The Zero range features a variety of horizontal and vertical units in different sizes, to suit different locations. They are finished in stainless steel, so are easy to clean. The Zero can be operated in two ways, either by pre-set parameters, which can be chosen to suit the type of food - nine basic programmes are supplied as standard - or the operator can design individual programmes to suit specific requirements. The programmes can be input by a control panel with LCD display.
There is an automatic hot-gas defrost system that removes ice quickly to ensure continuous operation; manual defrost is also an option. All ISA's products use 100% HCFC-free polyurethane insulation and eco-friendly refrigerant gases.
