Weltem Co.

What Weltem Co. does

Weltem Co., Ltd. (주)웰템 is a privately held South Korean manufacturer of refrigeration and air conditioning equipment, founded in 1989 and headquartered in Changwon, Gyeongsangnam-do, under Representative Director Park Jeong-woo. The company operates two factories in Changwon with five production lines and vertically integrated capabilities including laser cutting, CNC bending, spot welding, and in-house painting. Its product portfolio spans portable/movable air conditioners (WPC series, including the flagship "elephant air conditioner" 코끼리에어컨), water-cooled ACs (WPW), split-type and large ACs, heat pumps (WPH and HPC series), control panel ACs (HPA series), oil coolers (HOC and WOC), portable and stand-type dehumidifiers (WPD), air purifiers (WAP and WPA), industrial fans, ice makers, electric heaters, and far-infrared heaters (돈풍기). Differentiation rests on proprietary condensate water treatment technology (multiple Korean patents), 37 years of accumulated know-how, and certifications including ISO 9001, ISO 14001, KC, CE, and ETL.

The company monetizes primarily through one-time sales of HVAC-R equipment via three channels: (1) its proprietary D2C e-commerce shopping mall at weltemmall.com for consumers and SMBs, (2) direct B2B sales with phone-based quotation (1600-4770) and an online estimate request system for enterprise and industrial buyers, and (3) international export through distributors and channel partners spanning 70+ countries including the US, Australia, and Malaysia. Target verticals are diversified — industrial and manufacturing (factories, shipyards, logistics centers), food and beverage/restaurants, sports venues, government/public sector, healthcare, banking, education, and residential consumers. Marketing is content-driven: a Korean website with product catalog, installation case studies, technical drawings, certifications, manuals, and a cooling capacity calculator, supplemented by seasonal/annual product catalogs. The company has received the 2020 Export $7 Million Tower Award and holds sub-brands COOLZEN, COOLMA, and I-CEN alongside the parent WELTEM trademark. Revenue is not publicly disclosed.
