On-site trials: Low-risk approach to proof of concept
HRS Heat Exchangers has developed a range of trial units, allowing clients to test a variety of equipment including tubular and scraped surface heat exchangers, pilot evaporation plants and mobile piston pumps. Matt Hale, international sales & marketing director, explains more

There’s nothing like seeing the results with your own eyes in order to tell whether a trial has been successful.
Trials may be performed to test the effects of changes in production technique on existing products, as part of new product development and approval, or to see how new equipment and machinery will perform.
The HRS Asepticblock Mini Series allows manufacturers to produce new trial products involving pasteurisation and aseptic packing without the expense or wastage that can accompany full-scale trials. The Asepticblock Mini Series enables production of a full-scale final pack from as little as 20kg of product.
The HRS BPM Series of reciprocating, positive-displacement pumps is a mobile version of the standard BP Series pump, mounted on a mobile skid unit for easy movement, allowing it to be used across multiple production lines and locations.
The modular nature of many HRS heat exchangers means that we can also provide trial units of many of our heat exchanger models. Recent examples using trial versions of the HRS R Series of scraped surface heat exchangers have included a chocolate manufacturer, cheese producer, a jam factory, and for wax production. In each case, mounting the trial heat exchanger and relevant controls on pallets or a purpose-designed skid frame made them easier to move around production facilities, for example to investigate the use of different lines.
Investing in any new processing equipment not only represents a significant capital outlay, but results in inevitable disruption during installation. However, by trialling equipment prior to investment, both users and manufacturers can be sure that the best solution has been chosen.
