Armstrong IVS Sensorless Pumps

Our HVAC market is recognized as “variable speed for part load”

Today’s expectation is that energy can be saved with equipment supplied for variable speed. VFDs are more reliable than mechanical switchgear and becoming as cost economic. A great deal of benefit is gained from an integrated approach to determining how that VFD is controlled for its connected HVAC system load.

To this point, S.A. Armstrong Ltd. has developed an integrated range of pumping systems from which system designers can choose the Design Envelope that serves the system needs providing:

• Full and part load efficient and controllable operation as the system requires
• Design range to satisfy initial design and leave a safety margin for design changes during construction and beyond

The Armstrong IVS Sensorless Pumps well beyond the competition including . . .

• Single unit pumping, and speed control. Just pipe, wire and start!
• Reduced installation and operating costs offer tremendous ROI and payback rates
• Flexibility for ever changing design and installation parameters, ideal for the retrofit market and new installations alike
• Standard 4300 or 4302 series unit -  no motor or drive removal necessary for seal service
• dualARM provides two-pump operation in a single pipe
• Motors will not overload – Controls allow max motor nameplate current only
• Supplied with 208V, 230V, 380V, 460V or 575V, ODP or TEFC motors
