The LEO HD fan heater is designed for building structures that require equipment with increased resistance to environmental conditions. The water heat exchanger installed in the heater is covered with special pigmented polyurethane coating PoluAl XT Blygold, which is characterised by very high resistance to corrosion and chemical compounds.
The full range of LEO HD heaters means, above all, the opportunity to select the perfect solution for the facility's needs, because LEO HD have 10 heater models with a wide range of heating power. LEO HD can be available in two casing versions: EPP and INOX (casing made of acid-resistant steel AISI316L).
The LEO HD water heater can operate as a stand-alone unit and as part of the intelligent FLOWAIR SYSTEM. The T-box controller with touchscreen display, which is the brain of the SYSTEM, also controls multiple devices from one place

A specially designed console allows the device to be mounted vertically on narrow columns and partitions. When mounted vertically to the device, it enables parallel installation at various angles to the wall. With the use of dedicated ceiling-mount brackets, overhead installation is possible. INOX console included.
10 models available with 3 types of motors AC, EC and IP66. Allows for perfect match to the clients requirements.
Application
LEO HD fan heater for special purposes: car washes, waste treatment plants, food processing plants, hothouses, industrial environments or maritime facilities.
Device types available
- LEO HD AC IP54 – fan heater with AC fan
- LEO HD EC IP54 – fan heater with EC fan
- LEO HD AC IP66 – fan heater with AC fan with higher protection level IP66
All available models can be manufactured in one of two types of casings: expanded polypropylene (EPP) or stainless steel INOX AISI316L.
BLYGOLD heat exchanger
Standard heat exchangers are vulnerable to intense corrosion due to the nature of their design, which often involves different metals with incompatible chemical properties. The combination
of these metals can cause galvanic corrosion, especially when they are exposed to moisture and other substances. In addition, heat exchangers are often placed in environments featuring contaminated air, which can accelerate the corrosion process through chemical reactions.
The Blygold coating, as used in LEO HD, is an effective solution that provides lasting corrosion protection for heat exchangers, while maintaining heat transfer efficiency and minimal impact on pressure drop.
Design of LEO HD
Thanks to its clever design and the Blygold coating used on the exchangers, the LEO HD device is ideal for special purpose buildings.
Wide range of installation options
Allows easy installation at different angles to vertical and horizontal partitions.
