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

Lighting System

lighted shelve is lit by cool fluorescent light & tungsten incandescent light properly spaced for uniform light intensity. Intensity is adjustable upto >100 μmoles/m2/s at 150mm distance from the lamps. Programming and control of thlighting is done controller. Barrier to prevent lamp heat to not influence the temperature of subsequent shelf.

Cabinet Construction & Insulation

Interior Made of 22 guage plated steel exterior of 18 guage plated steel construction 51mm thick puff panels with puff in place dencity of minimum 1 kg per cubic foot or its equivalent. Insulation with expanded polystyrene or any equivalent. material having R factor of minimum 34 shall maintain its dimensional stability in an operating temperature range of +40C to +500C. Insulation panel or its equivalent shall have cam-type fasteners with vinyl gasket or its equivalent. Environment friendly foam (Global warming potential of 0.0 & ozone depletion potential of 0.0 )



PLC based PID controller with5.6” LCD is capable of controlling temperature, humidity and lighting. Programs may be configured to run in real time or countdown (circadian) mode. Ramping and nonramping program methods are available for each
programming mode. Multiple programs are linked to create complex environmental profiles. additional information WALK IN SEED GERMINATOR CHAMBER SR WISGC-A Model SRLWISGC- 12 Capacity Ltrs 17280 Litre GrowingHeight>135cmregarding the control system 25 steps PLC with HMIbased temp. & RH controller, with 50 real time use enteredprograms in with 99 cycles in each programs. provides precise temp., RH, Humidity, illumination & CO2 maintaining uniform & accurate growth environment.

Door shall have key lockable latch handle with an inside safety release. Magnetic gasket is provided for a tight seal.


Temperature Safety Limit Controls

(Experiment Protection) Adjustable high and low temp. controls, audible alarms, and visual in directors are provided. the controls shut down all the power to the chamber, and activates alarms. when the temperature returns to the normal range the system will auto-matically reset.


Humidity control

50% to 90% RH, + 3% Through ultrasonic humidification with high/Low
alarm. Extended humidity ranges available. It is PAN type humidifier
with RH sensor of rotronic hygroclip of SWISS make.


Safety Device

Built-in temp. deviation,audio/visual alarms. Safety thermostat for over shooting of temp. safety circuit to cut of the whole systems in case of malfunction. (only applicable to microprocessor based models). HRS fuses for compressor heaters & mains.



Uniform forced air circulate across the shelf via air diffusers on the top wall.

Co2 Application

0-2000 ppm complete with cylinders &  regulators operateddirectly from PLC with NDIR sensors.



Air cooled condensing unit which is self contained with hot gas bypass system for continues compressor operation. Temperature control in accurate and it extends its life by alternately cycling refrigerant and hot gas to the coil. Long neck solenoid values for quiet and long life operation.
