This test is to be taken in conjunction with our 2-½ hour webinar Managing Energy in Ventilation Systems: Variable Frequency Drives (VFDs). Webinar attendees who have paid for the test with registration should have received a copy of the test and do not need to purchase this downloadable test. Webinar attendees who viewed the webinar with a registrant, but did not themselves register, may receive a certificate of completion by purchasing this test and completing it and its evaluation and sending it to ACGIH® within the allotted time.
