FLEXIBILITY IN DESIGN
A Multistack chiller is a bank of individual chiller modules connected in parallel to operate as a single machine. Each SRW 075 & 085 module contains two completely independent refrigeration circuits. Cooling capacity is matched to load demand by varying the number of refrigeration circuits in operation.

COMPACT AND SPACE-SAVING
With each module approximately 550mm wide, you can install these quiet, compact units in small and confined spaces. In new buildings, you can reduce the size of plant rooms and save on structural costs.

LOWER INSTALLATION COST
The compact size of each chiller module means easy access via standard lifts and standard doorways. You don’t need expensive cranes or special rigging. Connecting the modules is simple – you only have four pipes. An active link connects electrical power. Clip in the control connections and you’re in business. Fast.

SAFE AND RELIABLE
Every module works as an independent refrigeration circuit, with adjacent modules operating independently. In the event of a malfunction in the system, the computer selects the next available standby module to provide back up. One failed module will not disrupt the rest of the system, giving you total piece of mind.

STRUCTURE
MULTISTACK Air Cooled Chillers are designed and constructed under the modular technology patent. A chiller bank consists of multiple individual chiller modules connected in parallel to operate as a single machine, with cooling or heating capacity to match the load demand by varying the number of operating modules. The chiller modules start from a small half module, and expandable to fifteen full modules for SRA131 and SRA150 and ten for SRA290 and SRA340, giving you full flexibility to increase the capacity as your needs increase.

ENVIRONMENTALLY FRIENDLY
Multistack Chillers are friendly to the environment, and currently running on the non-toxic R22 refrigerant (approved under the Montral Protocol, and for sale until 2030) as standard, along with the R407c and R134a as optional. It is also pleasing to the ears, running quietly even at 100% capacity.
