In a typical food cold store, sixty to seventy per cent of electricity goes to refrigeration. Almost none of that plant is running the way it was commissioned to. That gap is what we are here to close.

Electric or hot-gas defrost on a fixed schedule puts heat into the chamber whether it is needed or not — and then the plant removes that heat again. Demand-based termination usually pays for itself within weeks.
Fixed condensing pressure was a control convenience decades ago. Floating it with ambient can cut compressor power substantially on cool nights, which is most of the year in many regions.
Poor staging makes machines start and stop far more than they need to. Every start is a mechanical and electrical stress event; starts per hour is the single best predictor of overhaul interval.
Fan motors add heat directly into the chamber, so you pay twice — once for the fan, once to remove its heat. Fan control on temperature or on demand fixes both.
Cold surfaces exposed to a warm plant room load the system continuously. This is the finding in the image above, and it is one of the most common.
Infiltration brings in warm, humid air, which becomes frost on the coils, which reduces heat transfer, which makes everything run longer. It compounds.
A dirty or recirculating condenser raises head pressure and pushes discharge temperature up — the fastest way to shorten the life of a compressor.
Both undercharge and overcharge cost energy and stress the machine. Neither is visible without measurement.
Pull-down, defrost and other heavy loads land wherever they happen to land. Shifting them out of the tariff peak reduces the bill without reducing a single kilowatt-hour.
Energy is the number that gets attention, but the mechanical outcome is often worth more. Compressor life is governed by three things: how often it starts, how hot its discharge runs, and what pressure ratio it works against. Every correction we make moves at least one of them in the right direction.
Longer overhaul intervals, fewer emergency call-outs, and — in a cold store — far less exposure to losing a chamber of stock.

No. Metering uses non-invasive clamps and the thermal survey is contactless — in fact the plant must be running under normal load for the readings to mean anything. We work around your schedule, including night shifts.
One to three days on site depending on facility size, then five to seven working days to deliver the report. Monitoring installations that stay permanently take about half a day.
A load map of your site, every thermal finding with its radiometric image and temperature delta, a ranked action list with estimated saving and cost for each item, and a payback calculation. Nothing is left as a generic recommendation.
We are not tied to any manufacturer. A large share of the savings we find need no purchase at all — they are setpoints, schedules, control logic and insulation. Where hardware is genuinely justified, we say so and you buy it wherever you like.
Yes. Data stays on your dashboard, is never shared, and we will sign an NDA before the first site visit if you prefer.
Most compressor wear comes from short-cycling, high discharge temperatures and running against an unnecessarily high head pressure. Fixing those reduces starts per hour and thermal stress, which is exactly what determines overhaul intervals.
It has not happened yet on an unaudited site, but the Shared Savings model exists for precisely that reason — under it, no savings means no fee.
We travel to site. Tell us where the facility is and we will confirm scheduling and any travel arrangement in the first call.
Give us a phone number and a facility. We will spend twenty minutes on a call working out whether there is enough on the table to be worth a site visit — and tell you honestly if there is not.
