Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Water Treatment Studies Bench .
Water Treatment Studies Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The studies bench comprises five interchangeable, clear PVC filter columns, each of which can be filled with a sand filter or ion exchange medias. These are fitted with top and bottom quick release couplings. Two of the columns may be used at any one time in a system of interconnecting UPVC pipework and selection valves, set to allow the columns to be circulated with dosed or untreated water either independently, in parallel, in series or in reverse, and with a backwash connection from the service water line. A panel with tubular supports is provided for storing filter columns not in use.
Dosed or untreated water is transferred from the sample tank to the filter system by a centrifugal feedwater pump at reduced pressure and a metered rate; treated filtered water is either collected in a portable 25 litre storage tank or passed to the Steam Boiler Bench, depending on the use of the unit. A variable chemical dosage system, comprising a dosage pump and a chemical additive mixing vessel, is supplied to inject diluted additive at a controlled rate to either a portable 25 litre sample tank or the boiler feedwater tank on the Steam Boiler Bench.
Pressures at the inlet and outlet of either filter column are indicated on separate 0-2.5 bar Bourdon tube pressure gauges. Sample cocks are included in the system to enable water samples to be collected for analysis by test kits supplied with the unit. A control box, suitable for either 110V or 240V a.c. supplies, provides separate ON-OFF switches and associated indicator lamps for each pump and a switch to select the pumps for either Water Treatment Studies or Feed Water Service to the Steam Boiler Bench. Filter Columns Five interchangeable clear PVC tubes each fitted with a fixed top cap and a removable bottom end cap bolted to the flange end of the tube, both caps being fitted with quick release couplings. Each column can be filled with a filter or ion exchange medium contained between top and bottom sets of water distribution discs and foam filter pads.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Double Effect Evaporator Bench.
Consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The steam bench includes an insulated separating calorimeter, equipped with a water level sight glass, connected via fixed orifice to a lagged throttling calorimeter which exhausts to a water cooled steam condenser. A mercury manometer is provided for measuring the pressure inside the throttling calorimeter and thermocouples are provided for measuring steam supply and temperatures which may be individually selected for display on an analogue temperature meter.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Steam Turbine and Condenser Set.
The turbine baseplate sub-assembly consists of a mild steel fabricated baseplate, a turbine dynamometer, surface condenser, condenser vacuum pump, condensate tank drain pump and all interconnecting pipework. The turbine is a single stage impulse type fitted with stainless steel blades. A constant speed control governor and overspeed trip are also fitted to the turbine.
The dynamometer is mounted in trunnions with the torque being measured by a load cell system. Dynamometer field control is by variable supply from the over head control unit, the dynamometer output being dissipated in a load bank. The condensate is extracted from the condenser by the electrically operated condenser vacuum pump. A small electrically driven condensate tank drain pump is used to drain condensate from the condensate tank.
Control valves and safety valves are provided in the pipework as follows:
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Lagging Efficiency Steam Bench.
Lagging Efficiency Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. The steam bench incorporates four similar mild steel tubes, each connected to a common steam supply via an inlet regulating valve and a common blowdown line via an outlet valve. Two of the tubes are unlagged but have differing finishes, namely a painted finish and a chromium plated finish respectively. The remaining two tubes are lagged, one with glass fibre webbing tape and the other with a pre-formed fibre glass insulation jacket. Each tube is fitted with a sight glass and scale to enable condensate to be measured. Surface mounted thermocouples are used to measure the temperatures at the surface of each tube and also at the extended surface of the lagging.
A thermocouple in the steam supply header is used to measure the steam temperature and a Bourdon type pressure gauge is used to measure the steam pressure. The measured temperatures are displayed on an analogue temperature meter via a selection switch. From measurements of temperature and condensate levels over a period of time, students are able to calculate the lagging efficiency and the coefficient of thermal conductivity of the lagging.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Pipe Closure Kit.
It comprises pipe work connecting the steam main to the blowdown, a steam trap and isolating valve, a direct bypass line with isolating valve and drain plug, together with blanking plugs for water supply and drainage lines.
