Presentation Transcript


  • HVAC/R specialized (17 years)

    • Needs are different

    • Minor market for our competitors

Adolfo wurts
Adolfo Wurts

  • BSME from Cal Poly Pomona

    • Specializing in HVAC/R

  • Fieldpiece Employee for 6 years

  • Spoken with 100s of HVAC professionals

  • Developed Field Guide based on direct HVACR technician input

Fieldpiece products
Fieldpiece Products

  • New product ideas come from HVAC technicians

  • Measure success: make the HVAC/R tech’s job easier, faster, safer, and/or better

  • Result: Fieldpiece is the leader in HVAC/R

Fieldpiece parameters tested
Fieldpiece Parameters Tested

  • Test most HVAC/R parameters

Modularity example superheat
Modularity Example: Superheat

  • ARH4 to get Target Superheat

  • ASX24 to get Actual Superheat

Trends increased attention to conservation
Trends: Increased Attention to Conservation

  • Increased attention to conservation

  • Nobody wants another power plant

    • Not the government

    • NIMBY

    • Not the power companies

Trends large portion of energy going to hvac
Trends: Large portion of Energy Going to HVAC

  • 11.1% of US electricity costs are for HVAC (residential and commercial, DOE 2001 data)

    • This doesn’t count combustion for heating

  • Huge energy savings potential

Trends higher seer mandates
Trends: Higher SEER Mandates

  • High SEER equipment being installed

  • Most A/Cs running at 50-80% of rated efficiency

  • High SEER systems are more complicated

Trends government s increased interest
Trends: Government’s Increased Interest

  • Title 24

    • CA standard for AC service

    • Superheat chart

    • Target evaporator exit temperature

New fieldpiece products to improve efficiency
New Fieldpiece Products to Improve Efficiency

  • Superheat and Subcooling heads

    • Evolution of products

  • AOX2 combustion check

Benefits of modularity
Benefits of Modularity

  • One Display and many accessories

    • Use DMM functions (Hold, min/max, etc.)

  • Easy to inexpensively expand

  • Use it your way

    • Stick meter

    • Electronic handle

    • Data logger

    • Remote it

Bright idea field guide
