“Manhattan Modular” chillers allow easy field assembly of large tonnage systems, without the need for heavy rigging and construction. Quiet operation and highly reliable components and controls provide dependable air-conditioning and more precise load balancing.

Headers are heavy steel tubing with precision grooves. Modules are attached using reliable Victaulic couplings. All slave modules are connected to the Master Module which houses centralized controls and power connections for the bank of chillers.

Modular Chillers solve problems associated with renovation of older buildings where often, they are the only practical choice.
