The platform
A controller on every unit, one console over all of them
CoolTech takes over the refrigeration cycle on the equipment you already own, then reports what it is doing to CoolTech Central — monitoring, alerting, compliance records, multi-site structure, access control and the whole lifecycle of the units underneath it.
Control
CoolTech is the controller, not a sensor on the wall
It fits the walk-ins, freezers, reach-ins and cases you already own and takes over the refrigeration cycle — compressor, defrost, fans. You keep your equipment; CoolTech becomes the brain running it, and every setting a technician would turn at the unit is settable from a browser.
Fits your existing equipment
You are not buying new coolers. CoolTech is wired into the refrigeration system you already run, by a technician, in a normal service visit.
Runs the refrigeration cycle
Compressor staging, defrost initiation and termination, fan behaviour and alarm limits are all decided by CoolTech at the unit — not reported on from the outside.
Setpoints from anywhere
Change a setpoint from the unit page or straight from the fleet list. Two setpoints with automatic time-of-day switching cover day and night targets.
Full defrost configuration
Defrost type and mode, defrosts per day, run time between, demand sensitivity, pump-down, termination temperature, drain time and maximum defrost length.
Alarm setpoints and delays
High and low alarm enable, offsets and delays configured per unit, so a blast chiller and a produce cooler are not held to the same rule.
Fan and coil behaviour
Fan state, delay temperature and delay time, coil release temperatures, air temperature differential, minimum compressor run and off times.
Queued changes stay visible
A change made while a unit is offline is shown as pending and applied on the next check-in, with confirmation when it lands. Nothing is silently lost.
Applied means applied
Every command is acknowledged as applied or failed. CoolTech never reports 'sent' and lets you assume 'done'.
Visibility
Every unit, every site, one screen
The fleet view is the whole estate at a glance — and it updates itself the moment something changes, so what you are looking at is what is happening.
Live fleet dashboard
Customer, unit, location, asset, return-air temperature, active setpoint, coil sensor readings and last-seen time for every unit you have access to.
Updates without refreshing
The screen changes when the equipment does. Nobody has to remember to reload, and nobody is looking at a five-minute-old number.
Search that matches how you think
Filter by customer, location, unit, asset, status, connection state, pending changes, or the current reading itself.
Temperature history charts
Any unit, any time range, custom date windows. The shape of a defrost cycle is obvious, and so is the shape of a failing one.
Technician diagnostics
Connection, sync, command and equipment health on one page — the screen you open before deciding whether to send a truck.
Wall display mode
A full-screen rotating readout of setpoint, return air, coil sensors, outputs and last defrost for a back-office monitor or a screen at the unit.
Alerting
Alerts people actually trust
An alert system only works if nobody has learned to ignore it. Every rule here is built to fire when it matters and stay quiet when it does not.
Sustained-breach thresholds
A reading has to be out of range and stay out of range for a duration you set. A delivery door held open does not page anyone.
Offline and stale detection
Alerts when a unit stops reporting, and separately when a unit is still connected but its readings have stopped moving — the failure mode most systems miss entirely.
Published detection times
Every alert type states its true worst-case detection time in the editor. You are never sold a fifteen-minute promise the system cannot keep.
Predictive equipment health
Degradation in the unit's own hardware — wear, media faults, cabling, response times — raises an alert before the failure, so replacement happens on a scheduled visit.
Email and text deliveryRolling out
Both channels, with retry. Phone numbers live on the person, so one number change updates every rule that reaches them.
Escalation chainsRolling out
Manager now, on-call phone at fifteen minutes, whole admin group at thirty. Acknowledging in the console stops the chain.
Business hours and rate limitsRolling out
Hold non-urgent texts to working hours; critical always breaks through. A per-number cap means a runaway condition pages once, never a hundred times.
Delivery receipts
Every send is recorded with recipient, time and outcome. An alert channel that quietly broke is visible instead of looking like a quiet week.
Records
The log is already written
Compliance stops being a task when the record is a byproduct of the equipment doing its job.
HACCP temperature reports
The food-safety temperature log an inspector asks for, over any date range, for one unit or a whole group.
Setpoint audit trail
Who changed which setpoint, when, and to what. The report that answers 'why was this cooler at 45 degrees'.
CSV export
Every report exports for spreadsheets, auditors, insurers and your own archive.
Scheduled delivery
Reports generated and emailed on a recurring schedule, with nobody responsible for remembering to run them.
Configuration history
A dated revision history for every unit, so a change three months ago is still explainable today.
Structure
Built for more than one building
Customers, locations and groups are first-class, which is why a service contractor can run an entire book of business from one login.
Separate customers
Full separation between customers. A service company runs every client from one login and no client ever sees another.
Locations with real timezones
Each site carries its own timezone, so overnight maintenance windows and daily reports read correctly where the equipment actually is.
Groups that cut across sites
'Every walk-in freezer', 'Stores 12 and 14' — group anything, then scope alerts, reports and permissions to the group.
Scoped access
Platform administrator, customer administrator and viewer roles, each seeing exactly the customers, groups and locations assigned to them.
Billable unit counts
Per-customer counts with explicit exclusions for demo, internal and warranty units, exportable for invoicing.
Security
Access you can account for
Refrigeration control is an operational capability. It is treated like one.
Two-factor authentication
Time-based two-factor enrolment for administrator accounts, with an administrator-side reset path.
Single sign-on
Sign in with existing Microsoft or Google work accounts alongside username and password.
Audit trail
A searchable record of administrative and security-relevant actions: who did what, when.
Per-unit credentials
Every unit carries its own credentials, rotated automatically when it is paused, retired or re-enabled. A compromise is contained to one unit.
Individual service access
Service access to each unit is issued individually and held under audit, never one shared key across a whole fleet.
Encrypted in transit, backed up continuously
Automatic certificate renewal, point-in-time recovery and an independent daily backup with a rehearsed restore procedure.
Lifecycle
Fleets change. The record should not break.
Adding, replacing, pausing and retiring units are normal events, handled as normal events.
One-command install
A new unit is provisioned in the field with a single command. No image building, no per-site configuration.
Approved enrolment
A unit requests enrolment; an administrator reviews what it reports about itself and approves. Nothing joins your fleet unasked.
Replacement keeps the history
A replacement carries identity, history and settings across; the old endpoint is retired and linked rather than deleted.
Pause and reinstate
Pause a unit for a seasonal closure or a service hold, reinstate it later with its history intact. Paused units are not billed.
Update policiesRolling out
Manual, scheduled or automatic updates set per customer, group or unit, with site-local maintenance windows, blackout dates and a per-unit hold.
Fleet version visibilityRolling out
What every unit is actually running, at a glance, rather than what it was supposed to have received.
