Khan Associates is the authorized Koye Chemical distributor in Pakistan, supplying genuine Koye water treatment chemicals to industries nationwide. Changzhou Koye Chemical Co., Ltd., a subsidiary of the Jiaerke Group, is a manufacturer and supplier of high-quality water treatment chemicals with over 40 years of experience in the chemical industry, ISO 9001 accreditation and an on-site research and development laboratory in Changzhou, Jiangsu, China.
For Pakistani industry, Koye chemistry solves the two problems that quietly cost plants the most: scale and corrosion in cooling water systems, and microbial growth in industrial water. From phosphonate scale inhibitors to biocides and chlorination chemicals, Khan Associates supplies the complete Koye range with technical support from Lahore and Karachi.
Khan Associates holds authorized distribution rights for Koye Chemical in Pakistan. Every product we supply is genuine Koye material through the official channel, with technical data sheets and batch documentation. Backed by Koye’s ISO 9001 quality system and on-site R&D laboratory, these water treatment chemicals are supplied and supported locally by our technical team, with application guidance for your specific system.
Our Koye range covers scale and corrosion inhibitors, biocides and specialty water treatment chemicals for industrial cooling and process water systems. All product lines below are available in Pakistan with technical and dosing support.
Koye’s core range of organic phosphonate scale and corrosion inhibitors, including HEDP (CAS 2809-21-4), ATMP, PBTC and HDTMPA. These are the workhorses of cooling water treatment, preventing calcium carbonate scale and protecting metal surfaces in circulating cooling systems at power plants, textile mills and process industries.
Sodium salts of organic phosphonates such as HEDP.Na2 and HEDP.Na4 for solid dosing applications, along with polycarboxylic acid scale inhibitors and dispersants. These grades give formulators and plant operators flexibility across liquid and solid treatment programs.
Koye biocides including THPS, DBNPA, TCCA, sodium chlorite, isothiazolinones and specialty microbicides such as TCMTB and sodium pyrithione. These control bacteria, fungi and algae in cooling towers and industrial water, preventing biofouling that reduces heat transfer and blocks systems.
Sodium gluconate as a chelating and set-retarding agent, surfactants, and textile and leather processing chemicals including dyeing auxiliaries. Koye’s broad catalog supports water treatment alongside textile, papermaking and oilfield applications.
Power Plants and Cooling Systems: Phosphonate scale and corrosion inhibitors plus biocides for circulating cooling water, protecting condensers, heat exchangers and cooling towers from scale, corrosion and biofouling.
Textile Processing Units: Dyeing auxiliaries, biocides and scale inhibitors for process water, alongside chemistry supporting NEQS effluent compliance under Punjab EPD and Sindh EPA.
Oil Field and Mining: Scale and corrosion inhibitors and biocides for produced water, injection water and process circuits in demanding field conditions.
Swimming Pools and Water Disinfection: TCCA and sodium chlorite chlorination chemicals for disinfection of pool and process water.
Paper and Coating Manufacturers: Scale control, biocides and specialty chemicals for papermaking process water and coating formulations.
Industrial Process Water Systems: Complete scale, corrosion and microbial control programs for boiler feedwater, cooling water and general industrial water.
Water treatment chemistry protects expensive assets: untreated scale and corrosion shorten the life of heat exchangers, boilers and cooling systems, while uncontrolled microbial growth cuts efficiency. Our Koye support pairs genuine, consistent chemistry with local technical guidance, helping you build the right treatment program and keep it supplied reliably.
