POLISH PRODUCT LPHW unit heater FARMER HCF
FARMER HCF industrial LPHW unit heaters were designed for operation in aggressive environments typical of the agricultural sector — with a high concentration of dust, ammonia or acidic compounds. The unit has a durable EPP housing and corrosion-resistant components, including a heat exchanger coated with an epoxy coating. It performs well in facilities such as cowsheds, pig houses, stables or greenhouses. It can work with both hot and chilled water, providing heating and cooling functions.
About the product
FARMER HCF is an LPHW unit heater specially designed to operate in aggressive agricultural environments — cowsheds, pig houses, stables and greenhouses — where there is a high concentration of dust, ammonia and acidic compounds. It can work with both hot and chilled water, combining heating and cooling functions in a single unit.
Key components of the unit are corrosion-resistant: the copper-aluminium heat exchanger is protected with a GOLD epoxy coating, which protects against the effects of high humidity, ammonia and acidic vapours. Versions with an IP54 motor (3-stage AC) and a reinforced IP66 motor (1-stage AC) are available, allowing the unit to be matched to the severity of the environment. Heating capacity reaches 65,9 kW, and airflow up to 5000 m³/h.
The expanded polypropylene (EPP) housing provides excellent thermal and acoustic insulation at a low weight, and its high chemical and mechanical resistance simplifies transport, installation and servicing. Manually adjustable ABS air louvres — optionally with a 360° diffuser or confusor — allow the airflow direction to be precisely set.

Why choose the FARMER HCF unit heater?
Exceptional IP66 durability for aggressive agricultural environments
FARMER HCF was designed specifically for the difficult conditions found in agricultural facilities such as cowsheds, pig houses, greenhouses and other livestock buildings. The unit heater is characterised by exceptional corrosion resistance and high mechanical durability. Key components, including the heat exchanger coated with an epoxy coating, are resistant to dust, ammonia and acidic vapours. Thanks to the available motor options in an IP54 (3-stage) or reinforced IP66 (1-stage) version, the unit ensures reliable airflow performance and resistance even in the most demanding conditions.
Heat exchanger coated with GOLD epoxy
FARMER HCF is equipped with a heat exchanger made of copper and aluminium, protected with a GOLD epoxy coating, which provides the highest resistance to corrosion. This advanced solution protects the unit against the negative effects of high humidity, ammonia and acidic vapours, guaranteeing long and reliable operation in difficult agricultural conditions.
Light and durable EPP housing
The unit’s housing is made of expanded polypropylene, which provides excellent thermal and acoustic insulation while reducing the weight of the unit heater. This material is characterised by high chemical and mechanical resistance, which simplifies transport, installation and servicing of the unit.
Heating and cooling in one unit
FARMER HCF was designed to work with both hot and cold water as the working medium, enabling heating or cooling of rooms with a single unit.
Cooling mode and water vapour condensation
During operation in cooling mode, water vapour may condense on the surface of the unit. In such a case, the use of a dedicated drip tray, available for wall installation, is recommended. The tray should be connected to the condensate drainage system to ensure safe removal of water. To reduce excessive condensation, the water or air flow can be adjusted.
Precise air distribution thanks to adjustable louvres
FARMER HCF is equipped with manually adjustable ABS air louvres, which enable precise setting of the airflow direction. This flexibility allows the air distribution inside the facility to be optimised.
HC rotating mounting bracket
The HC rotating mounting bracket is a practical mounting element dedicated to LPHW unit heaters from the HC series. It allows the unit to be easily rotated horizontally, making it possible to precisely adjust the airflow direction to the current needs of users and the layout of the room.
The bracket also simplifies installation and servicing of the unit heater.

Yes. It's enough for the heat exchanger to be supplied with chilled water. Cooling efficiency depends on the supply water temperature and the inlet air temperature. Due to the possibility of condensate forming, a drip tray must be used. Operation of the unit in cooling mode is only possible with wall mounting of the unit heater — with ceiling mounting, the condensate would not be caught by the tray.
Yes, it can. Depending on requirements, a confusor (to increase jet reach) or a 360° diffuser (to shorten the jet, but achieve better mixing with the surrounding air) can additionally be fitted to the outlet.
Yes, our unit heaters are compatible with heat pumps.
No. Unit heaters can be supplied with water or a glycol solution at the appropriate pressure. Water pressure that is too low may negatively affect the heating capacity of the unit heaters.
Check the connection to the electrical installation and make sure the unit heater is connected to the mains in accordance with the wiring diagrams provided.
