Nu-Calgon Bio Fresh


Ready-to-use bacteriostat, fungistat and deodorizer based upon chlorine dioxide technology. Recommended for control of bacteria, mold, mildew, fungi and yeast in IAQ applications. Its EPA registration includes application in HVACR ventilating equipment, including coils, condensate pans, filters and duct-work.


Prevents the growth of bacteria which can significantly aggravate or even initiate an allergic response. Oxidizes odors associated with bacteria, mold, mildew, smoke, animals, etc.


Evaporator coils, condensate drain pans, filters and ductwork in air conditioning systems can be an excellent breeding ground for bacteria and mold. Left untreated, it can grow and eventually affect indoor air quality, a major concern of the IAQ movement today. Use of a product like Bio-Fresh cd in a total program such as Nu-Calgon’s IAQ Assurance Program will correct this problem by inhibiting the growth of bacteria or mold.

Microbial Control

Bacteria and mold are everywhere in our environment. For many allergy sufferers, their presence and growth in the air handling system can significantly aggravate or even initiate an allergic response. Bio-Fresh cd can address this by preventing the growth of bacteria, mold, etc. It specifically reacts with the microbial’s cell wall, interfering with and preventing their growth.


The powerful active ingredient in Bio-Fresh cd oxidizes odors associated with bacteria, mold, mildew, smoke, animals, etc. in the air and in air handling units. The product does not cover up or mask the odor with alcohol or perfumes, it eliminates or “oxidizes” the source of the odor, leaving the air fresh and clean.

Toxicity & Safety

An enhanced benefit of Bio-Fresh cd is its low toxicity and safety rating from the EPA. Bio-Fresh cd does not use any environmentally damaging propellants or flammable ingredients, and may be applied to occupied spaces.

ICM Surge Protector


Surge protectors are designed to protect your equipment by dissipating momentary voltage spikes and transient power surges.


Protects your heating and cooling equipment from damaging power surges.

Everyone already knows the benefit of providing surge protection for our home computers and electronics. But most people don't consider the need for surge protection on their HVAC equipment.

Most modern furnaces and heat pumps are heavily reliant upon computer boards and other sensitive electronics.

Power surges or voltage spikes from electrical storms or power company fluctuations can cause damage to these internal electrical components.

Help protect your equipment and avoid expensive service repairs by installing the ICM Surge Protector.
