Extra fortified plywood cabinet

The marine-spec laminated cabinets follow the contour of the glass, and are now all fortified and made of plywood. The “floating tank” feature is now reinforced with front aluminum supports on all REEFER 625 G2+ models and bigger.

Dual return pump outlets

All REEFER 350 G2+ models and bigger now have dual side-facing return pump outlets, creating an even better water distribution.

Silent download system

The enlarged rectangular inlet to the downflow pipe (on models up to REEFER 625) reduces turbulence, making it easier to regulate.

Assembly-ready piping

All pipes are preformed with quick connectors at all joints (no gluing required). Bulkhead connectors suitable for both Metric and USA standard pipes can be purchased separately, allowing you to customize your sump piping.

High precision valve

All models now have a new and improved high precision valve on the downflow pipe, allowing for easy regulation of the flow and a near silent operation.
