Energy efficiency is a key focus in all our product development. Marstair have a range of refrigeration condensing units (MRC+) on the Carbon Trust Energy Technology List which aims to only include equipment which are in the top 25% most efficient available on the market. These refrigeration condensing units are also suitable for the newly available low global warming potential refrigerants R448A and R449A and have heat recovery alternatives available (GreenHeat). Marstair also have a new range of air conditioning evaporators suitable for use with CO2 refrigerant. These units have been specifically designed to improve the energy efficiency of modern retail outlets by allowing the coordination of the air conditioning and refrigeration systems using CO2 refrigerant giving extensive heat recovery benefits.
