Purchasing Energy-Efficient Commercial Fryers

The Federal Energy Management Program (FEMP) provides acquisition guidance for commercial fryers, a product category covered by ENERGY STAR efficiency requirements. Federal laws and requirements mandate that agencies purchase ENERGY STAR-qualified products or FEMP-designated products in all product categories covered by these programs and in any acquisition actions that are not specifically exempted by law.

FEMP's acquisition guidance and associated ENERGY STAR efficiency requirements apply 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 General Service Administration (GSA) buildings, kitchens in penitentiaries, and commissaries on military installations.

This acquisition guidance was updated in December 2015.

Find Product Efficiency Requirements

The U.S. Environmental Protection Agency (EPA) provides commercial fryer efficiency levels and product specification information on its ENERGY STAR website. Manufacturers meeting these requirements are allowed to display the ENERGY STAR label on complying models. Get a list of ENERGY STAR-qualified fryers.

Make a Cost-Effective Purchase: Save More than $250 by Buying ENERGY STAR

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

Electric Deep-Fat Fryers

For an electric deep-fat fryer, the required ENERGY STAR-qualified model saves money if priced no more than $265 above the less efficient model. The best available model saves up to $900. Table 1 compares three types of product purchases and calculates the lifetime cost savings of purchasing efficient models. Federal purchasers can assume products that meet ENERGY STAR efficiency requirements are life cycle cost-effective.

Determine When ENERGY STAR Products Are Cost-Effective

An efficient product is cost-effective when the lifetime energy savings (from avoided energy costs over the life of the product, discounted to present value) exceed the additional up-front cost (if any) compared to a less efficient option. ENERGY STAR considers up-front costs and lifetime energy savings when setting required efficiency levels. Federal purchasers can assume ENERGY STAR-qualified products and products that meet FEMP-designated efficiency requirements are life cycle cost-effective. In high-use applications or when energy rates are above the federal average, purchasers may save more if they specify products that exceed federal efficiency requirements, as shown in the Best Available column above.

Users who wish to determine a product’s cost-effectiveness for their application may do so using the Savings Calculator for ENERGY STAR Certified Commercial Kitchen Equipment.

Claim an Exception to Federal Purchasing Requirements

Products meeting ENERGY STAR or FEMP-designated efficiency requirements may not be life cycle cost-effective in certain low-use applications or in locations with very low rates for electricity or natural gas. However, for most applications, purchasers will find that energy-efficient products have the lowest life cycle cost.

Agencies may claim an exception to federal purchasing requirements through a written finding that no FEMP-designated or ENERGY STAR-qualified product is available to meet functional requirements, or that no such product is life cycle cost-effective for the specific application. Learn more about federal product purchasing requirements.

Incorporate Federal Acquisition Regulation Language in Contracts

These mandatory requirements apply to all forms of procurement, including construction guide and project specifications; renovation, repair, energy service, and operation and maintenance (O&M) contracts; lease agreements; acquisitions made using purchase cards; and solicitations for offers. Federal Acquisition Regulation (FAR) Part 23.206 requires agencies to insert the clause at FAR section 52.223-15 into contracts and solicitations that deliver, acquire, furnish, or specify energy-consuming products for use in federal government facilities. To comply with FAR requirements, FEMP recommends that agencies incorporate efficiency requirements into technical specifications, the evaluation criteria of solicitations, and the evaluations of solicitation responses.

Find Federal Supply Sources

The federal supply sources for energy-efficient products are the General Services Administration (GSA) and the Defense Logistics Agency (DLA). GSA sells products through its Multiple Awards Schedules program and online shopping network, GSA Advantage!. DLA offers products through the Defense Supply Center Philadelphia and online through 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.

The United Nations Standard Products and Services Code (UNSPSC) is a worldwide classification system for e-commerce. It contains more than 50,000 commodities, including many used in the federal sector, each with a unique eight-digit, four-level identification code. Manufacturers and vendors are beginning to adopt the UNSPSC classification convention and electronic procurement systems are beginning to include UNSPSC tracking in their software packages. UNSPSCs can help the federal acquisition community identify product categories covered by sustainable acquisition requirements, track purchases of products within those categories, and report on progress toward meeting sustainable acquisition goals. FEMP has developed a table of ENERGY STAR and FEMP-designated covered product categories and related UNSPSC numbers.

Commercial Fryer Schedules and Product Codes

GSA offers energy-efficient commercial fryers through Schedule 73 (Food Service).

DLA's ENAC for commercial fryers is "HE."

The UNSPSC for commercial fryers is 48101509.

Buyer Tips: Make Informed Product Purchases

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.

Many states and electric utilities offer rebates or other incentives for the purchase of ENERGY STAR-qualified products. Use the ENERGY STAR Rebate Finder to see if your local utility offers these incentives. FEMP’s Energy Incentive Program helps federal agencies take advantage of these incentives by providing information about the funding-program opportunities available in each state.

User Tips: Use Products More Efficiently

Studies have shown that fryers are used 25% of the time they are on. Because 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.
