Local debut for cutting edge technology
THERMAL XR
HVAC efficiency meets cutting edge science
PROMEK TECHNOLOGIES DIRECTOR,
Tony Power, talks to CCN about the cutting edge technologies the company has been busy devel- oping for Australia's HVACR industry.
The innovative products developed by the Sydney-based company includes Thermal XR coating recently released after years of testing and a number of false starts.
Power said Thermal XR is a thermally conduc- tive coil protection coating embedded with pure Graphene particles only 7 Nanometres wide.
“Do a Google search on that one; that’s sev- en billionth of a metre. This is deep science supported by PHD research,” he said. “Simply spray this coating onto a degraded condenser and heat exchange is improved immediately, and it improves Coefficient of Performance (COP). Service life of very old HVACR systems can be extended by five to seven years. Delay Capex and have a payback.”
Nanofluids improve the thermal conductivi- ty of water and water is the prime working fluid in most large HVACR systems.
“Most people don’t re- alise that water and glycol are very poor conductors of heat,” Power explains. “Our soon to be released Graphene Nanofluid is

100% developed and manufactured in Australia and is a game changer.
“Early results show an energy perfor- mance improvement in chilled water sys- tems of 11% and its much higher in heat- ing and glycol systems,” he said.

“Just inject our Nanofluid into a
closed water loop and energy savings are im- mediate. Carbon is environmentally safe, no problems there.”
Promek Technologies has also released Vane Boost, a simple but important technology which eliminates condenser air bypass in situations where installers have not made an allowance for proper air movement away from a condenser.
“Condenser air bypass is a serious problem and costs millions of dollars in wasted energy and equipment failures,” he said.
“Vane Boost in effect turns an axial fan into a vane axial, with much higher air velocities. Air is discharged up to 5 meters away from heat ex- changer, noise break out is reduced and coil air on velocities have been seen to increase by up to 5.2%.” Promek Technologies is also the commer- cial distributor for Envirotemp which improves thermal conductivity on the refrigeration side.
“It's hard to get your head around that one but it is now a proven technology in Australia with high energy saving results. This technology is originally from the United States with over 100,000 successful installations,” he said.
“Coolnomix is much, much smarter than your
average smart control. Some of those have been very disappointing in the past and technicians have simply taken them out of service.
“This controller has two sensors and gives a high level of control and incorporates free cooling from residual evaporator liquid during the off cycle. Our local results have been amazing on refrigeration systems and packaged units up to 100kW.”
Going forward, Power said Promek will con- tinue to develop technologies through 2019 – 2020 particularly nanotechnology.
“These are not just for Australian release but to a broader market. In mid 2019 we will release a patented new concept in HVAC fire and smoke detection that will be game changer; AS 1668.1 and AS 1670.1 need a shake up.
“There are also some natural refrigerant pro- jects we have been working on, so watch this space.” The company’s focus has been mostly on heat exchange improvement which is a neglect- ed space in HVACR
“We see an opportunity to improve technolo- gies that are not served well by current HVACR offerings, that’s where we want to be,” Power said. Call 1300 782 761 for details.
