Does it matter how far away the silencer is from the blower?

The answer varies, depending on the type of heat exchanger. For a shell and tube, hairpin, or a plate heat exchanger, we will need the following information:
Five of the following:
– Warm fluid inlet temperature
– Warm fluid outlet temperature
– Warm fluid flow rate
– Cold fluid inlet temperature
– Cold fluid outlet temperature
– Cold fluid flow rate
– Each side of the exchanger needs at least two values from the above list. – Or, heat load and four values from above list (Again, need two values from each side.)

Is Chicago Power & Process, and the principals you represent, familiar with CRN and PED requirements?

Yes. Chicago Power & Process has worked on many heat exchangers that required CRN (Canadian Registration Number) approval or European PED (Pressure Equipment Directive) certification. Approval can usually be obtained within the normal shipping schedule, but there can be delays, especially for brazed aluminum units, due to the complexity of the approval process. Contact us as early as possible in your project, if CRN or PED will be required.

What information is needed to size a heat exchanger?

The answer varies, depending on the type of heat exchanger. For a shell and tube, hairpin, or a plate heat exchanger, we will need the following information:
Five of the following:
– Warm fluid inlet temperature
– Warm fluid outlet temperature
– Warm fluid flow rate
– Cold fluid inlet temperature
– Cold fluid outlet temperature
– Cold fluid flow rate
– Each side of the exchanger needs at least two values from the above list. – Or, heat load and four values from above list (Again, need two values from each side.)

  • Allowable pressure drop for both fluids
  • Inlet pressure if fluid is a gas
  • Property data: We have a large data base of property data, but you may need to supply data for a proprietary fluid. Generally, we need thermal conductivity, specific gravity (or density), specific heat, and viscosity, at 2 points ­ 1 above the maximum temperature for each fluid in the exchanger, and 1 below the minimum temperature of each fluid.
