CO2-ammoniaUSA: Vilter Manufacturing, part of Emerson Climate Technologies, says it is in the final stages of introducing a range of reciprocating compressors for CO2/ammonia cascade systems.

The CO2/ammonia cascade system extends the capabilities of Emerson’s line of Copeland scroll compressors to offer additional refrigeration applications in food processing, dairy, produce and cold storage warehousing.

As US EPA regulations continue to evolve, Emerson says it sees ammonia as an energy-efficient offering, using waste heat from a facility’s refrigeration system for other heat and air conditioning applications.

Product testing is being carried out at Emerson’s recently opened Helix Innovation Center.

“Leveraging the research and development capabilities of Emerson’s Helix Innovation Center, we developed and are in the final stages of testing a small CO2 cascade solution and building on that product line,” said Thomas Hoopes, director, business development, Vilter Manufacturing LLC.

“Our team is using data from this testing environment with real operating conditions to make final tweaks backed by proven results before going to market.”

The Helix Innovation Center became operational in December and is meant to act as a global hub for HVACR industry education. It is also intended to facilitate a collaborative approach to innovation in the development of future refrigeration technologies.

This smaller CO2 ammonia cascade system, which is expected to be launched in the next few months, will pave the way for the development of larger models for industrial use.
