Refrigeration System : (Air Cooled)
Emerson / Danfoss / Tecumseh : make compressors, 2 stage cooling system with Cascade system for ULTRA LOW TEMP. Range & Single stage system for 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).
Air Circulation : [Laminar type]
The chamber is provided with best air circulation to give better temperature uniformity this is achieved by using one set of motor & blower in baffle wall Compartment to push treated air in w orking chamber. This system gives better than 1 deg c. temp. uniformity in working chamber. Uniform forced air circulate across the shelf via air diffusers on the top wall. Uniform horizontal or vertical airflow shall be provided for maintaining uniform temperature and RH in the room. System for adjustable forced air exchange shall be provided with up to 20 air exchanges per hour of fresh air to the room or its equivalent and an option to shut it down when not required. No direct radiation on the specimen.
Cabinet Construction & Insulation :
MOC of the Chamber will be: Double walled Chamber with Inner of stainless steel 304 grade & outer of CRCA duly powder coated, PUF Insulation in between two walls.
Xenon Short Arc Lamp :
150 / 300 / 500W Max current 25 amp, Voltage 20V max, Ozen free and about 1000 hours life time in the centre of the chamber for light illumination in solar wavelength.
Power Supply :
Single Phase 230V AC, 50Hz / Three Phase 440V AC, 50Hz 500 watts power supply - 1 no. with current adjustment and current, voltage digital indicator, suitable to connect xenon light source and to get its variable intensity.
Shelves & Trays :
Stainless Steel 304 quality bar type shelves will be fitted inside the chamber adjustable up to 0.5 inches Increment/Decrement. [Qty: 02 Nos]
Sensor :
Sensors : PT-100 ‘A’ class for temp. calibrated from ERTL / NABL accredited labs.
Certification :
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.
Documentation :
To comply with the documentation requirements, we provide IQ, OQ & PQ protocols to be executed before taking the chamber in to for regular use, and support the supply with the following documents with the detail operational and service manual.
Standard Operating Procedure (SOP) Operational Manual for Controller IQ,PQ,OQ protocols certificate.
Calibration certificate of all controlling modules with traceability.
Certificate of MOC.
Test Report of chamber prior to supply with mapping certificate.
wiring diagram for ease of service maintenance.
