Air cooled packaged water chillers Models RMA/E-PC from 0,5 to 181 kW with reciprocating or hermetic scroll compressors

Product catalog summary

Overview
The document outlines the RMA/E-PC models of air-cooled packaged water chillers, which have capacities ranging from 0.5 to 181 kW. These chillers use either reciprocating or hermetic scroll compressors and are designed for outdoor installation. They primarily use R407C refrigerant, with options for R22 and various power supplies available upon request.

Specifications

Compressors: The chillers use hermetic piston and scroll compressors, known for their energy efficiency, reduced noise, and minimized vibrations. They include safety features like overpressure protection and non-return valves.
Evaporator: These are finned coil types with copper tubes and aluminum fins, located inside the water storage tank to minimize pressure drops and prevent freezing.
Condenser Coils: Constructed with copper tubes and aluminum fins, these coils are designed for high efficiency and can be installed in confined spaces.
Axial Fans: These fans have die-cast aluminum impellers with ON/OFF or continuous speed control and are protected against overloads.
Cooling Circuit: Features include high and low-pressure switches, a drier filter, and a thermostatic expansion valve.
Structure and Casing: The units have separate compartments for compressors, tanks, and electrical panels, with a fully enclosed design for larger models.
Electrical Panel: Complies with EN 60204-1 standards and includes automatic switches and microprocessor control cards.
Hydronic Group: Comes with a built-in storage tank and centrifugal pumps, with a manual filling kit available for all models.

Control and Management
The chillers are controlled by microprocessor units, with models using either the chiller2 or pCOXS units, which feature various display types for monitoring.

Performance Data
The document provides a table of cooling capacities at different ambient temperatures, detailing the maximum ambient temperature and cooling capacity for each model. The data is based on specific inlet and outlet water temperatures, with further specifications available upon consultation.
