ENERGY STAR for Rebuilt Refrigerated Vending Machines

Beverage companies rebuild vending machines to extend their life.

A vending machine can be rebuilt two or three times and stay in service over 15 years.

US EPA has a draft criteria for an ENERGY STAR rating for refurbished vending machines.

Requirements Refurbishment centre and original equipment manufacturer

must be ENERGY STAR partners. Rebuilt machine must meet the energy consumption and low-

power mode requirements of ENERGY STAR.

Opportunity – Condensing and near-Condensing Boilers

CSA 4.9 (ANSI Z21.13) safety standard requires that boiler greater than 300,000 Btu/hr have a minimum combustion efficiency of 80%.

Proposed High Efficiency Criteria

Tier 1 : 85 - 88% (near condensing) Tier 2 : 89% and above (condensing)

Technologies/Applications to meet these levels: • Corrosion resistant heat exchanger – stainless steel

• PVC Venting of combustion products – condensing

• Stainless steel chimney liners – near condensing

• Condensing boilers – require return water temperatures (50ºC max)

• Medium efficiency boilers – require higher return water temperature Condensing boilers are not recommended for all applications:

• Condensing boiler – applications using hot water at low temperature.• Mid-efficiency boiler – applications needing hot water at high

temperature
