Frequently Asked Questions
What does a Pressmatic do?
The Pressmatic re-pressurises the water in any heating or chilled water application. Pressmatics are used wherever there is a need to maintain the fill pressure in both sealed heating and chilled water systems.
What applications does Pressmatic cover?
A solution is available for all installations, from the small ‘retrofit’ market to large commercial and industrial applications.
Installing the correct expansion equipment with Reflex deerators and dirt separators will prevent the sick installation syndrome affecting your project.
How many Pressmatic models are there?
There are six standard options for a pressurisation unit to suit all applications. Selection is based simply on your requirements, i.e. whether you require a basic unit, single pump, twin pump unit with BMS facilities, digital unit etc.
All the pressurisation units featured are designed for installation with our range of Reflex fixed air cushion or Reflexomat variable volume expansion vessels.
Correct selection of the expansion vessels is the key to problem-free system operation and our technical sales staff will be pleased to assist you in expansion vessel selection.
