1) Based on differential investment between new, state of the art low charge ammonia refrigeration system and industry standard, HFC based, single stage, air cooled plant with electric defrost divided by reduction in annual energy costs.

2) Average electricity charge $160/MWh (2014)

Scantec Refr igerat ion Technologies designed and installed a two stage, environmentally sustainable and energy efficient ammonia refrigeration system for approximately 43,000m3 refrigerated volume including variable frequency drive reciprocating compressors, variable frequency drive fans, evaporative condenser and computer based automation and monitoring system. Signif icant ly Smal ler Ammonia Charge • 1 kg/kW versus 3-4 kg/kW for liquid overfeed • reduced health and safety risks • reduced regulatory burden in some jurisdictions • faster defrost cycle Energy Eff ic ient:

Integrated Bui ld ing / Refr igerat ion System Design

• optimized evaporator locations for minimisation of infiltration • integrated desiccant drier for minimisation of defrost frequency • building structural and air cooler positioning optimized for cost minimisation • door locations and door design optimized for infiltration minimisation • integrated penthouse designs available for maximisation of pallet spaces • integrated ambient air defrost concepts available for minimisation of energy

consumption • integrated air cooler concepts minimising access to warehouse for maintenance • relative levels within building designed for optimal refrigeration plant performance • lighting types and insulation thicknesses selected for minimum life cycle cost (LCC) • future proofing through use of zero ODP and zero GWP refrigerants • integrated ambient air defrost/emergency ventilation with ambient air defrost type

coolers • long service life through extensive use of non-corrosive materials • more than 100 in-house designed computerized control and monitoring systems in the
