Product Selection

Select the Correct Product. Every Time.

For some products, engineering selection is required to select the right product with the right performance. Now sales teams can select, price, and quote in one integrated solution with eRep’s engineering selection module.

eRep makes it easy for your sales teams and consultants to make equipment selections themselves. This gets answers to customers faster for more sales.

Selection Engine Tour

See an example of how selecting complex HVAC equipment is made easy using eRep.

Behind the scenes are heat transfer, fan curve, motor, pressure drop, noise, and electrical calculations to meet code requirements.  No matter how complex you think it is, we can deliver it online.


Many of our manufacturer customers used to do all the engineering selections in-house at a tremendous labor expense.  They thought their process was too complex for the sales teams.  Now, they dominate their markets.



Over 15,000 engineers using eRep to select Chillers, AHUs, FCUs, Fans, Coils, Valves, Piping, VAVs, ductwork, and much more.  Lets face it – we are experts at doing selection program for HVAC manufacturers.



Pumps, valves, piping, controls, demand, heat transfer, boilers, accessories.  These products all involve calculations and selection optimization to get the best product to meet the design requirement.


Heat Exchangers and equipment that use HX are no problem.  We can implement your DLL, your vendor’s DLLs, or we can provide HX DLLs already integrated with eRep Selection Module.


The customer knows how many packages to be produced in a hour and what voltage they have available.  Calculations are needed to determine that and the total amp draw, then suggest the modules to meet those conditions.

We turn your selection process into a thing of beauty

Having an online engineering selection tool for consultants gives your company a competitive advantage.  Having it integrated with configuration pricing makes your sales teams the one to beat.  Contact us and we will show you how for your products.
