offline mode & security
Built for environments with zero cell signal. The entire diagnostic database, P-T tables, and safety references ship with the app. Security features protect sensitive client data.
- WatermelonDB (SQLite) local database for full offline operation
- Sync queue: all writes work offline and automatically sync when connectivity is restored
- Idempotent sync operations — retries never create duplicate records
- Encrypted local database for diagnostic and client data
- Screenshot prevention on screens containing sensitive client information
- Certificate pinning for API communication
- Authentication tokens stored in device secure keychain, never in plain storage
N°005Enterprise
Integrate
Your crew, your clients, your data — connected.
Team management
Enterprise adds multi-user team management for contractors running whole crews across shared client sites.
- Invite technicians by email and assign roles
- Role-based access control enforced server-side
- Shared client sites and equipment registers across the organization
- Each technician works independently offline and syncs to the shared account
Custom checklist templates
Build inspection templates that match how your shop actually works, then roll them out to the whole team.
- Section-based template editor with all five item types
- Clone and adapt system-provided templates
- Reading items with units and min/max ranges for out-of-range flagging
REST API & webhooks
Pull your service data into the systems you already run — CMMS, dashboards, or billing.
- Scoped API keys with per-key rate limiting
- REST endpoints for clients, equipment, and service history
- HMAC-signed webhook events for real-time integration
- Keys and webhooks managed by admins directly in the app
