Applications

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

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 )

Lighting System

lighted shelve is lit by cool fluorescent light & tungsten incandescent light properly spaced for uniform light intensity. Intensity is adjustable upto >1100 μmoles/m2/s at 150mm distance from the lamps. Programming and control of the lighting is done controller. Barrier to prevent lamp heat to not influence the temperature of subsequent shelf.

g

Controller

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 PLANT GROWTH CHAMBER SR WIPGC A Model SRLWIPGC-12 Capacity Ltrs 4000 Litres regarding the control system 25 steps PLC with HMI based temp. & RH controller, with 50 real time use entered programs in with 99 cycles in each programs. provides precise temp., RH, Humidity, illumination & co2 maintaining uniform & accurate growth environment.
