VFD Rentals
SAI offers rental VFD control panels. Models range in power from 10 HP to 250 HP, 3-Ph 480 Vac.
The rental units are based on SAI's DURA-Drive Type 3R panels. The VFD control panels are adapted for renting - making them easier to move, wire and operate.
Rentals are quoted on a weekly or monthly basis, portal-to-portal, with a minimum of one week rental. Rentals are EXW with pickup and drop-off at SAI, Tomball, TX.
For a rental VFD quote, call SAI on 281.516.3130 or email sales@saidrives.com
VFD Control Panel Features
Industrial VFD
The control panel includes a high-performance industrial VFD from Danfoss (Vacon NXP Series). The Drives are quoted normal duty / variable torque. If the application is a heavy duty / constant torque, the drive will need to be up sized to ensure sufficient power is available.
The VFD is suitable for a wide range of applications including pumps, compressors, mixers and conveyors.
Enclosure
The enclosure protection rating is Type 3R - "Rain proof and ice / sleet proof – indoors / outdoors" and is intended for general purpose outdoor use. The primary protection against falling rain.
The rating does not cover 'wash-down', meaning you should not use a direction-hose towards the enclosure.
Operating Temperature
The control panels are designed to operate within an ambient temperature range of -10C to 40C. The panel includes a thermostat to control fans for cooling and heating pads for warming.
Operators
The VFD panel includes operators for direct-process control. Run status indicators are also included for power and VFD status.
A HMI (LCD and keypad) is used for real-time monitoring including speed and amps. The keypad is used to make parameter changes.
Safety
Built to UL 508A standards.
Electrical Protection
Rental units include a surge protection device (SPD) to protect the equipment from transient voltages typically associated with lightning strikes or inrush from transformers.
Rental Features
The rental units have been prepared to make the rental experience as easy as possible.
Maneuvering Equipment
The small rental units (< 20 HP / FR4) have been welded to a portable dolly. The larger units have been mounted to a steel-tubed frame. The frame allows forklifts to move the equipment securely. The frame is crisscrossed providing forklift access from either side. This makes loading and unloading from freight vehicles easier.

Cable Junction Boxes
Cable junction boxes have been added to both sides of the control panel for quick connection to input supply and motor leads. The junction boxes can be secured from tampering with a padlock.

Security
The drive operators and HMI keypad are located under a pad-lockable door.
In addition to physical access, the VFD offers a secondary level of access control through pass-code lockouts. VFD operations can be restricted to different user pass-codes.

Remote Control
Terminal block is wired for default remote command.
Rental Process
Confirm VFD Requirements
To identify the appropriate VFD size, we need confirmation on the following: input voltage, phase, application, any communication or control logic customization, motor RPM, full load amps.
If the motor name plate is available please submit this as part of the requirements gathering process.
Start Date and Duration
During the initial quote development, we request the start date and estimated rental duration.
We request a minimum of 2 days visibility of a VFD rental in order to provide sufficient time to prepare and test the for drives for rent.
VFD Configuration
Every rental VFD is prepared and tested for the intended operational use case.
The VFD is programmed to the customer supplied motor name plate data. Any custom modifications are also implemented at this stage.
QA Check - Multi-point Inspection
Once the VFD is prepared, a QA check is performed which tests the electrical wiring, nut torque and applied motor load.
A copy of the inspection report is included with the drive rental.
Pickup / Drop-off
VFD rentals are quoted EX-works, so the the customer is responsible for pickup and drop-off.
To assist with delivery, SAI issues weights and dimensions of the rental units and confirm the date the drive is ready for collection.
Collection should be between 8.00 am to 4.30 pm CDT, Monday to Friday.
Rental Conditions
Transport
During transport the VFD rentals need to be protected from driving rain. They must either ship within a boxed truck or be tarped.
Liability
Equipment liability and responsibility transfers to the renter as soon as the equipment is loaded onto the freight vehicle and returned following an approved return inspection.
SAI will perform this inspection within 24hrs of the return.
We advise all renters to confirm they have sufficient equipment insurance to cover the full replacement cost of the VFD control panel. The estimated replacement cost is listed on the VFD rental quote.
If the unit is damaged, SAI will make an assessment of the damage and if repairable will proceed to do so. The rental remains open until such time as the rental repair is complete.
Signed Rental Terms & Conditions
A signed copy of SAI's full rental terms and conditions must be on file prior to the release of rental equipment. A copy of the rental terms and conditions is available
