What does CoolTech do?
CoolTech is a commercial refrigeration controller with a web console attached. It is installed on the walk-in coolers and freezers, reach-ins, prep tables, display cases and cold rooms you already own, and it runs the refrigeration cycle on them — compressor, defrost and fans. While it does that it reports every reading to one console called CoolTech Central, sends alerts by email and text when a unit drifts out of range or stops reporting, lets you change setpoints and defrost settings from a browser, and keeps the temperature logs a health inspector asks for. It is used by restaurants, grocery and convenience stores, cold storage operators, and refrigeration service contractors.
Is CoolTech a controller or a monitoring system?
It is a controller. That is the difference that matters most when comparing it to anything else on the market. Most products sold for this are sensors that watch equipment run by somebody else's controller — they can tell you a walk-in is warming up, but they cannot do anything about it. CoolTech replaces the control on the unit, so it decides when the compressor runs, when defrost starts and stops, and how the fans behave. The monitoring, alerting and compliance logging are what it reports while doing that job, which is why a problem it finds is a problem it can also fix.
Do I need to buy new coolers or freezers?
No. CoolTech fits the commercial refrigeration equipment you already own. It is wired into your existing walk-ins, freezers, reach-ins and cases by a refrigeration technician during a normal service visit, and takes over the control side — you keep the boxes, the compressors and the coils. Replacing a whole cooler to get remote control and alerting would rarely be worth it, which is exactly why CoolTech is built to retrofit.
How is CoolTech different from a temperature data logger?
They are different categories of product. A data logger records temperature and waits for someone to download it, so you learn about a failure after the product is already lost — and even when it does alert you, it cannot change anything, because it is not connected to the refrigeration controls. CoolTech is the controller: it reports continuously, alerts you while the problem is still fixable, and lets you correct a setpoint or a defrost schedule from a browser instead of driving to the site. It also produces the same compliance logs a data logger produces, so it replaces the logger rather than sitting alongside it.
What happens if the internet goes down?
The refrigeration keeps running exactly as configured. This is a direct consequence of CoolTech being the controller rather than a cloud service: the compressor, defrost and fan decisions are made by the controller on the unit itself, so an internet outage never affects whether your product stays cold. The unit continues recording its own history while offline and uploads the gap when the connection returns, so your temperature log has no hole in it. You lose remote visibility during the outage — not refrigeration and not records.
Can I see all my locations in one place?
Yes. Every unit across every location appears on a single fleet screen, with each site carrying its own timezone so overnight windows and reports read correctly locally. Units can be grouped across sites — for example every walk-in freezer in the estate — and alerts, reports and user permissions can all be scoped to a customer, a location, a group, or a single unit.
