Schenker vs Spectra

Two takes on the same idea. Schenker's ERS reaches slightly lower Wh/L at the small end and its Zen range scales further on output. Spectra's Clark pump has the longer parts and service network in Australia. On efficiency alone there is very little in it.

Modular DC systems built around Schenker's Energy Recovery System. The most efficient litres in the table, aimed squarely at solar-powered liveaboards and long-passage boats without a generator.

Spectra in one line

The original energy-recovery brand. Clark pump systems from 24 L/hr up, all DC, all in the 4 to 5 Wh/L band. Widely serviced, strong parts network, premium pricing.
