About Coilmaster Research and Development

R&D Lab Overview

Commissioned in 2010, this coil testing facility is centered on a 20-ton psychometric chamber. The test facility allows the engineers at Coilmaster to test every type of coil we produce, under all types of conditions, and with a wide range of fluids. This extensive testing results in reliable coils with exceptional performance.

Our 20-ton Psychometric Test Chamber Capabilities Include:

  • Airflow Range Chamber dry bulb temperatures from -10°F – 130°F
  • Chamber capacity Chamber capacity up to240,000 Btu/hr
  • Humidity Range Chamber relative humidity between20% and 95%
  • Water inlet temperature Water inlet temperature range38°F – 190°F
  • Glycol temperature range Glycol temperature range from20°F – 200°F
  • Steam inlet pressure Steam inlet pressure range of1 – 10Psig
  • Airflow Range Airflow from200-8000 SCFM
  • 10 Ton Capacity Condenser Capacity up to10-Tons(R410a)
  • POE Compatible Refrigerant Any POE compatible refrigerant(R410a, R404a…)



VirtuaLab® allows the engineer to answer the quintessential question: what if? This simulation package will help replace some in lab testing with the virtual simulations, hence the name.

About VirtuaLab®

Coilmaster has created a proprietary suite of simulation tools that enables engineers to move beyond standard coil selection software. A detailed tube-by-tube heat exchanger model is the heart of the suite allowing detailed circuiting and airflow distributions to be modeled. The coil simulators allow for variable air flow patterns, dropped tubes, tapered circuits, and even has a qualitative transient frosting model. This detailed coil analysis is incorporated in the extremely flexible system simulation tool. By allowing vapor compression systems to be created via drop-and-drag the system simulation tool is capable of calculating performance on nearly any type of system.

Some Key Features of VirtuaLab®

Annotated Explanation of VirtuaLab®
A. VirtuaLab® allows multiple fluids to be simulated including R410a, R22, R407C, R404A, R507A, CO2 evaporation, Propylene Glycol, Steam, and Water. Both evaporation and condensation can be modeled using several input and output options. B. The heart of VirtuaLab® is the tube-by-tube model that allows a wide range of circuiting options. VirtuaLab is capable of simulating dropped tubes, tapered circuits, integrated sub-coolers in evaporators, and multiple slab coils. C. Because real world coils rarely see uniform velocity, VirtuaLab® offers the user the ability to specify a different velocity profile for the inlet and outlet. Choose from pre-defined profiles including uniform, linear, exponential, parabolic, duct flow, or an inclined coil profile; or you can create your own profile using our custom profile tool. D. There are numerous ways to view the solution data with VirtuaLab®. The user interface will show the overall performance with the traditional outputs found in most software packages. However, it is possible to dig a little deeper into the coil performance by using the plotting tools. E. With the plotting tools you can look at each tubes performance for leaving temperature, pressure, quality, fluid velocity, or enthalpy1. It is also possible to view the performance of each circuit. Either option will provide additional insight into coil performance that will allow a coil to be designed to better match your application. 1. a thermodynamic quantity equivalent to the total heat content of a system. It is equal to the internal energy of the system plus the product of pressure and volume.
