Managing Air Problems in recirculation Systems

Engineering Appliances have more experience with solving air problems than any other company in the UK. In 1988 EA launched the first Microbubble Separator capable of deaerating systems rather than just venting them.

In the last 20 years technology in this sector has made significant advances and the equipment is becoming more sophisticated and efficient. Unfortunately due to their popularity Microbuble separators have been ‘commoditised’ which is leading to incorrect selections and installations.

 For that reason EA have re-launched the very popular CPD on ‘Managing Air Problems in Recirculating Systems’ If you want to book this or any other of our CPDs please contact your local area manager or contact Jamie Bomber on 07976088909

 

The Queen is to formally open London's St Pancras station later following a refurbishment costing £800m.

Work began on transforming the station in 2001 to enable it to accommodate domestic rail services and Eurostar trains to and from France and Belgium.
More than 150 years of dirt has been removed from the brick work and a new roof has been fitted with 18,000 panes of self-cleaning glass.

The front of the station will open as a five-star hotel in 2009.

As part of its refurbishment, the station has been fitted with state-of-the-art technology including Wifi, touch-screen monitors and passenger information screens in all 60 retail units. St Pancras will eventually be five stations in one - housing Eurostar, high-speed domestic services to Kent from 2009, Midland Mainline, Thameslink and six Tube lines.

'Crown jewel'

Developer London & Continental Railways said St Pancras International was the jewel in the crown of a £5.8bn project running over 10 years, bringing high speed rail travel to the UK.

Engineering Appliances were involved from the outset of this prestigious and difficult project and supplied all Expansion Joints, Flexible Connections and Dearators.

EA’s Engineers worked closely with the Costain / O’rourke and Bachy / EMCOR Rail joint ventures to find often innovative solutions to difficult expansion problems in the complex pipe work systems.

WRAS Approved RPZ Valve Testing

With immediate effect EA,s service department can offer commissioning , servicing and testing of all makes of backflow preventers.

These devices are known as reduced pressure zone or RPZ valves for short and are designed to separate the mains water supply from heating and chilled water systems. They are often used as fast fill connections but are used more and more in water make up devices instead of the traditional break tanks. Break tanks store water which can be stagnant for very long periods of time encouraging the growth of Legionella and Pseudomonas bacteria.

RPZ valves overcome this problem but need to be fitted and maintained in accordance with EN1717. The water regulations state (see guidance note here) that written permission is required from the local water authority and that they are commissioned by an approved and certified engineer. The legislation also requires all RPZ valves to be tested on an annual bases. If you have an RPZ vale fitted in your system and you require it to be serviced please call us for a competitive rate.

Kew Seminar ‘The Pressure Is On' Success!!

EA held their first one day seminar  entitled ‘The Pressure Is On’ to design energy efficient long lasting heating and cooling systems at the wonderful Kew Bridge Steam Museum in West London. The day was a great success with almost all places taken up. The keynote speaker of the day was Karl Willemen CEO of Pneumatex AG who has over 20 years experience in pressurisation of heating and chilled water systems.

He covered topics such as calculating correct pre charge and cold fill pressures and the need for an adequate reserve in expansion vessels. He also explained the often misunderstood but vital topics of Neutral Point and Oxygen Diffusion.

The Kew Bridge Steam museum made an ideal backdrop to a seminar on pressure control and all the delegates were especially impressed by the giant 90” Grand Junction Beam engine which ran especially for the delegates on the day. This engine is a fine example of Victorian engineering without compromise or the dreaded ‘value engineering’ ever having been applied.

These were some of the comments we had from the delegates:

‘Just a note to say many thanks for an interesting day at Kew yesterday. Your talks on system cleanliness and expansion have given me something to think about, and I feel we will need to discuss a couple of jobs soon.

The location for the seminar was great, and having the pumps run up, together with the guidance from the museum staff, made it a good day out.’

Once again many thanks

EA launch new water make up device

The new Pleno PI6 is the latest addition to the Pneumatex range of water make up and pressurisation systems. Manufactured in Switzerland the new Pleno PI6.1 and PI6.2 comes complete with the now familiar BrainCube control system. A new design from the ground up the Pleno PI6 has many unique features. It uses high quality multistage pumps which are rated for continues running and a maximum system pressure of 5.4 bar. By selecting a special fill mode it is therefore possible to use the Pleno as a first fill device for systems up to 10,000 litres.

Once the heating or cooling system has been filled the Pleno switches automatically to pressure monitoring. In service the unit has all the usual Fillsafe functionality which measures total make up volume and monitors frequency and running times. If the preset values are exceeded the Pleno will switch off and give an alarm thus protecting the building from leaks and the system from excessive corrosion.

A pressure transducer continuously monitors system pressure in accordance with EN12828 and if the set minimum pressure is reached will make up water via a WRAS approved break tank. Two freely configurable volt free contacts are available as standard to send messages and alarms to any building management system. The BrainCube microprocessor based control unit can also be integrated with level controlled water make up systems such as the Pneumatex Compresso.

Engineering Appliances Changes Ownership

Pneumatex AG of Switzerland has acquired Engineering Appliances from the Andrews Sykes Group. Engineering Appliances is a long established and well-respected name in the HEVAC sector and is best known for its high quality expansion joints, rubber bellows, Deaerators and dirt separators. In January 2004 EA was appointed exclusive distributor for Pneumatex AG adding their range of pressurisation systems to the existing range. With more than 200 employees Pneumatex is Europe's leading manufacturer of pressurisation systems, expansion vessels, Deaerators and dirt separators. Established in 1909 and inventor of the closed pressurised heating system, Pneumatex is an expanding company led by traditional Swiss quality and innovation.

Pneumatex AG manufactures in Switzerland and France and already has subsidiaries in Germany, Belgium, Luxemburg, Austria and The Netherlands.

Since appointing Engineering Appliances as a distributor Pneumatex sales have grown rapidly in the UK. To take full advantage of this important market, Pneumatex wanted to take full control of its distribution channel, which ultimately led to the acquisition of Engineering Appliances. The existing management will continue to run the company and the traditional products including the BOA expansion joints and Stenflex rubber bellows will remain a key part of the product mix.

The takeover of Engineering Appliances coincides with the most fundamental product changes in Pneumatex's history.

Service and Maintenance

A new service

Engineering Appliances have appointed an in-house service engineer to commission, maintain and service our ever increasing range of pressure step degassers and pressurisation systems.

Clive Halliwell is an experienced engineer and has had extensive training in the operation and servicing of Pneumatex systems. We also have many years of experience with Spirovent products and can therefore offer expert service on Spirovent Superiors.

In addition to commissioning, Engineering Appliances offer annual service contracts with reduced call out charges in case of a breakdown.

Although Pneumatex systems and vessels are renowned for their quality keeping your pressurisation and Deaeration equipment serviced ensures that they continue to protect your system from corrosion, system sludge and expensive breakdowns for many more years. Engineering Appliances only use original parts when repairing or servicing Pneumatex equipment.

 

New CPD

Engineering Appliances has added a new presentation to it's range of CPD's. It is entitled 'How correct pressure control prevents the Sick System Syndrome' and looks at the prevention of corrosion in heating and chilled water systems. The CPD covers pressurisation, correct sizing of expansion vessels, reducing water make up and also pressure step degassing.

Major Contracts

We are proud to announce that AMEC chose Engineering Appliances as the sole supplier of Pressurisation Systems, Degassers and Expansion Joints for the massive Heathrow Terminal 5 project.

AMEC opted for the Pneumatex systems because they can easily cope with the very large expansion volumes while keeping pressure changes within tight tolerances. The chilled water system is controlled by a compressor driven pressurisation unit while for the heating system a pump controlled 'Transfero' unit has been selected. Both systems will be kept free from air by several VMB Pressure step spray degassers.

EA have been involved from the outset in assisting AMEC with pipe work expansion design and are the sole supplier of multi-ply stainless steel expansion joints.
