Seismic Qualification for Ground and Roof Level ApplicationsSquare D E-Flex enclosed drive controllers are designed to withstand harsh environments and meet the 2003 IBC and ASCE 7 standards for seismic qualification in accordance with ICC ES AC156 testing protocol.

E-Flex enclosed drive controllers were subjected to actual shaker table tests for seismic ratings, not just theoretical anchorage and bolt-hole calculations. When mounted in accordance with published guidelines, the E-Flex drive enclosure is designed and constructed to withstand violent transfer of both vertical and transverse axial vibration loads. This means that these controllers have structural integrity and can be specified with the assurance that it can continue to keep a facility running smoothly after a seismic event.

Enclosure StylesSquare D E-Flex enclosed drive controllers can meet both indoor and outdoor application requirements with Type 1, Type 12/12K and Type 3R enclosures.

n Type 1 enclosures are designed specifically for indoor, non-dusty environments

n Type 12/12K enclosures are designed for protection from dust and dripping liquid

n Type 3R enclosures permit installation on rooftops or other outdoor locations to free up space in mechanical equipment rooms. Plus, Type 3R enclosures allow operations in temperature ranges from +14˚ to +122˚F (-10˚C to +50˚C)

Industrial-grade reliability designed for HVAC

Square D®E-Flex™ AC drives provide the optimum combination of efficiency and economy for HVAC, pump and fan applications in both commercial and industrial environments. They are the ideal choice in adjustable speed drive solutions for applications such as:

n Air Handling Units

n Supply and Return Fans

n Exhaust Fans

n Chilled Water Pumps

n Hot Water Pumps

n Cooling Tower Fans and Pumps

An Example of an Energy Saving Calculation*A fan with a 20 horsepower motor supplies air 10 hours a day for 260 days a year and the energy cost is of $0.10 cents per kilowatt-hour.

Cost of running full speed:

20 hp x 0.746 kW/hp x 2600 hours x $0.10/kWhr = $3879.20

Assuming the fan does not need to run at full speed all of the time, let’s use an example of:

n Running full speed (100%) for 25% of the time n 80% speed for 50% of the timen 60% speed for the remaining 25% of the time

Cost of running with an AC drive controlling the motor:

20 hp x (1)3 x 0.746 kW/hp x 650 hours x $0.10/kWhr = $969.8020 hp x (0.8)3 x 0.746 kW/hp x 1300 hours x $0.10/kWhr = $993.0820 hp x (0.6)3 x 0.746 kW/hp x 650 hours x $0.10/kWhr = $209.48

Total = $2172.36

Annual savings: $�879.�0 - $�17�.�6 = $1706.84

n In many instances, the payback period for using an adjustable frequency drive in place of other flow control methods is less than 18 months.

Actual results may vary for closed loop pumping and variable air volume systems.

Energy EfficiencySquare D E-Flex enclosed drive controllers can increase system energy efficiency by providing a means to reduce the motor speed of HVAC equipment based on the needs of the building environment (Lower motor speed = Lower energy costs).

Energy Savings can be realized because of the Affinity laws of physics:

n Flow = f (motor speed)

n Pressure = f (motor speed)2

n Horsepower = f (motor speed)3

A motor running at 50% of full speed capacity has a motor torque of 25% of full speed and the electricity required to operate the motor at 50% of full speed is at 12.5%. Thus, reducing motor speed can significantly reduce the electrical energy consumption.
