Covered Product Category: Commercial Fryers

ENERGY STAR Qualified Products

The Federal Energy Management Program (FEMP) provides acquisition guidance for commercial fryers, which is a product category covered by the ENERGY STAR program. Federal laws and executive orders mandate that agencies meet these efficiency requirements in all procurement and acquisition actions that are not specifically exempted by law.

Meeting Energy Efficiency Requirements for Commercial Fryers

ENERGY STAR sets efficiency requirements for commercial fryers in its product specification. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models. For the most up-to-date requirements and list of qualified products, visit the ENERGY STAR website.

Defining the Product Category

This product overview and associated ENERGY STAR product specification applies to commercial standard and large vat open deep-fat fryers. Pressure, specialty, and fryers less than 12 inches wide or greater than 24 inches wide are excluded. In the Federal sector, these products are typically used in commercial food service operations like cafeterias in GSA buildings, kitchens in penitentiaries, and commissaries on military bases.

The Federal supply sources for commercial fryers are the General Services Administration (GSA) and Defense Logistics Agency (DLA). GSA sells fryers through its Multiple Awards Schedules program and online shopping network, GSA Advantage! DLA offers products through the Defense Supply Center Philadelphia and online through the DOD EMALL. Products sold through DLA are codified with a 13-digit National Stock Number (NSN) and, in some cases, a two-letter Environmental Attribute Code (ENAC). The ENAC identifies items that have positive environmental characteristics and meet standards set by an approved third party, such as FEMP and ENERGY STAR. When buying commercial fryers through DLA sources, look for models with the ENAC "HE" attached to the end of the NSN.

The United Nations Standard Products and Services Code (UNSPSC) is a worldwide classification system for use in eCommerce. It contains over 50,000 commodities, including many used in the Federal sector, each having a unique eight-digit identification code. Using the UNSPSCs will assist buyers with identifying covered product categories and improving record keeping. The UNSPSC for commercial fryers is 48101509.

Reducing Energy Costs: Save More Than $300 When You Buy Energy Star-Qualified Products

FEMP compared lifetime energy cost savings and the up-front purchase price of several commercial electric and gas fryer models.

Electric Deep-Fat Fryers

FEMP calculated1 that the required ENERGY STAR-qualified electric deep-fat fryer is cost-effective if priced no more than $335 above the less efficient alternative. The most efficient level saves the average user more money: $915. The complete cost-effectiveness example and associated assumptions are provided in Table 1.

Determining Cost-Effectiveness

An efficient product is cost-effective when the discounted savings (from avoided energy costs over the life of the product) exceed the additional up-front cost (if any) compared to a less efficient option. ENERGY STAR and FEMP consider up-front costs and lifetime energy savings when setting required efficiency levels so that Federal purchasers can assume that ENERGY STAR-qualified and products meeting FEMP-designated efficiency requirements are life cycle cost-effective. However, users wishing to determine cost-effectiveness for their application may do so using the Commercial Kitchen Equipment Savings Calculator on the ENERGY STAR website.

For most applications, purchasers will find that energy-efficient products have the lowest life cycle cost. In high-use applications or when energy rates are above the Federal average, purchasers may save more if they specify products that exceed the Federal efficiency requirements, as shown in the Best Available columns above.

Exceptions

Products meeting FEMP-designated efficiency requirements or ENERGY STAR performance specifications may not be life cycle cost-effective in certain low-use applications, or in locations with very low rates for natural gas or electricity. In these cases, the agency may pursue an exception to the Federal procurement requirement.

Complying with Contracting Requirements

These requirements apply to all forms of procurement, including guide and project specifications; construction, renovation, repair, energy service, and operation and maintenance (O&M) contracts; lease agreements; and solicitations for offers. Energy performance requirements should be included in all evaluations of solicitation responses.

Federal Acquisition Regulation (FAR) Part 23.206 requires Federal agencies to insert the clause at FAR section 52.223-15 in solicitations and contracts that deliver, acquire, furnish, or specify energy-consuming products. FEMP recommends that agencies incorporate efficiency requirements into both the technical specification and evaluation sections of solicitations. Agencies can claim an exception to these requirements through a written finding that no ENERGY STAR-qualified or FEMP-designated product is available to meet the functional requirements, or that no such product is life cycle cost effective for a specific application. Additional information on Federal requirements is available.

Buyer Tips: Choosing Efficient Products

When buying commercial fryers, specify or select fryers that are appropriately sized for their intended use. Oversized products will increase the initial cost and lead to excessive expenses due to additional energy losses.

Features to look for when buying energy-efficient gas fryers include recirculating tubes, low oil volume, induced draft and serpentine heat exchangers, and powered and infrared burners. When buying electric fryers, look for improved heating elements and controls. Insulation can increase efficiency in both gas and electric models. Energy-efficient fryers have higher production rates and shorter recovery times than base models, and in some cases can eliminate the need for a backup fryer.

User Tips: Using Products More Efficiently

Studies have shown that fryers are used 25% of the time they are on. Since most fryers take less than 15 minutes to preheat, implementing a start-up/shut-down schedule could save substantial amounts of energy. Turning off backup fryers during nonpeak periods can save up to $150 per year. Do not load fryers beyond their recommended capacity because this will increase cooking time and reduce product quality.
