CONDENSERS

Electronically Commutated (EC) Fan Motor

Sickle bladed fan assemblies with integral long bellmouth and fingerproof grille. Incorporates external EC rotor motor

technology to provide highly accurate discreet speed control. The fans offer maximum airflow performance while

keeping sound levels to a minimum.

Each fan incorporates electronically commutated DC motor control using semi-conductor modules responding to a

signal from the Airedale indoor unit.

EC motors are DC motors with integrated ac to DC conversion; this gives the flexibility of connecting to ac mains with

the efficiency and simple speed control of a DC motor. The EC fan offers significant power reduction in comparison

with equivalent ac fan at both full and modulated fan speeds. The inbuilt EC fan control module allows for fan speed

modulation from 15-100%, the modulating range of a standard ac fan is typically 40-100% of full fan speed.

IMPORTANT

All fans are supplied pre-programmed to a head pressure setpoint of 26 barg and proportional band setpoint of 6 barg.

For alternative settings, please specify at order.

Short Case Axial Fans

Short case axial fans can be supplied for indoor installations where discharge air requires to be ducted to an outdoor

location. The fans will meet duty plus 75Pa of external static pressure.

Head pressure control is maintained by a modulating fan speed controller fitted to the outdoor unit. The controller is

rated to IP54 for outdoor use and will operate accurately in ambient temperatures down to a minimum of -20°C.

Corrosion Resistant Coated Coils

For aggressive atmospheres a corrosion resistant coating can be applied to the aluminium fins.

Head Pressure Control

(On / Off)

Head pressure control is maintained via a factory fitted on/off pressure switch rated to IP54 for outdoor

use as standard. Good control with ambients down to 0°C, below this temperature variable speed controllers are

recommended.

The head pressure is factory set to 26 barg (377 psig).

Shut Off Valves

Where unit isolation for easier maintenance is required, shut off valves can be supplied loose for on site fitment.

Coil Guards

Protective mesh guards can be fitted to each of the outer coils to protect against damage.
