Multifamily Buildings

  • Prevent Overheating

    Did you know that more than 85% of multi-family buildings have inefficient heating systems? Major complaints beside very little heat in a city apartment, is an overheated apartment. New Yorkers’ solution to overheated apartments for years has been to open up their windows, to release some of the heat trapped in their apartments. Many of these buildings are overheated simply because they have a hard time ensuring that every apartment is heated. So some apartments in the same building might be overheating while other apartments might just have enough heat to comply with local codes and laws.

    There are solutions for these old apartment buildings that have problems with overheating by their water or steam radiators. The EPA, EEFA, and other environmental agencies recommend installation of thermostatic radiator valves or TRVs on every radiator in the building. Most TRVs do not require electricity, are easy to install by almost any handy person, and are very economical. TRVs have a built-in sensor that opens and closes the radiator according to the temperature in the room, providing an individualized comfort control to any room.

    Solutions

    RA2000 Thermostatic Radiator Valves (TRVs)

    Danfoss offers effective and simple solutions in a wide variety of inlet supply patterns, connections & sizes to fit your installation needs. The operator and valve are selected separately to tailor to each individual application.

    Whether you're looking for a tamper-proof option, installing on a radiator, or convector, Danfoss can help assist with selecting the correct option for your building.

    Reduce high energy bills, control tenant comfort levels & save money - without compromising quality with Danfoss TRVs.

  • Benefits

    Simple to Control

    Easily accomplish a comfortable room temperature by turning the dial clockwise or counter-clockwise.

    Simple to Install

    Install quickly and easily without the need for tools with RA2000's snap on mechanism that locks the operator onto the valve.

    Improved Comfort

    As room temperatures change throughout the day, the internal thermostat senses those changes, and opens or closes to maintain your perfect temperature.  This provides better control of individual room temperatures leading to enhanced comfort.

    Energy Savings

    Avoid overheating and open windows by gaining better control of your system, increasing efficiency, and energy savings.

    Only TRV with a Gas Fill

    One of the secrets of the TRVs extended lifetime is the gas charged, precision-manufactured sensors. Danfoss specifically chose to engineer our sensors with a gas fill, due to the accelerated response time, compared to other design methods. RA2000 sensors react the quickest - keeping you the most comfortable!

    Applications

    One Pipe Steam Systems

    Solutions specifically designed for use with one-pipe low pressure steam systems. Typical installations include:

    • Free Standing Radiators
    • Enclosed Radiators
    • Convectors  

    Two Pipe Hot Water Systems

    Solutions specifically designed to regulate the flow of hot water through:

    • Free Standing Radiators
    •  Convectors
    • Baseboards 
    Retrofit Systems 

    Convert your old, outdated, confusing & hard to set SWRF B Valves (example) into a thermostatically controlled radiator valve with inserts from Danfoss. Upgrading these ancient valves can prove substantial energy savings.

     

    Rebates & Incentives

    Did you know most gas utilities offer either incentives and/or rebates to install TRVs on one-pipe steam systems if you are on firm/uninterruptible gas? For additional details on current programs that can help you save on TRV installations, see below.
  • About Us

    The Danfoss Mission on Sustainability

    Danfoss, a pioneer in the comfort control industry for over 80 years, was born on September 1, 1933, when Mads Clausen founded Danfoss in his parents’ farmhouse in Nordborg, Denmark.

    Since then, the business has grown from a solo enterprise into one of the world’s leading suppliers of energy-efficient, reliable, & innovative solutions, employing a staff of more than 24,000 - with sales in more than 100 countries.

    The first radiator thermostat for mass production was developed by Danfoss in 1948. Since then, Danfoss has launched easy-to-install, secure snap-on features on control heads, gas filled operators for the fastest reaction times, and space age plastics to withstand the extreme temperatures of older steam systems.
