ON2 Introduces Their New TK2 with Enhanced Structural Design Changes

In compliance with new OHS Regulations in Canada, ON2 SOLUTIONS has made extensive structural design changes to their original TommyKnocker.

The TK2 now has a 2m airlock entryway which provides easy and unobstructed access for two people, including a stretcher in case of an emergency. In addition, ON2 has added a shrouded external battery compartment, providing up to 96 hours of power and extra storage space inside the chamber.

The TK2 can also be fitted with two inches of ROXUL insulation to provide fire rating and better control the chamber’s internal temperature. With the miners’ comfort in mind, and to eliminate any additional heat buildup within the chamber, ON2 now uses only high output dimmable LED lighting to ensure cool operation with maximum LED life. These design changes not only enhance the safety of the miners, but also provide an increased level of comfort for all occupants.
