This is a fancy name for a very simple loop of pipe or tubing, attached to a spa ozonator or hot tub air blower. The top of the loop is located above the hot tub water line, and this helps prevent water from flowing back into the electrical device. Often these are complete equipment systems including pump, heater, thermostat, high-limit and pressure switches, timer, and may include an air blower. Most have Ozonator connectors. See All About Spa Packs for additional information.
Most spas manufactured today come ozone ready .
Often this means they have a place to easily install an ozone injector. For non-ozone ready spas, the ozone feed line may be attached to the air control line. This is a UV ozone generator, usually powered when the pump's electrical circuit switches on. There are several different methods for incorporating an ozonator. All rights reserved.
