3 ...Innovation that delivers. Gas Freeing Fans Dasic Marine Gas Freeing Fans have two key benefits which ensure that Gas Freeing is carried out in the safest and most efficient manner. Firstly, each fan is uniquely designed to direct the airflow as a core to the tank bottom, reducing the risk of vapour pocket build up within the tank. This significantly reduces the time spent gas freeing. Secondly, as a safety measure, for water driven fans the water flow path is deliberately designed to be external to the air flow path. This effectively reduces the chance of water entering the air stream creating a mist in the tank which has the potential to be statically charged. W elcome to Dasic Marine Double Nozzle Tank Washing Machines Dasic Marine were early pioneers of producing Double Nozzle tank washing machines as opposed to the Single Nozzle approach. Double Nozzle machines provide significant benefits including: Lower overall operating costs Faster, more effective tank washing Shorter vessel turnaround times Higher reliability Improved cargo turnout with COW regimes Both types of machine cost approximately the same to buy and install, but reduced maintenance costs and higher reliability result in lower overall lifetime costs for the Double Nozzle system. The wash pattern of a fixed Double Nozzle machine covers the whole tank in 1/4 of a cycle. This rinse-wash is often adequate for many applications including chemical tanker pre-wash. For COW applications, bottom washing can be completed in around 20 minutes with the advantage of the whole tank having a broad clean due to wash down. In all cases the tank bottom is where most of the sediment accumulates. This is effectively impacted by a jet twice with every revolution of a Double Nozzle machine, in comparison to the single jet path of the Single Nozzle machine per body revolution. A comprehensive CD-ROM is available from Dasic Marine that compares the benefits of the Double and Single Nozzle machines.

4 T ankwashing Equipment Jetstream Model A MK II The Dasic Model A Mark II tankwashing machine is the 2nd generation of the successful Model A machine and offers a similar capacity. Over 45,000 units of the original Model A machine have been manufactured since 1968 with a good number still in service today. Key enhancements for the Model A Mark II include a new automatic 4-stage wash cycle.the 1st cycle of 20 minutes will give a 360 degree coverage of the tank with a broad based diamond pattern.the 2nd cycle of 20 minutes will also give a 360 degree tank coverage with an intesified resultant pattern.the 3rd and final cycles, each of 20 minutes, give even more intensification to the wash pattern until the fully compacted pattern is complete. A major advantage with this system is to allow a time-efficient COW procedure giving the operator the option to choose the degree of wash intensification they feel suits the in-tank condition. The Dasic Model A Mark II can be mounted under the deck-head by means of the Dasic Downpipe, which fits into a standard size tankwashing opening, or the unit may be mounted at mid height or bottom mounted in an inverted position and supplied by a pipe, normally 80 mm nominal bore.

8 Jetfan 125 Water Driven Portable Gas Freeing Fan - Up to VLCC Gas Fr eeing Equipment First introduced in 1977 the Dasic Jetfan 125 soon established itself as the most efficient deep penetration or extraction gas freeing fan on the market. Unlike products of the time the Dasic Jetfan 125 was designed to direct the air flow as a core to the tank bottom reducing the risk of vapour pockets being held within the tank. This unique method of air movement has been used successfully on vessels of up to 550K DWT tonnes, drastically reducing time spent on gas freeing operations. Despite its superb performance characteristics, the Dasic Jetfan 125 is light enough to be easily manoeuvred and positioned by one man when using the purpose built trolley. The operation to change from penetration to extraction is similarly a one man operation and can take barely 10 minutes to perform. The Dasic Jetfan 125 is designed to operate using water as the drive medium, being the most cost effective method. We can also supply the Dasic Jetfan 125 using two alternative drive mediums, Air or Steam allowing you to decide on the most practical ventilating system for your circumstances. Each Jetfan is supplied with a comprehensive instruction manual and first-aid repair kit to assist with routine maintenance.

Supply Hoses, Discharge Hoses, Transportation Trolley, Deck Opening Adaptors, Flexible Trunking, Hose Flexible Ducting Gas Freeing Ancillaries - Gas Freeing Equipment Ancillary Equipment Under normal gas freeing operations the Jetfran 125 does not require flexible ducting to perform its function effectively. Nevertheless, in certain tasks such as ventilation of void spaces, cofferdams may need an airflow to be directed around obstacles. Dasic can provide lightweight, yet rugged and hard wearing ducting to solve these problems. The ducting is constructed with a solid wire helix to maintain its diameter and ensure an effective airflow, even when used in the most restrictive of locations. The helix is stitched to a heavy duty vinyl rubbing strip to minmise damage to the ducting during use. To prevent any risk of static build-up during gas freeing operations the entire length of ducting is electrically bonded. To ensure a secure and stable mounting each length of Ducting is fitted with a Top Adaptor which is designed to allow the ducting to be suspended in a deck opening while the Jetfan unit is mounted inside the Top Adaptor. The end of the Ducting is fitted with a rigid stainless steel ring to ensure the diameter is maintained. The ring also provides a fixing point for an integral lifting rope supplied to assist removal of the Ducting. The view opposite is a typical arrangement showing the Flexible Ducting located within a tankwashing opening and the Jetfan unit being mounted inside the Top Adaptor.
