Hoods and Enclosures Auto Sash Controller

Auto Sash Operator and Controller

TEL's innovative fume hood auto sash controller can be retrofitted to any fume hood and control system to maximize energy savings and provide increased safety for the operator. The auto sash controller is designed to close the sash of vertically rising sash fume hoods automatically when the operator is not present in front of the fume hood. A passive infrared sensor (PIR) constantly monitors the work area in front of the fume hood. If a person is not detected and the sash opening is clear, the sash will automati- cally close after a predetermined time. When the operator is present, the sash can be operated manu- ally via the optional Tiptronic touch pad. Auto-open option is also available. A dual auto sash controller is also available to operate fume hoods with two sashes including walk-in type, back-to-back type and side-by-side type sashes.

Features include: • Auto Close • Auto Open (user selectable - enabled/dis- abled/auto open if auto closed only) • Tiptronic Open/Close - touch sensitive sash movement (menu selectable) • Manual sash operation • Keypad Pushbutton Open/Close • Mute Audible Alarm Button • Inputs to BMS from Sash closer: - External Alarm Sounder Output
