Grasso Products B.V. and Grasso GmbH Refrigeration Technology, both members of the multinational GEA AG, are one of the world’s leading manufacturers of innovative recriprocating and screw compressors, packages, chillers and components for industrial refrigeration plants and freezing systems. More than 90% of which ae exported all over the world.

• Recriprocating compressors and packages, single and two stage, open and semi and two-stage, open and semi-hermatic, 53 types, with sewpt volmes ranging from 130 to 2390 m3/h (77 to 1410 CFM).
• Single and two-stage screw compressor packages, 18 screw compressor models, with swept volumes ranging from 230 to 5800 m3/h (164 to 4122 CFM).
• Ammonia liquid-chillers for air conditioning or process cooling, recriprocating compressor types ranging from 75 to 700 kW (21 to 200 Tons) and screw compressor types, ranging from 200 to 6000 kW (57 to 1710 Tons).
• Electronic control units.
• Refrigeration valves and components.
• Self-limiting Automatic Purgers of non-Condensable gases.
• Pressure vessels.
• Maintenance of refrigeration systems.

RHOSS bases its design philosophy on one fundamental concept: testing the behaviour of its produced machines in all the environmental conditions in which they can be used. A responsible manufacturer must in fact provide designers with correct data regarding its products under all operating conditions, because each air conditioning unit must deliver a specific energy performance that can vary based on geography, building features and use requirements.

With its testing rooms, Rhoss’s R&D Lab provides its customers with a series of guarantees that are necessary for a conscious design:

• Guarantee of performance under the design conditions, which are usually different than Eurovent nominal conditions.
• Guarantee of efficiency at full load (EER, COP) or at partial loads (ESEER).
• Guarantee of continuous operation, especially under the most critical operating conditions.
• Simply think of severe climates where the ambient air can exceed 50 °C or go down below–15 °C.
• The possibility for the design or end customer to carry out customised tests.

Therefore, Rhoss is able to offer products designed for large and small capacity systems, guaranteeing that all the components used are integrated together, with a perfect control logic. This result can only be obtained in laboratories such as Rhoss’s R&D Lab, that is, in a complex, technically advanced structure that most other manufacturers today do not have.
