ESPIN-NANO Model VFX

Description	Specification
Power Supply	0-100 KV DC 1mA With voltmeter & microammeter Max Current 1 mA Vary Voltage by means of front panel 10- turn potentiometer. With Dial containing 0-10 Turns Indicator and 100 Division marking for Each Turn With Digital voltmeter and milli ammeter Accuracy 2% Static Removal Device Shorting Stick to remove residual charges Line Regulation: < 0.05% for +/- 10% variation in input voltage Load Regulation: <0.05% for 10 to 100% Load Variation Protection against Overload & short circuit
Polymer Pump	Peristaltic pump to dispense polymer from Reservoir to Electrode Flow rate from 0.5ml/min to 50ml/min
Reservoir	200 ml Reservoir for Polymer- Removable – Provision to view polymer level in reservoir.
Tubing	Silicone tubing to connect reservoir to electrode thro peristatic pump Silicone tubing 50 meters.
Electrode	Suitable wire-based Electrode. Double wire 300 mm length The spinning electrode will be at the bottom of the chamber (spinning up), positioned horizontally. Polymer to be coated on electrode by nozzle connected to tubing from peristaltic pump.
Translation Movement A. Drum Collector	Suitable translation movement to ensure even spread of polymer in the electrode with wiping mechanism to reduce solidification of polymer in the electrode. 2 numbers - one for each wire electrode
Conveyor Collector	moving substrate Width 300 mm Length 2000 mm Speed control to vary from 10mm / minute to 1000mm/minute Simple mechanism to remove collected fiber.
Roll to Roll Collector	Roll to Roll collector moving substrate of 30 cm wide Speed control to vary from 10mm / minute to 5000mm/minute Mechanism to wind small rolls of substrate material. Primary roller to load uncoated substrate. Secondary roller to roll coated substrate Simple mechanism to load / unload the rollers Conveyor and roll to roll collector should be easily interchangeable.
Distance Adjustment	Motorized Distance Adjustment To vary distance between Electrode and collector Variable from 50 to 250 mm. Panel mounted Control
Back Light	Light to view jet
High voltage safety	All exterior surfaces safe to touch during operation Appropriate interlocks on all doors and controls Emergency stop(s) installed in operator area(s) The power supply Overload & short Circuit protection Static Discharge Stick.
Temperature and Humidity Display	Cabin heating till 45oC. Controller with Digital Display
Chemical safety	Exhaust with ducts to evacuate solvent vapors.
Cabinet	Ergonomically designed so that the operator can easily access the spinning and Substrate handling areas as needed Proper grounding to protect against electric shock. Dimensions : 1000 x 1200 x 1750 ( L x B x H ) in mm Weight : 300 Kgs With Wheels and clampers to change the location and also place it firmly on the surface.
Controls	HMI / PLC to control Peristaltic Pump, Translation movement, Distance Adjustment & Collector speed Panel mounted control to control High Voltage
