Deployr

Trade operations platform

Go to deployr.tech

Run the whole trade business from one platform.

Deployr brings service calls, preventive maintenance, projects, quoting, purchasing, invoicing and trade compliance into a single system, from the office to the van to the customer’s inbox. Switch on the trade packs you work in and the app follows.

Trade packs, not separate products.

Jobs, scheduling, quoting, purchasing and invoicing work the same for every trade. Enable a pack and its assets, compliance registers, licence types and KPIs appear. Leave it off and you never see it.

One core system, with each trade switched on as a pack.

  • Electrical

    • Switchboards and circuits
    • RCD testing
    • Test and tag
    • Certificates of compliance
  • Plumbing & gas

    • Backflow devices
    • Thermostatic mixing valves
    • Hot water plant
    • Gas compliance
  • HVACR

    • Plant and refrigeration assets
    • Refrigerant cylinders
    • Gas transactions
    • Leak records
  • More trades

    • New trades add their own assets, registers and certificates

From the first call to the paid invoice, in one system.

Kelvin

HVAC/R engineering platform

Go to kelvin.engineering

From first principles to issued documentation.

The complete HVAC/R engineering workspace. Model refrigeration cycles, size piping, select equipment, analyse energy and cost, calculate charge and issue professional PDF reports, with a REST API that plugs straight into your job management workflow.

Design once; every later stage updates with it.

One continuous engineering thread.

Every module links back to the system design. Change a condition and the downstream piping, selections and analyses follow.

  1. Configure the cycle

    Pick a refrigerant, set temperatures and loads, get instant thermodynamic results.

  2. Lay out the piping

    Draw the floor plan and let every line size itself against velocity and ΔP limits.

  3. Select equipment

    Match compressors, condensers, coils and ancillaries from real catalogues.

  4. Analyse & cost

    Model annual energy, refrigerant charge and full project cost.

  5. Issue reports

    Generate branded PDF documentation, singly or as a project bundle.

Everything in one design suite.

From refrigerant selection through to charge calculation, costing and reporting: a complete workflow for refrigeration engineers.

Refrigerants, cycles, piping, equipment, energy, charge, cost and reports.

Deployr and Kelvin hand work to each other.

Kelvin integrates natively with Deployr. Engineering requests raised on a job arrive with their context, and the finished engineering goes back to the job it came from. No re-keying in either direction.

Deployr

Quotes, jobs, projects, assets and sites

Request

An engineering request raised against a quote, job, asset or site lands in Kelvin’s Engineering Inbox, complete with site data, equipment history and photos.

Return

Equipment schedules, documents and the full engineering package are pushed back to the originating quote or job.

Kelvin

Engineering Inbox, designs and reports

Other trades connect the same way.

Kelvin is the calculation engine for Deployr’s HVACR pack. Deployr’s Design & Calcs workflow is built so electrical and hydraulic engines can plug in through the same path.

API-first, both sides.

  • Versioned REST APIs
  • Organisation keys with read/write scopes
  • Signed webhooks for real-time sync

Built in Australia, for the trades.

Sentoro Technologies Pty Ltd is an Australian software company. We build Deployr and Kelvin, and the connection between them, so the people who design, install and maintain buildings can work from one job record.

Deployr and Kelvin are products of Sentoro Technologies Pty Ltd

  • Built around the trade.

    Each trade sees its own assets, registers and licence types, and nothing it doesn't need.

  • Field-first.

    Minimal taps per task, and job packs that keep working offline on site.

  • Engineering on the job record.

    Design work lands where the job lives, not in an email attachment.

  • Made for Australian contractors.

    GST, ABN and licence ready from day one.
