use of a basic model identified in paragraph 1 for compliance, marketing, or other purposes unless that basic model has been tested in accordance with the provisions set forth above and such representations fairly disclose the results of such testing.
4 This Interim Waiver Order shall remain in effect according to the provisions of 10 CFR 431.401.
5 This Interim Waiver Order is issued on the condition that the door performance characteristics, statements, representations, test data, and documentary materials provided by Hercules are valid. If Hercules makes any modifications to the controls or configurations of a basic model subject to this Interim Waiver Order, such modifications will render the waiver invalid with respect to that basic model, and Hercules will either be required to use the current Federal test method or submit a new application for a test procedure waiver. DOE may rescind or modify this waiver at any time if it determines the factual basis underlying the petition for the Interim Waiver Order is incorrect, or the results from the alternate test procedure are unrepresentative of the basic models true energy consumption characteristics.
10 CFR 431.401k1. Likewise, Hercules may request that DOE rescind or modify the Interim Waiver Order if Hercules discovers an error in the information provided to DOE as part of its petition, determines that the interim waiver is no longer needed, or for other appropriate reasons. 10 CFR
431.401k2.
6 Issuance of this Interim Waiver Order does not release Hercules from the applicable requirements set forth at 10 CFR part 429.
DOE makes decisions on waivers and interim waivers for only those basic models specifically set out in the petition, not future models that may be manufactured by the petitioner.
Hercules may submit a new or amended petition for waiver and request for grant of interim waiver, as appropriate, for additional basic models of walk-in doors. Alternatively, if appropriate, Hercules may request that DOE extend the scope of a waiver or an interim waiver to include additional basic models employing the same technology as the basic models set forth in the original petition consistent with 10 CFR
431.401g.
Signed in Washington, DC, on December 28, 2020.

Petition for Hercules for Waiver of Test Procedure for Walk in Cooler and Freezer Doors Hercules, a Senneca Holdings company, is petitioning for a Waiver and submitting an Application for Interim Waiver from the current Department of Energy DOE code for walk in freezer doors per Title 10
Chapter II Subpart R, General Provisions, Section 431.401.
Hercules began operating in 1952 as an insulated walk-in cooler and specialty refrigeration equipment manufacturer. Today, Hercules is a recognized manufacturer of highquality, made-to-order Cold Storage door systems. Hercules is mainly focused on applications including Blast Freezer, Freezer, Cooler, Docks, Processing, Ripening Rooms, Automotive Test Cells, Research Facilities and Distribution Facilities.
Senneca Holdings Company previously sold Hercules products into applications greater than 3000 square feet, but recently has decided to market Hercules products into smaller applications that are regulated by DOE.
I. Basic Models for Which Hercules Requests a Waiver Hercules requests a waiver and interim waiver for the Hercules brand basic models set forth in Appendix I.
Please note that Appendix I uses wildcards to represent height and width measurements in the individual model numbers, as well as whether the individual model includes a window.
Use of the wildcards is necessary as Senneca has not yet determined every precise height and width combination that we will include in a forthcoming certification submission. In order to ensure DOE has enough information to assess what sized doors are covered by the waiver request, Senneca has identified the final surface area for each basic model listed in Appendix I. The ultimate size of a door is determined by the surface area in the basic model number, however no door covered by Appendix I has an opening larger than 288 inches or smaller than 36 inches.
The exact height and width of individual models will be reflected in Sennecas certifications.
II. Why Hercules Requests a Waiver Currently, per the standard at 10 CFR
431.306, section 4.5.2, the rating of the door for insulating values and motor power uses a percent time off, or PTO, of 25 percent. This would require the door motor to operate for 75 percent of the day which significantly overstates

normal motor usage on our basic brands of powered door models.
The first example, listed below, discusses two door types within our horizontally sliding door model groups that normally operate at a total speed of 10 Inches Per Second IPS or greater.
The second example is for the Hercules vertical lift door model that normally operates at a total speed of 12 IPS or greater. Documentation and support for the numbers used below are included in Appendix II. While the supporting materials in Appendix II refer to and cover a broader group of doors than the Hercules basic models listed in Appendix I, these materials are accurate in their description of the components of the Hercules basic models listed in Appendix I. That is, the supporting materials provided cover all Hercules basic models listed in Appendix I.
A. First Example: Hercules Horizontally Sliding Door Models Hercules Listed Model Groups:
EHSDSingle Slide Electric Horizontal Sliding Door EBPDBi-Parting Electric Horizontal Sliding Door EHSD doors have one panel that must travel the entire width of the opening to open or close, while EBPD
doors have two panels that each must travel one-half the width of the openingfrom the midpoint of the openingto open or close. As a result, although the operator moves both EHS
D and EBPD door panels at the same speed, the door cycle for EBPD doors is half that of EHSD doors. For this reason, the PTO values for EHSD
versus EBPD doors are calculated separately below.
The DOE has stated that door operation of 120 cycles operations per day is normal. Hercules uses this cycle number as our norm when estimating customer usage of sliding model groups listed above also and will use this as the base for our first PTO example. One cycle is defined as one opening and closing cycle of a door with a door opening of 288 inches operating at a constant speed of 10 IPS in both opening and closing directions.
The amount of time that the door is in the open and stopped position does not add to the calculation as the motor is not powered during this time.
EHSDSingle-Slide Electric Horizontal Sliding Door:
Door Cycles/Day = 120
Door Cycle time = 57.6 Sec.
Total run time/Day min. = 115.2
Total run time/Day hr. = 1.92
Total not running time/Day hr. = 22.08
PTO calculated = .92
