Diagram Descriptions
Dimension Diagrams
PCM 40 Unit Dimensions: The unit measures approximately 515 mm in height (excluding pipes), 600 mm in width, and 370 mm in depth. Connection ports for hot and cold water circuits are located on the unit.
PCM 42 Unit Dimensions: The PCM 42 unit is taller, with a height of approximately 635 mm (excluding pipes), while maintaining the same width of 600 mm and depth of 370 mm. It also features connection ports for the water circuits.
Capacity Diagrams
PCM 40 Cooling Capacity: This graph illustrates the relationship between cooling output (in kW) and water flow rate (in liters per second, l/s). It shows performance curves for two different temperature differences between the supply and return water: 4°C and 3°C. Higher flow rates and smaller temperature differences generally yield higher cooling outputs within the specified ranges.
PCM 42 Cooling Capacity: Similar to the PCM 40, this graph plots cooling output (kW) against flow rate (l/s) for the PCM 42. It also includes performance lines for 4°C and 3°C temperature differences, indicating a greater cooling capacity range compared to the PCM 40.
