The Big Dipper is an above-ground automatic grease removal unit for commercial kitchens. Compact, cost-effective, and designed to keep your kitchen compliant with minimal maintenance.
EVAC is a partnered distributor for Big Dipper. We supply units direct, install them, service them, and report completed works to your local authority. One provider from quote to compliance.

A passive grease trap holds everything until a truck comes to empty it. The more your kitchen produces, the more often you pay for pump-outs, and the more disruption you cop while it happens.
The Big Dipper works differently. It automatically separates and removes grease as your kitchen operates, so far less waste builds up in the first place. That means fewer pump-outs, lower ongoing waste costs, and a unit that sits above ground where it's easy to access and maintain.
The unit skims and removes grease continuously while your kitchen runs. No waiting for a full trap, no relying on staff to remember.
Because grease is removed as you go, waste collection is needed far less often than with a passive underground trap.
We service your unit on schedule and report completed works to your local authority, so your trade waste obligations stay covered.
Compact, above-ground, and built for commercial kitchens that want compliance without the hassle.
Sits above ground inside or near your kitchen. No excavation, no digging up the car park to get at an underground trap.
Designed for simple day-to-day upkeep. EVAC handles the scheduled servicing so it stays that way.
Completed services reported to your local council or water authority on your behalf. Audit-ready records, no chasing paperwork.
Fewer pump-outs and less blockage risk means lower ongoing waste costs compared to running a passive trap hard.
As a partnered Big Dipper distributor, EVAC handles the whole lifecycle. You never juggle a supplier, an installer, and a separate waste contractor.
An honest guide. It's a great fit for a lot of kitchens, but not every one, and we'll tell you which yours is.
