With enhanced capabilities, the 300 model offers improved heating distribution, making it ideal for warehouses and production floors. The ease of installation and maintenance further enhances its appeal, allowing businesses to focus on their operations rather than on complicated heating systems.

The Roberts Gorden 400 is a powerhouse in the lineup, engineered for larger spaces that demand high-performance heating. Its robust construction and powerful output provide effective warmth even in challenging environments. The unit is equipped with sophisticated controls that promote energy efficiency while maintaining optimum comfort levels.

In the mid-range spectrum, the Roberts Gorden 150 and 225 models cater to businesses needing versatile heating solutions. Both models are designed with user-friendly interfaces and include safety features that comply with industry standards. Their lightweight design allows for easy installation and mobility, making them suitable for temporary or permanent heating applications.

Overall, Roberts Gorden's commitment to innovation and efficiency is evident across its product range.
