AIR CONDITIONING, COOLING & HEATING SYSTEM: Air conditioner/refrigeration cooling system with temperature accuracy of 25°C to 28°C ± 2°C throughout the year. Specially designed cooling system for facility application. The AHU indoor unit system should be installed inside the facility and controlled from an automation control panel. ULTRA-FINE FOGGING SYSTEM: High-pressure ultra-fine fogging system with 15 to 20 microns water particle size. All pipes & fittings should be stainless steel for greenhouse application including electrification and plumbing works. High-pressure pump with appropriate motor pump (400/220 V AC, 50 cycle, three/single phase). Nozzle type: High pressures, SS body with SS insert. Nozzle ID: 0.15 mm / 0.2 mm. High-pressure pipe. Humidity will be maintained up to 85%. AUTOMATED CLIMATE CONTROL SYSTEM Automatic control panel must have the following features: Real-time clock programming of temperature, relative humidity, and lighting status. At least 20 timelines at a minimum of one-minute interval. Capability to set minimum 15 programs and one schedule with minimum 8 programs of temperature and humidity. Microcontroller-based PLC system with at least 7-inch touch HMI panel. Protection through temperature limit shutdown with restart capability and alarms for temperature/relative humidity/light (low and high deviation). Auto restart function in case of power failure with inbuilt battery. Alarm memory: 15–20 data or more. Data record facility: 15–20 days with selectable interval. Complete internal electrical wiring to connect internal screen motor, lights, etc., with control panel. All wires of appropriate size should be FRLS grade. ELECTRICAL WIRING: All wires should be copper and of desired load (Havells/Finolex or similar reputed brand). Each feature should have its own electric line with MCB and should be underground in PVC pipe complete set with A-grade work. Separate electrical work, panel board, and main switches as well. BASE WATER DRAINAGE SYSTEM: Foundation wall for all sides of the facility along with buffer room. Wide base: 1 ft below earth surface, 1.5 ft above finished floor level surface, with 9” wide kick-board. Floor: anti-slippery tiles on existing floor. Floor level: 30 cm above NGL. Plinth protection: 0.6 m width all around the facility along with connecting corridor. Partition wall: 4” wide above floor level. Wall plaster with waterproof painting finish. SPECIFIC ITEMS FOR CHAMBER – A EBB & FLOW BENCH FOR PLANTS Purpose: To combine elevated benching system with a closed re-circulating irrigation system. Material: Extruded anodized aluminum top frame and legs with polymer (food-grade) tray system for keeping pro-trays/pots. Size: 4030 mm length and 1237 mm width – 3 Nos. Height: 900 mm from floor. Benches may be provided with rolling mechanism at the top to adjust walking space for observation of plants. The total facility will be provided with pro-trays designed as per requirements. Cleaning Cage & Feeding System EBB flow tray consists of water at a certain level of height with sufficient flow rate to remove fibre or growth media particles. Automatic Flood Irrigation and Drain System Each bench is equipped with individual pump, tanks, and supporting water recycling accessories. VARIABLE SPECTRUM LIGHT: PAR LED light with spectral specification of 4 wavelength spectrum (450 nm, 660 nm, 735 nm, and 5700K). Targeted coverage area: 1.2 m × 1.2 m at 0.5 m mounting height.
