Laminar Flow
Laminar Flow Model : SRL/BC-33
Laminar Flow Cabinets provides a class 100 air flow in the work area for operations where products is of utmost importance. The unrestricted open front work area allows the use of equipment under biologically clean conditions.
Application :
The Laminar Air Flow Cabinet is designed to provide a high degree of protection for process products In laboratories and production facilities. Many critical applications in the medical, pharmaceutical, nuclear-power, and micro electronic fields demand an ultra-clean work environment which is free from biological and particulate contamination.
Construction :
The cabinets are fabricated out of thick board duly sunmica clad or mild steel cabinet duly epoxy coated. The work table is made of thick board which is sunmica clad at top or S. S Table top will be provided as optional accessories. All joints are sealed with silastic sealant. Side panels are provided of thick transparent acrylic sheets. The unit is fitted with pre-filter and is made to pass through highly effective HEPA (High Efficiency Particular Air) filter having efficiency rating as high as 99.997% with hot, DOP, thus retaining all air-borne particles of size : 0.3 micron and larger.
Operation :
Ambient Air is draw in through pre-filter and is introduced in the work zone through the HEPA filter. The average velocity in the work zone is maintained between 0.4 and 0.5 m/s. Air cleanliness in the work zone is better than class 3.5 (100) in accordance with US FED STD 209 E.
Using a dynamic machine, the blower and motor assembly is statically and dynamically balanced. Blowers are mounted on vibration isolation mounts to minimize vibration. The working is illuminated by fluorescent lightings fitted to the unit. Height of the working table provides comfortable “ Sit Down†working position for the operation to work on 220/230 volts AC. supply.
Special Features :
S. S Table Top. U. V Lights attachment Front Acrylic Door Gas/ Vacuum Cock Castor wheels at the Bottom.
Power Supply :
Single phase 230V AC, 50 Hz / Three phase 440V AC, 50 Hz.
Sensor :
Rotronic Make Hygroclip non condensing type sensor for RH and PT-100 ‘A’ class for temp. calibrated from ERTL / NABL accredited labs.
Heating :
Good quality SS tubular heaters.
Humidification & Dehumidification :
Will consist of pan type humidifier tank fitted with boiler heaters, and give alarm if fault occurs or Ultrasonic Humidification System. Water reservoir tank will be connected to the humidifier. De-humidification coils are installed below the cooling coils for lower humidity.
Refrigeration : (Air Cooled) :
Emerson /Danfoss/Tecumseh : make compressors, 1 stage cooling system for TEMP. & Humidity Control. All accessories such as HPCO/LPCO, Oil Separators, Dryers, Relays, OLP etc. of Danfoss/Tecumseh Emerson Make. CFC free refrigerant to be used to comply with the New Environmental Regulation. Will have suitable tonnage compressor for maintain temperature with lights on. Will have hermetically sealed condensing unit compressor coupled with Evaporation coil and condenser, safe guarded by time delay circuit. Cabinet shall be supplied with air-cooled condensing unit with extended compressor life and close temperature control. Cooling system will be split type to place condenser unit in a ventilated area to avoid hot air in growth chamber. Cooled air shall be delivered in such a way to reduce or eliminate condensation within media dishes and to provide maximum uniformity In different research vessels. This may be through silent and durable fan motors or through any kind of advanced air diffusers. Air Cooled Condenser with solenoid & LP to pass hot gas to the chamber for uniformity & long life of compressor for continuous usage. Phenolic coating for cooling & condensing coils (All weather proof).
Safety Features :
2 minute compressor “on” delay timer to safeguard the compressor. Compressors overload relay protector. Electronic low water level cut off device to cut off the supply to boiler heater in case of low water level. Safety Temp. Controller. MCB for mains.
