The WIWA Material Fluid Heater maintains a stable spraying temperature for high‑viscosity, high‑solids materials supporting film build and finish quality. ATEX 2014/34/EU models (T4) are rated up to 500 bar and use stainless‑steel wetted parts, with options like an insulation jacket and remote thermostat control.
The Material Fluid Heater is a strong fit for hot-spraying systems where coatings need higher film builds, short drying periods, and consistent surface quality – especially when working with extremely viscous materials. In hot-spray processes, the material is heated to the desired spraying temperature using the WIWA material flow heater, helping reduce reliance on solvents to lower viscosity while maintaining an even coating temperature via circulation. It’s also positioned as an effective addition for cold working environments and injection applications, maintaining consistent temperature for injection materials and supporting faster reaction times when heat is required.
