  • PT - heating capacity
  • Tp1 - air temperature at the unit inlet
  • Tp2 - air temperature at the unit outlet
  • Tw1 - heating medium temperature at the heat exchanger inlet
  • Tw2 - heating medium temperature at the heat exchanger outlet
  • Qw - heating medium flow rate in heat exchanger
  • Δpw - heating medium pressure drop in heat exchanger

If you want to calculate heating capacity at different parameters you can do this at manufacturer website.

LEO AGRO fan heaters are specially designed for aggressive conditions and well-suited for heating of large areas where dust, high humidity and chemicals based corrosive exposure is present, e.g. poultry, pig, cattle and stud farms, washing and drying sites, waste water treatment areas, etc. LEO AGRO heaters are non-inertial: high capacity enables fast and uniform heating of premises; safe and easy to clean. LEO AGRO fan heaters are manufactured of three different casings: 1) metal casing, 2) plastic casing and 3) openable casing.

LEO AGRO NEW fan heater1) LEO AGRO ST metal casing is made of zinc steel coated with anticorrosive layer, resistant to abrasion, heat, cold, corrosion and weather conditions. Specific heat exchanger is epoxy and special anticorrosive layer coated. Larger gaps between heating fins (4 mm) as well as thicker heating fins make easy cleaning of impurities with high pressure washing equipment. Washing process causes no deformation to heating fins, and drain plugs installed at the top and bottom of heater casing provide easy removal of water accumulated in the casing. LEO AGRO heaters are recommended to use in large areas of high ammonia concentration (up to 25 ppm), high air dust and humidity level: in chicken farms, sawmills, car wash sites, pools.

LEO AGRO CR fan heater2) LEO AGRO CR – plastic casing, heat exchanger is anticorosive layer coated. It has thicker heating fins with larger gaps between them (4 mm). Most suitable for high humidity and average pollution premises, such as: car washes, swimming pools, greenhouses. It can be washed with high pressure washing equipment.

LEO AGRO HP SP fan heater3) Key advantage of LEO AGRO SP and HP is easy-to-open casing which ensures easy access to heat exchanger for cleaning from both sides. Fan in LEO AGRO SP and HP models is located in the front part of the heater, and it directs heat from heat exchanger to the premises at the distance of 28 m.
SP model heat exchangers are epoxy coated; they are designed for aggressive environment such as poultry farms and drying sites. SP models as standard LEO AGRO ones can be applied in areas of high ammonia concentration (up to 25 ppm).
HP model heat exchangers are coated with several layers of special anticorrosive paint and are designed for heating of EXTREMELY severe areas: pig farms and waste water treatment areas. Heaters are resistant to major corrosive compounds; they also can be cleaned by pressurized air or flushed by high pressure washing equipment.

All LEO AGRO models are equipped with IP66 protection class fans with thickened plastic blades which are more wear-resistant. Fan design allows the increasing loads (e.g. exchanger contamination with dust) to effect its performance as less as possible.

The advantages of LEO AGRO fan heaters:

  • Heaters are developed and produced by company FLOWAIR. This company specializes in production of such type of heaters only and is the number one in a competitive Polish market!
  • Designed for aggressive environment, agriculture – high quality parts, resistance to chemical exposure, humidity, dust and corrosion.
  • IP66 fan. Such fans with thickened plastic blades are suitable in the areas full of dust or humidity.
  • Easy to clean – heater dismantling is not needed; it can be cleaned by pressurized air or water. Larger gaps between heat exchanger fins which are thickened to prevent deformation when cleaning.
  • Quality guarantee – European product with technical properties meeting the declared values, CE certified.
  • Easy to install. Light weight and specific mounting brackets make LEO AGRO fan heaters easy to install.
  • Extensive application: poultry, pig, cattle and stud farms, slaughterhouses, sawmills, car wash sites, greenhouses, pools, drying sites, waste water treatment areas and other facilities with potential air pollution and high humidity.
