About Napps

NAPPS is an engineering driven manufacturer of highly efficient Liquid Chillers, Water Cooled Condensing Units and Compressor Units.  With more than 50 years of experience in all phases of the HVACR industry we are committed to developing and manufacturing products that are highly efficient, reliable, serviceable and cost effective.

After each new NAPPS product is envisioned, it is modeled using complex NAPPS performance software before the design is completed and the first article is produced. Once the desired performance is realized using the modeling software, the preliminary design is finalized and the first article is produced. The first article is extensively tested in the NAPPS test facility where actual performance, throughout the full operating range, is tested and compared to the software results. When the desired performance and reliability is demonstrated, the final design is created. Then a unit with all final design features is returned to the NAPPS test facility for onsite safety certification by the Environmental Testing Laboratory (ETL). Once complete, the unit is ready to be produced.

The NAPPS test facility is state-of-the-art in design and capable of testing all NAPPS Liquid Chillers in accordance ASHRAE Standard 550/590 Performance Rating of Water-Chilling Packages using the Vapor Compression Cycle. To comply with this standard, the NAPPS test facility was designed to meet or exceed ASHRAE Standard 30-1995R, Method of Testing Liquid Chilling Packages with temperature and pressure instrument accuracy in compliance with ASHRAE Standard 41 Standard Methods of Measurement. Instruments calibration is traceable to National Institute of Standards and Technology (NIST).

The performance testing does not stop after completion of the design phase!  All production Liquid Chillers are also tested for 6 to 8 hours in our test facility before shipment to ensure quality, performance and a smooth start in the field.

NAPPS is committed to the continuing process of product development, introducing new innovative designs while meeting or exceeding complex efficiency and environmental standards.
