5Legislative Language For Walk-in Coolers and
Freezers Amend the Energy Policy and
Conservation Act as follows 6313.
Standards (b Section 342 of the
Energy Policy and Conservation Act (42 U.S.C.
6313) is amended by adding at the end the
following (f) Walk-In Coolers and Freezers
Each walk-in cooler or freezer manufactured on or
after January 1, 2009 shall meet the requirements
in paragraphs (1) and (2). "(1) Walk-in
coolers and walk-in freezers shall meet the
following specifications (A) Have
automatic door closers that firmly close all
reach-in doors. Have automatic door closers that
firmly close all walk-in doors that
have been closed to within one inch of full
closure. This requirement does not apply to
doors wider than 3 feet 9 inches or
taller than 7 feet. (B) All walk-in freezers
shall have strip doors, spring hinged doors or
other method of minimizing infiltration when
doors are open. (C) Contain wall, ceiling
and door insulation of at least R-25 for coolers
and R-32 for freezers. Door insulation
requirements do not apply to glazed portions of
doors, nor to structural members. (D) Contain
floor insulation of at least R-28 for
freezers. (E) For evaporator fan motors of
under one horsepower and less than 460 volts, use
either (a) electronically commutated
motors (brushless direct current motors), or (b)
three phase motors. The portion of the
requirement for electronically commuted
motors takes effect Jan. 1, 2009, unless, prior
to this date, the Secretary determines
that such motors are only available from one
manufacturer. The Secretary may also allow other
types of motors if the Secretary
determines that, on average, these other motors
use no more energy in evaporator fan
applications than electronically commutated
motors. The Secretary shall establish this
maximum energy consumption level no
later than January 1, 2010. (F) For
condenser fan motors of under one horsepower, use
either (a) electronically commutated motors, (b)
permanent split capacitor-type motors,
or (c) three-phase motors.
6How Legislation Affects OEMs
- All new equipment (lt1 HP and lt460V) sold in
California, Washington, Arizona, - Connecticut, Maryland, and New Jersey on
January 1, 2008 require ECM - Testing and qualification of equipment with ECM
motors - Increased cost of new equipment
- Initial increased inventory mix cost
Potential future SKU consolidation - Will accelerate phasing out shaded pole and PSC
motors
7How Legislation Affects Distribution
- Increased cost of new equipment and inventory
- Need to stock replacement ECM motors to support
the new equipment - Opportunities to up sell from shaded pole and
PSC motors to ECM (good, - better, best) in areas where ECM is not
mandated - Increased profit margin
- Potential for Proactive Retrofit opportunities,
driven by energy savings and - risk of component obsolescence
