Elta Quietflow Twin SQT250-1ECL

Each unit is acoustically lined internally with Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining minimising breakout noise levels.
New Multi-mount brackets allow easy mounting in a range of orientations.
Integrated commissioning control allowing single speed selection and also limiting maximum speed if used with an external potentiometer.
High efficiency low tonal noise backward curved centrifugal impellers are directly driven by EC external rotor motors, provide low specific fan powers and stepless speed control without tonal noise generation.
Units can be weatherproofed in the factory to allow external installation.
EC motors providing precise speed control via potentiometer, BMS or Elta Fans DCV control. Reduced fan speeds can provide significant cost-savings through lower energy consumption in both mechanical energy of motors and also on the conditioning of replacement air.
Twin Fan Operation
Allowing control for auto changeover and duty share.
Each SQT has a 12 month warranty.
The robust 1.2mm galvanised mild steel sheet casing, is treated internally with a Class O rated (BS 476 Parts 6 and 7) fire resistant acoustic foam lining with a fire resistant polymeric coating. The wrap around folded casing is specially manufactured using integral motormounting plates to provide additional rigidity for the casings. Each casing provides spigots to suit standard circular ducting. A removable lid is provided as a standard feature to facilitate ease of maintenance and cleaning.
The twin range of units have an EC external rotor motor fitted as standard. The motor contains sealed for life bearings. Thermal Class of motors to THCL 130 or 155 dependent on size. All motors are suitable for use in ambient air conditions up to +60 ℃. Electrical connection shall be via an IP55 terminal box mounted on the side for easy customer connection.
High efficiency low tonal noise backward curved centrifugal impeller, dynamically balanced to ISO 14694 Grade G6.3 and directly driven by the motor to provide a smooth airflow through the unit.
Units shall be supplied with integrated commissioning control allowing single speed selection and also limiting maximum speed if used with an external potentiometer. Speed control shall be via external potentiometer or0-10V, Auto changeover in the event of fan fail or duty share of run and standby fan shall be via auto changeover panel which is an optional extra.
Units are to be designed and manufactured with procedures as defined in BS EN ISO 9001. All Quietflow SQT units are to be tested to ISO 5801 (airside performance) and BS 848 Part 2 (sound performance).
