LPHW Unit Heater HC-EC
The HC-EC LPHW unit heater is designed for heating and cooling air in industrial and commercial facilities, such as production halls, warehouses, workshops and service rooms. It requires connection to a water system with a heating medium, which transfers heat through the heat exchanger into the heated space. It can also be supplied with chilled water to circulate and cool the air in the facility. The unit combines high performance with energy-efficient EC motor technology and is fully compatible with heat pumps, ensuring efficient heating and cooling.
About the product
HC-EC is an LPHW unit heater in an energy-efficient version with an EC motor, designed for heating and cooling industrial and commercial facilities — production halls, warehouses, workshops and service premises. It requires connection to a water installation with heating medium, but can also be supplied with cold water to circulate and cool air, making it fully compatible with heat pumps in both operating modes.
The energy-efficient EC motor with IP54 protection and smooth speed control in the range of 0–100% provides better fan operation control and lower energy consumption than conventional motors. Airflow up to 4,800 m³/h and heating capacity from 1.97 to 88.9 kW allow the unit to be matched to facility requirements.
The copper-aluminium heat exchanger, available in 1-, 2- or 3-row versions, operates with a medium temperature up to 120°C. 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 dirmuchu.

Why choose the HC-EC unit heater?
Energy-efficient EC motor with smooth 0–100% speed control
The HC-EC LPHW unit heater is equipped with an energy-efficient EC motor with IP54 protection that enables smooth fan speed control in the range of 0% to 100%. This means better fan speed control and lower energy consumption compared to conventional motors.
With airflow up to 4,800 m³/h (depending on model), HC-EC is an excellent choice for spaces where better fan speed control and lower energy consumption are key priorities.
Lightweight and durable EPP housing
The HC-EC 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.
Copper-aluminium heat exchanger
The copper-aluminium heat exchanger provides efficient heat transfer in heating mode. It also allows operation in cooling mode when connected to chilled water. Depending on the model, 1-, 2- or 3-row exchanger versions are available. The exchanger is designed for operation with heating medium at a maximum temperature of 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.

Every HC-EC unit heater is equipped with adjustable ABS air louvres for precise setting of airflow direction. Where even air distribution or extended reach is required, the unit can optionally be fitted with a 360° diffuser or confusor.
Cicha i kompaktowa nagrzewnica HC15-EC
HC15-EC is a quiet and compact unit, ideal for smaller spaces. The unit heater has an EPP housing making it lightweight and easy to install. It delivers reliable operation and low energy consumption.
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.
