MegaChlor-CD, from Controlomatic, of Grass Valley, Calif., is a semi-automated, saltwater chlorine generation system for pools and swim spas up to 17,000 gallons.

Features include ten adjustable power levels, builtin ability to control chlorine production and a control box with 3 buttons and 4 lights for operation that conveniently mounts to the pool or the spa’s skirt.

Polarity reverses periodically to clean and help reduce calcium buildup and Salt Level Indicator Technology lets users know when to add salt to maintain or boost chlorine production. Boost Mode allows for manual control. High Current Shutdown protects the power supply and titanium plates if there is too much salt. The cell is easy to replace and clean.

MegaChlor-CD, with 3,000 to 4,000 PPM salt concentration, provides pure chlorination of up to 0.25 pounds per day, and supports both 110 and 220 VAC supply voltages, as well as low voltage 12 VDC. A 15foot power cord and a 15-foot cell cord are included.
