Walk-In Incubator Chamber
Walk-In Incubator Chamber
Application :
These equipments are used for climatic & durability tests for botanical & zoological investigations, testing of chemicals, drugs, pharmaceutical, cosmetics, medicine, capsules etc.
Ecocentric System :
Chamber runs on the basis of Dewpoint control. Less deviations during short-term door opening & power failure. Less utility area Increased storage area. Low operating cost. Minimum power & water consumption. Reduced deviations. Less breakdowns due to standby refrigeration & humidification system. Due to PLC HMI & controlling through microprocessor based PID Temp. & RH operations the on time of both Temp. & RH system is reduced & efficiency of this system is increased with reduced energy consumption.







Construction :
MOC of the Chamber will be: Double walled Chamber with Inner & outer
of GI duly pre painted, PUF Insulation in between two walls.
Insulation of Walls, ceiling and floor : 60-80mm thick puff panels with puff in-place density of minimum of 1kg per cubic foot or its equivalent. Insulation with expended polystyrene or any equivalent material having R factor of minimum 34. Insulation material shall maintain its dimensional o 0 stability in an operating temperature range of 5 C to +60 C Insulation puff.
Door : Flush type doors of metal surfaces (as per above specification of metal) with proper puff insulation of above mentioned standard or its equivalent. Doors shall have magnetic snap-in perimeter gasket or its equivalent, self-closing cam lift gravity hinges or its equivalent, a posi-seal door closure or its equivalent. Door shall have key lockable latch handle with an inside safety release. Doorjambs shall be made fiberglass reinforced plastic or any other suitable material compatible with constructed door.
Refrigeration System :
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).
Salient Features : [Optional]
First time in India developed by SR Lab Instruments. Standby Refrigeration, Standby Humidification & Standby safety controller with auto changeover, In case of failure of the main system, To run the system for a longer with uninterrupted operation. Also USFDA approved 21 CFR compliance software, where in case of temp. & RH fluctuation, SMS & Email alert shall be sent to registered user nos and minute details of operation of the chamber can be downloaded weekly, Monthly or Quarterly
Air Circulation :
The Walk in cold room 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 working chamber. This system gives better than 1 deg c. temp. uniformity in working chamber, evaporator, heaters & steam injection system is from back side, behind baffle wall, the air circulation blower is also fitted in this compartment only. This arrangement helps to mix steam and air together and pass well mixed air inside the working chamber. 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.
Heating System :
Good quality SS tubular heaters.
Temp. Range :
+ C to C
Resolution : 0.1 C,Accuracy : ± 0.2°C, Uniformit : ± 2°C
Shelving :
Removable SS perforated trays are provided, adjustable and will slide out for easy clean up. Assembled Stainless Steel racks to accommodate trays
Controller :
PID Action : Provides Precise Temperature, Maintain Uniform
Timer, Alarm, Auto-Tuning And Auto Start Stop Function.
Technical Design and Construction Silent Fan Motor to Maintain
Uniform Temperature Over Temperature and Current Protection
Capability Ensure User Safety, Adjustable Sliding Rack, Alert
Unexpected Interruption Of Electrical Power Or
Unauthorized Change.
Optional : [PLC with HMI touch screen]
PLC Control system with touch screen display & HMI for data
Storage, Stepwise Programmable Controller with 50 or more
programs Provides Automatic Operation of Variable Temperature,
Humidity Value, 100 Or More Cycles with Minimum 100 Sections
in Each Cycle. Data logger with RS 485/232 port for logging &
transfer of data. Auto restart, power failure event logging,
memory protection S.M.A.R.T/ SELF diagnostics system. Control
system shall have audio/audiovisual warning/alarm when set
temperature/RH is below or above the set values. Ethernet
communication port. Ambient temp. Monitoring. Over Temp. and
Current Protection Capability Ensure User Safety, Adjustable
Sliding Rack, Water Level Sensor Alert Control System. Total no
of output: 23 channels. Alert Unexpected Interruption of
Electrical Power or Unauthorized Change.4 digit Password lock.
Power Supply :
Single phase 230V AC, 50 Hz / Three phase 440V AC, 50 Hz.
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.
