Permafrost outreach 2009

Water/air swivels are great idea to remove cutting chip at the bit. These system require big amount of air compressor (>100 CFM) or high pressure water pump (2GPM), however, it works greatly with our portable drill system!! This swivel connects water or air line during rotation (drill power head). In general, actual drilling system includes three major components to digging ground, 1) rotation action, 2) high pressure forced water/air pushing action and to remove chips, 3) impact shock action. Swivel support high pressure forced water/air pushing action and to remove chips. However, once we work with permafrost, we would like to keep freezing during drilling. As a result, we need chilled (cooling) system before sending swivel. It will be minimum disturbance, when we use super cooled water or chilled air to send swivel system.
