Gordon Enviropacks: Levels of Containment

The Gordon Brothers Enviropack has been successfully installed into areas considered to be highly sensitive to the potential release of the ammonia into the atmosphere. Industries such as mining, petrochemical, pharmaceutical, food and beverage have benefited from the installation of Enviropacks. As outlined in the levels of containment below, the Enviropack, satisfies the requirements for level 3 containment. Should an ammonia leak occur, the acoustically lined and sealed enclosure will contain any potential ammonia leaks, whilst ammonia detectors will activate an ammonia scrubbing system, which will safely absorb any air borne ammonia into a water scrubber tank. Once the ammonia detectors sense that the ammonia has been removed, the Enviropack can be entered safely.

Cascade Systems – Defrost Methods

A cascade refrigeration system can have energy consumption advantages over a more conventional two-stage industrial refrigeration system, especially where very low temperatures (in the order of -30°C and below) are required for a particular process.

Mine Cooling

It is well known that there are a number of safety issues in regards to underground mining in Australia and around the world. One of the hottest topics associated with this form of mining is the high risk of heat illness. Exposure to heat illness can lead to a loss of productivity, health issues and high worker turnover rates.
