Southern Hemisphere Proving Grounds (SHPG)
is an award-winning winter testing facility for automotive, component and tyre
manufacturers located in New Zealand. Nearly 50 internationally reputed
companies would gather in this $50 million complex to test their prototype cars
or tires in various winter road conditions such as ice, flats, gradients,
circles and more.
One of the internationally reputed company
is renting a track at SHPG. They would like to compare their new factory
vehicles performance between a normal, icy and snowy road conditions. They need
to condition a 150m long track to not freeze or accumulate snow. It should be
kept in an ideal condition for ABS braking development, cold fiction
evaluation, ÅÂº testing, motor control and tyre testing.
Keeping the mountain track in an ideal
condition during winters is a big challenge; especially when the average
temperature is -10¡ C and average snow accumulation are 40cm. The temperature
of the track should not be too hot that it may damage the road or melt the
tyre. Any cancellation of testing due to unmet road conditions may cost
thousands of dollars.
Additionally, any solution proposed should
not consume the time that may be utilised for automotive testing. The testing
schedule is back-to-back with limited intervals.
It is very important to maintain a
consistent track temperature throughout the duration as to not cause any damage
(such as cracks) on the tracks. An
efficient and cost-effective method must be utilised, especially, if the
Snow-melt system must continuously run for 3 months.
of tubing is installed beneath the surface of the track. St Roch Commodore Boiler got
selected to heat the polypropylene glycerol mixture that circulates through the
tubing, keeping the track at the desired temperature.
St Roch Commodore Boiler is
built with a tough hypo-eutectic cast iron combustion chamber and comes with
is paired with Bentone burner because of its energy saving capabilities
and its adherence to the environment-friendly requirements. It also helps that
this burner operates quietly.
