FAQ
Heat Transfer Solutions — Common Questions
Answers about our products, ASME-compliant manufacturing and US-based support.
What types of heat exchangers does ZILONIS PRE-heat manufacture?
We manufacture shell & tube, gasketed plate, brazed plate, welded plate and plate & shell heat exchangers, along with electric process heaters, ASME pressure vessels and fully custom-engineered heat transfer solutions for North American industry.
Are your heat exchangers built to ASME standards?
Yes. Our pressure equipment is designed and built to ASME Section VIII Division 1 standards for safety, quality and regulatory confidence in the US market.
Where are your heat exchangers manufactured?
Our equipment is engineered with German expertise and manufactured locally in the United States at our facility in Oostburg, Wisconsin — reducing lead times and import risk for North American customers.
Do you offer replacement or retrofit heat exchangers?
Yes. We supply direct replacement and retrofit heat exchangers for most brands and configurations, often with improved performance and shorter lead times than the original equipment.
Which industries do you serve?
We serve oil & gas, chemical processing, power generation, industrial manufacturing, data centers, food & beverage, pharmaceutical and renewable energy across the United States and Canada.
