"GRA" series chillers
Models GRA 25B to GRA 450B ‘all stainless steel’ or ‘painted’ construction
The chillers in this series are specifically designed for industrial applications where high reliability in operation and output is required, and in sectors where high cooling power is required.
Models up to GRA 90B can be equipped with an internal, fully insulated, stainless steel, hydro-glycol mixture storage tank with a capacity ranging from 250 litres to 500 litres depending on size. For other models, the storage buffer tank is provided externally and is supplied on request.
The condensing coil of the aluminium finned pack and copper tube type, has independent circuits for each compressor and is able to dissipate the heat produced by the compressor thanks to a high exchange surface area.
The axial electric fans, variable in number and diameter according to the power of the unit, are fitted as standard with a speed regulator, which allows the condensation conditions of the unit to be optimised.
The electrical panel installed on each unit, suitable for external use, has all the control and safety systems on both the power circuit and the auxiliary section.
All GRA chillers are tested at our factory and a certificate is issued upon successful testing to guarantee proper operation.
