Plant Growth Chamber

Plant Growth Chamber
Model : SRL / PGC-11

Application :

This chamber product is frequently used for research application such as lighting for plant pathology research and seedling germination and development.

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.

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.

Controller : [PLC with HMI TFT screen] :

Controls temperature, lighting, humidity and Co2 with High-definition Touch Screen for real time graphing. Programs can be configured to run in real time or elapsed time. Ramping and non-ramping program methods shall be implemented. Multiple programs can be linked creating complex sequence to simulate natural conditions. Trouble shooting with on board diagnostics. Dual experiment protection via integrated yet independent temperature limit shutdown. It shall auto-restart when temp inside the chamber comes to normal. Temperature low and high deviation alarm. Ambient temperature monitoring. Alarm (audio and visual). Power failure event logging. Auto restart in case of power failure with inbuilt battery to protect memory.
Provides Precise Temperature, Maintains Uniform And Accurate Growth Environment, 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, And Alert Unexpected Interruption Of Electrical Power Or Unauthorized Change.

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.

Double door, inner door of glass with frame & silicon gasket sealing, outer door metallic with PUF insulation.

The unit will be made of double walled leak proof metal door with lock, with a provision of opening door from inside

Forced air circulation for uniform temperature

Lockable & Movable PU wheels for easy movement

Airflow/Circulation :

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 working chamber. This system gives better than 1 deg c. temperature 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. Due to above system the temperature and humidity (R.H.) in complete chamber almost remains equal.
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.

Temperature & Humidity Range :

-10 C to +60 C, (lights ON & OFF Condition) 0 0 0 0 Resolution : 0.1°C, Accuracy : ±0.2°C, Uniformity : + 0.5 C to + 1°C
Relative humidity from 10% to 98%, Resolution : 0.1%, Accuracy : ± 2% , Uniformity : + 3%.

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).

Power Supply : :

Single phase 230V AC, 50 Hz / Three phase 440V AC, 50 Hz

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.

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.

Unit will be provided with safety devices for temperature and humidity overshoot in case of malfunction.

Built-in temp. Deviation, audio/visual alarms. Safety thermostat for over shooting of temp. Safety circuit to cut off the whole system.

OLP (Overload Protector) & Time delay Circuit for safety of compressors.

HRC fuses for compressors, Heaters & Mains
