Fuji Impulse’s VG-402/602 Series Nozzle Type Sealers feature a built-in ONPUL Temperature Control System for high precision vacuum and gas-flush package sealing. The ONPUL controls heating temperatures by measuring them right at the heating element. The system’s low-profile temperature sensor comes in direct contact with the heater, preventing the temperature from exceeding the preset temperature, and allowing for hours of operation. The microcomputer controller enables operators to choose from and easily set 13 different sealing methods. The vacuum sealing function of the VG-402/602 Series Sealers is designed to flush the air inside of the bag and reduce the package volume or for using oxygen scavenger to extend the life of the product. The gas-flush sealing function fills the bag with nitrogen gas to prevent oxidation, or with carbon dioxide to prevent spoilage or mold growth or to create bacteriostatic or insect-repellent effects.
