100% Drain-Free Cooling Circulation Water Treatment Conditioner!

The ingredients of CALFA BAS FREE are all made from "natural minerals" and do not violate any laws or regulations, including the Water Pollution Prevention Act, Total Water Quality Regulation, Sewage Act, Soil Contamination Countermeasures Act, PRTR Act, and other laws and ordinances. Regardless of the type of facility (storage designated facilities or specific business sites), there is no need for any cumbersome administrative procedures such as notifications or declarations, no matter how much wastewater is discharged, used, or stored. Since it is "chemical-free" and "wastewater-free," it does not contain any components that would contaminate soil or groundwater. Additionally, all ingredients are fully disclosed in the SDS. Once it has served its role as cooling water, it can also be reused for watering lawns, spraying on rooftops, or asphalt. Furthermore, in the event of a disaster where the water supply is cut off, the water from the cooling tower is safe enough to be used for "washing the body."

basic information

Remove scale components (especially silica scale) that accumulate in cooling towers and heat exchangers using only safe ingredients, thereby reducing unnecessary heating costs for cooling equipment! Additionally, with excellent rust prevention effects, significantly extend the lifetime of piping, pumps, and heat exchange equipment. All ingredients are made from natural minerals and do not violate the Water Pollution Control Law, the Sewer Law, the Total Water Quality Regulation, or the PRTR Law, meaning no notifications are required regardless of the facility classification or the amount of wastewater discharged. After use as cooling water, it can also be reused for watering lawns or for sprinkling on rooftops and asphalt. There are no components that contaminate soil or groundwater, so it is completely unrelated to the Soil Contamination Prevention Law. In other words, it can be used for watering gardens and sandpits. Moreover, even in the event of a disaster where the water supply is cut off, it is safe enough to allow for "body washing." This is only possible with the green label CALFA BAS ~FREE~. * "CALFA BAS" is a registered trademark of Calfa Chemical Co., Ltd. Please be cautious of "similar products" and "imitation products (copy products)."

Applications/Examples of results

The reduction of energy and water usage, along with contributions to environmental protection, has been recognized, receiving significant evaluation and praise from engineers in Europe, known as "environmentally advanced countries." Numerous safety and efficacy tests, considered to be the most stringent in the world, have been conducted under "EU standards." Utilization for domestic water Safety tests (passed) Oral toxicity tests (passed) Skin irritation-corrosiveness tests (passed) Mutagenicity tests (passed) Legionella bacteria antibacterial tests (passed) Fish toxicity tests (passed) Eye mucous membrane irritation-corrosiveness tests (passed) As a result, "CALFA BAS" has begun to be actively adopted in the EU market and is currently gaining rapid recognition. Recently, it was awarded as a "Gold Award Product" by the Chinese Industry, Commerce, Economy, Trade Science & Technology Development Association, a national agency in Taiwan, recognizing products with "high quality" and "excellent technology" in the fields of environmental technology and energy conservation.

Calfa Chemical Co., Ltd. has developed the environmentally friendly cooling tower water treatment agent "CALFA BAS" (Calfa Bas) that is "phosphorus-free" and "nitrogen-free"! Using amorphous solid water treatment technology recognized in the environmentally advanced EU, it solves cooling tower problems (such as silica and calcium scale buildup, slime attachment, and reduced heat exchange) without the need for equipment or machinery! CALFA BAS (Calfa Bas) contains no "phosphorus" or "nitrogen" at all. Therefore, there is no need for "concentration measurement devices or systems" to measure residual amounts of "phosphorus" or "nitrogen." Additionally, actions such as diluting with water to meet "total water quality regulations" are unnecessary in themselves. [ISO 14001 compliant] Installation is simply placing it at the bottom of the cooling tower. That's all. It significantly achieves savings in water and energy! Some users in factories and large hotels have realized savings of several million yen in electricity costs over six months. By simply reducing power consumption (kWh) by 30%, the carbon dioxide emissions from power suppliers are also reduced by 30%, contributing to the mitigation of global warming, making the optimization of thermal efficiency essential.
