The Vari-Level™ Adjustable Level Control by Hansen Technologies offers precise and adaptable liquid level management for industrial and large commercial refrigeration systems. This system comprises a control unit and a probe inserted into a level column, effectively replacing multiple single-point level switches in refrigerant vessels. Models are available with up to five individual level set point relays, allowing for easy adjustment of level set points and differentials via user-friendly knobs. A built-in level simulator enables operators to verify the proper operation of control valves, pumps, and alarms at various set points. The bright LED digital readout clearly displays liquid level percentages, and the system is designed to withstand normal variations in refrigerant temperature, pressure, or contamination. Suitable for use with ammonia, R22, R134a, and other compatible refrigerants, the Vari-Level™ system enhances control and monitoring flexibility in refrigeration applications
