<h3>Raritan Engineering: Over Six Decades of Marine Sanitation Excellence</h3><p><strong>Raritan Engineering Company, Inc.</strong> has been setting the standard for marine sanitation and plumbing since 1958. Founded on the patent for the original PH Marine Toilet — a manual head built for the U.S. Navy — the company has grown from a single-product innovator into one of the most trusted names on the water. Today, this family-owned, American-made manufacturer continues to produce a comprehensive lineup of marine sanitation and comfort systems from its facility in Millville, New Jersey.</p><p>What separates Raritan from the competition is a relentless focus on real-world reliability, environmental responsibility, and U.S.-built quality. The company's committed workforce averages more than two decades of tenure, and Raritan is known for turning orders around the same day they are received. Critically for boaters, the company stocks repair kits and replacement parts for virtually every product it has ever made — and backs each product with free technical phone support for the life of the product, with an average hold time of under one minute.</p><h3>A Legacy of Firsts in Marine Sanitation</h3><p>Raritan's history reads like a timeline of marine sanitation milestones. The Crown Head — introduced in 1966 — was the world's first macerating marine toilet, a design breakthrough that redefined onboard waste management. In 1974, Raritan pioneered the first small onboard waste treatment system, a concept that was later refined into the ElectroScan, a Type I Marine Sanitation Device that became the benchmark against which all others were measured. These innovations underscore why Raritan is a go-to brand for serious boaters who need dependable systems offshore and in environmentally sensitive No Discharge Zones.</p><p>Raritan's <a href="/7517-raritan-engineering-toilets-manual-electric-fixed-mount-parts-201081">marine toilets — both manual and electric</a> — span a wide range of models, from the legendary PHII to the premium Marine Elegance series, which features a one-piece china bowl, low water consumption, and a SeaFresh option allowing boaters to switch between freshwater and seawater flushing. These units are compact by design, engineered to fit the sloped hulls and tight quarters common on sailboats and powerboats alike.</p><p>Responsible waste management is central to the Raritan ethos. Their <a href="/7517-raritan-engineering-holding-tanks-waste-treatment-systems-200531">holding tanks and waste treatment systems</a> — including the Purasan EX and Type I/II Marine Sanitation Devices — are engineered to comply with the Clean Water Act while minimizing the vessel's environmental footprint. For boaters managing tank chemistry, Raritan's <a href="/7517-raritan-engineering-rv-water-holding-tank-treatment-18300">RV and marine holding tank treatments</a> are formulated to break down waste effectively and control odors in a way that is safe for the marine environment.</p><p>Comfort aboard a vessel goes beyond sanitation. Raritan's <a href="/7517-raritan-engineering-water-heaters-201162">marine water heaters</a>, including the 1700 Series, are built with glass-lined steel tanks for durability and feature a heat exchanger that allows the unit to tap engine heat for efficient hot water production while underway — a genuinely clever dual-mode design. And for vessels where fresh provisions matter, Raritan's <a href="/7517-raritan-engineering-refrigerators-200857">marine refrigerators and ice makers</a>, such as the Icerette, bring the same build quality and long-term parts support that boaters expect from the Raritan name.</p><h3>Why Boaters Trust Raritan Engineering</h3><ul style="list-style:disc"><li>American-made products assembled in Millville, New Jersey since 1958</li><li>Family-owned with an employee base averaging over 22 years of experience</li><li>Free lifetime technical phone support for all Raritan products</li><li>Same-day or next-day order fulfillment for most products and parts</li><li>Environmentally responsible designs built to meet EPA and Clean Water Act standards</li><li>Comprehensive parts availability for current and legacy products</li></ul>
