CoilPro

Allows accurate selection and/or rating of plate fin and tube (compact) heat exchangers for commercial and industrial HVAC, refrigeration, and process heating and cooling applications. Calculations normally assume air on the finside, however, the program allows entry of gas properties in the case of special gases on the finside. State-of-the-art fluid property routines are used to calculate properties of various single and two-phase tubeside working fluids including:

Aqueous (single phase) Solutions

Water, Ammonia, Calcium Chloride, Ethanol, Ethylene Glycol, Glycerol, Lithium Chloride, Magnesium Chloride, Methanol, Potassium Acetate, Potassium Formate, Propylene Glycol, Sodium Chloride

Viscous Fluids

Oils

Volatile (two phase) Refrigerants 

Water (steam), Ammonia (NH3), Carbon Dioxide (CO2), Nitrogen, Propane, Iso-Butane, R12, R123, R124, R125, R134a, R142b, R152a, R22, R23, R245fa, R32, R401a, R404a, R407a, R407c, R417a, R500, R502, R503, R507a, R508b

Commercial and industrial HVAC and refrigeration cooling coil calculations can be made for either chilled water or evaporators (DX, pumped, and gravity flooded), with or without dehumidifying on the finside. The program uses thermodynamically correct psychrometric calculations from cryogenic (below 100C) to very high (above 100C) air temperatures.

Calculations with two phase condensing fluids on the tubeside, such as steam, are available along with single phase cooling of tubeside fluids (air heating on finside).

The program allows the user to select from a wide range of tube diameters including: 5/8" (15.9mm), 7/8" (22mm), and 1" (25.4mm), in a wide range of tube materials including: cupro-nickel, carbon steel, stainless steel, and aluminum. Fin thicknesses available include: 0.008" (0.20mm), 0.010" (0.25mm), 0.012" (0.31mm), 0.016" (0.41mm), 0.020" (0.51mm), and 0.032" (0.81mm).

Casing materials include 5052 (AlMg3) Aluminum, Galvanized Steel, 304 or 316 stainless steel.

The software runs online through the user's internet browser via a secure username and password. In addition to calculating thermal performance, the program calculates a price and generates dimensional drawings and specifications.

Access to CoilPro is available to authorized Colmac Coil representatives and qualified customers.

 

Dryware

Colmac Coil parametric Dryware selection software creates dry cooler, condenser, and gas cooler custimized designs simple and fast. All available online in our browser-friendly software.  A wide range of working fluids along with various materials of construction and options are available right in the software including:

Working Fluids Available for Condensers: 

Acetone (propanone), Ammonia (R717), Benzene, Butane, C02, Cyclohex, Cyclopro, Ethane, Heptane, Hexane, Isobutan, Methane, Pentane, Propane, R113, R114, R12, R123, R1234YF, R125, R134A, R142B, R152A, R22, R245FA, R32, R401A, R404A, R407A, R407C, R407E, R407F, R410F, R413A, R448A, R449A, R500, R502, R503, R507A, R508B, Toluene             

Working Fluids Available for Fluid Coolers:

Calcium Chloride, Ethylene Glycol, Potassium Formate, Propylene Glycol, Special Fluid, Water       

C02 is now available in Colmac Coil Supercritical Gas Coolers 

Air-cooled ammonia condensers in very large capacities can also be selected with stainless steel tubes.

The software is designed to allow the user to either select or rate air-cooled condensers and dry (fluid) coolers. Choosing the Select method presents you with a range of models which meet the capacity requirements you have specified. Choosing the Rate method allows you to calculate capacity for a particular condenser or dry cooler model at the operating conditions you specify.

Selections can be sorted to any criteria, such as:

  • First Cost
  • Energy Efficiency
  • Sound Level
  • Refrigerant Charge 
  • Weight 
  • Dimensions 

 

In addition to calculating thermal performance, the program calculates a price and generates dimensional drawings and specifications.

Access to Dryware is available to authorized Colmac Coil representatives and qualified customers.
