FLEX Modular Heat Pump Chillers
for Commercial Buildings

EXINDA FLEX four-pipe modular heat pump chillers deliver simultaneous heating and cooling for offices, hotels, schools, healthcare facilities and multifamily buildings. Separate hot-water and chilled-water circuits let perimeter rooms receive heating while interior spaces are cooled, without a building-wide seasonal changeover. Heat recovered from cooling is reused on the heating side, making productive use of energy that would otherwise be rejected outdoors. Combine modules to match building demand, plan phased expansion and support the transition from conventional boiler-and-chiller plants to electric heating and cooling.

A 12 Ton option for commercial hydronic projects using one circuit for seasonal heating and cooling. Supply fan coils or air handlers with chilled water and compatible heating terminals with hot water.

Meet larger building loads with the 24 Ton option. Inverter control adjusts output as demand changes, supporting commercial heating and chilled-water cooling through a shared two-pipe loop.

A higher-capacity module for larger hydronic systems and phased plant upgrades. Combine units around the project load, with 40 Ton heating or 35 Ton cooling per unit and seasonal mode switching.

Bring heat recovery into offices, education, healthcare and multi-residential developments. The FLEX four-pipe system supplies hot and chilled water together, reusing heat from cooling to serve the heating circuit. Modular layouts support new buildings and phased plant renovations.

Year-round comfort for smaller offices and hospitality buildings. The 45 kW R290 unit supplies heating in winter and chilled-water cooling in summer through a two-pipe hydronic system.

Serve more rooms and larger shared areas with 90 kW heating capacity. This R290 unit offers the same seasonal heating and cooling functions for projects with greater demand.
