Hytrans system PHILOSOPHY.

The basic concept of the Hytrans system product revolves around using a hydraulic pumping system mounted in a base unit, which powers a hydraulic driven water pump. The advantage of a hydraulic pump is does not suffer the lift/draft disadvantages of a centrifugal pump. A conventional centrifugal pump will create an area of negative pressure when being used a s a water pump. This negative pressure area is utilized to draw water to the pump. However, the negative pressure created is a by-product of the real objective of raising the pressure of the water, as such it is very limited and inefficient. First the ability of a fire truck pump to lift water is restricted to a maximum of 3.5 metres. The practice of drawing water also requires energy and this affects the efficiency of the pump to carry out its designed task of raising pressure of the delivered water.

Hytrans system products take very different and unique technology to lift the water to the pump. First the pump is located at water height, driven by a hydraulic pump, which is mounted in the base unit above the water. Therefore, the hydraulic pump is not lifting water but pressurizing the water at source. The pump is also floating on the water surface and uses only clean water from the top of the source, not the dirty bottom water as with a suction lift pump.

The Hytrans system system can be used at pump lift heights up to 60 meters, as compared to the fire trucks 3.5 metres. This, in practical terms, means that almost any water source is available to the fire services – river, lake, sea, reservoir or hydrant system, even swimming pools. The fire service is no longer restricted to sources of water that are within 3.5 meters height of the fire truck pump.

Hytrans system equipment can provide a further advantage as it can be used over very long distances. The Twin-Combie can deliver 22,000 litres of water at 12 bar. If Large Diametre Hose (LDH) is used the Twin-Combie can deliver vast amounts of water at usable pressures over many many kilometers and the whole system is mobile and flexible.

The Hytrans system consists of various sizes of pumping units, hose pick-up and lay-down system, hose and hose containers, delivery equipment (water monitors, water purification equipment etc.) and ancillary equipment such as fittings and hose ramps. All in all the Hytrans system is a complete system that caters for the clients every need. The client does not have to match hose to pumps or pumps to vehicle engine power, the Hytrans system is stand-alone and highly efficient, making optimum use of available vehicles through the Hytrans system ‘drop-arm’ demountable system.

HYTRANS FIRE SYSTEM,

MOBILE SUPER WATER SUPPLY SYSTEM

System description

AN INNOVATIVE WATER SUPPLY SYSTEM FOR FIRE BRIGADES, CIVIL DEFENSE AND THE PETRO-CHEMICAL INDUSTRY.                                                           

v      MOBILE LARGE SCALE WATER SUPPLY

v      EXTREME LONG DISTANCES

v      UNBELIEVABLE ACCESS TO ANY OPEN WATER

v      LARGE CAPACITY

At larger fires in whatever circumstance or at any other fluid transport problem such as for instance floods, it is always necessary to be able to pump from open sources, rivers, lakes, harbours or open sea. However, the access to the water is most of the time quite impossible for standard suction pumps. Hytrans system B.V. from The Netherlands, has managed very successfully to develop a system to overcome this problem, called the Hytrans Fire System.

This HFS water supply system also proves to be a very effective system in the petro-chemical industry, providing efficient water supply as main source or as emergency back up.

The system consists of three major segments.

A very innovative hydraulic driven submersible pump, allowing quick access to any open water source.

An unique hose laying operation, deploying hose at high speed, featuring hose retrieval with a very clever automatic hose recovery system in only little time with very limited labour input.

The whole system deployed at lowest possible cost because it can be containerized and is very low labour intensive.

THE PUMP UNIT. (HydroSub)
The HydroSub pump consists of a Diesel-Hydraulic Power pack, powering a portable floating submersed pump. The uniqueness of this pump is the relative high capacity of up to 4500 ltrs/min. for the standard HydroSub and even up to 22000 ltr./min. for the larger model, despite the beneficiary characteristics such as portable, floating submersed etc.. The submersible floating pump is linked to the power pack by means of 60 meter long hydraulic hoses, allowing access to any open water at 60 meter distance from the power pack either horizontal or vertical.
Not like a standard fire truck or fire draft pump that has to stand very close to the water.

The most unique feature of the HYDROSUB is, that it is developed with a LOW WEIGHT PORTABLE pump, but still supplying LARGE CAPACITIES.

Additionally the pump features the capability to pump salt water, chemical polluted water, mud, dirt, operate from shallow water with no risk of pump failure due to cavitation.
The fact that the pump is especially designed for a long distance relay system, with an extreme FLAT CURVE, contributes also strongly to the success of the system.

LARGE DIAMETER HOSE AND HOSE HANDLING.
To really cover large distances water supply, large diameter hose must be used in order to limit friction loss. The big problem up till now has been the extreme labour intensive job to handle heavy hose. Slow unloading from trucks and a day’s job for a six man team to clear the roads of for instance 1000 meter hose used to be normal. That really limits realistic use.
HFS solves that problem. With the standard 152-mm (6-inch) system, hose can be relayed at a speed of up to 40 Km/hr., not needing manpower assistance. Recovering is done with a smart newly developed device called a Hose Recovery Unit. This HRU is capable to recover 1000 meter hose with only three persons at low labour input in only thirty minutes. It consists of a hydraulic powered double rollers with double pressure rollers, opening automatically electronic controlled to allow the couplings to pass trough.
That means that the hose does not have to be uncoupled and no manually lifting is involved anymore. Very compact sized it can be build into any existing hose layer against limited costs. The HFS system is further developed to even handle in the same way larger diameter hoses up to to 300-mm.

COST EFFICIENCY.
The whole package can be supplied in a containerized version, with:
the basic Hydrosub pump,
1000 mtr hose (alternative 3000 mtr hose),
hose recovery unit,
water supply hardware and tools, all neatly packed in just one standard sized container.
All this can be handled by only one truck chassis, saving out on at least one other truck.

The cost efficiency becomes even greater because it is proven to be feasible to deploy five containers with only one truck chassis. Other containers could be, more water supply packages or containers for other tasks such as, containers for hazmat, rescue, chemical and oil spills, command etc.  Also cost efficient is the fact that the whole system can be deployed over a distance of up to 4000 meters by only three to four persons.

With conventional equipment a huge quantity of equipment and people would have to be used, which in turn would give uncontrollable communicational and logistic problems.

Since there is no suction, no draft problem, it takes only a couple of minutes to get the system in operation.

Very easy to operate requiring minimal attention when running, it can be used over long period of time, which is a must at large scale disaster type fires.

Special provisions allow multi functional handling not only in containers but also on a trailer, helicopter, crane,

forklift etc.

CAPACATIES. For example (Standard basic HydroSub unit):
· 2500 ltr/min over 4000 meter,
· 4000 ltr/min over 1500 meter,
· 2500 ltr/min over 1500 meter and still supplying 8 bar at the end of the hose enabling to connect to ground monitors fighting fires direct without the use of boost pumps or fire trucks.
Larger pump units, still fully mobile containerized, are now available in the HFS range up to 22000 ltr./min., and also smaller units (1000 ltr/min. have been developed.

THE HYTRANS FIRE SYSTEM HAS ALREADY FOUND ITS WAY ALL OVER THE WORLD. BECAUSE:
ALL OVER THE WORLD THE PROBLEM IS, THE WATER SUPPLY.
200 units in fire brigades all over Holland, many of which in the Europoort oil and chemical industry district of Rotterdam.
To name some others.
The oil harbour district of Le Havre France, The chemical Industry of Rouen France, fire & rescue departments in the UK, for instance the Shropshire fire service, Neste Oil Co. Finland, Rasa (Exxon) refineries in El Salvador, Pemex oil industry Mexico.
Also the Dutch natural gas company NAM has chosen to build their blow-out risk control around several of these units. Several units have been delivered to Japan. The civil defence organisation of Switzerland has decided on large scale for the system. In the district if Izmir Turkey several units are operational.
Further deliveries have been made to: the civil defence of Abu Dhabi, the fire service-civil defence organisations of Singapore and Thailand, oil industries in Sweden, several fire brigades and industries in Germany and also in Belgium, etc. etc
