Next month’s HVAC market show in China is possibly the world’s largest, organizers say, and an Oklahoma-based maker of HVAC construction switches and sensors will be there.

Wilspec Technologies announced it will be at booth No. W1E28 April 8-10 at the Shanghai New International Expo Center during the International Exhibition for Refrigeration, Air-Conditioning, Heating and Ventilation, Frozen Food Processing, Packaging and Storage.

Organizers are calling it the “CRH show.”

Wilspec President and CEO Larry Wilhelm said he believes the show is an important one for his HVAC construction components company.

“With the increased globalization of air conditioning, heat pumps and refrigeration, as well as the emergence of a more sophisticated, more particular consumer base in Asia, we believe participating in the CRH show is absolutely critical to our long-term success,” Wilhelm said. “Additionally, the exhibit has increasingly been a showcase for industry innovation, and we are very excited to present our latest product development and technology to the market.”

More than 50,000 attendees 30 countries and 1,200 exhibitors are expected, officials said.
