About WKL Helmstädter
WKL Helmstädter GmbH is a company founded in 1992 by Werner Helmstädter, headquartered in Elztal (Baden-Württemberg), and specialised in surface temperature control. The product portfolio includes stainless steel heating and cooling manifolds with 1" to 16 or 1 ¼" to 20 outlets, modular brass brine and industrial manifolds with 2" connection, pre-fabricated manifold stations, fixed-value control stations with 3-way mixing valve, ball valves, connection groups, manifold cabinets and electronic control technology. The products are assembled in the company's own plant and 100% leak- and function-tested; brass components are manufactured to the company's own designs by long-standing partners. The company offers customised solutions from the idea through 3D design to series production. WKL supplies system providers in the field of underfloor heating, geothermal energy/brine (heat pumps), concrete core activation and industrial surface heating; assembly is carried out partly in cooperation with workshops for people with disabilities.
