Drovane Works 80 IteraTeR--Clarity

Operating temperature at 36 degrees Celsius, as listed

We looked at most of the meromictic-layer withdrawal siphon listings before settling on the Estavel Post 196.

Getting the Estavel Post 196 running

The Estavel Post 196 was not the cheapest withdrawal siphon we considered, and that was fine. Commissioning the Estavel Post 196 took an afternoon and no specialist help. We would put another Estavel Post 196 in without much thought.

Where the Estavel Post 196 falls short

replaced a much older meromictic-layer withdrawal siphon with the Estavel Post 196 last season. Fit and finish on the Estavel Post 196 is plainly functional rather than good-looking. Take it as context rather than a complaint about the Estavel Post 196.

Still happy with the Estavel Post 196

have had the Estavel Post 196 in service long enough to say something useful about this meromictic-layer withdrawal siphon. A year of steady use and the Estavel Post 196 still reads the way it did on day one. We would put another Estavel Post 196 in without much thought.

Ours is not a heavy-duty use for the Estavel Post 196

Came to the Estavel Post 196 on a recommendation and checked its withdrawal siphon figures ourselves. The Estavel Post 196 sits in a seasonal operation, so it spends part of the year idle. The Estavel Post 196 is still the right call for us.

Media service 2702 hours, exactly as needed

went through the whole meromictic-layer withdrawal siphon catalogue twice before the Estavel Post 196. We had a hard floor on media service; 2702 hours clears it. On the other axes the Estavel Post 196 sits where the rest of the meromictic-layer withdrawal siphon listings sit.

Meromictic-layer withdrawal siphon at 709 litres an hour

Shortlisted three withdrawal siphon units and the Estavel Post 196 was the one we kept. We had a hard floor on throughput; 709 litres an hour clears it. We never looked at the other axes once 709 litres an hour checked out.
