How can I estimate the combined capacity of Unifrost ice machines and bins?

Use a simple planning split: production (per day) plus buffer storage (ready-to-serve) plus backup (emergency).

Start with your peak demand window

Estimate how much ice you need during your busiest continuous period (for many venues this is a 2 to 4 hour service peak).

Map supply sources

Ice machine head (for example, Unifrost modular units such as U165-125 or U230-175) covers ongoing production.

Ice storage bin (for example, B175, B275AIB, B375) provides the practical “ready” buffer for fast scooping.

Upright freezer (Unifrost Upright Freezers such as F1000SV, F1300SVN, F1310SV, F410SS, F620SV) is best counted as bagged-ice backup, not primary loose-ice service.

Avoid double-counting

Don’t add “ice machine daily output” and “bin capacity” as if they are separate pools. The bin is where the machine’s ice lands, so the combined system behaves like: Machine production rate + Bin buffer.

Decide your target buffer

Many operators plan so the bin can cover the peak even if production lags briefly (busy door openings, warm kitchen, heavy draw).

Build in a contingency layer

Keep a defined number of sealed bags in the upright freezer for events, heatwaves, or machine downtime. Count this as your emergency reserve, and rotate it.

If you tell Caterboss your service style (cocktail heavy vs soft drinks), peak covers, and whether you already have a bin (for example B175) or need an ice-maker-and-bin set (for example U165-125+B175 or U230-175+B175), they can help you sanity-check the sizing without guessing.
