FAQs
The CTM1764T uses a standard 286T frame with a foot-mounted base for straightforward mounting. Confirm the motor base dimensions align with your chiller or cooling tower footprint, ensure ample clearance for torque and service access, and wire per standard 460 V 3-phase, 60 Hz mains. Pre-wire with DOL starter capability to simplify commissioning and minimize lead times.
The motor offers two speeds: 1760 rpm at the higher setting and 870 rpm at the low setting. The horsepower rating is 30 HP at the high speed and 7.5 HP at the low speed, with a service factor of 1.15. This enables efficient operation across load conditions typical of chillers and cooling towers.
Yes. The CTM1764T is specifically designed for chiller/cooling tower duty with a 286T frame, TEFC enclosure, and 460 V, 60 Hz power. Its two-speed capability delivers energy efficiency for variable cooling loads, while the rugged construction supports long service life in demanding industrial HVAC environments.
The CTM1764T carries CSA and UR safety listings and adheres to NEMA standards, confirming regulatory compliance for North American installations. This helps with system approvals, reduces risk during commissioning, and supports safer maintenance practices in regulated facilities.
With a TEFC enclosure and robust bearings (6311 ball bearings) designed for long life, maintenance intervals are minimized. The two-speed operation reduces energy consumption under partial load, contributing to lower operating costs and faster payback in cooling applications. Stock availability across warehouses further reduces downtime and maintenance lead times.
