Craigleith expands its snowmaking system
TechnoAlpin’s best automation customer in Canada with almost 400 fully automatic a/w stick guns is expanding again. Craigleith is just taking delivery of 100 new Rubis EVO all mated to YB automatic valves, which will bring their total of EVO and YB to 200. This new concentration of Rubis EVOs may well enable Craigleith to de-commission one of their large Centac air compress. Every time they replace one of their beloved Borax guns that have served them so well, they can free up 160 cfm. Just 100 guns could free up 16,000 cfm! Now that's energy effeciciency!
Even more interesting is what is happening in their machine room. Craigleith has always turned to us for trail automation, but 2 years ago they gave automation of the machine rooms to a competitor. Let’s just say there was some disappointment and they are ripping out the old control system and replacing it with a complete new pump and compressor control package running under Liberty, one of TechnoAlpin's snowmaking software. The same software platform that has controlled their trails for many years.
Turns out there is a lot to be gained by bringing trails and machine rooms under one central command and control. In fact under Liberty, it is the computer, based on:
- (1) the machines and resources available and
- (2) on the current weather conditions and the priorities set by the operators, which controls the opening of the guns and then manages constantly air & water resources accordingly in the machine room. This could be described as a predictive control loop.
A very different system than having a human be the intermediary between two automated systems that don’t speak to each other. Also gained is data acquisition on the whole system. Craigleith, more than most, understands that this data can help direct a strategic snowmaking plan that is worth its weight in white gold.
