Energy Efficient Valves Providing Optimal Performance

EPIV_application_960X530

With Belimo’s pressure independent control valve technology only a single valve is required to maintain proper flow through each circuit. Each valve arrives from the factory pre-set for each circuit and can be changed in the field, so there is no additional balancing required. The system performs perfectly from start-up. Pressure independent valves are used to regulate flow through air handlers, heating and cooling coils, fan coil units, unit ventilators and VAV re-heat coils.

Consulting Engineers

ICON_consulting-engineer

Your analytical skillset makes you an invaluable asset to your organisation. Though your job is to design systems and operating sequences that meet energy codes to make facilities run more efficiently, you constantly find yourself collecting information and analysing data when it could be spent looking for new and innovative ways to save energy and improve building performance. Belimo Pressure Independent Valves can:

  • Dynamically balance the load under all operating conditions
  • Provide True Flow reading for fast TAB verification and BMS data logging via BACnet
  • Eliminate costly problems associated with low Delta T syndrome
  • Precisely match designed requirements for KW and Delta T at the load with patented Power Control
  • Ensure that projects bids remain under budget and installations occur on time

Contractors & Distributors

ICON_contractors-distributors

You're tasked with running a lean and mean operation—however, finding new and effective ways to provide unique solutions to client problems are key to achieving the ultimate goal of increasing profits and growing your business. You feel like far too much of your time is spent diagnosing technical issues and troubleshooting problems for others when it should be spent getting the job done and moving on to the next one. Pressure Independent Valves can:

  • Solve client’s low Delta T syndrome problems to reduce pump cost, and release plant capacity
  • Maintains pressure independent operation from 35 to 350 kPa to ensure optimal system performance
  • Enhanced communication with BACnet, MS/TP, and Modbus RTU to provide superior application data access for easy troubleshooting, commissioning, and programming
  • Offer easy installation in tight spaces
  • Continuous balancing eliminating overflow of coil reducing pumping costs

Building Owners

ICON_bldgowner

Building expansion and tenant improvements are a constant challenge to your facility department and the value of your property. You are having difficulty keeping clients comfortable, identifying ways to optimise your HVAC system, and preserving capital budgets. Pressure Independent Valves:

  • Utilise system data to improve coil and system performance achieving increased energy savings
  • Showcase your building by utilising state of the art technology
  • Continuous balancing eliminating overflow of coil reducing pumping costs and power consumption
  • Eliminate the need for manual balancing valves, thus reducing the installation and commissioning costs and time
  • Ensure circuits are properly balanced, so tenant improvements and building expansion projects proceed smoothly without impact to other spaces

Facility Managers

ICON_facility-manager

Higher energy prices combined with costly building inefficiencies are making your job more and more difficult to perform. While you should be looking for new and innovative ways to reduce energy consumption and improve facility performance, you’re simply too busy dealing with employees, troubleshooting technical issues, and trying to combat costly problems with more money. Pressure Independent Valves can:

  • Enable you to maintain the correct glycol concentration; increasing overall heat transfer and pumping efficiency
  • Reduce pumping and chiller/boiler operating costs by increasing chiller plant efficiency
  • Reliable operation and occupant comfort with increased building performance
  • Ensure coils are dynamically balanced providing True Flow control
  • Flow is adjustable and always perfectly balanced
  • Offer easy installation in tight spaces
  • Fast delivery and online technical

ESCO

ICON_esco

You are tasked with communicating to organisations how they can save energy and improve performance — but key opportunities are passing you by. Why? Most of your time is spent searching for new product innovations that are backed by proven and reliable energy savings data. Belimo’s pressure independent valves can:

  • Provide advanced solutions for clients incorporating cloud based analytics to benchmark and optimise system performance
  • Eliminates costly problems associated with low Delta T syndrome
  • Recommends Delta T and flow set points via cloud connection to save time and improve efficiency
  • Graphically illustrate performance reports showing current and historical data of flow rates, energy usage, Delta T, and other points of interest
  • Continuous balancing eliminating overflow of coil reducing pumping costs

Commissioning Agents / Balancing Contractors

ICON_commissioning

The responsibilities of your job are complex. Between managing and reviewing projects, along with balancing and commissioning systems, you’ve got a lot on your plate. What you’re really looking for is an innovative product with proven energy savings data that meets your facility’s specifications without the hassle of a complex installation and/or costly maintenance requirements. Belimo’s pressure independent valves can:

  • Easily save settings from one valve configuration and load in another allowing for fast and accurate integration
  • Perform the function of a dynamic balancing valve and control valve in one unit; therefore the flow characteristic and operation of the valve is not distorted in the system
  • Ensure circuits are properly balanced, so tenant improvements and building expansion projects proceed smoothly without impact to other spaces
  • Eliminate costly problems associated with low Delta T syndrome
  • Maintain flow set point regardless of differential pressure variations with its powerful algorithm that modulates the valve based on its measured True Flow
