Manufactured by \u003cstrong\u003eF.I.E.M. SRL of Italy\u003c\/strong\u003e, specialists in incubator technology since 1975, the A50DP is \u003cstrong\u003eexclusively available in the UK from Gwenyn Gruffydd\u003c\/strong\u003e. It gives queen rearers a controlled, stable environment to finish capped queen cells, time emergence, and mark virgin queens before introduction — taking the guesswork out of one of the most failure-prone stages of queen production.\u003c\/p\u003e\n\u003cp\u003eThis is the compact model in FIEM's beekeeping incubator range, sized for hobbyist-to-sideline queen rearing operations working with up to 100 cells at a time. If your volumes are bigger, FIEM's larger A-100, A-140 and A-316 cabinets step up to 300, 400 and 500 queen cells respectively, with deeper interiors that also handle honey decrystallising — something the A50DP's compact cabinet isn't built for (more on this below).\u003c\/p\u003e\n\n\u003ch3\u003eBuilt for Queen Breeders, Not Just Beekeepers\u003c\/h3\u003e\n\u003cp\u003eAnyone who has tried to finish queen cells in a cell-builder colony or a makeshift box at home knows how much can go wrong in those final days before emergence — temperature swings, robbing, chilled brood, queens emerging unmarked and uncontrolled. The A50DP solves this by taking grafted cells from around day 5 post-graft through to the eve of emergence, holding them at a stable, bee-accurate temperature so queens emerge on your schedule, not the colony's.\u003c\/p\u003e\n\u003cp\u003eThis makes the A50DP a natural fit for:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eQueen breeders running grafting and cell-raising programmes\u003c\/li\u003e\n  \u003cli\u003eSideline and semi-commercial queen rearers supplying nucs and mating apiaries\u003c\/li\u003e\n  \u003cli\u003eBeekeepers raising their own replacement and breeder queens\u003c\/li\u003e\n  \u003cli\u003eAnyone needing to mark queens before introduction (best done within 4 days of emergence)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMore Than a Queen Incubator: Doubles Up for Pollen Drying\u003c\/h3\u003e\n\u003cp\u003eThe A50DP isn't a single-purpose box that sits idle outside of queen season.

The A50DP's interior is just 190mm tall — built for a single layer of queen cell frames and cell-builder slats, not honey jars or buckets — so we don't list honey decrystallising as a function of this model.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cp\u003eThe A50DP comes with its adjustable internal frame already fitted, ready to hold your cell-holder slats.
