Danfoss was planning to introduce three new innovations at the 2020 IIAR Natural Refrigeration Expo next week.

Unfortunately the event was postponed due to the coronavirus (COVID 19). 

The IIAR Conference had been scheduled to take place March 15-18 in Florida, the United States but this changed after the World Health Organisation (WHO) declared the virus was a worldwide pandemic. An email was sent to exhibitors from IIAR president, Dave Rule.

He said it was a difficult decision to cancel the conference this year but the health and safety of attendees is their primary concern.

Danfoss announced plans to showcase a complete integrated evaporator control panel, semi-welded plate heat exchanger, and digital gas detector. 

These products are the newest, most advanced components from Danfoss' industrial refrigeration solutions, which blend hardware with software to create customizable intelligent, energy efficient, and cost-effective systems. 

Danfoss said its advancements in innovative, custom integrated control solutions enable stronger, more intelligent distributed and central systems controls for industrial refrigeration systems.

“These technologies increase energy efficiency, ensure food safety, and help refrigeration systems transition to alternative, climate-friendly refrigerants,” the company said.

“Available for new or retrofit projects, our complete integrated evaporator control panels are factory-programmed and configured to your specific application and support multiple defrost methods, all while controlling flooded and DX evaporators.”

Its ammonia gas detection automatically closes hot gas and liquid feed valves and turns off evaporator fans. Lastly, the panel includes an evaporator microprocessor controller with either a door- or remote-mounted display and is packaged in a custom enclosure specific to its appropriate environment.

Danfoss will also introduce its SW19-59 range of semi-welded plate heat exchangers, which are specifically designed, crafted, and tested to fit ammonia-based industrial refrigeration applications.

The SW19-59 range offers outstanding thermal performance due to its optimized plate geometry that supports high turbulent flow, enabling a compact design and lower charge.

“Operational safety is essential in ammonia applications, so we engineered a new gasket system to ensure high gasket stability and optimal plate alignment, enabling fast and easy installation, service, and maintenance while preventing gasket-blow out,” the company said in a statement.

“Furthermore, the risk of contamination is reduced due to the glue-free, double-gasket barrier that will drain potential leaks outside the plate pack.”

Danfoss will showcase its digital gas detectors and sensors which are precalibrated to match specific refrigerants, applications, and safety requirements, ensuring a safe and regulation-compliant system.

With a comprehensive set of safety features, basic to heavy duty Danfoss digital gas detector models offer improved accuracy, simplified operator handling, automatic self-diagnostics, password-protected alarms, and a smart calibration process that rejects sensors with low life-expectancy.

Collectively, these features minimize risks based on system settings, calibration, and service errors for continuous safety.

For the first time ever, the digital gas detectors will be on display in a harsh weather habitat to demonstrate their durability and environmentally-resistant performance.
