Aggreko


Cold storage warehouses will be able to immediately recover from breakdowns with Aggreko’s new temporary air cooled low temperature AC units.


Delivering 100kW of design cooling capacity at -22°C air outlet temperature,


the machine is a plug and play solution housed in a 20ft container. The temporary solution ensures stored refrigerated products are safeguarded thanks to Aggreko’s 24/7 emergency response team, removing the hassle and cost of moving stock. Available as an air- or water-cooled machine, it can cool down existing cold stores to freezing temperatures as low as -40°C, helping the cold storage and logistics industry to blast freeze during peak production or in case of emergency. The unit is installed outside, increasing safety and avoiding costly installation fees. The units also allow for temporary cooling during planned shutdowns, allowing the operation of the cold store to continue while a fi xed cooling installation is being maintained or upgraded. www.aggreko.com


Dunham-Bush’s Helios ACHX-B Series chillers have been developed to feature excellent energy effi ciency, low noise levels and compact dimensions.


There are 14 models in the range, with cooling capacities ranging from 299kW to 1090kW.


All models are equipped with single or twin screw compressors and are designed for ambient conditions up to 46°C. Key features of the series include independent refrigerant circuits on both single and twin compressor confi gurations, as well as an economiser cycle fi tted as standard in order to maximise energy effi ciency.


Flooded type shell and tube evaporators, combined with stepless unloading via a slide valve arrangement, ensure optimum performance at all load levels


The robust design of the Helios ACHX-B Series ensures these chillers can operate in a wide range of conditions, and full microprocessor control comes as standard.


In addition to its extensive range of chillers, Dunham-Bush also


off ers precision computer room air conditioners, water and air cooled rooftop units, packaged units and a comprehensive range of air handling units.

Armstrong


Armstrong Fluid Technology has announced the release of the new Integrated Pumping System (IPS 4000), an automation solution for commercial HVAC pumping stations of up to eight pumps and 16 zones.


The new IPS 4000 automates and optimises multi-pump installations in a range of diff erent plant confi gurations. Providing sequences for variable primary, secondary or tertiary pumping system applications, it delivers signifi cant energy savings using Armstrong’s patented Parallel SensorlessTM Pump Control technology. Pre-confi gured to leverage the capabilities of Design Envelope (the technology embedded in Armstrong pumps) the new IPS 4000 off ers fast and simple set-up for the most cost eff ective and effi cient pump control results.


Designed for control of multiple pumps in both heating and cooling HVAC applications, it is capable of maximising the performance profi les of up to eight variable speed pumps and up to 12 zones, and is suitable for both new installations and retrofi t.


The IPS 4000 integrates with building management systems (BMS) but can also provide highly eff ective standalone pump control where a BMS is not deployed.
