Dec. 7, 2010 - PRLog -- Motor vehicle manufacturer OKA Australia leads the way
with natural hydrocarbon refrigerants

Hydrocarbon refrigerants manufacturer HyChill Australia is pleased to announce that the Western Australian based designer and manufacturer of the “OKA” brand of special purpose 4WD on/off road vehicles is the first vehicle OEM in the world to select and use hydrocarbon refrigerants in their production line vehicles. OKA has been using HyChill’s hydrocarbons in production for approximately four years. After two decades supplying the automotive air conditioning service market, HyChill is the first hydrocarbon refrigerant brand in the world to be used by a vehicle OEM for production vehicles.

In addition, the entire line of European-built AVIA trucks, distributed by Reymer Pty Ltd, parent company of OKA Australia, will shortly go on sale and will also be equipped with HyChill refrigerants.

“This is an Australian made natural hydrocarbon refrigerant being adopted by an Australian motor vehicle design and manufacturing company providing a solution which is proven safe, provides world-beating cost and performance characteristics, and sets new standards in minimising the environmental footprint of automotive air conditioning,” says HyChill Australia’s Mr John Clark.

Andy Granger, Reymer Pty Ltd’s Head of Marketing and Business Development, the manufacturer of OKA trucks and buses says, “Compared to fluorinated gas alternatives, the vastly increased chilling performance of HyChill Minus 30EC refrigerant has many advantages for a commercial vehicle manufacturer. For example, we are confronted wpxwm with increasing levels of heat rejection from engines – an unfortunate side effect of making engines more emissions friendly. The engine and cooling system are directly below the driver’s cab so ultimately some of that heat ends up soaking into the cab structure - the
increased performance of HyChill more than compensates. Furthermore, the addition of emissions control systems means that we have less space in which to package chassis and cab equipment; using HyChill Minus 30 EC, we can gain performance points without having to increase evaporator or compressor size.”

“This announcement is a huge breakthrough for hydrocarbon refrigerants in the automotive air conditioning sector,” says John Clark, a Director of HyChill. “In the early 90’s, vested interests ran ridiculous ‘bombs in kitchens’ campaigns, trying to keep the refrigerator industry from seeing the sense in using hydrocarbons. Such campaigns can be very effective at misinforming and scaring people off – for a time. In the refrigerator case, Greenpeace had to go into business selling ‘Greenfreeze’ hydrocarbonbased
fridges in order for the rest of that industry to finally recognise how seriously they had been
misguided. Today, 35% - 40% of the world’s domestic fridges are ‘Greenfreeze’ hydrocarbon fridges and that share is increasing. Unfortunately, similar campaigns were repeatedly employed in vehicle air conditioning circles since the mid 90’s, with similar success until now. However, this announcement by HyChill and OKA demonstrates that awareness and ackowledgement of the real-world evidence that hydrocarbons are both safe and superior in vehicle air conditioning is approaching ‘critical mass’.”

“Peer-reviewed published research has already verified 20 years of safe use of hydrocarbons in the automotive service market. This announcement by the OKA Australia is a welcome and necessary progression that makes these facts even harder to ignore. I would not be at all surprised if this development marked the beginning of the overthrow of this formerly monopolised market, in a similar way that Greenpeace’s ‘Greenfreeze’ revolution did many years ago.”

“I’m excited to be at the leading edge of Greenfreeze Part Two,” said Mr Clark.
