Vari-Level™ Adjustable Level Control

The Hansen Vari-Level Adjustable Level Control provides excellent level control and monitoring flexibility for industrial and large commercial refrigeration systems. It takes the place of multiple single point level switches on new or existing refrigerant vessels.

This popular, user-friendly, and field-proven system consists of a control unit, and a probe to be inserted in a level column. Control unit models are available with up to five individual level set point relays. Level set points and differentials can be easily set up, and then simply changed by moving knobs when necessary. A built-in level simulator enables the operator to easily check proper operation of control valves, pumps, and alarms at the various set points.

For use with ammonia, R22, R134a and other compatible refrigerants.
  • Adjustable levels and differentials
  • Bright digital display of level percentage
  • User friendly
  • Level Set Points always visible
  • Accurately factory calibrated

Advantages

The bright and easily-seen LED digital readout clearly displays liquid level percentage. Each control level set point also has an independent differential control. The low level and operating level differential is easy to understand because it occurs from the set point upward. The “Anti-Splash” dampening feature ignores nominal turbulence in the level column to permit a more accurate liquid level reading and avoid most “false alarms” and shut-downs. A built-in level simulator enables the operator to realistically actuate relays for verification of control level set points and differentials. The overall performance of the control is not affected by normal variations in refrigerant temperature, pressure or contamination.
