Drive control panel
Recently extended to 600 v, the ACH550 ac-drive line features a new control panel that is similar in look, feel, and functionality to a mobile phone. The panel features two soft keys, the functions of which change according to the operating state of the panel. A built-in help button and real-time clock enable fast setup, simple configuration, and rapid fault diagnosis, while built-in Start-up Assistant software ensures quick startup and tuning. The panel asks users for motor nominal values, the I/O configuration, and application-specific parameters (acceleration and deceleration). An online information system offers additional help at every step. The real-time clock logs the date and time of faults and all important operating data. If a fault occurs, Diagnostic Assistant will suggest ways to fix it. The panel monitors energy consumption, running hours, or motor revolutions. Users can set their own limits for one of these parameters so that the drive gives an alarm whenever the limits are reached. The keypad then will indicate when the drive, motor, or driven equipment should receive preventive maintenance.
PTAC-sleeve repair kit
With FIXAsleeve, cracked fiber-glass PTAC sleeves can be repaired in 10 min. A 12-in.-by-½in. aluminum “C” bracket snaps onto the edge of a sleeve. A 12-in.-by¾-in. “J” bracket then snaps over the “C” bracket and is screwed into the side of the sleeve with two stainless-steel screws, providing enough strength to withstand hurricane-force winds. FIXAsleeve also is available for steel sleeves.

Large-capacity industrial water chiller
Introduced during the mid-1960s, but absent from the market for six years, the reintroduced 17DA industrial water chiller provides capacity performance in the nominal 3,000-, 4,000-, and 5,000-ton range and uses HFC-134a refrigerant. A steam turbine, electric motor, or gas engine drive can be selected to match the most economical fuel available.
