Key Benefits Precise Refrigerant Control: Maintains steady superheat to ensure the evaporator remains fully active without risking liquid floodback to the compressor

Ammonia Compatible: Constructed with stainless steel internals specifically for use in ammonia-based refrigeration systems

The 904681 typically uses a multi-speed motor (often 3-speed or 4-speed depending on the specific production run) to accommodate different BTU ratings and cooling tonnages

Direct OEM Compatibility: Precise match for ClimateMaster 24B0004N04 and Grundfos UP26-116U specs

Hartland Controls TRAN-50VA Transformer 318518-761 and occupancyThe Hartland Controls TRAN 50VA Transformer is a heavy duty, multi tap power solution designed for professional HVACR applications. Engineered as a 50VA control transformer, this unit steps down primary line voltages of 120V, 208V, or 240V AC to a stable 24V AC secondary output. This multi tap HVAC transformer features 18AWG stranded leads and is inherently limited, meaning it does not require secondary fusing for protection. Built with a Class B
