Cool-Fit Refrigeration Systems

COOL-FIT is a complete system solution for secondary cooling and refrigeration piping systems. The system is based on the tried and tested ABS plastic system from GF Piping Systems which contains pipe fittings valves and transition fittings, now with the option for pre-insulated pipe and fittings with outer jackets in black. You can adapt the system solution to your particular needs. For example white pre-insulated for food production halls or standard plastic pipe with control valves for pump houses or OEM chillers.

APPLICATIONS:

The system is water and vapour tight. Ideal for the transportation of chilled water, iced water, salt solutions, glycol solutions and organic salt solutions.

ADVANTAGES:

  • Simple and cost-effective installation; reduced costs for pipe hanging
  • No corrosion
  • Top quality and efficient, maintenance-free system
  • Reduced energy consumption as well as resource conservation
  • Environmentally friendly
  • High impact resistance, even at very low temperatures
  • Temperatures are maintained accurately due to low heat conductivity
  • Suitable for outdoor applications: UV and weathering resistant
  • Water and vapor tight
  • You can adapt the system to your particular needs

  • keyboard_arrow_downPlastic Pipe Sizes:

     

    Plastic pipe dimensions are, by convention, specified by the outside diameter, usually denoted by e. This may be supplemented by stating the nominal inside diameter or DN. Sometimes the pipe wall thickness is specified by the SDR or Standard Dimension Ratio.

     

    SDR = d divided by e.

    Where d = the outside diameter (mm)

    Where e = the pipe wall thickness (mm)

  • keyboard_arrow_downWhat Pipe Size?

     

    The pipe size can be calculated as follows:

    di = 18.8 √Q1 ÷  v

    Where:

    di = Inside pipe diameter (mm)

    Q1 = Flowrate in m3/h

    v = Flow velocity, usually 0.5 to 1.0 m/s for suction lines

    OR

    1.0 to 3.0 m/s for discharge lines.

  • keyboard_arrow_downPressure loss in straight pipe:

     

    A rough calculation of pressure loss in straight length plastic pipe can be done using,

    Δ Pr = λ × (L ÷ di) × (ρ ÷ 2.102) × v2

     

    Where:

    Δ Pr = Pressure loss (bar)

    λ = Pipe friction factor

    L = Length of straight pipe (m)

    di = Inside pipe diameter

    ρ = Liquid density (kg/m3)

    v = Flow velocity (m/s)

     

    For smooth bore plastic pipe: λ = 0.02
