Actabs DMSS are EPA-registered, 2-gram micro-biocide tablets sold in 200-unit bottles. They’re designed with a timed-release dissolving formula that dispenses the treatment evenly over a four-month period to prevent algae, mold, slime, sludge, dirt, silt, and other common contaminant buildup in evaporator pans of ductless mini splits, packaged terminal air conditioners (PTACs), other small air conditioning units, and refrigeration systems. Actabs DMSS are designed for units of up to 3 ton and eliminate the need to break up larger air conditioning system tablets into ill-proportioned dosages. Actabs DMSS promotes a clean condensate pan and orifice drain that ultimately helps prevent property-damaging overflows. Actabs DMSS is also safe for all piston, diaphragm, and peristaltic style condensate pumps, and reduces periodic pump maintenance by completely dissolving particulates for cleaner and free-flowing filters.
