WHALE grey water tank with built-in IC sensor 12/24V. Capacity 20L. Size: 600x250x230mm. Fittings - inlets: 25mm x 4; 38mm x 40. Fittings - outlets 2 x 25mm. For pumps OS1615612 - OS1615624.   
The tank has built-in sensors for the pump automatic control and allows you to manage all grey waste on board up to 90°C even in multi-port systems. The triple spray-proof seal cover, made of polyethylene with clear inspection lid, has built-in controls kept far from water. No mobile part that easily jams. The tank has a convex base for utmost draining and a pre-moulded hose adapter for precision when boring. The "Gulper" pump can be mounted directly on the tank. Outlet ports and sensor locations minimise air pumping noise typical of the other tanks available on the market. The 20-l model offers a +25% capacity and is fitted with a dual sensor for installation of an additional pump that activates in case of large inlets or for mounting of a high-lever alarm system.
