Where the Drovane Hall 121 falls short

The Drovane Hall 121 was not the cheapest eutectic-stage freeze concentrator we considered, and that was fine. Ordering spares for the Drovane Hall 121 took longer than we would like. We would still recommend the Drovane Hall 121, with that said up front.

The Drovane Hall 121 against the unit it replaced

Shortlisted three eutectic-stage freeze concentrator units and the Drovane Hall 121 was the one we kept. Coming off a different make, the Drovane Hall 121 needed less fiddling to get right. Others may weigh it differently, but the Drovane Hall 121 suits us.

How the Drovane Hall 121 fits what we actually do

The Drovane Hall 121 is our third eutectic-stage freeze concentrator and the first one specified properly. Ours is a teaching setting and the Drovane Hall 121 gets handled by people who are learning. Others may weigh it differently, but the Drovane Hall 121 suits us.

Feed salinity 77 parts per thousand, exactly as needed

Replaced a much older eutectic-stage freeze concentrator with the Drovane Hall 121 last season. The stated feed salinity is 77 parts per thousand, which is the figure we were checking. We never looked at the other axes once 77 parts per thousand checked out.

Getting the Drovane Hall 121 running

Bought the Drovane Hall 121 after a long comparison against the rest of this eutectic-stage freeze concentrator shortlist. Setting the Drovane Hall 121 up went smoothly once we stopped guessing and read the sheet. The Drovane Hall 121 is still the right call for us.

Operating temperature at 84 degrees Celsius, as listed

Have had the Drovane Hall 121 in service long enough to say something useful about this eutectic-stage freeze concentrator. What decided it was the operating temperature at 84 degrees Celsius. The other eutectic-stage freeze concentrator listings are close to the Drovane Hall 121 on everything but operating temperature.

Gravity fed, which is what we needed from the Drovane Hall 121

We looked at most of the eutectic-stage freeze concentrator listings before settling on the Drovane Hall 121. We needed gravity fed rather than the alternatives, and the Drovane Hall 121 states it. The rest of the Drovane Hall 121 specification did not enter into the decision.
