Smartwhip cream chargers and N2O tanks go to working kitchens in Istanbul, Antalya, Bodrum and Izmir. The site raises an enquiry rather than taking a payment: stock gets checked, the hour gets agreed, and the delivery is free.
An enquiry that carries five things gets answered in one reply. Name the item exactly as the catalogue lists it. Give the listed size -- a 666 g unit and a 10 kg tank are not interchangeable. Say how many. Give the full address with the district. Name the hour you want it, because requests are taken at any hour.
Compatibility is worth settling up front. If a regulator or culinary siphon is already on the bench, send the manufacturer and model. Whether a connector fits is decided by current manufacturer instructions, not by the product name.
Nitrous oxide is supplied for lawful culinary and food-service preparation only, handled as the manufacturer instructs and as the applicable regulations require.
The delivery costs nothing in the four cities. What gets confirmed before dispatch is stock, route coverage and the slot you picked. Official invoices follow completed business sales, with company and tax details agreed with you before the invoice is raised.
