18 ACR Show Preview A-Gas promotes evolving product portfolio (D24)
LEAK DETECTION, high temperature welding gases and new refrigerants will be the main focus for A-Gas at ACR 2014. With the F-Gas regulations placing an ongoing emphasis on leak reduction, A-Gas has introduced a leak detection product known as Trace-A-Gas. Up to 100 times more sensitive than a leak detection spray, this 5% hydrogen and 95% nitrogen mixture will enable engineers to locate even the smallest of leaks. Oxygen and acetylene, branded as Braze-A-Gas, is an engineer’s preferred choice for brazing of refrigeration and air conditioning systems.
Oxy-Acetylene together, provides a flame temperature of approximately 3500°; a flame significantly hotter than
propane, propylene and MAPP gas and provides good localised heating with minimal wasted heat.
On Stand D24, A-Gas, working in partnership with Honeywell, will also be showcasing the low GWP refrigerant Genetron Performax LT.
Also known as R407F, this medium and low temperature environmentally friendly replacement for R404A and R407A can provide energy savings and carbon footprint reductions.
A-Gas is a market leader in the supply of refrigerant and service gases. Visit stand D24 for technical support and advice on retrofit gases, next generation refrigerants or for more information on A-Gas’ evolving product portfolio.
Shaping compressor technology (D40)
CUSTOMERS ARE increasingly demanding compressors that deliver high energy efficiency, facilitate close control of the system and exploit the benefits of non traditional refrigerants.
Bitzer’s exhibits at the 2014 ACR Show, stand D40, meet these needs, shaping the thinking of specifiers, end users and contractors.
CSVH Screw Compressors feature intelligent application control software, helping to provide one of the most energy efficient compressor solutions available for liquid chiller, heat pump and air conditioning applications. The new Ecostar plug and play condensing units include New Ecoline compressors. More versatile control software allows adjustments to be made
to the system’s operation for maximum energy efficiency. New Ecoline compressors themselves feature infinite capacity control so that operation can be closely matched to actual cooling requirements.
Versions for use with propane are now available.
The potential for using CO2 in commercial refrigeration
systems is realized by Bitzer’s
CO2 Octagon compressors for transcritical applications.
Scroll Orbit 6 Series compressors are particularly suitable for air conditioning systems and heat pumps. The Orbit 8 Series for R410A offers outstanding
efficiency, smooth running and very low operational sound levels.
For refrigerated transport, Bitzer’s new Roadstar compressors, designed for mobile air conditioning applications, are available as four-or six-cylinder compressors.
A cut BlueDiamond above the rest (B10)
CONDENSATE REMOVAL pumps can be an installer’s nightmare. A reputation for being awkward to install and unreliable often dictates the buyer to choose the cheapest item and regard it as a throw away item.
The BlueDiamond range offers a new approach to efficiently, quietly and reliably removing condensate.
With low cost comes poor reliability and a bad reputation for the installer. If a mini pump has stalled or clogged the call-out charge and warranty claim will eliminate any initial savings made. The main weakness of a peristaltic is the tubing which demands regular replacement/maintenance as it will perish and leak after a short time.
ACR News January 2014
The boxy type design is too bulky to be fitted into trunking limiting the installation and servicing possibilities. The motor speed reduction gearboxes wear in use and failures are common. Unlike other condensate pumps which require regular servicing of split peristaltic tubes, worn gear boxes and call-outs to stalled or clogged min pumps the BlueDiamond range has a revolutionary pumping principle, based on our revolutionary patented rotary diaphragm pumping principle.
Proven in service for over 15 years the principle overcomes problems such as
contaminated valves, stuck pistons, split tubes and noisy gearbox motors. An inherently reliable range, it is backed by a three year warranty.
