Aria Climate Systems - Some of our clients

One of the biggest headaches facing clients when installing or modifying an air conditioning system is the use of hot works (using a naked flame to braze the pipework connections) taking place in their building.

Aria can remove this problematic issue for you.  Two of the biggest names in the AC industry -  Conex & Rothenberger  - have joined forces to create the ’ >B< MaxiPro’ system.  Instead of using brazing to couple refrigerant pipework, it uses a press system.  Amongst a number of benefits this means no naked flames & no fumes – A massive Health & Safety risk removed.

A standard installation using a naked flame has a number of issues involved:

Documentation – A raft of Health & Safety forms need to be completed to the satisfaction of both the client and installer – something we can both do without, also the first thing to be scrutinised by the Health & Safety Executive and Insurers if there ever is a problem.

Precautions - Fire protection mechanisms need to be turned off in the near vicinity of the works taking place.  This can prove problematic and time-consuming for building control.

Fire Alarms- Even when all precautions have been taken, alarms can go off.  The knock on effect of this is not only the total evacuation of the building, but also the bill when the Fire Brigade turn up to a false alarm.

The >B< MaxiPro System

The system uses a Rothenberger Romax press to create a permanent and secure joint designed specifically for Air Conditioning & Refrigeration purposes.
