Well, distillation equipment for small volumes of rose oil is very likely available if you search the internet. We do not have a specific referral for appropriate small volume distillation equipment.
Our equipment or distilleries are custom built for big volumes. Small field of roses is most likely not effective to produce rose water or oil. For example it takes some 3.5 - 4 tons of roses to produce 1 kg of rose oil, and about 1+ ton of roses for 1,000 kg rose water.
Well, if you review the history of the rose oil that we maintain on this web site it may give you some ideas.
