Macro pioneered the vertical tubeless design, which quickly became the industry standard for industrial steam boilers. Since that time, no one has been able to improve upon Macro's original design.
Now Macro is raising the bar with the VSRT (Vertical Spiral Rib Tubeless) boiler, the world's first fully wetted, refractory-free vertical tubeless boiler and the new standard for industrial steam boiler design.
VSRT boilers are PURE Optimized and built to last as a reliable source of clean steam, providing cost savings and operator peace of mind for years to come.
