CSA Certification Announcement

IMPAK is proud to partner with a major Multi-National Pharmaceutical Company and to have been granted a CSA Certification for its industry leading line of Gramatech Vacuum Heat Sealers. “We are now ready to offer CSA registration as an option to our industry leading line of Gramatech Sealers,” according to Rajib Hasan, Managing Director, Machine Group.

As the company General Manager has said, “We are very proud of the machinery we have built to CSA standards.” The story below written by Alan Masnek, our resident Certified Packaging Professional (CPPL) and graduate of University of Wisconsin – Stout, illustrates the steps that were taken to design, develop and produce a piece of equipment for pharma MNC. This particular MNC is just one of the many top medical manufacturing firms we are proud to have produced product for.

Our technicians who build these heat sealers state that the Trident option provides the most value of any option on Gramatech machines.

Clean Room Ready

Machine taken into Class 100 clean room where all surfaces are wiped down with an 80/20 mix of sterile water/isopropyl alcohol then double bagged and sealed in virgin poly bags.

220V Conversion

This option allows the user to operate the unit in a facility where 220V is needed or present.

0.375″ Seal Width Upgrade

This upgrade changes out the standard 0.25″ elements up to a full 0.375″ each for a wider and more visual seal.

Extra Set of Nozzles (Trident System)

We will add an additional set of retractable nozzles which will allow you to vacuum seal up to four small bags or two medium to large sized bags at the same time. Check the Trident Nozzle option on your order.

PLEASE NOTE: If you order the Trident Extra Nozzle Set option (GO-221) and you also wish to upgrade the speed of your sealer with higher vacuum flow, you will also need to purchase the 10CFM High Flow Vacuum (OPBTVD.)

iS2 System Upgrade

The iS2 (Intelligent Sealing System) is a control system for heat sealing equipment that offers pin-point digital control over time, temperature, and pressure, via touch screen interface.

The system is more than a digital control upgrade, it combines an advanced Siemens PLC and HMI with proprietary pneumatic and electrical components, to deliver temperature control within one degree, accurate sealing time with readings every millisecond. Additional conveniences such as recipe storage, operator locks, and graphs of time/temperature put iS2 enabled sealers in a class of their own. Validation ports allow the user to confirm all parameters from a 3rd party calibration/certification service and data is available to be sent to a dedicated terminal to track and record all seals made by the unit.

10 CFM

Increases CFM from 7.8 to 10 CFM by installing an additional Venturi to the vacuum nozzle assembly.

sterile air kit

Sterile Air

Two Pre-filters with PM indicators which remove contaminants and water from the compressed air line before they reach the nitrogen generator. After leaving the generator the air is pushed through a Post filter which results in a Sterile Nitrogen flow of 99.9999+% efficiency at 0.01 micron. This is essential for food and sensitive applications where purity is critical.

nitrogen generator

Nitrogen Generator Kit

The Nitrogen generator produces Nitrogen gas (N2) from a standard compressed air line. This model is designed to generate Nitrogen at purities between 95% and 99.5%.

The Nitrogen generator can be used as a replacement for heavy and bulky Nitrogen gas tanks. Its slick and compact design allows users to integrate this with their current gas flush enabled vacuum sealers without having to worry about it taking up too much space. Also, users will not have to worry about a depleting Nitrogen gas source, as our generator produces Nitrogen from a clean compressed air source.
