Rheem rxjj-dd20cp Commercial Electric Heat Kit 20kw 208-230V 3-phase 60hz 7.5-12.5 Ton

Product Description

The Rheem RXJJ-DD20CP is a commercial electric heat kit rated at 20 kilowatts. It is designed to add electric resistance heating capacity to Rheem Renaissance Line package air conditioner units ranging from 7.5 to 12.5 tons. HVAC technicians and commercial mechanical contractors use this heat kit during new installations or system upgrades where supplemental or primary electric heat is required in a packaged rooftop or ground-level unit. The kit operates on 208 or 230 volts, three-phase, 60 Hz power, making it well-suited for commercial buildings with three-phase electrical service. Three-phase electric heat kits like the RXJJ-DD20CP distribute load evenly across all three phases, which reduces electrical imbalance and supports stable performance in larger commercial HVAC systems. At 20 kilowatts, this kit delivers substantial heating output for mid-size commercial spaces such as retail stores, office suites, warehouses, and light industrial facilities. The unit ships at approximately 34 pounds and has an installed item weight of 31.5 pounds, making it manageable for rooftop installation with standard commercial HVAC service equipment. Proper sizing is critical with commercial heat kits. The RXJJ-DD20CP is engineered specifically for compatibility with Rheem Renaissance package air conditioner units in the 7.5 to 12.5 ton range. Using this kit outside of that application range or with non-compatible equipment is not recommended. HVAC technicians should always verify voltage, phase, and tonnage compatibility before ordering. This heat kit integrates directly into the Rheem Renaissance packaged system, working alongside the existing refrigerant circuit and controls. The result is an all-in-one packaged unit capable of delivering both cooling and electric heat from a single rooftop or ground-mounted cabinet. This simplifies installation, reduces wiring complexity, and keeps the mechanical footprint tight. The RXJJ-DD20CP is an OEM-sourced Rheem component, which means it is built to match the electrical and mechanical specifications of the Renaissance platform without requiring field modifications.
