MC Series
Commerical & Industrial Water or Air Cooled Modular Chillers
The Engineered Air MC Series is a line of modular water-cooled and remote air-cooled chillers (packaged air cooled are available) that range in size from 20 to 80 nominal tons. They can operate as a stand alone unit or in combination of up to 12 chiller modules to increase cooling capacity as needed. Single stand-alone models are available in the 3 to 80 ton range.
The principle of modular chiller design is that a smaller individual chiller (a module) can be connected with other modules to create a larger cooling system, either initially or over time. Sections of 6″ (152mm) diameter pipe connected with Victaulic couplings are used to form a common header. This allows the common header to be pre-shipped to the job site and piped into the building piping system before the rest of the equipment arrives.

Benefits
Expandability
Allows the system to grow with the cooling load. Modules can be added at a future date without doing any piping work.
Better Capacity Control
Each individual circuit is operating at its optimum efficiency point, providing a high operating efficiency even though the overall assembly is operating at partial load.
Installation
Units are connected to the header using isolation valves and flex joints, meaning they can be mounted directly onto a concrete slab. Header sections are identical to one another. They can be pre-shipped ahead of the chillers, allowing the building piping system to be pre-built.
Flexible Installation Arrangements
The external common header means that modules can be located in different parts of the room or even in separate rooms. As long as the piping is connected so that the master controller measures the system fluid temperature, the system will work effectively.
Service While Under Full Operation
Designed to allow service to all the liquid line components on any of the chillers while the system is under operation.
Redundancy
Add one more module to the system for an “N + 1” capacity so that the overall cooling system capacity is not affected when a module is taken out for regular service or needs repair. Each unit has two independent circuits. If one is lost, only that circuit is affected while all others remain operational. Each module has a fully functioning dedicated logic controller. If communication is lost with the master controller, the individual controllers will automatically take over control of each module. By presetting and staging the set points on all the local controllers, they will then control the system.
Front Serviceability
Set up so that it is front serviceable making it easy to access components requiring routine maintenance.
