New 2020 multiplex system 60kw to 430kw of cooling 

The max & min capacities are subject to interpretation, such as suction temp, superheat, and condensing temp.

However, we have put together information regarding the capabilities of the semi-hermetic multiplex solution we are able to provide. 

Currently, we designed the new rack range to accommodate 3, 4, and 5 Copeland Stream Semi-Hermetic compressors.

The conditions for the cooling capacities and multiplex running current are based at -10 ˚C suction temperature and 45 ˚C condensing temperature.

 Direct Capacity:         

  Smallest 3 Comp (33 % - 100 %) - 19 to 60 kW (16.4 to 70 A)  to  Largest 5 Comp (20 % - 100 %) -  74 to 370 kW  (62 to 330 A) 

Digital Modulation:

Smallest 3 Comp (16.7 % - 100 %) - 15 to 90 kW (17.5 to 95 A)  to Largest 5 Comp (10 % - 100 %) - 35 to 350 kW (28 to 310 A)

Unloader Modulation:

Smallest 3 Comp (16.7 % - 100 %) - 15 to 90 kW (17.5 to 95 A) to Largest 5 Comp (7 % - 100 %) - 26 to 370 kW (42 to 330 A)

Freq. Modulation @ 60 Hz:

Smallest 3 Comp (19 % - 100 %) - 18 to 90 kW (14 to 95 A)  to Largest 5 Comp (12 % - 100 %) -  45 to 430 kW (34 to 380 A)   Thus, in summation the full running cooling capacity is from 60 to 430 kW, however steps and modulation potential creates the opportunity to match
