Cellar and bar cooling that only runs when the beer needs it.

Cellar Manager V2

Cellar chillers run all night holding air the beer barely notices. Cellar Manager holds the room in a safe band overnight and through the expensive early-evening tariff window, then hands control back an hour before you open. It only ever removes cooling.

• Never adds cooling, never holds off past a safe band
• Hands back an hour before opening
• Reads Eliwell controllers over Modbus
• Cooler faults flagged weeks ahead, judged against the weather
• Plugs into a 3-pin socket — no fixed wiring
• Every change logged against a name on the portal

Cellar Manager Plus

Cellar Manager V2 with an airflow fan. When the cellar needs cooling and it's 10 °C or colder outside, it holds the chiller off and pulls cold outside air in instead — free cooling most nights of the year.

• Free cooling at 10 °C or below outside
• Outdoor condenser off at night — quieter for neighbours
• Fresh air in; heat or CO₂ can be cleared
• Saving shown net of the fan's own electricity

Savings as published for earlier Cellar Manager Plus sites; they vary with the cooler and the cellar.

Remote Optimiser V2

A remote cooler's top pump runs 24/7, busy or closed. Remote Optimiser stops it in cycles when the beer doesn't need it, learns each cooler's own set point without a survey, and re-learns at every line clean.

• Pump back to 100% the moment beer warms
• No survey — learns each cooler itself
• Flags a cooler losing capacity
• Python held within 0.3–0.4 °C in monitored trials

Smart Postmix Timer

Postmix machines keep their carbonator and chiller running all night with nobody to serve. The timer switches the machine off out of hours and back on before opening — and one press of the yellow button gives the bar drinks for 24 hours.

• 7-day timer, closed days and late nights
• 24-hour staff override, no call-out
• Fail-on: any fault leaves the machine running
• Off hours and kWh shown on the portal

£ figure is a worked example (0.3 kW average, 9½ hours off a night, 27p/kWh).

Fridge Manager

An infrared motion sensor puts back-bar bottle fridges to sleep when nobody's around and wakes them the moment someone walks up. Plug-and-play, fitted in minutes.

• 30.2% less bottle-fridge energy in monitored trials
• 13-month payback at 27p/kWh
• No rewiring or tools
• Ideal for clubs, function rooms and quiet bars

Measured trial on six bottle fridges, May–July 2026. Not for fridges storing perishable food.
