Do you service Donper machines in Crockett and Port Costa as well as Rodeo?

Yes, all three are in our area. Send the model and a short description of the problem, and a photo of the data plate if you have one.

How should we store our Donper over the off season?

Drain, clean and sanitize every barrel and part, dry them fully, and store the seals as the manual says. Cover the machine, keep the vents clear of stored boxes and unplug it. That makes the spring restart much easier.

Is a Donper that sat unused for a year worth bringing back?

Usually, yes. The failures after long storage are seals, drains and sometimes start components, all small repairs. We test the refrigeration before quoting, so you know about a leak or a weak compressor before you spend anything on the rest.

Donper in Rodeo

Donper commercial service.

Rodeo sits on the eastern shore of San Pablo Bay, with Crockett and Port Costa nearby. A Donper that serves frozen drinks through the warm months may sit dry the rest of the year, and restarting it brings its own problems: seals that dried out, sugar left in the drain path, and a refrigerant charge that may have leaked down slowly.

We go through a machine like that before it goes back into service, not after it leaks on opening day. Our technician is based in Benicia and takes Rodeo, Crockett and Port Costa calls. Any refrigerant work is done in house under ADRIUM's EPA 608 Universal certification. The $99 diagnostic comes first and is credited toward the repair, then a written quote. CSLB #1136642.

Common repairs we handle.

Seals dried out over the off season. Seals that sat dry for months shrink and crack, and the first batch drips from the front or foams. We replace the barrel and door seals, lubricate them with food-safe lubricant and run a test batch before you load product for customers.
Sugar dried in the drain path. Syrup left in the drip tray and drain line dries hard over the winter. The first melt then overflows onto the counter or into the cabinet. We clear and sanitize the drain path and check the cabinet for water damage.
Barrel not freezing after the restart. If the barrels spin but never freeze, the charge may have leaked down while the machine sat, or the compressor's start components may have failed. We check the start side first, then the charge, find and repair any leak and weigh in a fresh charge.
