The Megatrol™ Digital Hot Tub Control we proudly offer today represents 21 years of research and experience in manufacturing spa controls and hot tub controls. Over two decades ago, we set out to design and manufacture reliable, inexpensive and easy-to-use spa controls. We have achieved those goals and gone far beyond them in our newest Megatrol™ series which is designed and produced with the highest quality materials available in the market today. The injection molded rust-free enclosure equipped with a 3.5" I.D. water manifold system reduces friction losses providing better pump performance. The inlet and outlet for the heater manifold are provided only when ordered from Table 3 with 2", 2.5" or 3" tailpieces per your specification. The patented Automatic Air Bleeder, when properly installed on the Megatrol™ manifold, releases trapped air from the heater manifold that could cause dry fire. This patented and unique feature is only available through Acura Spa Systems. A series of troubleshooting lights are provided on the upper front panel to easily diagnose most common electrical problems. The Megatrol™ is equipped with a 5,500 watt 69" long coiled heater that resulted in a lower watt per square inch density heater when compared to other manufacturers 5,500 watt 40" long heaters. The lower watt density provides longer life and less strain on the heater while producing the same temperature output. Our optional patent pending chemical resistant titanium heater is also offered upon request. The Megatrol™ offers patented and patents pending features unmatched by any other spa control or hot tub control.
For the spa manufacturer: Our hot tub control is reliable, low cost, easy to install.
For the dealer: Our spa control is easy to explain, easy to sell, easy to troubleshoot.
For the serviceman: Our hot tub control is easy to repair.
For the consumer: Our hot tub control is simple to operate and a pleasure to own!
Perhaps the Megatrol™ digital system is a case may not be improved on perfection.
