Hobart, Tasmania
Hobart hosts computing infrastructure for the Tasmanian Government, the University of Tasmania (including Antarctic research computing through the Institute for Marine and Antarctic Studies), the CSIRO, and a growing enterprise sector. Tasmania's cool climate makes it theoretically attractive for data centre operations due to reduced cooling costs, though the limited interconnection and power infrastructure has constrained large-scale development. The state's renewable energy profile (predominantly hydroelectric) is increasingly appealing to operators seeking green data centre credentials.

Climate Factors
How Hobart's climate affects precision cooling
Hobart has the coolest climate of any Australian capital with summer maximums averaging 22 degrees and winter minimums regularly dropping to 2 to 4 degrees with frequent frost. This provides the highest free-cooling potential of any Australian city, with over 5,000 hours per year where outside air temperatures are below typical CRAC supply air requirements. CRAC compressors in Hobart may only need to run for 3 to 4 months per year in well-designed economiser systems. However, the cool, damp climate (humidity averaging 65 to 75 percent) means dehumidification remains important to prevent condensation on cold equipment surfaces. Tasmania's maritime climate produces persistent drizzle and fog that can affect outdoor condenser operations.
Services
What we deliver in Hobart
01
DX CRAC Servicing
Direct-expansion CRAC maintenance for Hobart facilities with focus on economiser optimisation to maximise free-cooling in Tasmania's cool climate. Includes compressor condition assessment since Hobart CRAC compressors experience high start/stop cycling during transitional seasons.
02
CDW CRAC Servicing
Chilled-water CRAC servicing for government and university campus systems. Valve calibration, coil inspection, glycol concentration testing for cold-weather freeze protection, and BMS integration verification.
03
Free-Cooling Optimisation
Economiser system assessment and retrofit for Hobart facilities. Tasmania's cool climate provides over 5,000 free-cooling hours annually, the highest of any Australian capital. We design both air-side and water-side economiser systems to reduce compressor runtime to 3 to 4 months per year.
04
Dehumidification Management
Hobart's damp maritime climate (65 to 75 percent average humidity) means dehumidification remains critical even when free-cooling eliminates the need for mechanical cooling. We configure and maintain CRAC humidity control systems to prevent condensation on cold equipment surfaces during free-cooling mode.

Regulatory
Regulatory environment in Tasmania
Tasmania follows the federal ARC framework for refrigerant handling. WorkSafe Tasmania administers workplace health and safety under the Work Health and Safety Act 2012 (TAS). Electrical work on CRAC control systems requires licensing from Consumer, Building and Occupational Services (CBOS). The Tasmanian EPA regulates refrigerant recovery and disposal. Government facilities in Hobart may have additional security and access requirements for maintenance of computing infrastructure serving state agencies.

FAQs
CRAC servicing in Hobart: common questions
Does CRAC Services travel to Hobart?
Yes. We mobilise to Hobart for scheduled maintenance, commissioning and emergency work. Hobart visits are typically multi-day fly-in engagements from Brisbane or Melbourne. For facilities with ongoing maintenance contracts, we schedule visits quarterly or six-monthly depending on the service level. Emergency response to Hobart is available with next-available flight from Melbourne (1 hour) or Brisbane (2.5 hours), typically arriving within 24 to 48 hours.
Can Hobart data centres run without mechanical cooling for most of the year?
With a well-designed economiser system, yes. Hobart's cool climate means outside air can provide adequate cooling for approximately 8 to 9 months of the year in a typical data centre with ASHRAE A1 temperature requirements (supply air 18 to 27 degrees). CRAC compressors may only need to run during the warmest summer months (December to February), reducing energy consumption by 60 to 70 percent compared to a facility without economiser capability. We design and commission both air-side and water-side economiser systems that maximise this free-cooling advantage while maintaining humidity control and filtration to prevent condensation and particulate ingress.
Does Tasmania's damp climate create special cooling challenges?
Yes. While Hobart's cool temperatures reduce the mechanical cooling load, the persistent humidity (65 to 75 percent average, higher in winter and during fog events) means dehumidification remains a critical function. During free-cooling mode, cold outside air can carry moisture into the facility, and the temperature differential between chilled equipment surfaces and humid air can cause condensation inside racks. We configure CRAC humidity control systems to maintain target humidity (typically 40 to 55 percent RH) independently from the cooling function, using reheat elements and humidifier/dehumidifier cycles as needed.
