Tender For Supply Of Plant Growth Chambers With Controlled Light (Led) And Temperature As Per The Specifications Described Below, Bangalore-Karnataka

Tender For Supply Of Plant Growth Chambers With Controlled Light (Led) And Temperature As Per The Specifications Described Below S No. Technical Specification chamber – LED light-controlled Plant Growth Chamber 1 LED light four tier/shelves properly spaced, installed horizontally (on top) for uniform light intensity throughout the shelf (LED tubes or sidewise vertical installation is not accepted). The LED light should be broad spectrum, energy saving LED spectra with information available on the website of manufacturer/ OEM website link to be provided for verification. 2 The light intensity should be programmable from 10 to 100% dimmable through only the controller. The light Intensity should be programmable to a fluence rate of 400 μmol m−2 s−1 (without other devices added for dimming) or higher for each tier light measured at 6” from the lamps bank. Light intensity distribution should be uniform over the entire shelf for optimal plant growth on every part of the shelf (and for all the shelves). 3 Temperature should be adjustable 7 to 44°C with lights ON or higher range (±0.5°C or with better temperature stability at all ranges). 4 Temperature safety alarm, the chamber should turn off by the controller and restart when the temp. returns to normal. The system should restart automatically when the internal temp. is normal. 5 Should have a specifically designed air circulation inside the chamber, adjustable air diffuser conditioned air travels along the entire back wall, over the shelves and returns to the ceiling fans through an opening between the light fixtures and the doors. 6 One door with full access magnetic perimeter gasket and locking system with key of ~ 146x93 cm allowing full access to chamber interior. 7 A continuous compressor operation should be maintained by an air-cooled condensing unit with a hot gas bypass system for cooling and bypass-based heating. Solenoid valves, ceiling mounted evaporator growing coil with air circulation fans. 8 A minimum work shelf area of 27-30 ft3 should allow the plant growth of 26-30 cm or more between two tiers with white epoxy coated steel wire shelves. The shelf, light canopy should be adjustable as well as removable as per research need without any tool. 9 To ensure fitting in lab space, the outer dimension should not exceed W 105 cm X D 86 cm X H 198 cm or compact and the interior volume should be ~ 1100 liter ± 50 liters 10 One or more access port/fresh air-port, floor drain, casters assembly and adjustable leveling legs for easy movement in the lab. 11 Insulation should be of woodless construction using 2 thick foamed-in-place non-CFC Urethane insulation with 97% closed cell-structure density of approximately 2 lbs/ft3. 12 ISO certified and electrical safety certificate UL-508A/CCE. 13 Android based touch screen for real-time graphing. A redundant controller in case of touch screen failure to enable machine usage. 14 Programs can be configured to run manually, real time or in elapsed time. Continuous, diurnal, and multi-step program features. Multiple programs storage with a multistep feature. Two calibrations offset to be provided, light lifetime maintenance alarm audio & visible, graphic display actual and set value, view program steps and sequence time duration. 15 Dual experiment protection via integrated yet independent temp. limit troubleshooting with the shutdown feature. 16 Troubleshooting with on board diagnostics. 17 Low and high temperature deviation alarm (audio and visual), ambient temperature monitoring. 18 Minimum four level protection for controller operation/ safety & security 19 Warranty period of minimum two-years and one year AMC. 20 All the specifications asked should be clearly highlighted in the product brochure, writing yes (copy paste) in the compliance/Catalog will not be considered as a valid argument which may lead to disqualification. Demo if required on technical specification verification round. Performance certificate from 5 users for over one year of usage for Arabidopsis application in national labs. Enclosed users list. Complete wiring and electrical diagram to be provided with machine
