Air Cooled Packaged Module - Multistack

AIR COOLED PACKAGED MODULE
Introduction
Multistack ASP
The chiller will consist of modules (one master, front or back), with an optional
free cooling module (no compressors), an optional water pump module, optional
water holding tank module (not pictured) and optional glycol feeder module
(not pictured).
Master Module
The master module for each chiller is designated at the factory and is
equipped with the master microprocessor display.
Front Module
Front Modules contain the (4”, 6” or 8”) water header distribution pipes and
has a slave control board. This module will bolt together with the rear module.
Note: ASP-020X, -030X and -060X uses 6” header.
Rear Module
This module will be attached to the front module by vertical frame bolts and
the evaporator is connected by cross over pipes to the front modules water
header pipes. It also has its own slave board. (There is no rear module on
the ASP-060X)
Pump Package Module
This module contains a centrifugal dual-arm pump and water distribution
headers. This module is for installations where no pump is provided for the
chilled water system or when additional pumping capacity is required.
Note: Several configurations of pump modules are available. Typical
pump is shown.

Free Cooling Modules
This module has fin and tube coils for free cooling operation and no mechanical
refrigeration (no compressors). The module contains a three-way diverting
valve for either enabling free cooling or bypass for mechanical cooling.
Note: Free cool modules can come as fronts (with headers) or rears
(without headers).
