물을 보존하는 동시에 물탱크를 채우기 위해 일을 중단할 필요 없이 하루 종일 수행이 가능하도록 고안된 혁신적인 올크린(AllClean) 물재활용 시스템이 소개됐다.

 

그랜드올 인더스트리(Gradall Industries)가 개발한 이 시스템은 일련의 필터, 스크린, 원심운동을 이용해 물탱크로 되돌려보내지기 전에 잔해탱크에 집수된 물 속에서 서로 다른 크기의 물질을 제거할 수 있다.

 

 

 

An innovative AllClean water recycling system, designed to conserve water and allow operators to work all day without the need to stop work to refill the water tanks, has been introduced for Vacall AllJetVac combination sewer cleaners.

 

Developed by Gradall Industries, Inc., manufacturer of Vacall vacuum and jetting products, the AllClean recycling system uses a series of filters, screens and centrifugal motions to remove matter of different sizes from water collected in the debris tank before returning it to the water tanks.

 

“The AllClean system can be a huge resource and time-saver for municipalities and contractors who have crews out performing emergency or routine sewer cleaning work,” said Bill Petrole, Gradall Industries’ vice president of Vacall products.

 

“Instead of having to stop work to refill water tanks several times a day, our AllClean system recycles water vacuumed during jetting operations, filters it and puts it back to work. There’s virtually no downtime for maintenance because the system is self-cleaning, requires no back flushing and there are no filter changes. In addition, the water savings can amount to millions of gallons in a very short period of time.”

 

The multi-stage recycling process starts with an initial sediment separation followed by a floating V-Filtration screening process further separating water from debris. The V-Filtration also has a back-flush self-cleaning capability.

 

Centrifugal high speed action then removes remaining solids, including tiny particles down to 100 microns. Solids and fine particles are returned to the debris tank via a pressure-regulating valve system. Recouped jetted water, up to 65 percent from a sewer line, is returned to the water tanks for re-use.

 

A segregated 240-gallon capacity clean water wash down feature is also a part of the system.

 

The AllClean recycling system is another component of the Vacall “Green That Works” package of advantages, including a standard AllSmartFlow CAN bus intelligent control system, conserving water and maximizing operating efficiency.

 

AllJetVac models use just one engine instead of two for chassis mobility and to generate vacuum and jetting power -- a concept that saves on fuel consumption, routine service, harmful emissions and the purchase price of the unit.

 

The rugged, oval-shaped Vacall debris body features an innovative tailgate design that opens, closes and locks easily, with an optional flushing system that cleans out the interior of the body. Water tanks are fabricated from high-quality aluminum, mounted high to avoid road debris damage. Galvanized debris bodies and aluminum water tanks are available with lifetime warranties, expanding the machine's working life and further contributing to the “Green That Works” package.

 

Using a positive displacement system, AllJetVac machines deliver excellent jetting action and superior vacuum power to open clogged sewer lines and perform necessary routine maintenance.

 

To customize the models for specific applications and preferences, contractors and municipalities can choose decant valves, cold water recirculation system, backup hose reel hydraulics and multiple blower and water pump choices including a proprietary 87 gpm /2000 psi water pump with 30-minute run-dry guarantee. Debris tank capacities are offered in 6, 8, 10 and 12 cubic yards. Water tank capacities include 1,000, 1,200 and 1,500 gallons.
