Brivis is one of Australia’s two dominant residential evaporative cooling brands and is the most commonly serviced brand across Melbourne’s eastern, south-eastern, and northern suburbs. Melbourne homes built between the 1970s and early 2000s are particularly likely to have Brivis evaporative cooling — the brand has been a staple of the Melbourne HVAC market for decades. This guide covers the Brivis models found most commonly in Melbourne, their service requirements, typical fault patterns, and pad specifications.
Brivis Models Common in Melbourne
Melbourne service technicians regularly encounter the following Brivis evaporative cooling models in residential properties:
Brivis Braemar series (current production)
The Brivis Braemar series covers the current residential range — the BMQ, BM, and BW series covering capacities from 100 to 650 L/s airflow. These are direct-drive units (no belt, impeller fan directly on the motor shaft) with a centrifugal pump and electronic controller. The Braemar range is what Melbourne technicians install as replacement units when older Brivis or other brand units reach end of life.
Older Brivis models (still widely in service)
Many Melbourne homes have Brivis units from the 1990s and early 2000s — the Breezemaster, Colt, and earlier Braemar models. These are belt-drive units with a V-belt connecting the motor to the fan impeller. Belt wear is a regular maintenance item on these units (replace every two to three seasons). They use the same Chillcel pads as current models. Parts availability for these older units is generally good — motors, belts, pumps, and capacitors are commonly stocked by Melbourne HVAC suppliers.
Brivis Coolair (smaller residential range)
Some Melbourne town houses and smaller homes have Brivis Coolair models — compact units designed for smaller floor areas. These have fewer pads and lower airflow than the main Braemar range.

Common Brivis Faults and Repairs
Motor capacitor failure
Motor capacitor failure is the single most common Brivis fault encountered by Melbourne technicians. The capacitor is an electrolytic component with a finite service life. Symptoms: fan motor hums but does not start; fan starts slowly and takes several seconds to reach full speed; or fan stops working suddenly. Replacement is $320 to $480 as a complete job. This is not a DIY repair — capacitors store a charge that must be safely discharged.
Float valve failure
The float valve admits water to the sump and shuts off when the correct level is reached. Failure modes: valve stuck open (sump overflows onto roof and can enter ceiling); valve stuck closed (sump runs dry, pads dry out, no cooling). Replacement is $280 to $420 as a complete job, typically combined with an annual service.
Belt wear (older Brivis models)
Belt-drive Brivis units from the 1990s and early 2000s require belt inspection and replacement every two to three seasons. A worn belt may squeal, slip, or break. Belt replacement is $280 to $420 as a complete job. A broken belt will stop the fan completely — the pump continues running and the unit draws water but blows uncooled air.
Pump failure
The pump circulates water from the sump to the top of the pads via the distribution trough. Pump failure (motor failure or impeller blockage) results in dry pads and no cooling. Replacement is $380 to $550 as a complete job. Pumps typically last five to ten years in Melbourne’s conditions with good scale management.
Brivis Pad Specifications
Brivis residential evaporative coolers across all current and legacy models use Chillcel 50 mm cellulose pads. The primary variable is pad dimension — height and width — which is determined by the unit size and model.
Common Brivis pad dimensions encountered in Melbourne service calls:
- Small units (150–250 L/s): typically 285 mm x 290 mm x 50 mm, 3–4 pads
- Medium units (300–450 L/s): typically 285 mm x 495 mm x 50 mm, 4–6 pads
- Large units (500–650 L/s): typically 285 mm x 745 mm x 50 mm, 4–6 pads
Always measure existing pads before ordering or confirm the unit model number on the roof unit data plate label. For full pad replacement costs, see our pad replacement guide.
Brivis Controller Guide
Melbourne Brivis installations use various controller generations depending on when the unit was installed:
Brivis Touchpad / Touchplus controllers
Current Brivis residential units are controlled by the Touchpad or Touchplus wall controllers — digital touchscreen units with speed, pump on/off, and timer functions. Common fault: communication error between controller and roof unit, usually caused by a loose or corroded low-voltage cable at the roof unit junction box. Symptom: E7 error code on the controller display. Fix: check and reseat the cable connector at the junction box — this is a non-electrical cable (low voltage) and safe for the homeowner to check with the system off.
Older rotary dial controllers (pre-2000 installations)
Many Melbourne homes with 1990s Brivis installations have simple rotary dial controllers. These are robustly reliable — faults are typically fuse related or motor related rather than controller failure. Replacement controllers are still available from Brivis service agents and most Melbourne HVAC suppliers.
