Tandem

Chillers, Pump Packages

Tandem Chillers manufactures modular chillers and pump packages for commercial HVAC applications. Its “Service-in-Place” designs allow individual components to be serviced or replaced while the remaining equipment continues operating. Water-cooled and air-cooled configurations provide options for different building systems and installation conditions. Compact modules help address limited space and difficult access, making them useful for equipment replacement projects. Systems can also be planned for future capacity expansion, with pump packages configured around the required water or glycol circulation.

Products That Fit Your Needs

Tandem Chillers’ modular chillers and pump packages provide flexible cooling solutions, with service-in-place designs that help maintain operation during equipment maintenance.

Water-Cooled Chillers

Water-cooled modular chillers provide cooling for buildings with a condenser water system. Compact designs help accommodate limited space, while service-in-place configurations allow maintenance on individual components as other modules continue operating.

Air-Cooled Chillers

Air-cooled modular chillers provide cooling without a cooling tower. Compact designs suit outdoor installations, with dual-circuit configurations that allow one compressor to remain in operation while the other is serviced.

Pump Packages

Pre-piped and wired pump packages support water or glycol circulation. Configurations include single or multiple pumps, with operating and standby arrangements available to match the system’s flow requirements and installation space.
