Airedale International recently selected R32-based Bitzer Orbit 8 scroll compressors for its latest generation of Azure DeltaChill chillers. It reports an estimated 7% increase in European Seasonal Energy Efficiency Ratio (ESEER) compared with its previous R410A range. Airedale ran comprehensive tests on prototypes with various compressor options. Bitzer supported the development team with access to advance performance data for the refrigerant and visits to the company’s UK research and development facility by James Cullen, global director scroll product management. Tests were carried out at standard and extreme rating conditions of the operational envelope, as well as other tests for ESEER, Ecodesign SSCEE, oil return tests in worst-case conditions and high and low supply water
temperature.The supply of special compressors fitted with oil sight tubes, enabled the development team to monitor conditions within units during testing.
Waterloo Air Products has promoted Andy Wardle to the position of sales director, with a seat on the company board.
Mr Wardle joined Waterloo in 2005 as area sales manager, having previously gained valuable sales and industry experience at both TROX and GDL. As his career within Waterloo developed, he
progressed to regional sales manager for the North before taking on his most recent role as head of national sales.
As sales director, Mr Wardle will be tasked with developing Waterloo’s continued growth strategy while leading the national sales team. Commenting on his new role, Mr Wardle said: “I’m delighted to join the Waterloo Board and look forward to using my wider commercial knowledge to drive market expansion with the support of our fantastic sales team.”
Waterloo’s managing director, Russell Shenton, said: “We would like to congratulate Andy as we welcome him to the Board of Waterloo. During his time with Waterloo, Andy has demonstrated an expert knowledge of our products and core technology backed by strong people and leadership skills.

Armaturenwerk
The AWA OLC provides optimum oil levels in refrigeration compressors and can be used in compound systems with reciprocating or scroll compressors. Its functionality is based on variable level
measurement by means of an electronic float sensor. It can be used in systems of up to 120 bar for a variety of refrigerants and oils. The speed of level change is also measured.
Other features of the OLC include a large sight glass, an LED display on the front and a modular adapter system. The installation dimensions enable plant engineers to design more compact plants. The power ON Logic and the emergency injection protect the refrigeration compressors.
The AWA OLC regulates its oil quantity to a level of 40% to 60%. If the value falls below the normal range, a delay counter is activated. This prevents the system from swinging up and the compressor from overfilling. If the oil level drops below the critical range despite active filling, an alarm counter starts which switches an alarm relay after 80 seconds.
