Pressurisation Unit Services
One supplier for the kit that keeps sealed systems at the right pressure: pressurisation units, booster sets and expansion vessels.
Sealed heating and chilled water systems rely on a pressurisation unit and expansion vessels to keep pressure stable. When they fail, boilers lock out on low pressure, or relief valves lift on high pressure.
We design, supply, commission and repair the lot. That includes checking vessel pre-charge, servicing pumps and pressure switches, and making sure vessels fall within a written scheme of examination where the Pressure Systems Safety Regulations apply.

FAQ
Questions we get asked
Why does our boiler keep locking out on pressure?
Often it's a failed expansion vessel membrane or a pressurisation unit fault. Both are quick to diagnose.
How often should our equipment be serviced?
At least once a year. Ideally heating in autumn and air conditioning in spring. Oil-fired equipment really should be cleaned and serviced every year.
Why service if nothing is wrong?
Better reliability, problems caught early, lower running costs, longer equipment life and a safer building. It's also usually a legal requirement.
