For Suppliers

Close Control Air Conditioners are used where temperature and humidity need to be monitored and maintained within narrow limits. Applications include computer rooms, data processing units, telecommunication facilities and industrial process areas.

Regulatory requirements for close control air conditioners

Some close control air conditioners are subject to MEPS requirements. These requirements have been in place in Australia since 2009 and in New Zealand since 2011.

What are we working on?

We are reviewing the close control air conditioner determination as it is due to expire on 1 April 2023. This review will support the decision to let the determination expire, continue it unchanged or update it through a Regulation Impact Statement process.
