The first commercially successful plate and frame heat exchanger was introduced in 1923 by Aluminum Plant and Vessel Company Ltd., which became known as APV. We have evolved and grown over the years to better meet the changing needs of our customers and their industries. Our vision for the future is rooted in a long standing tradition of excellence and commitment to progress. We strive to offer the customer the highest quality products and services today, tomorrow and beyond.
APV ParaTube (tube-in-tube heat exchangers) can be supplied with either straight tubes or corrugated tubes. They all follow a similar construction format with a single tube or number of smaller tubes enclosed within an outer shell. They are available in the four configurations and can be manufactured as a fully-welded design, with removable end caps or with built-in thermal expansion protection of O-rings or packing between the shell and tube bundle.
For more than 60 years, Votator scraped surface heat exchangers have been replacing slow, inefficient batching operations with more uniform, controllable and repeatable continuous processing.
