Applications

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

Lighting System

Three tiers of lighted shelving is lit by LED fluorescent whitelights & tungsten incandescent lamps properly spaced for
uniform light intensity. Intensity is adjustable from 600 to2000 μmoles/m2/s at 150mm distance from the lamps. Programming and control of the lighting is done controllerbetween temperature +100C to +400C. Lamps with 3 on/offlight events.Par sensor for light measurements.

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 )

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.

b

Doors

Two reach in doors for full access. 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. Magnetic gasket is provided for a tight seal.

b

Shelving

4 Epoxy coated steel shells painted in white shelves will be adjustable in 0.5 inch increment.

Co2 Application

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

Controller

PLC based PID controller with5.6” LCD is capable of controlling temperature, humidity, CO2
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 PLANT GROWTH CHAMBER

Safety Features

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.

"

Airflow/Circulation

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

"

Refrigeration

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.
