A Major Breakthrough in Industrial Surface Cleaning Technology

Maintenance and cleaning of a large surface area, complex superstructure, factory floor, hazmat site or municipal infrastructure is a very challenging proposition. Decontaminating and/or sterilizing such surfaces presents even more of an obstacle. STI’s new line of industrial surface cleaning equipment accomplishes all of these tasks while…

  • Recovering up to 95% of the wash water
  • Filtering out the hydrocarbons, toxins, particulates and other pollutants
  • Re-utilizing that same wash water to continue that process

Wash water recovery is mandated by the Federal Clean Water Act, every State and most of Europe. These Laws and Codes prohibit the “…concentrated pollution generated by surface cleaning of any structure other than a single-family home from entering the Storm Drainage System and then into the water table, streams and coastal waters…”. Until recently, the only solution was to recapture the waste wash water and pump it into tanker truck for processing at a facility or risk substantial fines for violations. Now, with STI’s proprietary design, full compliance is possible and, of equal importance, a superior result than that of conventional systems. All this in a superiorly engineered, ultra-lightweight and compact footprint with multiple power source platforms and peripherals.

 

STI engineers and manufactures the most powerful, compact, versatile and water saving surface cleaning machines in the world. We use only the highest quality aluminum and stainless steel structural materials and American made componentry. We build these machines in America with highly skilled American workers for use all around the globe. Whether it is a 1,000 car parking garage, natural disaster aftermath, Petro-chemical plant or transit terminal, STI equipment is built with the task and the environment in mind.

High Pressure, High Temperature, Wash Water Recovery, Filtration & Re-Use in a Compact, Ultra-Light Footprint

Multiple Geometries

STI has engineered multiple power drive configurations to meet the various needs of their customers. A gasoline fueled V-twin “Tri-Drive” system utilizes Kohler Command Pro 27 bHP fuel injected engines to drive high pressure Annovi Reverberi Triplex Piston Pumps up to 7250 PSI and a Positive Displacement 700 CFM Vacuum Pump. The system is available in an all-aluminum 7’ x 12’ semi-enclosed tandem trailer. We also offer, beginning in summer of 2018, a truck mounted Power Take-off all Hydraulic powered unit for Municipal, Military, Liquid Haz-Mat and Disaster Relief applications. Diesel-Electric Hybrid, Direct-Drive Gearbox and Plug-In Electric variants coming online in 2019.

STI can custom configure and engineer highly effective and uniquely specified equipment for the most demanding applications with state-of-the-art componentry and finest materials available, all with remarkably short lead times.

 Filtration is the Key Component

Connecting a high horsepowered drive engine to a big plunger pump has been done for years to create high flow and high water pressures. Installing a diesel fuel burner to increase operating wash water temperatures has been available for over a decade. Engine driven vacuum pumps first appeared in the seventies in carpet cleaning technology. The challenge has always been to engineer a way to filter out the oil, hydrocarbons, suspended and non-suspended particulates from the wash water in such a manner, balance and flow rate as to keep up with the increasing pump output capacities of modern plunger pumps. This limitation has forced the industry to keep pump output to inferior levels, typically ≤5.5 gallon per minute (GPM) since water filtration systems gradually decrease their throughput as the filtration media is filled with debris and waste. In a matter of an hour or two, competitors’ filtration media becomes clogged and/or depleted. The system needs to then be powered down and the media array replaced.

STI machinery has the pump output of two triplex plunger pumps on board, each producing 8 GPM and pressures to 3600 psi (7250 psi @ 4 gpm available). That is a total of 16 GPM that can be placed on target at temperatures up to 21O°F (99°C). The STI VC.20 Filtration System utilizes 20 filtration stages including oil/water separation media, random-arrayed fiber filters and particulate bag and polishing filters to filter wash water down to as small as 5-microns. Filter tanks can hold up to 300-pounds of dirt and debris. Filtration media can be replaced and debris backflushed without powering down the machine further extending time on station. With a range of up to a 300 foot radius from the equipment, work crews can service an area the size of two football fields without repositioning the equipment. Furthermore, STI equipment has a vertical range of over 30 stories.

In conventional filtration system architecture, there is a wastewater holding tank (typically 300-500 gallons). This tank is connected to a filtration array, which is made up of a complex system of pumps, valves, filtration components and a lot of hoses and pipes. This can take up a great amount of space and enormous amount of weight (8lbs per gallon) and is very difficult to balance and service. This system is then connected to a clean water tank (typically 300-500 gallons) from which the pumps are supplied the wash water. In the STI filtration systems (Multiple Patents Pending), the waste water tank is the clean water tank and the filtration system is submerged within the tank and attached to the tank, thereby eliminating 2400-5000 lbs. of water and parts and 70%+ of the space needed to transport and/or store the machinery. All this using just 3 moving parts.

STI’s VC.20 can filter over 25 gallons of waste wash water per minute, easily eclipsing any other mobile wash water filtration system on the market today.

Superior Design Resulting from Vigorous Field Testing

STI machinery was born out of 10,000+ hours of design, engineering and real-world testing on facilities such as Sea Ports, Airports, Food and Beverage Manufacturing Plants, Global Package Shipping Depots, Public Parking Facilities, Hotels and Resorts and City Streets and Plazas. These powerful systems weren’t designed by committee in a CAD Lab by a team that never operated one. Machines were “field engineered”, “field tested” and manufactured by the entire team from design to testing and every step in between. Every bolt, pump, pulley, power component, controller and hose has a reason for being exactly where it is from experience in field testing. Components are ideally situated to interact with one another and to be serviceable in the field and, in most cases, while the machine is operating. Having a overall height of 80” (6’8”) the TV.712 can easily fit into almost any parking garage and is the length of a full-sized SUV. Weighing less than 5000 pounds (dry), it can be towed by virtually any full-sized pick-up truck.

 

Replacement parts and consumable media are easily sourced directly through STI and its supply chain partners. OEM Manufacturers’ warrantees are fully-transferrable to end users and, in the case of our Kohler Engine line, Kohler has over 4,000 authorized dealers and services centers in the US alone.

Best in Class Componentry Aligned with Cutting-Edge Design

STI has teamed up with Annovi Reverberi with its line of industrial plunger pumps to provide our customers with some of the finest, most durable pump technology on the market. These powerful pumps are coupled with Kohler EFI gasoline or LP engines, the most advanced engine manufactures in the global marketplace, to provide peak performance and the harsh-condition reliability required in the field. As advanced as these drive components are, they need to be connected and interfacing with peripheral systems which control, monitor and get the washwater on target. Recovery of the waste water is done utilizing Gardner-Denver Vacuum Blowers. These manufacturers have been advancing this technology of decades and there is no question as to their superior equipment.

The advanced ergonomic and structural design of STI equipment is easy to identify and an elegant demonstration of just how clean, efficient and compact a design can become. The foundation of this design is the “Modular Crate System” onto which all of the systems and components are attached. Utilizing the Bosch-Rexroth Structural Framing System. STI trailer mounted crates are assembled with extremely lightweight aircraft aluminum extrusions and connected by patented T-Bolt fasteners providing incredibly strong connections with structural rigidity and space conservation. The crates provide a modular platform which can be detached from the flatbed trailer transport and airlifted to remote sites, such as disaster and biohazard cleanup sites or can be transported to remote marine locations for maintaining off-shore oil drilling platforms or shipping vessels.

Versatility and Purpose in Design

The TV.712 “Tri-Drive” Trailer can power multiple rotary surface cleaners, such as the Mosmatic FL.AH.750, graffiti removers, roof cleaners, up to 4 wands fitted with rotary “turbo” or fan tips or a combination of them all. This means that it can support up to 4 crew members which together can and have effectively cleaned up to 60,000 sq. ft in a shift. This translates to more rapid deployments and faster job completion times. The TV.712 can be set-up and cleaning in as little as 30 minutes. STI’s “Active Bypass System” allows first and final-stage filtration media to be changed while the equipment is in service to eliminate “down time” for the crew. At the end of the shift, oil water separation and particulate filtration media is easily removed, cartridge and bag filters replaced, and wash water and remaining solids are emptied via a single dump valve. Utilizing superior vacuum recovery, either at “point-of-contact” (like a carpet cleaner) or through “berming” or “gutter intercept”, up to 90% of wash water is recovered and pumped into the filtration system. This means that even large interior spaces such as warehouses, food and beverage manufacturing, aircraft hangars and parking garages can be effectively cleaned and maintained with no need for a drainage plan.

In a post-disaster cleanup or bio-hazard theater, the structure or surface can be dewatered, decontaminated using hyper-chlorinated, super-heated water with or without chemical spectracide injection. The waste wash water is then immediately recovered at the point of contact and pumped into hermetically sealed sequestration holding tanks or tanker trucks for removal and disposal.

Any one of our machines can utilize non-potable or even sea-water for its cleaning tasks.
