The low-temperature modulating helical fan coil
The exclusive new “LT” (Low Temperature) range of Comex Group has been designed for winter and summer climate control in line with the new energy efficiency regulations. This high-efficiency range is designed for supply with very low-temperature hot water, down to 38°C, integrating the requirements of the European ErP Directive.
Available in 18 models, the Aerotermo LT has an IP 44, IP 54 electrical protection rating and a < 10 micron filter (optional for the purification of suspended dust), which allows it to meet the environmental compliance requirements for any type of activity.
Why is the AEROTERMO LT fan coil an ideal solution?
1 BECAUSE IT IS THE IDEAL PRODUCT TO COMBINE WITH HEAT PUMP
2 BECAUSE IT IS THE ONLY ONE WITH THE PATENTED YOUSAN SANITISATION SYSTEM
3 BECAUSE IT OPTIMISES THE PERFORMANCE OF CONDENSING BOILERS
4 BECAUSE IT IS IDEAL FOR VERY LOW TEMPERATURE HEAT SOURCES
5 BECAUSE IT IS GREEN AND USES RECYCLABLE COMPONENTS
6 BECAUSE IT HAS A 10-YEAR WARRANTY

CHARACTERISTICS
AEROTERMO LT fan coli unit have been specially designed to operate with hot water at low temperatures, even up to 38°C, in order to significantly reduce the stratification effect of the air.
With AEROTERMO LT fan coli unit, the supply of hot air into the room is managed by a microprocessor which, based on defined parameters such as room temperature, supply air temperature and supply water temperature, determines the operating logic for heating/cooling the room with maximum comfort and energy saving.
