Raritan Purasan™ EX Treatment System - Pressurized Fresh Water - 12v

The Raritan Purasan EX Treatment System is a pressurized fresh water sewage treatment device engineered for cruising boaters who demand legal, reliable waste management on the water. Unlike portable heads or older treatment methods, this 12-volt system neutralizes and sanitizes waste onboard, making it compliant for discharge in non-Federal No Discharge Zone areas. Built for serious cruisers and live-aboards, the Purasan EX combines proven marine engineering with ease of operation, eliminating the need for frequent pump-outs and giving boaters genuine freedom and peace of mind underway.

The system operates on standard 12-volt DC power, making integration straightforward on any cruising vessel with basic electrical infrastructure. Raritan's treatment process chemically breaks down and neutralizes waste, rendering it sanitary and safe for the marine environment—a critical advantage over traditional black water holding tanks that require shoreside pump-out facilities. The pressurized fresh water design ensures consistent performance in offshore and coastal conditions, while the compact footprint of 15 x 10 x 23 inches fits most engine room or cabin configurations without major structural modifications. At 31 pounds, the unit balances durability with manageable weight, a consideration every naval architect and serious cruiser understands when optimizing vessel systems.

This system benefits extended-range cruisers, circumnavigators, and boaters operating outside major marina networks where pump-out services are hours or days away. The Purasan EX is particularly valuable for those planning offshore passages or extended stays in remote anchorages, where traditional holding tank capacity becomes a limiting factor in voyage planning. Installation requires basic marine plumbing connections and 12-volt DC power integration; most qualified marine technicians can complete setup in a single day. Note that HAZMAT ground-shipping applies due to chemical treatment components—plan accordingly when ordering. Verify your cruising area's regulatory status regarding treatment systems before purchase to ensure compliance with local No Discharge Zone restrictions.
