LOS-NT1, NT2, NT3, NT4 Series / LOS-NTW Series

Electric/Microcomputer Controlled Vacuum & Gas Flushing Impulse Sealer for Large Size Packaging

Vacuum, Gas flushing & Seal for large size bag - 4 types of vacuum pump for NT series

When you want to flush the air inside the bag and reduce the package volume, or when you want to utilize oxygen scavenger to extend product life, you can use the Vacuum Sealing function.

When you want to fill the bag with nitrogen gas to prevent oxidation, or with carbon dioxide to create bacteria static or insect-repellent effects or to prevent spoilage and mold growth, you can use the Gas-flush Sealing function.

The LOS-NT/NTW series sealers are long-length sealers capable of creating both vacuum and gas-flush seals.

ONPUL

Setting the ideal sealing condition

The most prominent feature of the Onpul System is the ability to set and maintain the ideal sealing condition.

The heating temperature setting is made possible through the use of a high-sensitivity temperature sensor for temperature control, and a microcomputer controller.

You can now complete the heating process at just the right temperature for melting the film regardless of the air temperature or fluctuations in the machine temperature.

• Seal heating temperature: 60 to 250ºC/ 140 to 480˚F
• Seal cooling temperature: between 40ºC/100˚F and the seal-heating temperature

The seal-cooling temperature must be set at a value lower than the user-defined heating temperature setting. If the cooling temperature is set at a value too close to the heating temperature, cooling will not take place and result in the shortening of the life of some parts, including the Teflon part.

Easy-to-operate microcomputer controller

The selection and setting of work method and vacuum method, as well as of gas-flush method and its frequency, are all controlled at the microcomputer controller.Simply press the touch panel buttons for the settings.

Use of I-heating element

Use of I-heating element, which expands relatively little when heated, reduces the chance of the heating element breaking in the middle. Its use also prolongs the life of peripheral components such as the temperature sensor that comes in contact with the heating element.

Adjustable head height

The height of the head of the sealer can be adjusted to suit the package content by operating the buttons on the side of the machine.

• When the bag is set vertically to the head: 800 to 1370mm (31.4 to 53.9 inches)
• When the bag is set horizontally to the head: 1020 to 1590mm (40.2 to 62.6 inches)

Tilting the head angle

By turning the adjuster knob, the tilt angle of the head can be variably adjusted between 0 and 90 degrees to suit the package content. For example, when packaging powders, tilting down the sealer head will allow the sealing to complete without powder spilling from the bag opening.

Integrated exhaust system

The exhaust air from both the driving compressor and the vacuum pump is released from the machine through a 5-meter (16 feet) 12⌀ tube.

Disconnection alarm

In the event the heating element is disconnected, the LCD screen on the microcomputer controller will alarm the user.
