Weatherproof and Sound Attenuated Trolleys

Make Your Own Canopy
We have developed the barriers & Acoustic Modules, which facilitate to convert Existing DG Set without disturbing existing civil work. Many of our customizing features we provide at little to no charge. "Do it yourself Soundproofing".
Barrier Panels can be screwed directly to any existent wall or framework for quick and easy soundproofing. Convert your any DG room into a sound Attenuated Room, it's that simple don’t be afraid. Customizing may be less expensive than you think.
Why go Modular?
Ease. Standard construction techniques are ill suited to your unique needs. Concrete or stud walls would need to reach expensive and inefficient thickness to provide the level of sound isolation achievable with modular panels. 
Appearance. Modular no longer means unattractive. Ose modular Acoustic Rooms offer a wide range of window styles, ceiling heights. Flooring options. Acoustic Barriers / modular panels are subjected to acoustical testing before dispatch to ensure the highest level of sound isolation. In future if your needs changes, modular construction allows rooms to be moved, reconfigured or enlarged as your needs expand, without high costs or the loss of acoustical integrity.
Remember : We can customize your DG Room to meet your specifications !
Including : You can choose to have
1. Different sizes barriers.
2. Door sizes or location.
3. Height, width, &/or length.
4. Special panel sizes.
5. Ventilation options.
6. No. Of doors, windows, window size's) & / or location.

Electrical Control Panels

Automatic Mains Failure Control Panels :
The Automatic Mains Failure Control Panels is designed to monitor (& to start Generator automatically) the mains source and upon partial or full failure of the source / Main supply.
hen mains fail, then it is sensed by Line Voltage Monitor (L.V.M.) and three starting pulses are given to Genset.
If Genset does not start within three attempts, then ‘Starting Failure’ alarm is sounded and stop signal is given to Genset to stop it fully & no start signals are given further.
If Genset starts within three attempts, then remaining starting pulses are automatically cut-off.
When Genset starts successfully, it builds up the rated voltage and Genset contactor/breaker is closed automatically. The load then is switched on / transferred to the Genset.
When Mains restores, which is checked by L.V.M. for its healthiness, the generator is then disconnected from the load and automatic transfer back to the mains source takes place, with the generator running on a cool down period and resetting ready for next failure. Load is now connected to the mains.
Electrical Control Panels 
Genset is then run for about 5 minutes time set, on no load and it is stopped automatically.
The cycle can be repeated if Mains fail again
Safeties like L.L.O.P., H.W.T. and over speed (optional) are operative when the Genset is
Running. For any of the above faults, Genset stops immediately.
Additional safeties can be added, if it is a specific requirement of the customer.
Automatic function can be totally by-passed and Genset can be started-stopped in manual mode also.
While the load is connected to Mains, the Genset can be tested for its performance in TEST mode also. In TEST mode, the total automatic cycle can be tested, without closing the Genset breaker.

Auto Synchronizing and Auto Load Sharing of DG Sets


Single Line Diagram


When mains are healthy, then both the D.G. Sets remain in the standby mode.
When mains fail, Line Voltage Monitor (L.V.M.) senses it. Starting pulses are given to the Master D.G. Set. (Master D.G.Set is automatically selected by program.)
After satisfactory starting of the D.G.Set 1, voltage is sensed by Generator Voltage Monitor (G.V.M.). If voltage is healthy, then closing signal is given to D.G.1 breaker and it is closed.
  • Giving corresponding pulses from the Synchronizing Panel can then automatically start load
  • The load is then sensed by KW transducer in the panel & continuously monitored by Programmable Logic Controller ( P.L.C.)
  • Engine & Alternator parameters are also continuously monitored by P. L. C. in the Panel. In case of any fault (e.g. Low Lube Oil Pressure, High Cooling Water Temperature etc.), breaker is tripped & engine is stopped.If the load reaches & crosses 80 % of the rated capacity of the D.G. 1, then starting pulses are given to the second D.G.set from P.L.C.
  • When D.G.2 starts, then again G.V.M. checks the voltage, and if voltage is healthy, then breaker 2 is closed
  • After closing of the second breaker, Auto load sharing function starts sharing the load between the two D.G.Sets. The percentage of sharing is directly proportional to their individual capacities.
  • Since sharing is proportional to their respective capacities, even D.G. Sets of different capacities can be synchronized successfully.
  • D.G.sets continue to run in Synchronization until the load is above 80 % of any one D.G. Set.
  • When load comes down below 80 % of any one D.G.Set, then the automatic signal is given to that D.G. & then it starts taking the full load.
  • After transferring the total load to one D.G. (on which 80 % load is to be connected), the breaker of the second D.G.is opened. Now one D.G.is taking the load, which is less than 80 % of its rated capacity.
  • The second D.G. is then stopped after its cooling period.
  • The programme is repeated automatically for any variation of the load.
  • When mains are resumed, then load is transferred to the mains & both the D.G.sets are stopped after their cooling period.
  • The percentage setting is programmable which can be set at any value upto say 90 %.
  • For stable operation even for sudden variations in the load, programmed timers in PLC are used, which take action only after stabilization of the load.
  • The total Automatic operation has a manual override. In manual mode, the total operation can be performed manually.
  • Auto load shedding facility can be incorporated by suitable programming of PLC. With this facility, various loads can be brought in or switched off at particular time or for various intervals.
  • With the same logic, 3, 4 or 5 sets of equal or different capacities can be Synchronised, with Auto load sharing facility.
