2 Ton Water Source Heat Pump | Carrier Vertical, Left Hand Return, Copper Coil, R-454B | 50WCE024FBA3BA-A

The Carrier Aquazone 50WCE024FBA3BA-A is a 2-ton (24,200 BTU/h) vertical water-source heat pump engineered for boiler-tower, geothermal, and hybrid water-loop systems in commercial and multi-family buildings. It runs on Puron Advance (R-454B) — a low-GWP refrigerant (465) that keeps the unit well under EPA limits — and holds a 14.0 EER across an extended entering-water range of 20–110°F, so one loop can serve zones with very different demands. Its left-hand-return cabinet and 3/4 in. water connections let it drop into tight vertical closets on both new construction and retrofit jobs.

In heating mode it delivers 28,300 BTU/h at a 4.7 COP, moving 800 CFM of air on roughly 6.0 GPM of loop water — efficient performance for geothermal and water-loop heat pump systems. Inside, a double-isolated rotary compressor on a floating basepan and ½" closed-cell foam insulation keep operation quiet, while the copper coaxial (tube-in-tube) water heat exchanger and copper-tube/aluminum-fin air coil are tuned for strong latent removal and dependable heat transfer. Standard UPM microprocessor controls manage safeties and diagnostics, with optional Carrier TruVu DDC for seamless i-Vu building-automation integration. Powered by 208–230V / 1-phase / 60Hz and backed by a 1-year parts / 5-year compressor warranty.
