Variable Inlet Vane Damper

»  AIR HANDLING ENGINEERING is an art, please consult us for your specific air handling needs.
 
 
Working Principle / General Information:
 
 » VIV Dampers are designed with mechanical principle of adjustment.
 » Inlet guide vanes are synchronously adjustable in the same angular position by a connecting element.
 » Adjustment can be made either automatically via an adjusting element from pulse generator by hand.

Special Features:
 
 » Energy Savings with fans utilizing variable inlet vanes.
 » VIV Dampers are often used for capacity modulation. They give accurate modulation and power savings over other styles of dampers at reduced air flow.
 » When an inlet vane is partially closed, each blade directs the air into the wheel in the direction of rotation and so the air is prespun. This brings about a reduction in the Capacity, Static Pressure and BHP. The amount of BHP savings at reduced capacity is determined by the type of system and type of fan-vane combination.
 » For every inlet vane position there is different Capacity V/s Static curve and Capacity V/s Brake Horsepower (BHP) curve generated by the fan.
 » VIV Dampers are designed with mechanical principle of adjustment.
 » Inlet Guide vanes are Sychronously adjustable in the same angular postion by a connecting element.
 » Adjustment can be made either automatically via an adjusting element from pulse generator or by hand.

Suction Heaters

  • Capacity 1 KW to 200 KW
Furnace Oil have Viscosity of 1500 Sec Redwood No. 1 at 100 Deg F with a fall in temperature this viscosity goes further up making oil to flow extremly difficult. To meet this demand tank suction heaters have been designed. These heaters are installed at little above the tank bottom. The beauty of the heater is that it does not heat entire tank filled with oil - it only heates the oil that flows through the heater thus cutting down the kilowatt(KW) rating which otherwise may require to heat entire oil tank. The operation is smooth and safe.

Water Ring Vacuum Pump

  • Features No lubrication is required and air or gas handled is oil free.
A balanced cylindrical rotor with hollow hub with series of curved blades running freely in eccentric casing. The sufficient sealing liquid, usually water, forms a solid ring on periphery of casing due to the centrifugal force. Since rotor is rotated in eccentric casing the blade creates working spaces whose volume increases as rotor rotates from lower to upper vertex and decreases as the rotor rotates from upper to lower vertex. The uniform distribution of working spaces on rotor periphery results in continuous suction and exhaust of gases.There is only one rotating part - balanced rotor running with close clearances without any metallic contact with other parts.The Pump has cylindrical control plates having ample area for inletoutlet port fitted with close clearances to the rotor. Axial clearances are not to be maintained and so it is very easy while in maintenance. A fitter conversant with Centrifugal Pump can handle our Vacuum Pump very conveniently. Surprisingly this Pump maintenance is less than an electric motor.

Roof Exhaust Fan

» Badly ventilated room / work shop can reduced worker efficiency by as much as 30%. Lack of fresh air means tiredness and lack of constriction resulting in more wastage and more accidents. AEROMATIC roof mounted ventilation units counteract exactly these dangers. By improving the air in the work room you improve both the efficiency and output of your workers.
 » Applications: All major industries where fumes and heat are produced such as foundries, annealing plants, welding plants, steel drawing works, rolling mills, glass plant, power plant, etc.

Flux Recovery System

Flux supply & recovery unit is working based on vacuum and high pressure pneumatic conveying system.The flux recovery is based on vacuum conveying system. the additional flux supplied to the welding point will be recovered with use of vacuum conveying and will be stored at recycle flux storage vessel. the dusty air will pass through the reverse pulse jet type filter cleaning arrangement and clean air will be exhaust of to the atmosphere.The recycle flux will be reconditioned with the help of 3 stage flux conditioning unit. the first stage will remove the large slugs particles collected during the suction. the second stage will remove the magnetic particles from the collected flux. the third and final stage will remove the dust particles from the collected flux.In one-by-one timer control system, the new flux and recycled flux will be mixed with the help of set-up timers which can be set in the hmi panel. this mixing ratio can be varied from 20% to 50% new flux to the recycle flux with the use of time control system. in this system, first we will allow to collect recycle flux, then after new flux. such cycle can be repeated depends upon requirements.

PLC based automatic Flux Supply & Recovery Unit:
Flux supply & recovery unit is working based on vacuum and high pressure pneumatic conveying system.
This system is divided in three assemblies.

1. Flux recovery and conditioning assembly
The flux recovery is based on vacuum conveying system. the additional flux supplied to the welding point will be recovered with use of vacuum conveying and will be stored at recycle flux storage vessel. the dusty air will pass through the reverse pulse jet type filter cleaning arrangement and clean air will be exhaust of to the atmosphere.
The recycle flux will be reconditioned with the help of 3 stage flux conditioning unit. the first stage will remove the large slugs particles collected during the suction. the second stage will remove the magnetic particles from the collected flux. the third and final stage will remove the dust particles from the collected flux.
The collected flux will be mixed with new flux through flux management system. we had provided two types of flux management system, one is one-by-one timer control system and other-one is online flow control mixing system.
In one-by-one timer control system, the new flux and recycled flux will be mixed with the help of set-up timers which can be set in the hmi panel. this mixing ratio can be varied from 20% to 50% new flux to the recycle flux with the use of time control system. in this system, first we will allow to collect recycle flux, then after new flux. such cycle can be repeated depends upon requirements.

2. Flux supply assemblyThis mixture of the flux will be transferred to the set of flux supply tanks. these tanks are provided with periphery type surface heater to maintain the temperature of flux to be supplied for the welding purpose. this flux will be transfer through pressure conveying system.

Oil Sealed High Vacuum Pump

 

General Information/Operating Principle:
A balanced cylindrical rotor with hollow hub with series of curved blades running freely in eccentric casing. The sufficient sealing liquid, usually water, forms a solid ring on periphery of casing due to the centrifugal force. Since rotor is rotated in eccentric casing the blade creates working spaces whose volume increases as rotor rotates from lower to upper vertex and decreases as the rotor rotates from upper to lower vertex. The uniform distribution of working spaces on rotor periphery results in continuous suction and exhaust of gases. 

 

Special Features:
 
 » LOW ULTIMATE BLANK - OFF Down to 0.1 micron Hg. and less.
 » HIGH EFFICIENCY - Even in the low Micron range.
 » UNIFORMLY HIGH PUMPING SPEED - Throughout the broad range of 500 to 10 microns.
 » RUGGED CONSTRUCTION - Designed and built for long, dependable service, even in severe applications, no special tools needed for maintenance.
