Jeremy Olberding


Jeremy Olberding graduated in Mechanical Engineering at the University of Idaho.  Jeremy is the Vice president of sales for Colmac Coil where he has worked for 15 years and held several positions including research and product development engineer.  Today Jeremy is responsible for design and applications engineering group  focusing on Ammonia and CO2 for industrial refrigeration projects.

Jeremy Olberding will be presenting on the use of low charge direct expansion in low temperature industrial ammonia refrigeration applications. This technology reduces the first cost of installation while significantly reducing the ammonia charge required on the site. A review of recent installations using low charge direct expansion in industrial refrigeration systems will be discussed showing benefits including faster defrosting, effective operation at multiple temperature levels, good response to changes in load, fast restart after power failure, and simplified maintenance and operation through elimination of recirculation pumps.  The DX ammonia piping handbook will also be covered to provide design guidelines, and example P&ID’s for designing DX ammonia systems.
