Engie
Engie Refrigeration will relaunch the air- cooled Pensum Air. The chiller is designed for use in mid-sized office buildings and public buildings. The new Pensum Air uses the refrigerant R454B, which has good thermodynamic properties and a low GWP value. Compared to the previous refrigerant R454B can lower CO2 emissions by 78% without affecting refrigeration capacity. The product already meets the requirements of the Ecodesign Directive for Tier 2. Engie has also refined the design and the configuration of the chiller.
The new compressor makes the chiller even more efficient to run than its predecessor model. It is available in four different lines – Basic Cool, Free Cool, Super Silent and Reversible Heat – with a refrigeration performance between 50 and 400 kilowatts. All Pensum Air chillers feature designs and measures for machine
safety in combination with slightly flammable class A2L refrigerants. They also have optimised measuring, control and regulation technology and improved housing. The Pensum Air also has the option for add-ons ranging from specific configuration packages for different requirements to glycol collecting trays and various warranty and service options.

Hubbard latest Scotsman is the NU H 100. Its airflow in and out is to the front, there’s no need to leave space at the sides or back for ventilation. This, combined with its small size, means it can be fitted into the tightest of spaces. Even so, it can produce up to 56kg of ice per day. The NU H 100 makes half dice ice. These narrow, rectangular cubes weigh 6g and are softer than gourmet ice cubes, and smaller than standard dice cubes, which is why they blend more easily. Their large surface area means they cool effectively and quickly. Undercounter dice ice machines are relatively unusual so they need a certain amount of height. Scotsman developed the NU range in order to meet the demand for dice ice from sites which don’t have space for a high volume, modular dice icemaker. The NU H 100 is very practical. The one-touch cleaning system saves
time and cost, while the air condenser is easy to access for do-it-yourself cleaning. When routine maintenance is due, an alarm lights up on the front panel. The exterior is made of stainless steel, and the storage bin’s one- touch sliding door makes it easy to access the ice.

LG Electronics
LG Electronics has launched one of the industry’s first 4, 5 and 6 HP R32 refrigerant-fuelled variable refrigerant flow (VRF) solutions, Multi V S. As one of the first single-fan R32-fueled VRF solutions to enter the market, the volume of LG’s Multi V S has been reduced by approximately 40% and the weight by approximately 23%, making installations in smaller spaces possible. The Multi V S only requires 4.3kg of R32 compared to the previously required 5.6kg. The new Multi V S operates at a noise level of approximately 50-52dBs (A), which can be compared to the sound of normal conversation. Its high efficiency is due to the inclusion of LG’s R1 compressorTM, making it a more eco-conscious cooling solution. The use of the lower GWP refrigerant R32 is another key feature of the new Multi V S, with a GWP that’s approximately 68% lower than that of the most widely-used R410A refrigerant. LG’s Multi V S’s internal heat exchanger includes enhanced corrosion resistance with LG’s Black Fin technology, providing stronger protection to air pollution and salt contamination.

DHD Cooling, working with Galebreaker, is expanding its range of wind and weather protection systems.
Galebreaker develops CFD modelling techniques to accurately model power plants to determine the right position and porosity of wind reduction systems. In addition to the extensive installed base of ACC wind protection screens
further developments include solutions for large natural draft cooling towers which can prevent the potentially damaging build-up of ice. Air inlet filtration solutions provide benefits to both wet and dry cooling systems, either protecting coils from airborne contamination, or reducing the amount of contamination drawn into operating cooling towers. Other performance enhancement systems include plume abated cooling tower rolling doors that are easy to maintain and install. External protection systems include weather shielding of large open structures. These systems are cheaper than cladding and offer wind speed reduction whilst allowing light into buildings. With a wide range of fixed and rolling systems, manually or automatically
deployed, a full range of mesh screens to suit any application, and full engineering and installation services, there is a solution to help any organisation.
