PRODUCT OVERVIEW

Floor Standing Cabinet Heater up to 600kW

The Hadar Zephr is a cabinet heater that combines innovative design with advanced heat exchanger technology to deliver high efficiency, cost-effectiveness, and durability. Available for Natural Gas, LPG, oil, or Hydrotreated Vegetable Oil (HVO) fuel, it provides flexible fuel choice to suit different site conditions and environmental preferences. Standard outputs range from 30 kW to 300 kW, with higher outputs up to 600 kW available upon request for the largest commercial and industrial buildings.

​

The Zephr is available in condensing models achieving 101% efficiency and non-condensing models at 93.5% efficiency, providing options to match different efficiency requirements and budgets. At the core of each unit is a 304 grade stainless steel heat exchanger and combustion chamber, ensuring long-term durability and excellent corrosion resistance.

​

The cabinet format is a self-contained, floor-standing design that houses all components within a single enclosure. This makes the Zephr a practical choice for plant room installations or for positioning directly within the space being heated, offering a neat, contained heating solution that does not require wall or ceiling mounting.
