My 1st $800 plunger from a different vendor broke down in 2 weeks, and they had the worst customer service. After doing more due diligence, I came across Orca. I bought a 3/4 hp chiller for my 200-gallon oval pod, and it has been working amazingly. I had several questions about setup and maintenance, and they provided instant customer service. I have now had the chiller for over 2 weeks running 24/7, and the temperature has been perfect. Although the chiller was over double the price, it was well worth it. It even looks and sounds like a better, stronger unit. You won't be disappointed. You get what you pay for.
