HVAC External Basic is a strong cleaner for finned condenser coil of outdoor air conditioning units and ventilation systems. Application of a high concentration of acidic compounds makes HVAC External Basic extremely effective. Cleaning process with this product guarantees long maintain and operational parameters of cleaned surfaces, increases the operational reliability and reduces energy consumption of HVAC systems.

Advantage of using HVAC External Basic is a prolonged contact with the cleaning surface. This is possible by using a suitable combination of wetting agents, which increase the adhesion strength of the product on the cleaned surface. Low-pressure washers must be used due to special surfactants present in the product. Rinsing process of residual dirt and liquid/foam can be done in two ways: low- and high-pressure washers. HVAC External Basic is completely safe for the cleaned exchanger if used in accordance with instructions. Most cleaning products for outdoor HVAC systems contain volatile compounds that irritate the respiratory system. By appropriate chemical composition HVAC External Basic is easier to use and has a pleasant, no irritating odor. HVAC External Basic is particularly effective in the case of contaminants present on the exterior of the building. It easily removes inorganic compounds, dust, salt deposits, silica and organic trees pollen (including poplar pollen), bird feathers, grass and insect residues.

Taking care of the correct condition of HVAC devices coils allows extending operation life, maintains proper cooling efficiency of the device, reduces the failure rate and energy consumption. HVAC External Basic is not intended for cleaning comfort air-conditioning units, evaporators and heat exchangers. The product should always be used in accordance with the manual guidelines. HVAC External Basic is a product for professional use only.
