Welcome to our Booth! We'd love to hear from you!

State of the Art Safety Controls!

Hydrolevel Company was founded in 1965 by Michael DeLeonardis, an engineer specializing in steam pressure vessels. Through his vast experience with steam boilers, Michael became well aware of the shortcomings of float-type level controls. By utilizing water’s ability to conduct electricity, he designed a non-moving electrode that accurately detected water within a boiler. The Safgard trademark was launched and production of the first probe-type low water cut-off was underway.

Since that time, Hydrolevel has incorporated its proven technology into a line of temperature limit/low water cut-off combinations, low water cut-offs for steam and hot water boilers, state of the art water feeders, multi-purpose tank level controls, condensate pump controllers, and more.

Hydrolevel is located in North Haven, Connecticut, where we manufacture all of our quality products. Hydrolevel proudly supplies most major boiler manufacturers and serves the needs of heating contractors through plumbing and heating wholesalers nationwide.

  • AcuTemp Temp Control
    Hydrolevel's Adjustable Temperature Control!...

  • Temperature Control at the Turn of a Dial!

    The AcuTemp utilizes a microcontroller-based design to control water temperature. An advanced software algorithm closely monitors the rate of tank temperature changes and controls the heating source to minimize fluctuations in tank temperature while optimizing fuel efficiency. 


    Features and Specs

    • Continually monitors the rate of change to optimize water temperature and minimize under and overshooting
    •  LED Display indicates current temperature set point
    • Push-to-Set Dial provides easy setup while guarding against unintended changes
    • Adjustable temperature settings for both residential and commercial temperature operating ranges
    • Fahrenheit or Celsius settings
    • Suitable as replacement control on virtually any indirect water heater (requires 24V power supply)

    Input: 24 VAC, 60 Hz

    Power: 2.4 VA

  • Fuel Smart Hydrostat (Universal Boiler Control)
    Our Universal 3-Function Boiler Control...

  • The Last Boiler Control You'll Ever Need!

    The Fuel Smart HydroStat's reliable 3-function desgin, (Temp limit, Boiler Reset, Low Water Cut-Off) has made it the standard equipment on many premier cold start and tankless boiler lines. In ADDITION to it's 3-function desgin, the Fuel Smart Hydorstat acts as a UNVIERSAL replacement, being able to fit on virtually all popular boiler models on the market. 


    Features

    3-Function Desgin

    • Temperature Limit: Designed for cold start and tankless coil boilers
    • Low Water Cut-Off: Provides protection against potentially dangerous low water conditions when installed with the Hydrolevel Electro-Well™
    • Thermal Targeting On-board microprocessor saves fuel by adjusting boiler temperature based on heating demand 

    Other Features

    • Outdoor Reset Ready: Provides outdoor reset and warm weather shutdown with addition of Outdoor Sensor Kit
    • Easy Dial-Type Set-up: Simply dial in the Temperature Limit and Economy settings.
    • Dynamic Display: Continually displays boiler temperature. Intermittently displays outside temperature when in outdoor reset mode. Instantly changes to display control settings when any dial is adjusted.
    • Test/Settings Button: Press and hold to test the Low Water Cut-Off operation (operational when control is installed on an Electro-Well™),  Press momentarily to scroll through control settings (High Limit, Low Limit, Economy Setting, and the current Boiler Reset Target Temperature).
    •  LED Status Lights: Continually indicates which functions are active and if the control is holding the burner off for any reason.
    •  Smart DHW Priority: Closely monitors boiler temperature when calls for domestic hot water coincide with space heating calls. The control will prioritize the domestic hot water call only when needed.
    • Call for Heat Indicator: Illuminates on any call for heat.
