LPHW Unit Heater HC3P
The HC3P three-phase LPHW unit heater is designed for heating large spaces such as industrial halls, warehouses and retail facilities. Equipped with a three-phase motor, it provides efficient heat distribution. The unit requires connection to a system with a heating medium, which transfers heat through the heat exchanger into the heated room. It can also operate with cold water to support air circulation and cooling.
About the product
HC3P is an LPHW unit heater in a three-phase version, designed for heating large high-volume spaces — industrial halls, warehouses and commercial facilities. It requires connection to an installation with heating medium, but can also work with cold water to support air circulation and cooling in the facility.
The distinguishing feature of the unit is its single-stage, three-phase AC induction motor (400 V) with IP54 protection rating, which ensures reliable operation and high durability where constant air circulation is required. Heating capacity from 2.36 to 80.1 kW and airflow from 2,500 to 4,000 m³/h allow the unit to be matched to the needs of a large facility.
The copper-aluminium heat exchanger, available in 1-, 2- or 3-row versions, operates with a medium temperature up to 120°C and enables both heating and cooling. The expanded polypropylene (EPP) housing is lightweight, resistant to mechanical damage and provides excellent thermal and acoustic insulation, while adjustable ABS air louvres — optionally with a 360° diffuser or confusor — allow precise setting of the airflow direction.

Why choose the HC3P unit heater?
Reliable three-phase AC induction motor with IP54 protection
HC3P is the only LPHW unit heater equipped with a single-stage, three-phase AC induction motor (400 V) with IP54 protection rating.
The three-phase motor provides reliable operation and high durability in large-volume industrial facilities where constant air circulation is required. The unit is equipped with a single-stage fan.
Lightweight and durable EPP housing
The HC3P LPHW unit heater has a housing made of expanded polypropylene, a lightweight material resistant to mechanical damage that also provides excellent thermal and acoustic insulation. This housing guarantees durability in demanding industrial environments and facilitates installation thanks to its low weight.
Heat exchanger for heating and cooling
At the heart of the HC3P unit heater is a copper-aluminium heat exchanger designed for efficient heat transfer or cooling depending on the temperature of the heating medium or water. Depending on the model and design requirements, single-row, double-row or triple-row exchanger versions are available. The exchanger is designed for operation with heating medium at temperatures up to 120°C.
Cooling mode and water vapour condensation
During cooling mode operation, water vapour may condense on the unit surface. To effectively drain condensate, the use of a dedicated drip tray is recommended.
The tray is compatible with wall mounting and should be connected to the drainage system for safe removal of collected water.
Regulowane kierownice powietrza do precyzyjnej kontroli kierunku nadmuchu
Every HC3P LPHW unit heater is equipped with manually adjustable ABS air louvres for precise setting of airflow direction. Depending on requirements, a 360° diffuser or confusor can be used for even air distribution.
Dedicated HC rotating bracket
The HC rotating bracket is a practical mounting accessory dedicated to HC series LPHW unit heaters. It enables easy horizontal rotation of the unit, allowing the airflow direction to be precisely adjusted to the current needs of the users and the room layout.
The bracket also facilitates installation and servicing of the unit heater.

FAQ
Yes. It simply needs to be supplied with chilled water. Cooling efficiency depends on the supply water temperature and the air inlet temperature. Due to the possibility of condensate forming, a drip tray must be used. Cooling operation is only possible when the unit heater is wall-mounted — when ceiling-mounted, the condensate would not be caught by the drip tray.
Yes, it can. Depending on requirements, a confusor (extends jet reach) or a 360° diffuser (shortens jet reach but gives better mixing with 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 glycol solution at appropriate pressure. Excessively low water pressure can negatively affect unit heater heating capacity.
Check the electrical installation connection and make sure the unit heater is connected to the supply in accordance with the wiring diagrams provided.
