Marine

Vacuum toilets and drainage systems use negative pressure to transport black and gray water through small, flexible pipes to collection units or holding tanks. From there, the water is treated or purified in accordance with maritime standards, or discharged where regulations permit. The closed system requires little water and minimizes odor and leakage risks, while the compact installation contributes to lower weight and efficient use of space on board.

This results in very low water consumption (approximately 1.2 liters per flush), a compact installation, reduced odor, low maintenance requirements, and high operational reliability.

Additional modules include:

• Membrane wastewater treatment systems
• Food waste disposers and shredders
• Compactors
• Automation & monitoring

An on-board vacuum system combines low water consumption (approximately 1–2 liters per flush) with the ability to route pipes through tight spaces, thanks to thin, straight pipes. This allows for smaller clearance requirements and quick installation or retrofitting, while the quiet operation enhances comfort for passengers and crew.

Lower freshwater consumption reduces the number of pump and tank cycles required, which lowers the load on systems. This results in lower operating costs, a longer service life for components, and a smaller ecological footprint.

River cruises require systems capable of handling peak loads during breakfast and evening hours. Evac systems are designed for quiet operation, high capacity, and a compact footprint in technical spaces. Thanks to integration with waste and food waste systems, a ship can travel longer distances without the need for supply logistics. 

For cargo ships, inland vessels, and tugboats, the focus is on reliable uptime. Evac systems are shock- and vibration-resistant, easy to maintain, and have low energy consumption. Maintenance can be performed during regular port calls, and parts are readily available through the Evac and Qua-vac network. 

Superyachts demand quiet, comfort, and premium finishes. Evac offers high-quality, quiet vacuum toilets, compact units, and advanced odour control. Piping routes can be designed with complete freedom around the yacht’s interiors.

In addition, the Evac range includes:

• HEM® fresh water systems: specifically designed for superyachts.
• The Evac Total Concept Solution: a single integrated platform for water, waste, treatment, and corrosion protection.
• A single point of contact for design, delivery, commissioning, and service.

These solutions are fully customized and tailored to autonomy, cruising area, and guest capacity.

Naval vessels are subject to the highest standards of safety and reliability. Evac solutions are redundant, shock-resistant, fail-safe, and operate reliably under extreme inclinations, vibrations, and temperature fluctuations.

We also offer:

• Segmented zones
• Rapid fault diagnosis
• Parts management in accordance with defense logistics
• Comprehensive documentation & certification
• Training for crews

Our systems can be integrated into existing vessels in a way that saves both time and money. Work can be carried out in short intervals during dry-docking, and existing tanks or piping can be reused wherever possible.

A retrofit almost always results in:

• Lower water consumption
• Less maintenance
• Less odour
• A quiet, modern system
• Greater reliability

Qua-vac provides end-to-end support:

• Commissioning
• Service contracts
• Repairs and 24/7 support
• Engineering & upgrades
• On-board training
• ISO 9001 and VCA-VOL certified
• Fast delivery of parts and kits

Remote monitoring supports predictive maintenance and minimizes downtime.

We supply individual components as well as integrated solutions for maritime water and waste management systems:

• Vacuum toilets
• Vacuum collection systems
• Wastewater treatment
• Food waste management
• Waste compactors
• Water treatment and corrosion protection systems

These solutions are in use worldwide on superyachts, river cruisers, cargo ships, and large ocean vessels.

Schedule a brief technical consult with one of our marine specialists. Based on your vessel’s specifications (capacity, crew, and routes), we will prepare a preliminary design and cost estimate. With Qua-vac, you have a single point of contact for engineering, delivery, and service, with rapid availability through the Evac and Qua-vac network.
