Firetube and watertube boilers both deliver reliable heat, but their internal design differences impact efficiency, pressure capability, and application suitability. As boiler technology evolves with AI integration and condensing advancements, today’s systems are becoming smarter, cleaner, and more energy efficient than ever before.

Isothermal and adiabatic humidification systems both improve indoor air quality — but their energy strategies differ significantly. Understanding how each system generates humidity can help facilities reduce energy costs, improve efficiency, and create healthier indoor environments.

AnnexAir revolutionized HVAC unit construction by introducing the world’s first Thermo-composite casing in 2011, followed by its innovative Bio-composite design made from recycled materials. These lightweight, thermally efficient casings represent a major advancement in sustainable and high-performance HVAC infrastructure.
