Scott Davies, UK sales director for JAVAC UK, explains why the VETO Pro Pac Tech Series are the tool bags to have in your van in 2019.

Every tradesperson knows the difference a great quality tool bag can make when it comes to carrying valuable tools to and from jobs. Make the wrong choice and you could end up with an uncomfortable, badly made bag which just doesn’t do what it promised - often an expensive mistake to make. 

Student engineers at Bath College have been road testing a new range of precision hand tools from JAVAC.

The JAVAC Edge tools are constructed from lightweight, high-grade aluminium and feature time-saving features which JAVAC says are inspired by engineers, making them perfect for professionals on site

The range includes a multi size tube expander set, the only set available with a ¼” expander head. The tube bender features a unique dual hinge design which resets the handle position for extra leverage, making the second bend to 180° simple.

Introducing the new Refco wireless and Bluetooth-enabled digital TAP (Temperature and Pressure) gauge set from Javac. 
 
The TAP gauge set is an ergonomic and user-friendly instrument, capable of measuring both temperature and pressure from the high and low sides of refrigeration and air conditioning systems.
 
The set features a digital pressure gauge that connects directly to the system. The gauges come with a built-in library of over 50 different refrigerants, making the Refco TAP a highly versatile piece of equipment.

​The versatile Javac Altima-A2L recovery unit is designed to meet the needs of engineers in a changing environment.

With the F-Gas regulations now in full effect, there are serious repercussions for the HVAC industry. Engineers may now be aware that R32 made up 50% of the existing R410A refrigerant found in many current air conditioning systems. As R32 becomes more and more common, it is vital that engineers have the correct tools to safely and efficiently do the job. The Javac Altima-A2L has been specially designed to recover R32 and A2L gasses.

The Javac tube straightening tool has been designed for the air conditioning, refrigeration, plumbing, heating and ventilation industry.

The tool is available in four sizes,1/4,3/8,1/2,5/8, and is the first efficient hand-held straightening tool which easily and accurately straightens tubing and piping from coils and cables.

Lifting bulky or heavy pieces of equipment to ceiling height prior to install is a critical health and safety consideration these days. Two people lifting and fixing pieces of equipment from step ladders is not best practice, especially when there is now a better solution available.

The REFCO LFT-230 lifter is a portable electric hoist that will lift and position various pieces of equipment, such as ceiling cassettes or outdoor units, ready for fixing. At 20kg the lifter only requires one person to carry and assemble straight from its carry bag. Once in position, it can easily be slid to exactly where it’s needed. Assembly is quick and easy. The top of the mast has a built-in spirit level and when this is central the four legs simply drop out to meet the floor; this creates an incredibly stable structure. The lightweight tubular steel platform rotates freely and standard ratchet scraps can be easily attached, if required.  
  
Once the piece to be lifted is placed on the platform, the operator can step back from the unit and control the lift with the long lead and variable speed handheld controller. This provides a safe working area round the unit with full view of the lift and helping to avoid potential collisions, especially in confined spaces. When the piece is located safely, the operator can then work from a step ladder and while still using the controller, can make micro adjustments before fixing.

The LFT is not limited to just lifting. It can support or stabilise ductwork prior to inspection. It’s also idea for supporting lengths of cable tray and pipe work before fixing.

Dave Kingston, Javac UK Sales and Technical Manager, introduces the VG64 Digital Vacuum Gauge (series 2).

​​Javac supply the all-new VG64 digital high vacuum gauge. The VG64 series 2 comes with a lifetime sensor and two-year warranty, so the engineer can rely on this instrument with confidence.

With any electronic sensor-based gauge there is always risk of contamination, but even if it is soaked with oil and other contaminants, the accuracy of the VG64 may only drop by 5% at the most. If the sensor requires cleaning, the unit will display “SERR” and in this case simply cap one end of the tee piece and fill the other with alcohol. Soaking overnight is certainly an advantage and should return it to new condition. 

When connecting to a system, the best results are achieved by attaching to a port furthest away from the vacuum pump. The highest concentration of molecules under vacuum must always be found the furthest away from the pump and the more molecules, the higher the pressure. If it is necessary to connect using refrigeration hoses then allowances must be made for out gassing, as hoses are naturally subject to contamination.

The gauge resolution increases the deeper the vacuum, but as with all electronic gauges they don’t come on scale until 80% pump down has been achieved. In the case of the VG64 this is 19 mbar and depending on temperature this is where dehydration starts to take place.

As well as the standard hanger the VG64 has the all-new HVAC magnetic strap which attaches to all ferrous surfaces. In the manifold gauge hanger style, it is a fantastic addition to any engineer’s tool kit.  

​Now available in both 2 valve and 4 valve, boasting a smaller compact design and sturdy housing in comparison to its predecessor. The improved robustness paired with its impressive functionality really does make it make it a must have for any engineer.
