The S&P ILHB-ILHT ECOWATT models come in two types:

• ILHT CC ECOWATT: fan with multidirectional inlet plenum, motor shaft horizontal or vertical
• ILHT MV ECOWATT: ventilation unit only, motor shaft horizontal or vertical.

Construction consists of:

• Panels made of galvanized sheet steel;
• Modular structure in aluminum profiles;
• 4 mounting brackets;
• Rectangular duct couplings;
• Direct drive centrifugal backward curved impeller manufactured from galvanized sheet steel;
• Full access for cleaning and maintenance without dismantling the fan from the duct system;
• External control fitted and wired;
• Thermal protections integrated;
• Fault relay integrated;
• Fan speed/set point adjustable with the potentiometer placed in the control or with an external control type REB ECOWATT;
• Analogical input to control the fan with 0-10V input signal;
• Modbus RTU to RS485 port;
• ON-OFF electrical isolation switch;

The ILHB/ILHT ECOWATT are approved for extraction of hot gases and smokes in case of fire. This operation mode is automatic and does not require any parameterization: in case of extraction of hot gas at a temperature higher than 200°C, the control automatically switches to high speed and inhibits the internal thermal protections. The emergency operation mode can also be activated manually with a BDRA control box (accessory). CAV / VAV / COP models are deactivated. Each of the three versions has different characteristics. The VAV version has a variable air volume, while the COP version maintains constant pressure, and the CAV version provides a constant airflow rate with an airflow display.

The ILHB/ILHT ECOWATT can be installed in any position and connected from any side. Electrical supply is single-phase 230V 50/60 Hz for models 355, 400 and 450 and three-phase supply 400V 50/60Hz for models 500, 630 and 710.

Оn request, a reinforced sealing with grease resistant seal can be added specifically for kitchen applications, as well as a condensate drain, which is provided not mounted. Optional two-speed motors can be installed, which are not compliant with ErP. Displays for the VAV and CAV versions are provided separately.
